# Contributing
|
|
||||||
|
|
||||||
Thank you for being interested in contributing to HTTPX.
|
|
||||||
There are many ways you can contribute to the project:
|
|
||||||
|
|
||||||
- Try HTTPX and [report bugs/issues you find](https://github.com/encode/httpx/issues/new)
|
|
||||||
- [Implement new features](https://github.com/encode/httpx/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22)
|
|
||||||
- [Review Pull Requests of others](https://github.com/encode/httpx/pulls)
|
|
||||||
- Write documentation
|
|
||||||
- Participate in discussions
|
|
||||||
|
|
||||||
## Reporting Bugs or Other Issues
|
|
||||||
|
|
||||||
Found something that HTTPX should support?
|
|
||||||
Stumbled upon some unexpected behaviour?
|
|
||||||
|
|
||||||
Contributions should generally start out with [a discussion](https://github.com/encode/httpx/discussions).
|
|
||||||
Possible bugs may be raised as a "Potential Issue" discussion, feature requests may
|
|
||||||
be raised as an "Ideas" discussion. We can then determine if the discussion needs
|
|
||||||
to be escalated into an "Issue" or not, or if we'd consider a pull request.
|
|
||||||
|
|
||||||
Try to be more descriptive as you can and in case of a bug report,
|
|
||||||
provide as much information as possible like:
|
|
||||||
|
|
||||||
- OS platform
|
|
||||||
- Python version
|
|
||||||
- Installed dependencies and versions (`python -m pip freeze`)
|
|
||||||
- Code snippet
|
|
||||||
- Error traceback
|
|
||||||
|
|
||||||
You should always try to reduce any examples to the *simplest possible case*
|
|
||||||
that demonstrates the issue.
|
|
||||||
|
|
||||||
Some possibly useful tips for narrowing down potential issues...
|
|
||||||
|
|
||||||
- Does the issue exist on HTTP/1.1, or HTTP/2, or both?
|
|
||||||
- Does the issue exist with `Client`, `AsyncClient`, or both?
|
|
||||||
- When using `AsyncClient` does the issue exist when using `asyncio` or `trio`, or both?
|
|
||||||
|
|
||||||
## Development
|
|
||||||
|
|
||||||
To start developing HTTPX create a **fork** of the
|
|
||||||
[HTTPX repository](https://github.com/encode/httpx) on GitHub.
|
|
||||||
|
|
||||||
Then clone your fork with the following command replacing `YOUR-USERNAME` with
|
|
||||||
your GitHub username:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ git clone https://github.com/YOUR-USERNAME/httpx
|
|
||||||
```
|
|
||||||
|
|
||||||
You can now install the project and its dependencies using:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ cd httpx
|
|
||||||
$ scripts/install
|
|
||||||
```
|
|
||||||
|
|
||||||
## Testing and Linting
|
|
||||||
|
|
||||||
We use custom shell scripts to automate testing, linting,
|
|
||||||
and documentation building workflow.
|
|
||||||
|
|
||||||
To run the tests, use:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/test
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! warning
|
|
||||||
The test suite spawns testing servers on ports **8000** and **8001**.
|
|
||||||
Make sure these are not in use, so the tests can run properly.
|
|
||||||
|
|
||||||
You can run a single test script like this:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/test -- tests/test_multipart.py
|
|
||||||
```
|
|
||||||
|
|
||||||
To run the code auto-formatting:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/lint
|
|
||||||
```
|
|
||||||
|
|
||||||
Lastly, to run code checks separately (they are also run as part of `scripts/test`), run:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/check
|
|
||||||
```
|
|
||||||
|
|
||||||
## Documenting
|
|
||||||
|
|
||||||
Documentation pages are located under the `docs/` folder.
|
|
||||||
|
|
||||||
To run the documentation site locally (useful for previewing changes), use:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/docs
|
|
||||||
```
|
|
||||||
|
|
||||||
## Resolving Build / CI Failures
|
|
||||||
|
|
||||||
Once you've submitted your pull request, the test suite will automatically run, and the results will show up in GitHub.
|
|
||||||
If the test suite fails, you'll want to click through to the "Details" link, and try to identify why the test suite failed.
|
|
||||||

|
||||||

||||||
<img src="https://raw.githubusercontent.com/encode/httpx/master/docs/img/gh-actions-fail.png" alt='Failing PR commit status'>
|
|
||||||
</p>
|
|
||||||
|
|
||||||
Here are some common ways the test suite can fail:
|
|
||||||
|
|
||||||
### Check Job Failed
|
|
||||||
|
|
||||||
<p align="center" style="margin: 0 0 10px">
|
|
||||||
<img src="https://raw.githubusercontent.com/encode/httpx/master/docs/img/gh-actions-fail-check.png" alt='Failing GitHub action lint job'>
|
|
||||||
</p>
|
|
||||||
|
|
||||||
This job failing means there is either a code formatting issue or type-annotation issue.
|
|
||||||
You can look at the job output to figure out why it's failed or within a shell run:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/check
|
|
||||||
```
|
|
||||||
|
|
||||||
It may be worth it to run `$ scripts/lint` to attempt auto-formatting the code
|
|
||||||
and if that job succeeds commit the changes.
|
|
||||||
|
|
||||||
### Docs Job Failed
|
|
||||||
|
|
||||||
This job failing means the documentation failed to build. This can happen for
|
|
||||||
a variety of reasons like invalid markdown or missing configuration within `mkdocs.yml`.
|
|
||||||
|
|
||||||
### Python 3.X Job Failed
|
|
||||||
|
|
||||||
<p align="center" style="margin: 0 0 10px">
|
|
||||||
<img src="https://raw.githubusercontent.com/encode/httpx/master/docs/img/gh-actions-fail-test.png" alt='Failing GitHub action test job'>
|
|
||||||
</p>
|
|
||||||
|
|
||||||
This job failing means the unit tests failed or not all code paths are covered by unit tests.
|
|
||||||
|
|
||||||
If tests are failing you will see this message under the coverage report:
|
|
||||||
|
|
||||||
`=== 1 failed, 435 passed, 1 skipped, 1 xfailed in 11.09s ===`
|
|
||||||
|
|
||||||
If tests succeed but coverage doesn't reach our current threshold, you will see this
|
|
||||||
message under the coverage report:
|
|
||||||
|
|
||||||
`FAIL Required test coverage of 100% not reached. Total coverage: 99.00%`
|
|
||||||
|
|
||||||
## Releasing
|
|
||||||
|
|
||||||
*This section is targeted at HTTPX maintainers.*
|
|
||||||
|
|
||||||
Before releasing a new version, create a pull request that includes:
|
|
||||||
|
|
||||||
- **An update to the changelog**:
|
|
||||||
- We follow the format from [keepachangelog](https://keepachangelog.com/en/1.0.0/).
|
|
||||||
- [Compare](https://github.com/encode/httpx/compare/) `master` with the tag of the latest release, and list all entries that are of interest to our users:
|
|
||||||
- Things that **must** go in the changelog: added, changed, deprecated or removed features, and bug fixes.
|
|
||||||
- Things that **should not** go in the changelog: changes to documentation, tests or tooling.
|
|
||||||
- Try sorting entries in descending order of impact / importance.
|
|
||||||
- Keep it concise and to-the-point. 🎯
|
|
||||||
- **A version bump**: see `__version__.py`.
|
|
||||||
|
|
||||||
For an example, see [#1006](https://github.com/encode/httpx/pull/1006).
|
|
||||||
|
|
||||||
Once the release PR is merged, create a
|
|
||||||
[new release](https://github.com/encode/httpx/releases/new) including:
|
|
||||||
|
|
||||||
- Tag version like `0.13.3`.
|
|
||||||
- Release title `Version 0.13.3`
|
|
||||||
- Description copied from the changelog.
|
|
||||||
|
|
||||||
Once created this release will be automatically uploaded to PyPI.
|
|
||||||
|
|
||||||
If something goes wrong with the PyPI job the release can be published using the
|
|
||||||
`scripts/publish` script.
|
|
||||||
|
|
||||||
## Development proxy setup
|
|
||||||
|
|
||||||
To test and debug requests via a proxy it's best to run a proxy server locally.
|
|
||||||
Any server should do but HTTPCore's test suite uses
|
|
||||||
[`mitmproxy`](https://mitmproxy.org/) which is written in Python, it's fully
|
|
||||||
featured and has excellent UI and tools for introspection of requests.
|
|
||||||
|
|
||||||
You can install `mitmproxy` using `pip install mitmproxy` or [several
|
|
||||||
other ways](https://docs.mitmproxy.org/stable/overview-installation/).
|
|
||||||
|
|
||||||
`mitmproxy` does require setting up local TLS certificates for HTTPS requests,
|
|
||||||
as its main purpose is to allow developers to inspect requests that pass through
|
|
||||||
it. We can set them up follows:
|
|
||||||
|
|
||||||
1. [`pip install trustme-cli`](https://github.com/sethmlarson/trustme-cli/).
|
|
||||||
2. `trustme-cli -i example.org www.example.org`, assuming you want to test
|
|
||||||
connecting to that domain, this will create three files: `server.pem`,
|
|
||||||
`server.key` and `client.pem`.
|
|
||||||
3. `mitmproxy` requires a PEM file that includes the private key and the
|
|
||||||
certificate so we need to concatenate them:
|
|
||||||
`cat server.key server.pem > server.withkey.pem`.
|
|
||||||
4. Start the proxy server `mitmproxy --certs server.withkey.pem`, or use the
|
|
||||||
[other mitmproxy commands](https://docs.mitmproxy.org/stable/) with different
|
|
||||||
UI options.
|
|
||||||
|
|
||||||
At this point the server is ready to start serving requests, you'll need to
|
|
||||||
configure HTTPX as described in the
|
|
||||||
[proxy section](https://www.python-httpx.org/advanced/#http-proxying) and
|
|
||||||
the [SSL certificates section](https://www.python-httpx.org/advanced/#ssl-certificates),
|
|
||||||
this is where our previously generated `client.pem` comes in:
|
|
||||||
|
|
||||||
```
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
ssl_context = httpx.SSLContext()
|
|
||||||
ssl_context.load_verify_locations("/path/to/client.pem")
|
|
||||||
|
|
||||||
with httpx.Client(proxy="http://127.0.0.1:8080/", ssl_context=ssl_context) as client:
|
|
||||||
response = client.get("https://example.org")
|
|
||||||
print(response.status_code) # should print 200
|
|
||||||
```
|
|
||||||
|
|
||||||
Note, however, that HTTPS requests will only succeed to the host specified
|
|
||||||
in the SSL/TLS certificate we generated, HTTPS requests to other hosts will
|
|
||||||
raise an error like:
|
|
||||||
|
|
||||||
```
|
|
||||||
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate
|
|
||||||
verify failed: Hostname mismatch, certificate is not valid for
|
|
||||||
'duckduckgo.com'. (_ssl.c:1108)
|
|
||||||
```
|
|
||||||
|
|
||||||
If you want to make requests to more hosts you'll need to regenerate the
|
|
||||||
certificates and include all the hosts you intend to connect to in the
|
|
||||||
seconds step, i.e.
|
|
||||||
|
|
||||||
`trustme-cli -i example.org www.example.org duckduckgo.com www.duckduckgo.com`

|
|
||||||
## Dependencies
|
|
||||||
|
|
||||||
The HTTPX project relies on these excellent libraries:
|
|
||||||
|
|
||||||
* `httpcore` - The underlying transport implementation for `httpx`.
|
|
||||||
* `h11` - HTTP/1.1 support.
|
|
||||||
* `certifi` - SSL certificates.
|
|
||||||
* `idna` - Internationalized domain name support.
|
|
||||||
* `sniffio` - Async library autodetection.
|
|
||||||
|
|
||||||
As well as these optional installs:
|
|
||||||
|
|
||||||
* `h2` - HTTP/2 support. *(Optional, with `httpx[http2]`)*
|
|
||||||
* `socksio` - SOCKS proxy support. *(Optional, with `httpx[socks]`)*
|
|
||||||
* `rich` - Rich terminal support. *(Optional, with `httpx[cli]`)*
|
|
||||||
* `click` - Command line client support. *(Optional, with `httpx[cli]`)*
|
|
||||||
* `brotli` or `brotlicffi` - Decoding for "brotli" compressed responses. *(Optional, with `httpx[brotli]`)*
|
|
||||||
* `zstandard` - Decoding for "zstd" compressed responses. *(Optional, with `httpx[zstd]`)*
|
|
||||||
|
|
||||||
A huge amount of credit is due to `requests` for the API layout that
|
|
||||||
much of this work follows, as well as to `urllib3` for plenty of design
|
|
||||||
inspiration around the lower-level networking details.

Authentication can either be included on a per-request basis...
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.BasicAuth(username="username", password="secret")
|
|
||||||
>>> client = httpx.Client()
|
|
||||||
>>> response = client.get("https://www.example.com/", auth=auth)
|
|
||||||
```
|
|
||||||
|
|
||||||
Or configured on the client instance, ensuring that all outgoing requests will include authentication credentials...
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.BasicAuth(username="username", password="secret")
|
|
||||||
>>> client = httpx.Client(auth=auth)
|
|
||||||
>>> response = client.get("https://www.example.com/")
|
|
||||||
```
|
|
||||||
|
|
||||||
## Basic authentication
|
|
||||||
|
|
||||||
HTTP basic authentication is an unencrypted authentication scheme that uses a simple encoding of the username and password in the request `Authorization` header. Since it is unencrypted it should typically only be used over `https`, although this is not strictly enforced.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.BasicAuth(username="finley", password="secret")
|
|
||||||
>>> client = httpx.Client(auth=auth)
|
|
||||||
>>> response = client.get("https://httpbin.org/basic-auth/finley/secret")
|
|
||||||
>>> response
|
|
||||||
<Response [200 OK]>
|
|
||||||
```
|
|
||||||
|
|
||||||
## Digest authentication
|
|
||||||
|
|
||||||
HTTP digest authentication is a challenge-response authentication scheme. Unlike basic authentication it provides encryption, and can be used over unencrypted `http` connections. It requires an additional round-trip in order to negotiate the authentication.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.DigestAuth(username="olivia", password="secret")
|
|
||||||
>>> client = httpx.Client(auth=auth)
|
|
||||||
>>> response = client.get("https://httpbin.org/digest-auth/auth/olivia/secret")
|
|
||||||
>>> response
|
|
||||||
<Response [200 OK]>
|
|
||||||
>>> response.history
|
|
||||||
[<Response [401 UNAUTHORIZED]>]
|
|
||||||
```
|
|
||||||
|
|
||||||
## NetRC authentication
|
|
||||||
|
|
||||||
HTTPX can be configured to use [a `.netrc` config file](https://everything.curl.dev/usingcurl/netrc) for authentication.
|
|
||||||
|
|
||||||
The `.netrc` config file allows authentication credentials to be associated with specified hosts. When a request is made to a host that is found in the netrc file, the username and password will be included using HTTP basic authentication.
|
|
||||||
|
|
||||||
Example `.netrc` file:
|
|
||||||
|
|
||||||
```
|
|
||||||
machine example.org
|
|
||||||
login example-username
|
|
||||||
password example-password
|
|
||||||
|
|
||||||
machine python-httpx.org
|
|
||||||
login other-username
|
|
||||||
password other-password
|
|
||||||
```
|
|
||||||
|
|
||||||
Some examples of configuring `.netrc` authentication with `httpx`.
|
|
||||||
|
|
||||||
Use the default `.netrc` file in the users home directory:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.NetRCAuth()
|
|
||||||
>>> client = httpx.Client(auth=auth)
|
|
||||||
```
|
|
||||||
|
|
||||||
Use an explicit path to a `.netrc` file:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.NetRCAuth(file="/path/to/.netrc")
|
|
||||||
>>> client = httpx.Client(auth=auth)
|
|
||||||
```
|
|
||||||
|
|
||||||
Use the `NETRC` environment variable to configure a path to the `.netrc` file,
|
|
||||||
or fallback to the default.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.NetRCAuth(file=os.environ.get("NETRC"))
|
|
||||||
>>> client = httpx.Client(auth=auth)
|
|
||||||
```
|
|
||||||
|
|
||||||
The `NetRCAuth()` class uses [the `netrc.netrc()` function from the Python standard library](https://docs.python.org/3/library/netrc.html). See the documentation there for more details on exceptions that may be raised if the `.netrc` file is not found, or cannot be parsed.
|
|
||||||
|
|
||||||
## Custom authentication schemes
|
|
||||||
|
|
||||||
When issuing requests or instantiating a client, the `auth` argument can be used to pass an authentication scheme to use. The `auth` argument may be one of the following...
|
|
||||||
|
|
||||||
* A two-tuple of `username`/`password`, to be used with basic authentication.
|
|
||||||
* An instance of `httpx.BasicAuth()`, `httpx.DigestAuth()`, or `httpx.NetRCAuth()`.
|
|
||||||
* A callable, accepting a request and returning an authenticated request instance.
|
|
||||||
* An instance of subclasses of `httpx.Auth`.
|
|
||||||
|
|
||||||
The most involved of these is the last, which allows you to create authentication flows involving one or more requests. A subclass of `httpx.Auth` should implement `def auth_flow(request)`, and yield any requests that need to be made...
|
|
||||||
|
|
||||||
```python
|
|
||||||
class MyCustomAuth(httpx.Auth):
|
|
||||||
def __init__(self, token):
|
|
||||||
self.token = token
|
|
||||||
|
|
||||||
def auth_flow(self, request):
|
|
||||||
# Send the request, with a custom `X-Authentication` header.
|
|
||||||
request.headers['X-Authentication'] = self.token
|
|
||||||
yield request
|
|
||||||
```
|
|
||||||
|
|
||||||
If the auth flow requires more than one request, you can issue multiple yields, and obtain the response in each case...
|
|
||||||
|
|
||||||
```python
|
|
||||||
class MyCustomAuth(httpx.Auth):
|
|
||||||
def __init__(self, token):
|
|
||||||
self.token = token
|
|
||||||
|
|
||||||
def auth_flow(self, request):
|
|
||||||
response = yield request
|
|
||||||
if response.status_code == 401:
|
|
||||||
# If the server issues a 401 response then resend the request,
|
|
||||||
# with a custom `X-Authentication` header.
|
|
||||||
request.headers['X-Authentication'] = self.token
|
|
||||||
yield request
|
|
||||||
```
|
|
||||||
|
|
||||||
Custom authentication classes are designed to not perform any I/O, so that they may be used with both sync and async client instances. If you are implementing an authentication scheme that requires the request body, then you need to indicate this on the class using a `requires_request_body` property.
|
|
||||||
|
|
||||||
You will then be able to access `request.content` inside the `.auth_flow()` method.
|
|
||||||
|
|
||||||
```python
|
|
||||||
class MyCustomAuth(httpx.Auth):
|
|
||||||
requires_request_body = True
|
|
||||||
|
|
||||||
def __init__(self, token):
|
|
||||||
self.token = token
|
|
||||||
|
|
||||||
def auth_flow(self, request):
|
|
||||||
response = yield request
|
|
||||||
if response.status_code == 401:
|
|
||||||
# If the server issues a 401 response then resend the request,
|
|
||||||
# with a custom `X-Authentication` header.
|
|
||||||
request.headers['X-Authentication'] = self.sign_request(...)
|
|
||||||
yield request
|
|
||||||
|
|
||||||
def sign_request(self, request):
|
|
||||||
# Create a request signature, based on `request.method`, `request.url`,
|
|
||||||
# `request.headers`, and `request.content`.
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
Similarly, if you are implementing a scheme that requires access to the response body, then use the `requires_response_body` property. You will then be able to access response body properties and methods such as `response.content`, `response.text`, `response.json()`, etc.
|
|
||||||
|
|
||||||
```python
|
|
||||||
class MyCustomAuth(httpx.Auth):
|
|
||||||
requires_response_body = True
|
|
||||||
|
|
||||||
def __init__(self, access_token, refresh_token, refresh_url):
|

If you _do_ need to perform I/O other than HTTP requests, such as accessing a disk-based cache, or you need to use concurrency primitives, such as locks, then you should override `.sync_auth_flow()` and `.async_auth_flow()` (instead of `.auth_flow()`). The former will be used by `httpx.Client`, while the latter will be used by `httpx.AsyncClient`.
|
|
||||||
|
|
||||||
```python
|
|
||||||
import asyncio
|
|
||||||
import threading
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
|
|
||||||
class MyCustomAuth(httpx.Auth):
|
|
||||||
def __init__(self):
|
|
||||||
self._sync_lock = threading.RLock()

|
||||||
self._async_lock = asyncio.Lock()
|

||||||

|
||||||
def sync_get_token(self):

|

||||||

|
||||||
def sync_auth_flow(self, request):
|
|
||||||
token = self.sync_get_token()
|
|
||||||
request.headers["Authorization"] = f"Token {token}"
|
|

token = await self.async_get_token()
|

request.headers["Authorization"] = f"Token {token}"
|
|
||||||
yield request
|
|
||||||
```
|
|
||||||
|
|
||||||
If you only want to support one of the two methods, then you should still override it, but raise an explicit `RuntimeError`.

!!! hint
|
|
||||||
If you are coming from Requests, `httpx.Client()` is what you can use instead of `requests.Session()`.
|
|
||||||
|
|
||||||
## Why use a Client?
|
|
||||||
|
|
||||||
!!! note "TL;DR"
|
|
||||||
If you do anything more than experimentation, one-off scripts, or prototypes, then you should use a `Client` instance.
|
|
||||||
|
|
||||||
**More efficient usage of network resources**
|
|
||||||
|
|
||||||
When you make requests using the top-level API as documented in the [Quickstart](../quickstart.md) guide, HTTPX has to establish a new connection _for every single request_ (connections are not reused). As the number of requests to a host increases, this quickly becomes inefficient.
|
|
||||||
|
|
||||||
On the other hand, a `Client` instance uses [HTTP connection pooling](https://en.wikipedia.org/wiki/HTTP_persistent_connection). This means that when you make several requests to the same host, the `Client` will reuse the underlying TCP connection, instead of recreating one for every single request.
|
|
||||||
|
|
||||||
This can bring **significant performance improvements** compared to using the top-level API, including:
|
|
||||||
|
|
||||||
- Reduced latency across requests (no handshaking).
|
|
||||||
- Reduced CPU usage and round-trips.
|
|
||||||
- Reduced network congestion.
|
|
||||||
|
|
||||||
**Extra features**
|
|
||||||
|
|
||||||
`Client` instances also support features that aren't available at the top-level API, such as:
|
|
||||||
|
|
||||||
- Cookie persistence across requests.
|
|
||||||
- Applying configuration across all outgoing requests.
|
|
||||||
- Sending requests through HTTP proxies.
|
|
||||||
- Using [HTTP/2](../http2.md).
|
|
||||||
|
|
||||||
The other sections on this page go into further detail about what you can do with a `Client` instance.
|
|
||||||
|
|
||||||
## Usage
|
|
||||||
|
|
||||||
The recommended way to use a `Client` is as a context manager. This will ensure that connections are properly cleaned up when leaving the `with` block:
|
|
||||||
|
|
||||||
```python
|
|
||||||
with httpx.Client() as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
Alternatively, you can explicitly close the connection pool without block-usage using `.close()`:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client()
|
|
||||||
try:
|
|
||||||
...
|
|
||||||
finally:
|
|
||||||
client.close()
|
|
||||||
```
|
|
||||||
|
|
||||||
## Making requests
|
|
||||||
|
|
||||||
Once you have a `Client`, you can send requests using `.get()`, `.post()`, etc. For example:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with httpx.Client() as client:
|
|
||||||
... r = client.get('https://example.com')
|
|
||||||
...
|
|
||||||
>>> r
|
|
||||||
<Response [200 OK]>
|
|
||||||
```
|
|
||||||
|
|
||||||
These methods accept the same arguments as `httpx.get()`, `httpx.post()`, etc. This means that all features documented in the [Quickstart](../quickstart.md) guide are also available at the client level.
|
|
||||||
|
|
||||||
For example, to send a request with custom headers:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with httpx.Client() as client:
|
|
||||||
... headers = {'X-Custom': 'value'}
|
|
||||||
... r = client.get('https://example.com', headers=headers)
|
|
||||||
...
|
|
||||||
>>> r.request.headers['X-Custom']
|
|
||||||
'value'
|
|
||||||
```
|
|
||||||
|
|
||||||
## Sharing configuration across requests
|
|
||||||
|
|
||||||
Clients allow you to apply configuration to all outgoing requests by passing parameters to the `Client` constructor.
|
|
||||||
|
|
||||||
For example, to apply a set of custom headers _on every request_:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> url = 'http://httpbin.org/headers'
|
|
||||||
>>> headers = {'user-agent': 'my-app/0.0.1'}
|
|
||||||
>>> with httpx.Client(headers=headers) as client:
|
|
||||||
... r = client.get(url)
|
|
||||||
...
|
|
||||||
>>> r.json()['headers']['User-Agent']
|
|
||||||
'my-app/0.0.1'
|
|
||||||
```
|
|
||||||
|
|
||||||
## Merging of configuration
|
|
||||||
|
|
||||||
When a configuration option is provided at both the client-level and request-level, one of two things can happen:
|
|
||||||
|
|
||||||
- For headers, query parameters and cookies, the values are combined together. For example:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> headers = {'X-Auth': 'from-client'}
|
|
||||||
>>> params = {'client_id': 'client1'}
|
|
||||||
>>> with httpx.Client(headers=headers, params=params) as client:
|
|
||||||
... headers = {'X-Custom': 'from-request'}
|
|
||||||
... params = {'request_id': 'request1'}
|
|
||||||
... r = client.get('https://example.com', headers=headers, params=params)
|
|
||||||
...
|
|
||||||
>>> r.request.url
|
|
||||||
URL('https://example.com?client_id=client1&request_id=request1')
|
|
||||||
>>> r.request.headers['X-Auth']
|
|
||||||
'from-client'
|
|
||||||
>>> r.request.headers['X-Custom']
|
|
||||||
'from-request'
|
|
||||||
```
|
|
||||||
|
|
||||||
- For all other parameters, the request-level value takes priority. For example:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with httpx.Client(auth=('tom', 'mot123')) as client:
|
|
||||||
... r = client.get('https://example.com', auth=('alice', 'ecila123'))
|
|
||||||
...
|
|
||||||
>>> _, _, auth = r.request.headers['Authorization'].partition(' ')
|
|
||||||
>>> import base64
|
|
||||||
>>> base64.b64decode(auth)
|
|
||||||
b'alice:ecila123'
|
|
||||||
```
|
|
||||||
|
|
||||||
If you need finer-grained control on the merging of client-level and request-level parameters, see [Request instances](#request-instances).
|
|
||||||
|
|
||||||
## Other Client-only configuration options
|
|
||||||
|
|
||||||
Additionally, `Client` accepts some configuration options that aren't available at the request level.
|
|
||||||
|
|
||||||
For example, `base_url` allows you to prepend an URL to all outgoing requests:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with httpx.Client(base_url='http://httpbin.org') as client:
|
|
||||||
... r = client.get('/headers')
|
|
||||||
...
|
|
||||||
>>> r.request.url
|
|
||||||
URL('http://httpbin.org/headers')
|
|
||||||
```
|
|
||||||
|
|
||||||
For a list of all available client parameters, see the [`Client`](../api.md#client) API reference.
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
## Request instances
|
|
||||||
|
|
||||||
For maximum control on what gets sent over the wire, HTTPX supports building explicit [`Request`](../api.md#request) instances:
|
|
||||||
|
|
||||||
```python
|
|
||||||
request = httpx.Request("GET", "https://example.com")
|
|
||||||
```
|
|
||||||
|
|
||||||
To dispatch a `Request` instance across to the network, create a [`Client` instance](#client-instances) and use `.send()`:
|
|
||||||
|
|
||||||
```python
|
|
||||||
with httpx.Client() as client:
|
|
||||||
response = client.send(request)
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
If you need to mix client-level and request-level options in a way that is not supported by the default [Merging of parameters](#merging-of-parameters), you can use `.build_request()` and then make arbitrary modifications to the `Request` instance. For example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
headers = {"X-Api-Key": "...", "X-Client-ID": "ABC123"}
|
|
||||||
|
|
||||||
with httpx.Client(headers=headers) as client:
|
|
||||||
request = client.build_request("GET", "https://api.example.com")
|
|
||||||
|
|
||||||
print(request.headers["X-Client-ID"]) # "ABC123"
|
|
||||||
|
|
||||||
# Don't send the API key for this particular request.
|
|
||||||
del request.headers["X-Api-Key"]
|
|
||||||
|
|
||||||
response = client.send(request)
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
## Monitoring download progress
|
|
||||||
|
|
||||||
If you need to monitor download progress of large responses, you can use response streaming and inspect the `response.num_bytes_downloaded` property.
|
|
||||||
|
|
||||||
This interface is required for properly determining download progress, because the total number of bytes returned by `response.content` or `response.iter_content()` will not always correspond with the raw content length of the response if HTTP response compression is being used.
|
|
||||||
|
|
||||||
For example, showing a progress bar using the [`tqdm`](https://github.com/tqdm/tqdm) library while a response is being downloaded could be done like this…
|
|
||||||
|
|
||||||
```python
|
|
||||||
import tempfile
|
|
||||||
|
|
||||||
import httpx
|
|
||||||
from tqdm import tqdm
|
|
||||||
|
|
||||||
with tempfile.NamedTemporaryFile() as download_file:
|
|
||||||
url = "https://speed.hetzner.de/100MB.bin"
|
|
||||||
with httpx.stream("GET", url) as response:
|
|
||||||
total = int(response.headers["Content-Length"])
|
|
||||||
|
|
||||||
with tqdm(total=total, unit_scale=True, unit_divisor=1024, unit="B") as progress:
|
|
||||||
num_bytes_downloaded = response.num_bytes_downloaded
|
|
||||||
for chunk in response.iter_bytes():
|
|
||||||
download_file.write(chunk)
|
|
||||||
progress.update(response.num_bytes_downloaded - num_bytes_downloaded)
|
|
||||||
num_bytes_downloaded = response.num_bytes_downloaded
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
Or an alternate example, this time using the [`rich`](https://github.com/willmcgugan/rich) library…
|
|
||||||
|
|
||||||
```python
|
|
||||||
import tempfile
|
|
||||||
import httpx
|
|
||||||
import rich.progress
|
|
||||||
|
|
||||||
with tempfile.NamedTemporaryFile() as download_file:
|
|
||||||
url = "https://speed.hetzner.de/100MB.bin"
|
|
||||||
with httpx.stream("GET", url) as response:
|
|
||||||
total = int(response.headers["Content-Length"])
|
|
||||||
|
|
||||||
with rich.progress.Progress(
|
|
||||||
"[progress.percentage]{task.percentage:>3.0f}%",
|
|
||||||
rich.progress.BarColumn(bar_width=None),
|
|
||||||
rich.progress.DownloadColumn(),
|
|
||||||
rich.progress.TransferSpeedColumn(),
|
|
||||||
) as progress:
|
|
||||||
download_task = progress.add_task("Download", total=total)
|
|
||||||
for chunk in response.iter_bytes():
|
|
||||||
download_file.write(chunk)
|
|
||||||
progress.update(download_task, completed=response.num_bytes_downloaded)
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
## Monitoring upload progress
|
|
||||||
|
|
||||||
If you need to monitor upload progress of large responses, you can use request content generator streaming.
|
|
||||||
|
|
||||||
For example, showing a progress bar using the [`tqdm`](https://github.com/tqdm/tqdm) library.
|
|
||||||
|
|
||||||
```python
|
|
||||||
import io
|
|
||||||
import random
|
|
||||||
|
|
||||||
import httpx
|
|
||||||
from tqdm import tqdm
|
|
||||||
|
|
||||||
|
|
||||||
def gen():
|
|
||||||
"""
|
|
||||||
this is a complete example with generated random bytes.
|
|
||||||
you can replace `io.BytesIO` with real file object.
|
|
||||||
"""
|
|
||||||
total = 32 * 1024 * 1024 # 32m
|
|
||||||
with tqdm(ascii=True, unit_scale=True, unit='B', unit_divisor=1024, total=total) as bar:
|
|
||||||
with io.BytesIO(random.randbytes(total)) as f:
|
|
||||||
while data := f.read(1024):
|
|
||||||
yield data
|
|
||||||
bar.update(len(data))
|
|
||||||
|
|
||||||
|
|
||||||
httpx.post("https://httpbin.org/post", content=gen())
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
|
|
||||||
## Multipart file encoding
|
|
||||||
|
|
||||||
As mentioned in the [quickstart](../quickstart.md#sending-multipart-file-uploads)
|
|
||||||
multipart file encoding is available by passing a dictionary with the
|
|
||||||
name of the payloads as keys and either tuple of elements or a file-like object or a string as values.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with open('report.xls', 'rb') as report_file:
|
|
||||||
... files = {'upload-file': ('report.xls', report_file, 'application/vnd.ms-excel')}
|
|
||||||
... r = httpx.post("https://httpbin.org/post", files=files)
|
|
||||||
>>> print(r.text)
|
|
||||||
{
|
|
||||||
...
|
|
||||||
"files": {
|
|
||||||
"upload-file": "<... binary content ...>"
|
|
||||||
},
|
|
||||||
...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
More specifically, if a tuple is used as a value, it must have between 2 and 3 elements:
|
|
||||||
|
|
||||||
- The first element is an optional file name which can be set to `None`.
|
|
||||||
- The second element may be a file-like object or a string which will be automatically
|
|
||||||
encoded in UTF-8.
|
|
||||||
- An optional third element can be used to specify the
|
|
||||||
[MIME type](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_Types)
|
|
||||||
of the file being uploaded. If not specified HTTPX will attempt to guess the MIME type based
|
|
||||||
on the file name, with unknown file extensions defaulting to "application/octet-stream".
|
|
||||||
If the file name is explicitly set to `None` then HTTPX will not include a content-type
|
|
||||||
MIME header field.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> files = {'upload-file': (None, 'text content', 'text/plain')}
|
|
||||||
>>> r = httpx.post("https://httpbin.org/post", files=files)
|
|
||||||
>>> print(r.text)
|
|
||||||
{
|
|
||||||
...
|
|
||||||
"files": {},
|
|
||||||
"form": {
|
|
||||||
"upload-file": "text-content"
|
|
||||||
},
|
|
||||||
...
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! tip
|
|
||||||
It is safe to upload large files this way. File uploads are streaming by default, meaning that only one chunk will be loaded into memory at a time.
|
|
||||||
|
|
||||||
Non-file data fields can be included in the multipart form using by passing them to `data=...`.
|
|
||||||
|
|
||||||
You can also send multiple files in one go with a multiple file field form.
|
|
||||||
To do that, pass a list of `(field, <file>)` items instead of a dictionary, allowing you to pass multiple items with the same `field`.
|
|
||||||
For instance this request sends 2 files, `foo.png` and `bar.png` in one request on the `images` form field:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with open('foo.png', 'rb') as foo_file, open('bar.png', 'rb') as bar_file:
|
|
||||||
... files = [
|
|
||||||
... ('images', ('foo.png', foo_file, 'image/png')),
|
|
||||||
... ('images', ('bar.png', bar_file, 'image/png')),
|
|
||||||
... ]
|
|
||||||
... r = httpx.post("https://httpbin.org/post", files=files)
|
|
||||||
```

HTTPX allows you to register "event hooks" with the client, that are called
|
|
||||||
every time a particular type of event takes place.
|
|
||||||
|
|
||||||
There are currently two event hooks:
|
|
||||||
|
|
||||||
* `request` - Called after a request is fully prepared, but before it is sent to the network. Passed the `request` instance.
|
|
||||||
* `response` - Called after the response has been fetched from the network, but before it is returned to the caller. Passed the `response` instance.

||||||
|
|
||||||
These allow you to install client-wide functionality such as logging, monitoring or tracing.
|
|
||||||
|
|
||||||
```python
|
|
||||||
def log_request(request):
|
|
||||||
print(f"Request event hook: {request.method} {request.url} - Waiting for response")
|
|
||||||
|
|
||||||
def log_response(response):
|
|
||||||
request = response.request
|
|
||||||
print(f"Response event hook: {request.method} {request.url} - Status {response.status_code}")
|
|
||||||
|
|
||||||
client = httpx.Client(event_hooks={'request': [log_request], 'response': [log_response]})
|
|
||||||
```
|
|
||||||
|
|
||||||
You can also use these hooks to install response processing code, such as this
|
|
||||||
example, which creates a client instance that always raises `httpx.HTTPStatusError`
|
|
||||||
on 4xx and 5xx responses.
|
|
||||||
|
|
||||||
```python
|
|
||||||
def raise_on_4xx_5xx(response):
|
|
||||||
response.raise_for_status()
|
|
||||||
|
|
||||||
client = httpx.Client(event_hooks={'response': [raise_on_4xx_5xx]})
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! note
|
|
||||||
Response event hooks are called before determining if the response body
|
|
||||||
should be read or not.
|
|
||||||
|
|
||||||
If you need access to the response body inside an event hook, you'll
|
|
||||||
need to call `response.read()`, or for AsyncClients, `response.aread()`.
|
|
||||||
|
|
||||||
The hooks are also allowed to modify `request` and `response` objects.
|
|
||||||
|
|
||||||
```python
|
|
||||||
def add_timestamp(request):
|
|
||||||
request.headers['x-request-timestamp'] = datetime.now(tz=datetime.utc).isoformat()
|
|
||||||
|
|
||||||
client = httpx.Client(event_hooks={'request': [add_timestamp]})
|
|
||||||
```
|
|
||||||
|
|
||||||
Event hooks must always be set as a **list of callables**, and you may register
|
|
||||||
multiple event hooks for each type of event.
|
|
||||||
|
|
||||||
As well as being able to set event hooks on instantiating the client, there
|
|
||||||
is also an `.event_hooks` property, that allows you to inspect and modify
|
|
||||||
the installed hooks.
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client()
|
|
||||||
client.event_hooks['request'] = [log_request]
|
|
||||||
client.event_hooks['response'] = [log_response, raise_on_4xx_5xx]
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! note
|
|
||||||
If you are using HTTPX's async support, then you need to be aware that
|
|
||||||
hooks registered with `httpx.AsyncClient` MUST be async functions,
|
|
||||||
rather than plain functions.

# Extensions
|
|
||||||
|
|
||||||
Request and response extensions provide a untyped space where additional information may be added.
|
|
||||||
|
|
||||||
Extensions should be used for features that may not be available on all transports, and that do not fit neatly into [the simplified request/response model](https://www.encode.io/httpcore/extensions/) that the underlying `httpcore` package uses as its API.
|
|
||||||
|
|
||||||
Several extensions are supported on the request:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Request timeouts actually implemented as an extension on
|
|
||||||
# the request, ensuring that they are passed throughout the
|
|
||||||
# entire call stack.
|
|
||||||
client = httpx.Client()
|
|
||||||
response = client.get(
|
|
||||||
"https://www.example.com",
|
|
||||||
extensions={"timeout": {"connect": 5.0}}
|
|
||||||
)
|
|
||||||
response.request.extensions["timeout"]
|
|
||||||
{"connect": 5.0}
|
|
||||||
```
|
|
||||||
|
|
||||||
And on the response:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client()
|
|
||||||
response = client.get("https://www.example.com")
|
|
||||||
print(response.extensions["http_version"]) # b"HTTP/1.1"
|
|
||||||
# Other server responses could have been
|
|
||||||
# b"HTTP/0.9", b"HTTP/1.0", or b"HTTP/1.1"
|
|
||||||
```
|
|
||||||
|
|
||||||
## Request Extensions
|
|
||||||
|
|
||||||
### `"trace"`
|
|
||||||
|
|
||||||
The trace extension allows a callback handler to be installed to monitor the internal
|
|
||||||
flow of events within the underlying `httpcore` transport.
|
|
||||||
|
|
||||||
The simplest way to explain this is with an example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
def log(event_name, info):
|
|
||||||
print(event_name, info)
|
|
||||||
|
|
||||||
client = httpx.Client()
|
|
||||||
response = client.get("https://www.example.com/", extensions={"trace": log})
|
|
||||||
# connection.connect_tcp.started {'host': 'www.example.com', 'port': 443, 'local_address': None, 'timeout': None}
|
|
||||||
# connection.connect_tcp.complete {'return_value': <httpcore.backends.sync.SyncStream object at 0x1093f94d0>}
|
|
||||||
# connection.start_tls.started {'ssl_context': <ssl.SSLContext object at 0x1093ee750>, 'server_hostname': b'www.example.com', 'timeout': None}
|
|
||||||
# connection.start_tls.complete {'return_value': <httpcore.backends.sync.SyncStream object at 0x1093f9450>}
|
|
||||||
# http11.send_request_headers.started {'request': <Request [b'GET']>}
|
|
||||||
# http11.send_request_headers.complete {'return_value': None}
|
|
||||||
# http11.send_request_body.started {'request': <Request [b'GET']>}
|
|
||||||
# http11.send_request_body.complete {'return_value': None}
|
|
||||||
# http11.receive_response_headers.started {'request': <Request [b'GET']>}
|
|
||||||
# http11.receive_response_headers.complete {'return_value': (b'HTTP/1.1', 200, b'OK', [(b'Age', b'553715'), (b'Cache-Control', b'max-age=604800'), (b'Content-Type', b'text/html; charset=UTF-8'), (b'Date', b'Thu, 21 Oct 2021 17:08:42 GMT'), (b'Etag', b'"3147526947+ident"'), (b'Expires', b'Thu, 28 Oct 2021 17:08:42 GMT'), (b'Last-Modified', b'Thu, 17 Oct 2019 07:18:26 GMT'), (b'Server', b'ECS (nyb/1DCD)'), (b'Vary', b'Accept-Encoding'), (b'X-Cache', b'HIT'), (b'Content-Length', b'1256')])}
|
|
||||||
# http11.receive_response_body.started {'request': <Request [b'GET']>}
|
|
||||||
# http11.receive_response_body.complete {'return_value': None}
|
|
||||||
# http11.response_closed.started {}
|
|
||||||
# http11.response_closed.complete {'return_value': None}
|
|
||||||
```
|
|
||||||
|
|
||||||
The `event_name` and `info` arguments here will be one of the following:
|
|
||||||
|
|
||||||
* `{event_type}.{event_name}.started`, `<dictionary of keyword arguments>`
|
|
||||||
* `{event_type}.{event_name}.complete`, `{"return_value": <...>}`
|
|
||||||
* `{event_type}.{event_name}.failed`, `{"exception": <...>}`
|
|
||||||
|
|
||||||
Note that when using async code the handler function passed to `"trace"` must be an `async def ...` function.
|
|
||||||
|
|
||||||
The following event types are currently exposed...
|
|
||||||
|
|
||||||
**Establishing the connection**
|
|
||||||
|
|
||||||
* `"connection.connect_tcp"`
|
|
||||||
* `"connection.connect_unix_socket"`
|
|
||||||
* `"connection.start_tls"`
|
|
||||||
|
|
||||||
**HTTP/1.1 events**
|
|
||||||
|
|
||||||
* `"http11.send_request_headers"`
|
|
||||||
* `"http11.send_request_body"`
|
|
||||||
* `"http11.receive_response"`
|
|
||||||
* `"http11.receive_response_body"`
|
|
||||||
* `"http11.response_closed"`
|
|
||||||
|
|
||||||
**HTTP/2 events**
|
|
||||||
|
|
||||||
* `"http2.send_connection_init"`
|
|
||||||
* `"http2.send_request_headers"`
|
|
||||||
* `"http2.send_request_body"`
|
|
||||||
* `"http2.receive_response_headers"`
|
|
||||||
* `"http2.receive_response_body"`
|
|
||||||
* `"http2.response_closed"`
|
|
||||||
|
|
||||||
The exact set of trace events may be subject to change across different versions of `httpcore`. If you need to rely on a particular set of events it is recommended that you pin installation of the package to a fixed version.
|
|
||||||
|
|
||||||
### `"sni_hostname"`
|
|
||||||
|
|
||||||
The server's hostname, which is used to confirm the hostname supplied by the SSL certificate.
|
|
||||||
|
|
||||||
If you want to connect to an explicit IP address rather than using the standard DNS hostname lookup, then you'll need to use this request extension.
|
|
||||||
|
|
||||||
For example:
|
|
||||||
|
|
||||||
``` python
|
|
||||||
# Connect to '185.199.108.153' but use 'www.encode.io' in the Host header,
|
|
||||||
# and use 'www.encode.io' when SSL verifying the server hostname.
|
|
||||||
client = httpx.Client()
|
|
||||||
headers = {"Host": "www.encode.io"}
|
|
||||||
extensions = {"sni_hostname": "www.encode.io"}
|
|
||||||
response = client.get(
|
|
||||||
"https://185.199.108.153/path",
|
|
||||||
headers=headers,
|
|
||||||
extensions=extensions
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
### `"timeout"`
|
|
||||||
|
|
||||||
A dictionary of `str: Optional[float]` timeout values.
|
|
||||||
|
|
||||||
May include values for `'connect'`, `'read'`, `'write'`, or `'pool'`.
|
|
||||||
|
|
||||||
For example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Timeout if a connection takes more than 5 seconds to established, or if
|
|
||||||
# we are blocked waiting on the connection pool for more than 10 seconds.
|
|
||||||
client = httpx.Client()
|
|
||||||
response = client.get(
|
|
||||||
"https://www.example.com",
|
|
||||||
extensions={"timeout": {"connect": 5.0, "pool": 10.0}}
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
This extension is how the `httpx` timeouts are implemented, ensuring that the timeout values are associated with the request instance and passed throughout the stack. You shouldn't typically be working with this extension directly, but use the higher level `timeout` API instead.
|
|
||||||
|
|
||||||
### `"target"`
|
|
||||||
|
|
||||||
The target that is used as [the HTTP target instead of the URL path](https://datatracker.ietf.org/doc/html/rfc2616#section-5.1.2).
|
|
||||||
|
|
||||||
This enables support constructing requests that would otherwise be unsupported.
|
|
||||||
|
|
||||||
* URL paths with non-standard escaping applied.
|
|
||||||
* Forward proxy requests using an absolute URI.
|
|
||||||
* Tunneling proxy requests using `CONNECT` with hostname as the target.
|
|
||||||
* Server-wide `OPTIONS *` requests.
|
|
||||||
|
|
||||||
Some examples:
|
|
||||||
|
|
||||||
Using the 'target' extension to send requests without the standard path escaping rules...
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Typically a request to "https://www.example.com/test^path" would
|
|
||||||
# connect to "www.example.com" and send an HTTP/1.1 request like...
|
|
||||||
#
|
|
||||||
# GET /test%5Epath HTTP/1.1
|
|
||||||
#
|
|
||||||
# Using the target extension we can include the literal '^'...
|
|
||||||
#
|
|
||||||
# GET /test^path HTTP/1.1
|
|
||||||
#
|
|
||||||
# Note that requests must still be valid HTTP requests.
|
|
||||||
# For example including whitespace in the target will raise a `LocalProtocolError`.
|
|
||||||
extensions = {"target": b"/test^path"}
|
|
||||||
response = httpx.get("https://www.example.com", extensions=extensions)
|
|
||||||
```
|
|
||||||
|
|
||||||
The `target` extension also allows server-wide `OPTIONS *` requests to be constructed...
|
|
||||||
|
|
||||||
```python
|
|
||||||
# This will send the following request...
|
|
||||||
#
|
|
||||||
# CONNECT * HTTP/1.1
|
|
||||||
extensions = {"target": b"*"}
|
|
||||||
response = httpx.request("CONNECT", "https://www.example.com", extensions=extensions)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Response Extensions
|
|
||||||
|
|
||||||
### `"http_version"`
|
|
||||||
|
|
||||||
The HTTP version, as bytes. Eg. `b"HTTP/1.1"`.
|
|
||||||
|
|
||||||
When using HTTP/1.1 the response line includes an explicit version, and the value of this key could feasibly be one of `b"HTTP/0.9"`, `b"HTTP/1.0"`, or `b"HTTP/1.1"`.
|
|
||||||
|
|
||||||
When using HTTP/2 there is no further response versioning included in the protocol, and the value of this key will always be `b"HTTP/2"`.
|
|
||||||
|
|
||||||
### `"reason_phrase"`
|
|
||||||
|
|
||||||
The reason-phrase of the HTTP response, as bytes. For example `b"OK"`. Some servers may include a custom reason phrase, although this is not recommended.
|
|
||||||
|
|
||||||
HTTP/2 onwards does not include a reason phrase on the wire.
|
|
||||||
|
|
||||||
When no key is included, a default based on the status code may be used.
|
|
||||||
|
|
||||||
### `"stream_id"`
|
|
||||||
|
|
||||||
When HTTP/2 is being used the `"stream_id"` response extension can be accessed to determine the ID of the data stream that the response was sent on.
|
|
||||||
|
|
||||||
### `"network_stream"`
|
|
||||||
|
|
||||||
The `"network_stream"` extension allows developers to handle HTTP `CONNECT` and `Upgrade` requests, by providing an API that steps outside the standard request/response model, and can directly read or write to the network.
|
|
||||||
|
|
||||||
The interface provided by the network stream:
|
|
||||||
|
|
||||||
* `read(max_bytes, timeout = None) -> bytes`
|
|
||||||
* `write(buffer, timeout = None)`
|
|
||||||
* `close()`
|
|
||||||
* `start_tls(ssl_context, server_hostname = None, timeout = None) -> NetworkStream`
|
|
||||||
* `get_extra_info(info) -> Any`
|
|
||||||
|
|
||||||
This API can be used as the foundation for working with HTTP proxies, WebSocket upgrades, and other advanced use-cases.
|
|
||||||
|
|
||||||
See the [network backends documentation](https://www.encode.io/httpcore/network-backends/) for more information on working directly with network streams.
|
|
||||||
|
|
||||||
**Extra network information**
|
|
||||||
|
|
||||||
The network stream abstraction also allows access to various low-level information that may be exposed by the underlying socket:
|
|
||||||
|
|
||||||
```python
|
|
||||||
response = httpx.get("https://www.example.com")
|
|
||||||
network_stream = response.extensions["network_stream"]
|
|
||||||
|
|
||||||
client_addr = network_stream.get_extra_info("client_addr")
|
|
||||||
server_addr = network_stream.get_extra_info("server_addr")
|
|
||||||
print("Client address", client_addr)
|
|
||||||
print("Server address", server_addr)
|
|
||||||
```
|
|
||||||
|
|
||||||
The socket SSL information is also available through this interface, although you need to ensure that the underlying connection is still open, in order to access it...
|
|
||||||
|
|
||||||
```python
|
|
||||||
with httpx.stream("GET", "https://www.example.com") as response:
|
|
||||||
network_stream = response.extensions["network_stream"]
|
|
||||||
|
|
||||||
ssl_object = network_stream.get_extra_info("ssl_object")
|
|
||||||
print("TLS version", ssl_object.version())
|
|
||||||
```

HTTPX supports setting up [HTTP proxies](https://en.wikipedia.org/wiki/Proxy_server#Web_proxy_servers) via the `proxy` parameter to be passed on client initialization or top-level API functions like `httpx.get(..., proxy=...)`.

</div>
|
|
||||||
|
|
||||||
## HTTP Proxies
|
|
||||||
|
|
||||||
To route all traffic (HTTP and HTTPS) to a proxy located at `http://localhost:8030`, pass the proxy URL to the client...
|
|
||||||
|
|
||||||
```python
|
|
||||||
with httpx.Client(proxy="http://localhost:8030") as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
For more advanced use cases, pass a mounts `dict`. For example, to route HTTP and HTTPS requests to 2 different proxies, respectively located at `http://localhost:8030`, and `http://localhost:8031`, pass a `dict` of proxy URLs:
|
|
||||||
|
|
||||||
```python
|
|
||||||
proxy_mounts = {
|
|
||||||
"http://": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
"https://": httpx.HTTPTransport(proxy="http://localhost:8031"),
|
|
||||||
}
|
|
||||||
|
|
||||||
with httpx.Client(mounts=proxy_mounts) as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
For detailed information about proxy routing, see the [Routing](#routing) section.
|
|
||||||
|
|
||||||
!!! tip "Gotcha"
|
|
||||||
In most cases, the proxy URL for the `https://` key _should_ use the `http://` scheme (that's not a typo!).
|
|
||||||
|
|
||||||
This is because HTTP proxying requires initiating a connection with the proxy server. While it's possible that your proxy supports doing it via HTTPS, most proxies only support doing it via HTTP.
|
|
||||||
|
|
||||||
For more information, see [FORWARD vs TUNNEL](#forward-vs-tunnel).
|
|
||||||
|
|
||||||
## Authentication
|
|
||||||
|
|
||||||
Proxy credentials can be passed as the `userinfo` section of the proxy URL. For example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
with httpx.Client(proxy="http://username:password@localhost:8030") as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
## Proxy mechanisms
|
|
||||||
|
|
||||||
!!! note
|
|
||||||
This section describes **advanced** proxy concepts and functionality.
|
|
||||||
|
|
||||||
### FORWARD vs TUNNEL
|
|
||||||
|
|
||||||
In general, the flow for making an HTTP request through a proxy is as follows:
|
|
||||||
|
|
||||||
1. The client connects to the proxy (initial connection request).
|
|
||||||
2. The proxy transfers data to the server on your behalf.
|
|
||||||
|
|
||||||
How exactly step 2/ is performed depends on which of two proxying mechanisms is used:
|
|
||||||
|
|
||||||
* **Forwarding**: the proxy makes the request for you, and sends back the response it obtained from the server.
|
|
||||||
* **Tunnelling**: the proxy establishes a TCP connection to the server on your behalf, and the client reuses this connection to send the request and receive the response. This is known as an [HTTP Tunnel](https://en.wikipedia.org/wiki/HTTP_tunnel). This mechanism is how you can access websites that use HTTPS from an HTTP proxy (the client "upgrades" the connection to HTTPS by performing the TLS handshake with the server over the TCP connection provided by the proxy).
|
|
||||||
|
|
||||||
### Troubleshooting proxies
|
|
||||||
|
|
||||||
If you encounter issues when setting up proxies, please refer to our [Troubleshooting guide](../troubleshooting.md#proxies).
|
|
||||||
|
|
||||||
## SOCKS
|
|
||||||
|
|
||||||
In addition to HTTP proxies, `httpcore` also supports proxies using the SOCKS protocol.
|
|
||||||
This is an optional feature that requires an additional third-party library be installed before use.
|
|
||||||
|
|
||||||
You can install SOCKS support using `pip`:
|
|
||||||
|
|
||||||
```shell
|

$ pip install httpx[socks]

```
|

You can now configure a client to make requests via a proxy using the SOCKS protocol:

|
|
||||||
```python
|

httpx.Client(proxy='socks5://user:pass@host:port')

You can control the connection pool size using the `limits` keyword
|

argument on the client. It takes instances of `httpx.Limits` which define:
|
|

- `max_keepalive_connections`, number of allowable keep-alive connections, or `None` to always

When making a request over HTTPS, HTTPX needs to verify the identity of the requested host. To do this, it uses a bundle of SSL certificates (a.k.a. CA bundle) delivered by a trusted certificate authority (CA).
|
|
||||||
|
|
||||||
### Enabling and disabling verification
|
|
||||||
|
|
||||||
By default httpx will verify HTTPS connections, and raise an error for invalid SSL cases...
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> httpx.get("https://expired.badssl.com/")
|
|
||||||
httpx.ConnectError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: certificate has expired (_ssl.c:997)
|
|
||||||
```
|
|
||||||
|
|
||||||
You can disable SSL verification completely and allow insecure requests...
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> httpx.get("https://expired.badssl.com/", verify=False)
|
|
||||||
<Response [200 OK]>
|
|
||||||
```
|
|
||||||
|
|
||||||
### Configuring client instances
|
|
||||||
|
|
||||||
If you're using a `Client()` instance you should pass any `verify=<...>` configuration when instantiating the client.
|
|
||||||
|
|
||||||
By default the [certifi CA bundle](https://certifiio.readthedocs.io/en/latest/) is used for SSL verification.
|
|
||||||
|
|
||||||
For more complex configurations you can pass an [SSL Context](https://docs.python.org/3/library/ssl.html) instance...
|
|
||||||
|
|
||||||
```python
|
|
||||||
import certifi
|
|
||||||
import httpx
|
|
||||||
import ssl
|
|
||||||
|
|
||||||
# This SSL context is equivalent to the default `verify=True`.
|
|
||||||
ctx = ssl.create_default_context(cafile=certifi.where())
|
|
||||||
client = httpx.Client(verify=ctx)
|
|
||||||
```
|
|
||||||
|
|
||||||
Using [the `truststore` package](https://truststore.readthedocs.io/) to support system certificate stores...
|
|
||||||
|
|
||||||
```python
|
|
||||||
import ssl
|
|
||||||
import truststore
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
# Use system certificate stores.
|
|
||||||
ctx = truststore.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
|
|
||||||
client = httpx.Client(verify=ctx)
|
|
||||||
```
|
|
||||||
|
|
||||||
Loding an alternative certificate verification store using [the standard SSL context API](https://docs.python.org/3/library/ssl.html)...
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
import ssl
|
|
||||||
|
|
||||||
# Use an explicitly configured certificate store.
|
|
||||||
ctx = ssl.create_default_context(cafile="path/to/certs.pem") # Either cafile or capath.
|
|
||||||
client = httpx.Client(verify=ctx)
|
|
||||||
```
|
|
||||||
|
|
||||||
### Client side certificates
|
|
||||||
|
|
||||||
Client side certificates allow a remote server to verify the client. They tend to be used within private organizations to authenticate requests to remote servers.
|
|
||||||
|
|
||||||
You can specify client-side certificates, using the [`.load_cert_chain()`](https://docs.python.org/3/library/ssl.html#ssl.SSLContext.load_cert_chain) API...
|
|
||||||
|
|
||||||
```python
|
|
||||||
ctx = ssl.create_default_context()
|
|
||||||
ctx.load_cert_chain(certfile="path/to/client.pem") # Optionally also keyfile or password.
|
|
||||||
client = httpx.Client(verify=ctx)
|
|
||||||
```
|
|
||||||
|
|
||||||
### Working with `SSL_CERT_FILE` and `SSL_CERT_DIR`
|
|
||||||
|
|
||||||
`httpx` does respect the `SSL_CERT_FILE` and `SSL_CERT_DIR` environment variables by default. For details, refer to [the section on the environment variables page](../environment_variables.md#ssl_cert_file).
|
|
||||||
|
|
||||||
### Making HTTPS requests to a local server
|
|
||||||
|
|
||||||
When making requests to local servers, such as a development server running on `localhost`, you will typically be using unencrypted HTTP connections.
|
|
||||||
|
|
||||||
If you do need to make HTTPS connections to a local server, for example to test an HTTPS-only service, you will need to create and use your own certificates. Here's one way to do it...
|
|
||||||
|
|
||||||
1. Use [trustme](https://github.com/python-trio/trustme) to generate a pair of server key/cert files, and a client cert file.
|
|
||||||
2. Pass the server key/cert files when starting your local server. (This depends on the particular web server you're using. For example, [Uvicorn](https://www.uvicorn.org) provides the `--ssl-keyfile` and `--ssl-certfile` options.)
|
|
||||||
3. Configure `httpx` to use the certificates stored in `client.pem`.
|
|
||||||
|
|
||||||
```python
|
|
||||||
ctx = ssl.create_default_context(cafile="client.pem")
|
|
||||||
client = httpx.Client(verify=ctx)
|
|
||||||
```

|

When accessing `response.text`, we need to decode the response bytes into a unicode text representation.
|
|
||||||
|
|
||||||
By default `httpx` will use `"charset"` information included in the response `Content-Type` header to determine how the response bytes should be decoded into text.
|
|
||||||
|
|
||||||
In cases where no charset information is included on the response, the default behaviour is to assume "utf-8" encoding, which is by far the most widely used text encoding on the internet.
|
|
||||||
|
|
||||||
## Using the default encoding
|
|
||||||
|
|
||||||
To understand this better let's start by looking at the default behaviour for text decoding...
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
# Instantiate a client with the default configuration.
|
|
||||||
client = httpx.Client()
|
|
||||||
# Using the client...
|
|
||||||
response = client.get(...)
|
|
||||||
print(response.encoding) # This will either print the charset given in
|
|
||||||
# the Content-Type charset, or else "utf-8".
|
|
||||||
print(response.text) # The text will either be decoded with the Content-Type
|
|
||||||
# charset, or using "utf-8".
|
|
||||||
```
|
|
||||||
|
|
||||||
This is normally absolutely fine. Most servers will respond with a properly formatted Content-Type header, including a charset encoding. And in most cases where no charset encoding is included, UTF-8 is very likely to be used, since it is so widely adopted.
|
|
||||||
|
|
||||||
## Using an explicit encoding
|
|
||||||
|
|
||||||
In some cases we might be making requests to a site where no character set information is being set explicitly by the server, but we know what the encoding is. In this case it's best to set the default encoding explicitly on the client.
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
# Instantiate a client with a Japanese character set as the default encoding.
|
|
||||||
client = httpx.Client(default_encoding="shift-jis")
|
|
||||||
# Using the client...
|
|
||||||
response = client.get(...)
|
|
||||||
print(response.encoding) # This will either print the charset given in
|
|
||||||
# the Content-Type charset, or else "shift-jis".
|
|
||||||
print(response.text) # The text will either be decoded with the Content-Type
|
|
||||||
# charset, or using "shift-jis".
|
|
||||||
```
|
|
||||||
|
|
||||||
## Using auto-detection
|
|
||||||
|
|
||||||
In cases where the server is not reliably including character set information, and where we don't know what encoding is being used, we can enable auto-detection to make a best-guess attempt when decoding from bytes to text.
|
|
||||||
|
|
||||||
To use auto-detection you need to set the `default_encoding` argument to a callable instead of a string. This callable should be a function which takes the input bytes as an argument and returns the character set to use for decoding those bytes to text.
|
|
||||||
|
|
||||||
There are two widely used Python packages which both handle this functionality:
|
|
||||||
|
|
||||||
* [`chardet`](https://chardet.readthedocs.io/) - This is a well established package, and is a port of [the auto-detection code in Mozilla](https://www-archive.mozilla.org/projects/intl/chardet.html).
|
|
||||||
* [`charset-normalizer`](https://charset-normalizer.readthedocs.io/) - A newer package, motivated by `chardet`, with a different approach.
|
|
||||||
|
|
||||||
Let's take a look at installing autodetection using one of these packages...
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ pip install httpx
|
|
||||||
$ pip install chardet
|
|
||||||
```
|
|
||||||
|
|
||||||
Once `chardet` is installed, we can configure a client to use character-set autodetection.
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
import chardet
|
|
||||||
|
|
||||||
def autodetect(content):
|
|
||||||
return chardet.detect(content).get("encoding")
|
|
||||||
|
|
||||||
# Using a client with character-set autodetection enabled.
|
|
||||||
client = httpx.Client(default_encoding=autodetect)
|
|
||||||
response = client.get(...)
|
|
||||||
print(response.encoding) # This will either print the charset given in
|
|
||||||
# the Content-Type charset, or else the auto-detected
|
|
||||||
# character set.
|
|
||||||
print(response.text)
|

||||||
```

HTTPX is careful to enforce timeouts everywhere by default.
|
|
||||||
|
|
||||||
The default behavior is to raise a `TimeoutException` after 5 seconds of
|
|
||||||
network inactivity.
|
|
||||||
|
|
||||||
## Setting and disabling timeouts
|
|
||||||
|
|
||||||
You can set timeouts for an individual request:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Using the top-level API:
|
|
||||||
httpx.get('http://example.com/api/v1/example', timeout=10.0)
|
|
||||||
|
|
||||||
# Using a client instance:
|
|
||||||
with httpx.Client() as client:
|
|
||||||
client.get("http://example.com/api/v1/example", timeout=10.0)
|
|
||||||
```
|
|
||||||
|
|
||||||
Or disable timeouts for an individual request:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Using the top-level API:
|
|
||||||
httpx.get('http://example.com/api/v1/example', timeout=None)
|
|
||||||
|
|
||||||
# Using a client instance:
|
|
||||||
with httpx.Client() as client:
|
|
||||||
client.get("http://example.com/api/v1/example", timeout=None)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Setting a default timeout on a client
|
|
||||||
|
|
||||||
You can set a timeout on a client instance, which results in the given
|
|
||||||
`timeout` being used as the default for requests made with this client:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client() # Use a default 5s timeout everywhere.
|
|
||||||
client = httpx.Client(timeout=10.0) # Use a default 10s timeout everywhere.
|
|
||||||
client = httpx.Client(timeout=None) # Disable all timeouts by default.
|
|
||||||
```
|
|
||||||
|
|
||||||
## Fine tuning the configuration
|
|
||||||
|
|
||||||
HTTPX also allows you to specify the timeout behavior in more fine grained detail.
|
|
||||||
|
|
||||||
There are four different types of timeouts that may occur. These are **connect**,
|
|
||||||
**read**, **write**, and **pool** timeouts.
|
|
||||||
|
|
||||||
* The **connect** timeout specifies the maximum amount of time to wait until
|
|
||||||
a socket connection to the requested host is established. If HTTPX is unable to connect
|
|
||||||
within this time frame, a `ConnectTimeout` exception is raised.
|
|
||||||
* The **read** timeout specifies the maximum duration to wait for a chunk of
|
|
||||||
data to be received (for example, a chunk of the response body). If HTTPX is
|
|
||||||
unable to receive data within this time frame, a `ReadTimeout` exception is raised.
|
|
||||||
* The **write** timeout specifies the maximum duration to wait for a chunk of
|
|
||||||
data to be sent (for example, a chunk of the request body). If HTTPX is unable
|
|
||||||
to send data within this time frame, a `WriteTimeout` exception is raised.
|
|
||||||
* The **pool** timeout specifies the maximum duration to wait for acquiring
|
|
||||||
a connection from the connection pool. If HTTPX is unable to acquire a connection
|
|
||||||
within this time frame, a `PoolTimeout` exception is raised. A related
|
|
||||||
configuration here is the maximum number of allowable connections in the
|
|
||||||
connection pool, which is configured by the `limits` argument.
|
|
||||||
|
|
||||||
You can configure the timeout behavior for any of these values...
|
|
||||||
|
|
||||||
```python
|
|
||||||
# A client with a 60s timeout for connecting, and a 10s timeout elsewhere.
|
|
||||||
timeout = httpx.Timeout(10.0, connect=60.0)
|
|
||||||
client = httpx.Client(timeout=timeout)
|
|
||||||
|
|
||||||
response = client.get('http://example.com/')
|
|
||||||
```

||||||

|
|||||||
HTTPX's `Client` also accepts a `transport` argument. This argument allows you
|
|
||||||
to provide a custom Transport object that will be used to perform the actual
|
|
||||||
sending of the requests.
|
|
||||||
|
|
||||||
## HTTP Transport
|
|
||||||
|
|
||||||
For some advanced configuration you might need to instantiate a transport
|
|
||||||
class directly, and pass it to the client instance. One example is the
|
|
||||||
`local_address` configuration which is only available via this low-level API.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> import httpx
|
|
||||||
>>> transport = httpx.HTTPTransport(local_address="0.0.0.0")
|
|
||||||
>>> client = httpx.Client(transport=transport)
|
|
||||||
```
|
|
||||||
|
|
||||||
Connection retries are also available via this interface. Requests will be retried the given number of times in case an `httpx.ConnectError` or an `httpx.ConnectTimeout` occurs, allowing smoother operation under flaky networks. If you need other forms of retry behaviors, such as handling read/write errors or reacting to `503 Service Unavailable`, consider general-purpose tools such as [tenacity](https://github.com/jd/tenacity).
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> import httpx
|
|
||||||
>>> transport = httpx.HTTPTransport(retries=1)
|
|
||||||
>>> client = httpx.Client(transport=transport)
|
|
||||||
```
|
|
||||||
|
|
||||||
Similarly, instantiating a transport directly provides a `uds` option for
|
|
||||||
connecting via a Unix Domain Socket that is only available via this low-level API:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> import httpx
|
|
||||||
>>> # Connect to the Docker API via a Unix Socket.
|
|
||||||
>>> transport = httpx.HTTPTransport(uds="/var/run/docker.sock")
|
|
||||||
>>> client = httpx.Client(transport=transport)
|
|
||||||
>>> response = client.get("http://docker/info")
|
|
||||||
>>> response.json()
|
|
||||||
{"ID": "...", "Containers": 4, "Images": 74, ...}
|
|
||||||
```
|
|
||||||
|
|
||||||
## WSGI Transport
|
|
||||||
|
|
||||||
You can configure an `httpx` client to call directly into a Python web application using the WSGI protocol.
|
|
||||||
|
|
||||||
This is particularly useful for two main use-cases:
|
|
||||||
|
|
||||||
* Using `httpx` as a client inside test cases.
|
|
||||||
* Mocking out external services during tests or in dev or staging environments.
|
|
||||||
|
|
||||||
### Example
|
|
||||||
|
|
||||||
Here's an example of integrating against a Flask application:
|
|
||||||
|
|
||||||
```python
|
|
||||||
from flask import Flask
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
|
|
||||||
app = Flask(__name__)
|
|
||||||
|
|
||||||
@app.route("/")
|
|
||||||
def hello():
|
|
||||||
return "Hello World!"
|
|
||||||
|
|
||||||
transport = httpx.WSGITransport(app=app)
|
|
||||||
with httpx.Client(transport=transport, base_url="http://testserver") as client:
|
|
||||||
r = client.get("/")
|
|
||||||
assert r.status_code == 200
|
|
||||||
assert r.text == "Hello World!"
|
|
||||||
```
|
|
||||||
|
|
||||||
### Configuration
|
|
||||||
|
|
||||||
For some more complex cases you might need to customize the WSGI transport. This allows you to:
|
|
||||||
|
|
||||||
* Inspect 500 error responses rather than raise exceptions by setting `raise_app_exceptions=False`.
|
|
||||||
* Mount the WSGI application at a subpath by setting `script_name` (WSGI).
|
|
||||||
* Use a given client address for requests by setting `remote_addr` (WSGI).
|
|
||||||
|
|
||||||
For example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Instantiate a client that makes WSGI requests with a client IP of "1.2.3.4".
|
|
||||||
transport = httpx.WSGITransport(app=app, remote_addr="1.2.3.4")
|
|
||||||
with httpx.Client(transport=transport, base_url="http://testserver") as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
## ASGI Transport
|
|
||||||
|
|
||||||
You can configure an `httpx` client to call directly into an async Python web application using the ASGI protocol.
|
|
||||||
|
|
||||||
This is particularly useful for two main use-cases:
|
|
||||||
|
|
||||||
* Using `httpx` as a client inside test cases.
|
|
||||||
* Mocking out external services during tests or in dev or staging environments.
|
|
||||||
|
|
||||||
### Example
|
|
||||||
|
|
||||||
Let's take this Starlette application as an example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
from starlette.applications import Starlette
|
|
||||||
from starlette.responses import HTMLResponse
|
|
||||||
from starlette.routing import Route
|
|
||||||
|
|
||||||
|
|
||||||
async def hello(request):
|
|
||||||
return HTMLResponse("Hello World!")
|
|
||||||
|
|
||||||
|
|
||||||
app = Starlette(routes=[Route("/", hello)])
|
|
||||||
```
|
|
||||||
|
|
||||||
We can make requests directly against the application, like so:
|
|
||||||
|
|
||||||
```python
|
|
||||||
transport = httpx.ASGITransport(app=app)
|
|
||||||
|
|
||||||
async with httpx.AsyncClient(transport=transport, base_url="http://testserver") as client:
|
|
||||||
r = await client.get("/")
|
|
||||||
assert r.status_code == 200
|
|
||||||
assert r.text == "Hello World!"
|
|
||||||
```
|
|
||||||
|
|
||||||
### Configuration
|
|
||||||
|
|
||||||
For some more complex cases you might need to customise the ASGI transport. This allows you to:
|
|
||||||
|
|
||||||
* Inspect 500 error responses rather than raise exceptions by setting `raise_app_exceptions=False`.
|
|
||||||
* Mount the ASGI application at a subpath by setting `root_path`.
|
|
||||||
* Use a given client address for requests by setting `client`.
|
|
||||||
|
|
||||||
For example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Instantiate a client that makes ASGI requests with a client IP of "1.2.3.4",
|
|
||||||
# on port 123.
|
|
||||||
transport = httpx.ASGITransport(app=app, client=("1.2.3.4", 123))
|
|
||||||
async with httpx.AsyncClient(transport=transport, base_url="http://testserver") as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
See [the ASGI documentation](https://asgi.readthedocs.io/en/latest/specs/www.html#connection-scope) for more details on the `client` and `root_path` keys.
|
|
||||||
|
|
||||||
### ASGI startup and shutdown
|
|
||||||
|
|
||||||
It is not in the scope of HTTPX to trigger ASGI lifespan events of your app.
|
|
||||||
|
|
||||||
However it is suggested to use `LifespanManager` from [asgi-lifespan](https://github.com/florimondmanca/asgi-lifespan#usage) in pair with `AsyncClient`.
|
|
||||||
|
|
||||||
## Custom transports
|
|
||||||
|
|
||||||
A transport instance must implement the low-level Transport API which deals
|
|
||||||
with sending a single request, and returning a response. You should either
|
|
||||||
subclass `httpx.BaseTransport` to implement a transport to use with `Client`,
|
|
||||||
or subclass `httpx.AsyncBaseTransport` to implement a transport to
|
|
||||||
use with `AsyncClient`.
|
|
||||||
|
|
||||||
At the layer of the transport API we're using the familiar `Request` and
|
|
||||||
`Response` models.
|
|
||||||
|
|
||||||
See the `handle_request` and `handle_async_request` docstrings for more details
|
|
||||||
on the specifics of the Transport API.
|
|
||||||
|
|
||||||
A complete example of a custom transport implementation would be:
|
|
||||||
|
|
||||||
```python
|
|
||||||
import json
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
class HelloWorldTransport(httpx.BaseTransport):
|
|
||||||
"""
|
|
||||||
A mock transport that always returns a JSON "Hello, world!" response.
|
|
||||||
"""
|
|
||||||
|
|
||||||
def handle_request(self, request):
|
|
||||||
return httpx.Response(200, json={"text": "Hello, world!"})
|
|
||||||
```
|
|
||||||
|
|
||||||
Or this example, which uses a custom transport and `httpx.Mounts` to always redirect `http://` requests.
|
|
||||||
|
|
||||||
```python
|
|
||||||
class HTTPSRedirect(httpx.BaseTransport):
|
|
||||||
"""
|
|
||||||
A transport that always redirects to HTTPS.
|
|
||||||
"""
|
|
||||||
def handle_request(self, request):
|
|
||||||
url = request.url.copy_with(scheme="https")
|
|
||||||
return httpx.Response(303, headers={"Location": str(url)})
|
|
||||||
|
|
||||||
# A client where any `http` requests are always redirected to `https`
|
|
||||||
transport = httpx.Mounts({
|
|
||||||
'http://': HTTPSRedirect()
|
|
||||||
'https://': httpx.HTTPTransport()
|
|
||||||
})
|
|
||||||
client = httpx.Client(transport=transport)
|
|
||||||
```
|
|
||||||
|
|
||||||
A useful pattern here is custom transport classes that wrap the default HTTP implementation. For example...
|
|
||||||
|
|
||||||
```python
|
|
||||||
class DebuggingTransport(httpx.BaseTransport):
|
|
||||||
def __init__(self, **kwargs):
|
|
||||||
self._wrapper = httpx.HTTPTransport(**kwargs)
|
|
||||||
|
|
||||||
def handle_request(self, request):
|
|
||||||
print(f">>> {request}")
|
|
||||||
response = self._wrapper.handle_request(request)
|
|
||||||
print(f"<<< {response}")
|
|
||||||
return response
|
|
||||||
|
|
||||||
def close(self):
|
|
||||||
self._wrapper.close()
|
|
||||||
|
|
||||||
transport = DebuggingTransport()
|
|
||||||
client = httpx.Client(transport=transport)
|
|
||||||
```
|
|
||||||
|
|
||||||
Here's another case, where we're using a round-robin across a number of different proxies...
|
|
||||||
|
|
||||||
```python
|
|
||||||
class ProxyRoundRobin(httpx.BaseTransport):
|
|
||||||
def __init__(self, proxies, **kwargs):
|
|
||||||
self._transports = [
|
|
||||||
httpx.HTTPTransport(proxy=proxy, **kwargs)
|
|
||||||
for proxy in proxies
|
|
||||||
]
|
|
||||||
self._idx = 0
|
|
||||||
|
|
||||||
def handle_request(self, request):
|
|
||||||
transport = self._transports[self._idx]
|
|
||||||
self._idx = (self._idx + 1) % len(self._transports)
|
|
||||||
return transport.handle_request(request)
|
|
||||||
|
|
||||||
def close(self):
|
|
||||||
for transport in self._transports:
|
|
||||||
transport.close()
|
|
||||||
|
|
||||||
proxies = [
|
|
||||||
httpx.Proxy("http://127.0.0.1:8081"),
|
|
||||||
httpx.Proxy("http://127.0.0.1:8082"),
|
|
||||||
httpx.Proxy("http://127.0.0.1:8083"),
|
|
||||||
]
|
|
||||||
transport = ProxyRoundRobin(proxies=proxies)
|
|
||||||
client = httpx.Client(transport=transport)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Mock transports
|
|
||||||
|
|
||||||
During testing it can often be useful to be able to mock out a transport,
|
|
||||||
and return pre-determined responses, rather than making actual network requests.
|
|
||||||
|
|
||||||
The `httpx.MockTransport` class accepts a handler function, which can be used
|
|
||||||
to map requests onto pre-determined responses:
|
|
||||||
|
|
||||||
```python
|
|
||||||
def handler(request):
|
|
||||||
return httpx.Response(200, json={"text": "Hello, world!"})
|
|
||||||
|
|
||||||
|
|
||||||
# Switch to a mock transport, if the TESTING environment variable is set.
|
|
||||||
if os.environ.get('TESTING', '').upper() == "TRUE":
|
|
||||||
transport = httpx.MockTransport(handler)
|
|
||||||
else:
|
|
||||||
transport = httpx.HTTPTransport()
|
|
||||||
|
|
||||||
client = httpx.Client(transport=transport)
|
|
||||||
```
|
|
||||||
|
|
||||||
For more advanced use-cases you might want to take a look at either [the third-party
|
|
||||||
mocking library, RESPX](https://lundberg.github.io/respx/), or the [pytest-httpx library](https://github.com/Colin-b/pytest_httpx).
|
|
||||||
|
|
||||||
## Mounting transports
|
|
||||||
|
|
||||||
You can also mount transports against given schemes or domains, to control
|
|
||||||
which transport an outgoing request should be routed via, with [the same style
|
|
||||||
used for specifying proxy routing](#routing).
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
class HTTPSRedirectTransport(httpx.BaseTransport):
|
|
||||||
"""
|
|
||||||
A transport that always redirects to HTTPS.
|
|
||||||
"""
|
|
||||||
|
|
||||||
def handle_request(self, method, url, headers, stream, extensions):
|
|
||||||
scheme, host, port, path = url
|
|
||||||
if port is None:
|
|
||||||
location = b"https://%s%s" % (host, path)
|
|
||||||
else:
|
|
||||||
location = b"https://%s:%d%s" % (host, port, path)
|
|
||||||
stream = httpx.ByteStream(b"")
|
|
||||||
headers = [(b"location", location)]
|
|
||||||
extensions = {}
|
|
||||||
return 303, headers, stream, extensions
|
|
||||||
|
|
||||||
|
|
||||||
# A client where any `http` requests are always redirected to `https`
|
|
||||||
mounts = {'http://': HTTPSRedirectTransport()}
|
|
||||||
client = httpx.Client(mounts=mounts)
|
|
||||||
```
|
|
||||||
|
|
||||||
A couple of other sketches of how you might take advantage of mounted transports...
|
|
||||||
|
|
||||||
Disabling HTTP/2 on a single given domain...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"all://": httpx.HTTPTransport(http2=True),
|
|
||||||
"all://*example.org": httpx.HTTPTransport()
|
|
||||||
}
|
|
||||||
client = httpx.Client(mounts=mounts)
|
|
||||||
```
|
|
||||||
|
|
||||||
Mocking requests to a given domain:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# All requests to "example.org" should be mocked out.
|
|
||||||
# Other requests occur as usual.
|
|
||||||
def handler(request):
|
|
||||||
return httpx.Response(200, json={"text": "Hello, World!"})
|
|
||||||
|
|
||||||
mounts = {"all://example.org": httpx.MockTransport(handler)}
|
|
||||||
client = httpx.Client(mounts=mounts)
|
|
||||||
```
|
|
||||||
|
|
||||||
Adding support for custom schemes:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Support URLs like "file:///Users/sylvia_green/websites/new_client/index.html"
|
|
||||||
mounts = {"file://": FileSystemTransport()}
|
|
||||||
client = httpx.Client(mounts=mounts)
|
|
||||||
```
|
|
||||||
|
|
||||||
### Routing
|
|
||||||
|
|
||||||
HTTPX provides a powerful mechanism for routing requests, allowing you to write complex rules that specify which transport should be used for each request.
|
|
||||||
|
|
||||||
The `mounts` dictionary maps URL patterns to HTTP transports. HTTPX matches requested URLs against URL patterns to decide which transport should be used, if any. Matching is done from most specific URL patterns (e.g. `https://<domain>:<port>`) to least specific ones (e.g. `https://`).
|
|
||||||
|
|
||||||
HTTPX supports routing requests based on **scheme**, **domain**, **port**, or a combination of these.
|
|
||||||
|
|
||||||
### Wildcard routing
|
|
||||||
|
|
||||||
Route everything through a transport...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"all://": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Scheme routing
|
|
||||||
|
|
||||||
Route HTTP requests through one transport, and HTTPS requests through another...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"http://": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
"https://": httpx.HTTPTransport(proxy="http://localhost:8031"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Domain routing
|
|
||||||
|
|
||||||
Proxy all requests on domain "example.com", let other requests pass through...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"all://example.com": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Proxy HTTP requests on domain "example.com", let HTTPS and other requests pass through...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"http://example.com": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Proxy all requests to "example.com" and its subdomains, let other requests pass through...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"all://*example.com": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Proxy all requests to strict subdomains of "example.com", let "example.com" and other requests pass through...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"all://*.example.com": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Port routing
|
|
||||||
|
|
||||||
Proxy HTTPS requests on port 1234 to "example.com"...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"https://example.com:1234": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Proxy all requests on port 1234...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"all://*:1234": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### No-proxy support
|
|
||||||
|
|
||||||
It is also possible to define requests that _shouldn't_ be routed through the transport.
|
|
||||||
|
|
||||||
To do so, pass `None` as the proxy URL. For example...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
# Route requests through a proxy by default...
|
|
||||||
"all://": httpx.HTTPTransport(proxy="http://localhost:8031"),
|
|
||||||
# Except those for "example.com".
|
|
||||||
"all://example.com": None,
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Complex configuration example
|
|
||||||
|
|
||||||
You can combine the routing features outlined above to build complex proxy routing configurations. For example...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
# Route all traffic through a proxy by default...
|
|
||||||
"all://": httpx.HTTPTransport(proxy="http://localhost:8030"),
|
|
||||||
# But don't use proxies for HTTPS requests to "domain.io"...
|
|
||||||
"https://domain.io": None,
|
|
||||||
# And use another proxy for requests to "example.com" and its subdomains...
|
|
||||||
"all://*example.com": httpx.HTTPTransport(proxy="http://localhost:8031"),
|
|
||||||
# And yet another proxy if HTTP is used,
|
|
||||||
# and the "internal" subdomain on port 5550 is requested...
|
|
||||||
"http://internal.example.com:5550": httpx.HTTPTransport(proxy="http://localhost:8032"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
### Environment variables
|
|
||||||
|
|
||||||
There are also environment variables that can be used to control the dictionary of the client mounts.
|
|
||||||
They can be used to configure HTTP proxying for clients.
|
|
||||||
|
|
||||||
See documentation on [`HTTP_PROXY`, `HTTPS_PROXY`, `ALL_PROXY`](../environment_variables.md#http_proxy-https_proxy-all_proxy)
|
|
||||||
and [`NO_PROXY`](../environment_variables.md#no_proxy) for more information.

!!! note
|

or making a small number of requests. Using a `Client` will
|
|
||||||
enable HTTP/2 and connection pooling for more efficient and

# Async Support
|
|
||||||
|
|
||||||
HTTPX offers a standard synchronous API by default, but also gives you
|
|
||||||
the option of an async client if you need it.
|
|
||||||
|
|
||||||
Async is a concurrency model that is far more efficient than multi-threading,
|
|
||||||
and can provide significant performance benefits and enable the use of
|
|
||||||
long-lived network connections such as WebSockets.
|
|
||||||
|
|
||||||
If you're working with an async web framework then you'll also want to use an
|
|
||||||
async client for sending outgoing HTTP requests.
|
|
||||||
|
|
||||||
## Making Async requests
|
|
||||||
|
|
||||||
To make asynchronous requests, you'll need an `AsyncClient`.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> async with httpx.AsyncClient() as client:
|
|
||||||
... r = await client.get('https://www.example.com/')
|
|
||||||
...
|
|
||||||
>>> r
|
|
||||||
<Response [200 OK]>
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! tip
|
|
||||||
Use [IPython](https://ipython.readthedocs.io/en/stable/) or Python 3.9+ with `python -m asyncio` to try this code interactively, as they support executing `async`/`await` expressions in the console.
|
|
||||||
|
|
||||||
## API Differences
|
|
||||||
|
|
||||||
If you're using an async client then there are a few bits of API that
|
|
||||||
use async methods.
|
|
||||||
|
|
||||||
### Making requests
|
|
||||||
|
|
||||||
The request methods are all async, so you should use `response = await client.get(...)` style for all of the following:
|
|
||||||
|
|
||||||
* `AsyncClient.get(url, ...)`
|
|
||||||
* `AsyncClient.options(url, ...)`
|
|
||||||
* `AsyncClient.head(url, ...)`
|
|
||||||
* `AsyncClient.post(url, ...)`
|
|
||||||
* `AsyncClient.put(url, ...)`
|
|
||||||
* `AsyncClient.patch(url, ...)`
|
|
||||||
* `AsyncClient.delete(url, ...)`
|
|
||||||
* `AsyncClient.request(method, url, ...)`
|
|
||||||
* `AsyncClient.send(request, ...)`
|
|
||||||
|
|
||||||
### Opening and closing clients
|
|
||||||
|
|
||||||
Use `async with httpx.AsyncClient()` if you want a context-managed client...
|
|
||||||
|
|
||||||
```python
|
|
||||||
async with httpx.AsyncClient() as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! warning
|
|
||||||
In order to get the most benefit from connection pooling, make sure you're not instantiating multiple client instances - for example by using `async with` inside a "hot loop". This can be achieved either by having a single scoped client that's passed throughout wherever it's needed, or by having a single global client instance.
|
|
||||||
|
|
||||||
Alternatively, use `await client.aclose()` if you want to close a client explicitly:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.AsyncClient()
|
|
||||||
...
|
|
||||||
await client.aclose()
|
|
||||||
```
|
|
||||||
|
|
||||||
### Streaming responses
|
|
||||||
|
|
||||||
The `AsyncClient.stream(method, url, ...)` method is an async context block.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> client = httpx.AsyncClient()
|
|
||||||
>>> async with client.stream('GET', 'https://www.example.com/') as response:
|
|
||||||
... async for chunk in response.aiter_bytes():
|
|
||||||
... ...
|
|
||||||
```
|
|
||||||
|
|
||||||
The async response streaming methods are:
|
|
||||||
|
|
||||||
* `Response.aread()` - For conditionally reading a response inside a stream block.
|
|
||||||
* `Response.aiter_bytes()` - For streaming the response content as bytes.
|
|
||||||
* `Response.aiter_text()` - For streaming the response content as text.
|
|
||||||
* `Response.aiter_lines()` - For streaming the response content as lines of text.
|
|
||||||
* `Response.aiter_raw()` - For streaming the raw response bytes, without applying content decoding.
|
|
||||||
* `Response.aclose()` - For closing the response. You don't usually need this, since `.stream` block closes the response automatically on exit.
|
|
||||||
|
|
||||||
For situations when context block usage is not practical, it is possible to enter "manual mode" by sending a [`Request` instance](advanced/clients.md#request-instances) using `client.send(..., stream=True)`.
|
|
||||||
|
|
||||||
Example in the context of forwarding the response to a streaming web endpoint with [Starlette](https://www.starlette.io):
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
from starlette.background import BackgroundTask
|
|
||||||
from starlette.responses import StreamingResponse
|
|
||||||
|
|
||||||
client = httpx.AsyncClient()
|
|
||||||
|
|
||||||
async def home(request):
|
|
||||||
req = client.build_request("GET", "https://www.example.com/")
|
|
||||||
r = await client.send(req, stream=True)
|
|
||||||
return StreamingResponse(r.aiter_text(), background=BackgroundTask(r.aclose))
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! warning
|
|
||||||
When using this "manual streaming mode", it is your duty as a developer to make sure that `Response.aclose()` is called eventually. Failing to do so would leave connections open, most likely resulting in resource leaks down the line.
|
|
||||||
|
|
||||||
### Streaming requests
|
|
||||||
|
|
||||||
When sending a streaming request body with an `AsyncClient` instance, you should use an async bytes generator instead of a bytes generator:
|
|
||||||
|
|
||||||
```python
|
|
||||||
async def upload_bytes():
|
|
||||||
... # yield byte content
|
|
||||||
|
|
||||||
await client.post(url, content=upload_bytes())
|
|
||||||
```
|
|
||||||
|
|
||||||
### Explicit transport instances
|
|
||||||
|
|
||||||
When instantiating a transport instance directly, you need to use `httpx.AsyncHTTPTransport`.
|
|
||||||
|
|
||||||
For instance:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> import httpx
|
|
||||||
>>> transport = httpx.AsyncHTTPTransport(retries=1)
|
|
||||||
>>> async with httpx.AsyncClient(transport=transport) as client:
|
|
||||||
>>> ...
|
|
||||||
```
|
|
||||||
|
|
||||||
## Supported async environments
|
|
||||||
|
|
||||||
HTTPX supports either `asyncio` or `trio` as an async environment.
|
|
||||||
|
|
||||||
It will auto-detect which of those two to use as the backend
|
|
||||||
for socket operations and concurrency primitives.
|
|
||||||
|
|
||||||
### [AsyncIO](https://docs.python.org/3/library/asyncio.html)
|
|
||||||
|
|
||||||
AsyncIO is Python's [built-in library](https://docs.python.org/3/library/asyncio.html)
|
|
||||||
for writing concurrent code with the async/await syntax.
|
|
||||||
|
|
||||||
```python
|
|
||||||
import asyncio
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
async def main():
|
|
||||||
async with httpx.AsyncClient() as client:
|
|
||||||
response = await client.get('https://www.example.com/')
|
|
||||||
print(response)
|
|
||||||
|
|
||||||
asyncio.run(main())
|
|
||||||
```
|
|
||||||
|
|
||||||
### [Trio](https://github.com/python-trio/trio)
|
|
||||||
|
|
||||||
Trio is [an alternative async library](https://trio.readthedocs.io/en/stable/),
|
|
||||||
designed around the [the principles of structured concurrency](https://en.wikipedia.org/wiki/Structured_concurrency).
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
import trio
|
|
||||||
|
|
||||||
async def main():
|
|
||||||
async with httpx.AsyncClient() as client:
|
|
||||||
response = await client.get('https://www.example.com/')
|
|
||||||
print(response)
|
|
||||||
|
|
||||||
trio.run(main)
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! important
|
|
||||||
The `trio` package must be installed to use the Trio backend.
|
|
||||||
|
|
||||||
|
|
||||||
### [AnyIO](https://github.com/agronholm/anyio)
|
|
||||||
|
|
||||||
AnyIO is an [asynchronous networking and concurrency library](https://anyio.readthedocs.io/) that works on top of either `asyncio` or `trio`. It blends in with native libraries of your chosen backend (defaults to `asyncio`).
|
|
||||||
|
|
||||||
```python
|
|
||||||
import httpx
|
|
||||||
import anyio
|
|
||||||
|
|
||||||
async def main():
|
|
||||||
async with httpx.AsyncClient() as client:
|
|
||||||
response = await client.get('https://www.example.com/')
|
|
||||||
print(response)
|
|
||||||
|
|
||||||
anyio.run(main, backend='trio')
|
|
||||||
```
|
|
||||||
|
|
||||||

# Clients
|
||||||
|
|
||||||
|
HTTP requests are sent by using a `Client` instance. Client instances are thread safe interfaces that maintain a pool of HTTP connections.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> cli = httpx.Client()
|
||||||
|
>>> cli
|
||||||
|
<Client [0 active]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> cli = ahttpx.Client()
|
||||||
|
>>> cli
|
||||||
|
<Client [0 active]>
|
||||||
|
```
|
||||||
|
|
||||||
|
The client representation provides an indication of how many connections are currently in the pool.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> r = cli.get("https://www.example.com")
|
||||||
|
>>> r = cli.get("https://www.wikipedia.com")
|
||||||
|
>>> r = cli.get("https://www.theguardian.com/uk")
|
||||||
|
>>> cli
|
||||||
|
<Client [0 active, 3 idle]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> r = await cli.get("https://www.example.com")
|
||||||
|
>>> r = await cli.get("https://www.wikipedia.com")
|
||||||
|
>>> r = await cli.get("https://www.theguardian.com/uk")
|
||||||
|
>>> cli
|
||||||
|
<Client [0 active, 3 idle]>
|
||||||
|
```
|
||||||
|
|
||||||
|
The connections in the pool can be explicitly closed, using the `close()` method...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> cli.close()
|
||||||
|
>>> cli
|
||||||
|
<Client [0 active]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> await cli.close()
|
||||||
|
>>> cli
|
||||||
|
<Client [0 active]>
|
||||||
|
```
|
||||||
|
|
||||||
|
Client instances support being used in a context managed scope. You can use this style to enforce properly scoped resources, ensuring that the connection pool is cleanly closed when no longer required.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> with httpx.Client() as cli:
|
||||||
|
... r = cli.get("https://www.example.com")
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> async with ahttpx.Client() as cli:
|
||||||
|
... r = await cli.get("https://www.example.com")
|
||||||
|
```
|
||||||
|
|
||||||
|
It is important to scope the use of client instances as widely as possible.
|
||||||
|
|
||||||
|
Typically you should have a single client instance that is used throughout the lifespan of your application. This ensures that connection pooling is maximised, and minmises unneccessary reloading of SSL certificate stores.
|
||||||
|
|
||||||
|
The recommened usage is to *either* a have single global instance created at import time, *or* a single context scoped instance that is passed around wherever it is required.
|
||||||
|
|
||||||
|
## Setting a base URL
|
||||||
|
|
||||||
|
Client instances can be configured with a base URL that is used when constructing requests...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> with httpx.Client(url="https://www.httpbin.org") as cli:
|
||||||
|
>>> r = cli.get("/json")
|
||||||
|
>>> print(r)
|
||||||
|
<Response [200 OK]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> async with ahttpx.Client(url="https://www.httpbin.org") as cli:
|
||||||
|
>>> r = cli.get("/json")
|
||||||
|
>>> print(r)
|
||||||
|
<Response [200 OK]>
|
||||||
|
```
|
||||||
|
|
||||||
|
## Setting client headers
|
||||||
|
|
||||||
|
Client instances include a set of headers that are used on every outgoing request.
|
||||||
|
|
||||||
|
The default headers are:
|
||||||
|
|
||||||
|
* `Accept: */*` - Indicates to servers that any media type may be returned.
|
||||||
|
* `Accept-Encoding: gzip` - Indicates to servers that gzip compression may be used on responses.
|
||||||
|
* `Connection: keep-alive` - Indicates that HTTP/1.1 connections should be reused over multiple requests.
|
||||||
|
* `User-Agent: python-httpx/1.0` - Identify the client as `httpx`.
|
||||||
|
|
||||||
|
You can override this behavior by explicitly specifying the default headers...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> headers = {"User-Agent": "dev", "Accept-Encoding": "gzip"}
|
||||||
|
>>> with httpx.Client(headers=headers) as cli:
|
||||||
|
>>> r = cli.get("https://www.example.com/")
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> headers = {"User-Agent": "dev", "Accept-Encoding": "gzip"}
|
||||||
|
>>> async with ahttpx.Client(headers=headers) as cli:
|
||||||
|
>>> r = await cli.get("https://www.example.com/")
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuring the connection pool
|
||||||
|
|
||||||
|
The connection pool used by the client can be configured in order to customise the SSL context, the maximum number of concurrent connections, or the network backend.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> # Setup an SSL context to allow connecting to improperly configured SSL.
|
||||||
|
>>> no_verify = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
|
||||||
|
>>> no_verify.check_hostname = False
|
||||||
|
>>> no_verify.verify_mode = ssl.CERT_NONE
|
||||||
|
>>> # Instantiate a client with our custom SSL context.
|
||||||
|
>>> pool = httpx.ConnectionPool(ssl_context=no_verify)
|
||||||
|
>>> with httpx.Client(transport=pool) as cli:
|
||||||
|
>>> ...
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> # Setup an SSL context to allow connecting to improperly configured SSL.
|
||||||
|
>>> no_verify = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
|
||||||
|
>>> no_verify.check_hostname = False
|
||||||
|
>>> no_verify.verify_mode = ssl.CERT_NONE
|
||||||
|
>>> # Instantiate a client with our custom SSL context.
|
||||||
|
>>> pool = ahttpx.ConnectionPool(ssl_context=no_verify)
|
||||||
|
>>> async with ahttpx.Client(transport=pool) as cli:
|
||||||
|
>>> ...
|
||||||
|
```
|
||||||
|
|
||||||
|
## Sending requests
|
||||||
|
|
||||||
|
* `.request()` - Send an HTTP request, reading the response to completion.
|
||||||
|
* `.stream()` - Send an HTTP request, streaming the response.
|
||||||
|
|
||||||
|
Shortcut methods...
|
||||||
|
|
||||||
|
* `.get()` - Send an HTTP `GET` request.
|
||||||
|
* `.post()` - Send an HTTP `POST` request.
|
||||||
|
* `.put()` - Send an HTTP `PUT` request.
|
||||||
|
* `.delete()` - Send an HTTP `DELETE` request.
|
||||||
|

|
||||||
|
|
||||||
|
## Transports
|
||||||
|
|
||||||
|
By default requests are sent using the `ConnectionPool` class. Alternative implementations for sending requests can be created by subclassing the `Transport` interface.
|
||||||
|
|
||||||
|
For example, a mock transport class that doesn't make any network requests and instead always returns a fixed response.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
class MockTransport(httpx.Transport):
|
||||||
|
def __init__(self, response):
|
||||||
|
self._response = response
|
||||||
|
|
||||||
|
@contextlib.contextmanager
|
||||||
|
def send(self, request):
|
||||||
|
yield response
|
||||||
|
|
||||||
|
def close(self):
|
||||||
|
pass
|
||||||
|
|
||||||
|
response = httpx.Response(200, content=httpx.Text('Hello, world'))
|
||||||
|
transport = MockTransport(response=response)
|
||||||
|
with httpx.Client(transport=transport) as cli:
|
||||||
|
r = cli.get('https://www.example.com')
|
||||||
|
print(r)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
class MockTransport(ahttpx.Transport):
|
||||||
|
def __init__(self, response):
|
||||||
|
self._response = response
|
||||||
|
|
||||||
|
@contextlib.contextmanager
|
||||||
|
def send(self, request):
|
||||||
|
yield response
|
||||||
|
|
||||||
|
def close(self):
|
||||||
|
pass
|
||||||
|
|
||||||
|
response = ahttpx.Response(200, content=httpx.Text('Hello, world'))
|
||||||
|
transport = MockTransport(response=response)
|
||||||
|
async with ahttpx.Client(transport=transport) as cli:
|
||||||
|
r = await cli.get('https://www.example.com')
|
||||||
|
print(r)
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Middleware
|
||||||
|
|
||||||
|
In addition to maintaining an HTTP connection pool, client instances are responsible for two other pieces of functionality...
|
||||||
|
|
||||||
|
* Dealing with HTTP redirects.
|
||||||
|
* Maintaining an HTTP cookie store.
|
||||||
|
|
||||||
|
### `RedirectMiddleware`
|
||||||
|
|
||||||
|
Wraps a transport class, adding support for HTTP redirect handling.
|
||||||
|
|
||||||
|
### `CookieMiddleware`
|
||||||
|
|
||||||
|
Wraps a transport class, adding support for HTTP cookie persistence.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Custom client implementations
|
||||||
|
|
||||||
|
The `Client` implementation in `httpx` is intentionally lightweight.
|
||||||
|
|
||||||
|
If you're working with a large codebase you might want to create a custom client implementation in order to constrain the types of request that are sent.
|
||||||
|
|
||||||
|
The following example demonstrates a custom API client that only exposes `GET` and `POST` requests, and always uses JSON payloads.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
class APIClient:
|
||||||
|
def __init__(self):
|
||||||
|
self.url = httpx.URL('https://www.example.com')
|
||||||
|
self.headers = httpx.Headers({
|
||||||
|
'Accept-Encoding': 'gzip',
|
||||||
|
'Connection': 'keep-alive',
|
||||||
|
'User-Agent': 'dev'
|
||||||
|
})
|
||||||
|
self.via = httpx.RedirectMiddleware(httpx.ConnectionPool())
|
||||||
|
|
||||||
|
def get(self, path: str) -> Response:
|
||||||
|
request = httpx.Request(
|
||||||
|
method="GET",
|
||||||
|
url=self.url.join(path),
|
||||||
|
headers=self.headers,
|
||||||
|
)
|
||||||
|
with self.via.send(request) as response:
|
||||||
|
response.read()
|
||||||
|
return response
|
||||||
|
|
||||||
|
def post(self, path: str, payload: Any) -> httpx.Response:
|
||||||
|
request = httpx.Request(
|
||||||
|
method="POST",
|
||||||
|
url=self.url.join(path),
|
||||||
|
headers=self.headers,
|
||||||
|
content=httpx.JSON(payload),
|
||||||
|
)
|
||||||
|
with self.via.send(request) as response:
|
||||||
|
response.read()
|
||||||
|
return response
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
class APIClient:
|
||||||
|
def __init__(self):
|
||||||
|
self.url = ahttpx.URL('https://www.example.com')
|
||||||
|
self.headers = ahttpx.Headers({
|
||||||
|
'Accept-Encoding': 'gzip',
|
||||||
|
'Connection': 'keep-alive',
|
||||||
|
'User-Agent': 'dev'
|
||||||
|
})
|
||||||
|
self.via = ahttpx.RedirectMiddleware(ahttpx.ConnectionPool())
|
||||||
|
|
||||||
|
async def get(self, path: str) -> Response:
|
||||||
|
request = ahttpx.Request(
|
||||||
|
method="GET",
|
||||||
|
url=self.url.join(path),
|
||||||
|
headers=self.headers,
|
||||||
|
)
|
||||||
|
async with self.via.send(request) as response:
|
||||||
|
await response.read()
|
||||||
|
return response
|
||||||
|
|
||||||
|
async def post(self, path: str, payload: Any) -> ahttpx.Response:
|
||||||
|
request = ahttpx.Request(
|
||||||
|
method="POST",
|
||||||
|
url=self.url.join(path),
|
||||||
|
headers=self.headers,
|
||||||
|
content=httpx.JSON(payload),
|
||||||
|
)
|
||||||
|
async with self.via.send(request) as response:
|
||||||
|
await response.read()
|
||||||
|
return response
|
||||||
|
```
|
||||||
|
|
||||||
|
You can expand on this pattern to provide behavior such as request or response schema validation, consistent timeouts, or standardised logging and exception handling.

# Requests Compatibility Guide
|
|
||||||
|
|
||||||
HTTPX aims to be broadly compatible with the `requests` API, although there are a
|
|
||||||
few design differences in places.
|
|
||||||
|
|
||||||
This documentation outlines places where the API differs...
|
|
||||||
|
|
||||||
## Redirects
|
|
||||||
|
|
||||||
Unlike `requests`, HTTPX does **not follow redirects by default**.
|
|
||||||
|
|
||||||
We differ in behaviour here [because auto-redirects can easily mask unnecessary network
|
|
||||||
calls being made](https://github.com/encode/httpx/discussions/1785).
|
|
||||||
|
|
||||||
You can still enable behaviour to automatically follow redirects, but you need to
|
|
||||||
do so explicitly...
|
|
||||||
|
|
||||||
```python
|
|
||||||
response = client.get(url, follow_redirects=True)
|
|
||||||
```
|
|
||||||
|
|
||||||
Or else instantiate a client, with redirect following enabled by default...
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client(follow_redirects=True)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Client instances
|
|
||||||
|
|
||||||
The HTTPX equivalent of `requests.Session` is `httpx.Client`.
|
|
||||||
|
|
||||||
```python
|
|
||||||
session = requests.Session(**kwargs)
|
|
||||||
```
|
|
||||||
|
|
||||||
is generally equivalent to
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client(**kwargs)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Request URLs
|
|
||||||
|
|
||||||
Accessing `response.url` will return a `URL` instance, rather than a string.
|
|
||||||
|
|
||||||
Use `str(response.url)` if you need a string instance.
|
|
||||||
|
|
||||||
## Determining the next redirect request
|
|
||||||
|
|
||||||
The `requests` library exposes an attribute `response.next`, which can be used to obtain the next redirect request.
|
|
||||||
|
|
||||||
```python
|
|
||||||
session = requests.Session()
|
|
||||||
request = requests.Request("GET", ...).prepare()
|
|
||||||
while request is not None:
|
|
||||||
response = session.send(request, allow_redirects=False)
|
|
||||||
request = response.next
|
|
||||||
```
|
|
||||||
|
|
||||||
In HTTPX, this attribute is instead named `response.next_request`. For example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client()
|
|
||||||
request = client.build_request("GET", ...)
|
|
||||||
while request is not None:
|
|
||||||
response = client.send(request)
|
|
||||||
request = response.next_request
|
|
||||||
```
|
|
||||||
|
|
||||||
## Request Content
|
|
||||||
|
|
||||||
For uploading raw text or binary content we prefer to use a `content` parameter,
|
|
||||||
in order to better separate this usage from the case of uploading form data.
|
|
||||||
|
|
||||||
For example, using `content=...` to upload raw content:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Uploading text, bytes, or a bytes iterator.
|
|
||||||
httpx.post(..., content=b"Hello, world")
|
|
||||||
```
|
|
||||||
|
|
||||||
And using `data=...` to send form data:
|
|
||||||
|
|
||||||
```python
|
|
||||||
# Uploading form data.
|
|
||||||
httpx.post(..., data={"message": "Hello, world"})
|
|
||||||
```
|
|
||||||
|
|
||||||
Using the `data=<text/byte content>` will raise a deprecation warning,
|
|
||||||
and is expected to be fully removed with the HTTPX 1.0 release.
|
|
||||||
|
|
||||||
## Upload files
|
|
||||||
|
|
||||||
HTTPX strictly enforces that upload files must be opened in binary mode, in order
|
|
||||||
to avoid character encoding issues that can result from attempting to upload files
|
|
||||||
opened in text mode.
|
|
||||||
|
|
||||||
## Content encoding
|
|
||||||
|
|
||||||
HTTPX uses `utf-8` for encoding `str` request bodies. For example, when using `content=<str>` the request body will be encoded to `utf-8` before being sent over the wire. This differs from Requests which uses `latin1`. If you need an explicit encoding, pass encoded bytes explicitly, e.g. `content=<str>.encode("latin1")`.
|
|
||||||
For response bodies, assuming the server didn't send an explicit encoding then HTTPX will do its best to figure out an appropriate encoding. HTTPX makes a guess at the encoding to use for decoding the response using `charset_normalizer`. Fallback to that or any content with less than 32 octets will be decoded using `utf-8` with the `error="replace"` decoder strategy.
|
|
||||||
|
|
||||||
## Cookies
|
|
||||||
|
|
||||||
If using a client instance, then cookies should always be set on the client rather than on a per-request basis.
|
|
||||||
|
|
||||||
This usage is supported:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client(cookies=...)
|
|
||||||
client.post(...)
|
|
||||||
```
|
|
||||||
|
|
||||||
This usage is **not** supported:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.Client()
|
|
||||||
client.post(..., cookies=...)
|
|
||||||
```
|
|
||||||
|
|
||||||
We prefer enforcing a stricter API here because it provides clearer expectations around cookie persistence, particularly when redirects occur.
|
|
||||||
|
|
||||||
## Status Codes
|
|
||||||
|
|
||||||
In our documentation we prefer the uppercased versions, such as `codes.NOT_FOUND`, but also provide lower-cased versions for API compatibility with `requests`.
|
|
||||||
|
|
||||||
Requests includes various synonyms for status codes that HTTPX does not support.
|
|
||||||
|
|
||||||
## Streaming responses
|
|
||||||
|
|
||||||
HTTPX provides a `.stream()` interface rather than using `stream=True`. This ensures that streaming responses are always properly closed outside of the stream block, and makes it visually clearer at which points streaming I/O APIs may be used with a response.
|
|
||||||
|
|
||||||
For example:
|
|
||||||
|
|
||||||
```python
|
|
||||||
with httpx.stream("GET", "https://www.example.com") as response:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
Within a `stream()` block request data is made available with:
|
|
||||||
|
|
||||||
* `.iter_bytes()` - Instead of `response.iter_content()`
|
|
||||||
* `.iter_text()` - Instead of `response.iter_content(decode_unicode=True)`
|
|
||||||
* `.iter_lines()` - Corresponding to `response.iter_lines()`
|
|
||||||
* `.iter_raw()` - Use this instead of `response.raw`
|
|
||||||
* `.read()` - Read the entire response body, making `response.text` and `response.content` available.
|
|
||||||
|
|
||||||
## Timeouts
|
|
||||||
|
|
||||||
HTTPX defaults to including reasonable [timeouts](quickstart.md#timeouts) for all network operations, while Requests has no timeouts by default.
|
|
||||||
|
|
||||||
To get the same behavior as Requests, set the `timeout` parameter to `None`:
|
|
||||||
|
|
||||||
```python
|
|
||||||
httpx.get('https://www.example.com', timeout=None)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Proxy keys
|
|
||||||
|
|
||||||
HTTPX uses the mounts argument for HTTP proxying and transport routing.
|
|
||||||
It can do much more than proxies and allows you to configure more than just the proxy route.
|
|
||||||
For more detailed documentation, see [Mounting Transports](advanced/transports.md#mounting-transports).
|
|
||||||
|
|
||||||
When using `httpx.Client(mounts={...})` to map to a selection of different transports, we use full URL schemes, such as `mounts={"http://": ..., "https://": ...}`.
|
|
||||||
|
|
||||||
This is different to the `requests` usage of `proxies={"http": ..., "https": ...}`.
|
|
||||||
|
|
||||||
This change is for better consistency with more complex mappings, that might also include domain names, such as `mounts={"all://": ..., httpx.HTTPTransport(proxy="all://www.example.com": None})` which maps all requests onto a proxy, except for requests to "www.example.com" which have an explicit exclusion.
|
|
||||||
|
|
||||||
Also note that `requests.Session.request(...)` allows a `proxies=...` parameter, whereas `httpx.Client.request(...)` does not allow `mounts=...`.
|
|
||||||
|
|
||||||
## SSL configuration
|
|
||||||
|
|
||||||
When using a `Client` instance, the ssl configurations should always be passed on client instantiation, rather than passed to the request method.
|
|
||||||
|
|
||||||
If you need more than one different SSL configuration, you should use different client instances for each SSL configuration.
|
|
||||||
|
|
||||||
## Request body on HTTP methods
|
|
||||||
|
|
||||||
The HTTP `GET`, `DELETE`, `HEAD`, and `OPTIONS` methods are specified as not supporting a request body. To stay in line with this, the `.get`, `.delete`, `.head` and `.options` functions do not support `content`, `files`, `data`, or `json` arguments.
|
|
||||||
|
|
||||||
If you really do need to send request data using these http methods you should use the generic `.request` function instead.
|
|
||||||
|
|
||||||
```python
|
|
||||||
httpx.request(
|
|
||||||
method="DELETE",
|
|
||||||
url="https://www.example.com/",
|
|
||||||
content=b'A request body on a DELETE request.'
|
|
||||||
)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Checking for success and failure responses
|
|
||||||
|
|
||||||
We don't support `response.is_ok` since the naming is ambiguous there, and might incorrectly imply an equivalence to `response.status_code == codes.OK`. Instead we provide the `response.is_success` property, which can be used to check for a 2xx response.
|
|
||||||
|
|
||||||
## Request instantiation
|
|
||||||
|
|
||||||
There is no notion of [prepared requests](https://requests.readthedocs.io/en/stable/user/advanced/#prepared-requests) in HTTPX. If you need to customize request instantiation, see [Request instances](advanced/clients.md#request-instances).
|
|
||||||
|
|
||||||
Besides, `httpx.Request()` does not support the `auth`, `timeout`, `follow_redirects`, `mounts`, `verify` and `cert` parameters. However these are available in `httpx.request`, `httpx.get`, `httpx.post` etc., as well as on [`Client` instances](advanced/clients.md#client-instances).
|
|
||||||
|
|
||||||
## Mocking
|
|
||||||
|
|
||||||
If you need to mock HTTPX the same way that test utilities like `responses` and `requests-mock` does for `requests`, see [RESPX](https://github.com/lundberg/respx).
|
|
||||||
|
|
||||||
## Caching
|
|
||||||
|
|
||||||
If you use `cachecontrol` or `requests-cache` to add HTTP Caching support to the `requests` library, you can use [Hishel](https://hishel.com) for HTTPX.
|
|
||||||
|
|
||||||
## Networking layer
|
|
||||||
|
|
||||||
`requests` defers most of its HTTP networking code to the excellent [`urllib3` library](https://urllib3.readthedocs.io/en/latest/).
|
|
||||||
|
|
||||||
On the other hand, HTTPX uses [HTTPCore](https://github.com/encode/httpcore) as its core HTTP networking layer, which is a different project than `urllib3`.
|
|
||||||
|
|
||||||
## Query Parameters
|
|
||||||
|
|
||||||
`requests` omits `params` whose values are `None` (e.g. `requests.get(..., params={"foo": None})`). This is not supported by HTTPX.
|
|
||||||
|
|
||||||
For both query params (`params=`) and form data (`data=`), `requests` supports sending a list of tuples (e.g. `requests.get(..., params=[('key1', 'value1'), ('key1', 'value2')])`). This is not supported by HTTPX. Instead, use a dictionary with lists as values. E.g.: `httpx.get(..., params={'key1': ['value1', 'value2']})` or with form data: `httpx.post(..., data={'key1': ['value1', 'value2']})`.
|
|
||||||
|
|
||||||
## Event Hooks
|
|
||||||
|
|
||||||
`requests` allows event hooks to mutate `Request` and `Response` objects. See [examples](https://requests.readthedocs.io/en/master/user/advanced/#event-hooks) given in the documentation for `requests`.
|
|
||||||
|
|
||||||
In HTTPX, event hooks may access properties of requests and responses, but event hook callbacks cannot mutate the original request/response.
|
|
||||||
|
|
||||||
If you are looking for more control, consider checking out [Custom Transports](advanced/transports.md#custom-transports).
|
|
||||||
|
|
||||||
## Exceptions and Errors
|
|
||||||
|
|
||||||
`requests` exception hierarchy is slightly different to the `httpx` exception hierarchy. `requests` exposes a top level `RequestException`, where as `httpx` exposes a top level `HTTPError`. see the exceptions exposes in requests [here](https://requests.readthedocs.io/en/latest/_modules/requests/exceptions/). See the `httpx` error hierarchy [here](https://www.python-httpx.org/exceptions/).

# Connections
|
||||||
|
|
||||||
|
The mechanics of sending HTTP requests is dealt with by the `ConnectionPool` and `Connection` classes.
|
||||||
|
|
||||||
|
We can introspect a `Client` instance to get some visibility onto the state of the connection pool.
|
||||||
|
|
||||||

## Understanding the stack
|
||||||
|
|
||||||
|
The `Client` class is responsible for handling redirects and cookies.
|
||||||
|
|
||||||
|
It also ensures that outgoing requests include a default set of headers such as `User-Agent` and `Accept-Encoding`.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> with httpx.Client() as cli:
|
||||||
|
>>> r = cli.request("GET", "https://www.example.com/")
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> async with ahttpx.Client() as cli:
|
||||||
|
>>> r = await cli.request("GET", "https://www.example.com/")
|
||||||
|
```
|
||||||
|
|
||||||
|
The `Client` class sends requests using a `ConnectionPool`, which is responsible for managing a pool of HTTP connections. This ensures quicker and more efficient use of resources than opening and closing a TCP connection with each request. The connection pool also handles HTTP proxying if required.
|
||||||
|
|
||||||
|
A single connection pool is able to handle multiple concurrent requests, with locking in place to ensure that the pool does not become over-saturated.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> with httpx.ConnectionPool() as pool:
|
||||||
|
>>> r = pool.request("GET", "https://www.example.com/")
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> async with ahttpx.ConnectionPool() as pool:
|
||||||
|
>>> r = await pool.request("GET", "https://www.example.com/")
|
||||||
|
```
|
||||||
|
|
||||||
|
Individual HTTP connections can be managed directly with the `Connection` class. A single connection can only handle requests sequentially. Locking is provided to ensure that requests are strictly queued sequentially.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> with httpx.open_connection("https://www.example.com/") as conn:
|
||||||
|
>>> r = conn.request("GET", "/")
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> async with ahttpx.open_connection("https://www.example.com/") as conn:
|
||||||
|
>>> r = await conn.request("GET", "/")
|
||||||
|
```
|
||||||
|
|
||||||
|
The `NetworkBackend` is responsible for managing the TCP stream, providing a raw byte-wise interface onto the underlying socket.

# Content Types
|
||||||
|
|
||||||
|
Some HTTP requests including `POST`, `PUT` and `PATCH` can include content in the body of the request.
|
||||||
|
|
||||||
|
The most common content types for upload data are...
|
||||||
|
|
||||||
|
* HTML form submissions use the `application/x-www-form-urlencoded` content type.
|
||||||
|
* HTML form submissions including file uploads use the `multipart/form-data` content type.
|
||||||
|
* JSON data uses the `application/json` content type.
|
||||||
|
|
||||||
|
Content can be included directly in a request by using bytes or a byte iterator and setting the appropriate `Content-Type` header.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> headers = {'Content-Type': 'application/json'}
|
||||||
|
>>> content = json.dumps({"number": 123.5, "bool": [True, False], "text": "hello"})
|
||||||
|
>>> response = cli.put(url, headers=headers, content=content)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> headers = {'Content-Type': 'application/json'}
|
||||||
|
>>> content = json.dumps({"number": 123.5, "bool": [True, False], "text": "hello"})
|
||||||
|
>>> response = await cli.put(url, headers=headers, content=content)
|
||||||
|
```
|
||||||
|
|
||||||
|
There are also several classes provided for setting the request content. These implement either the `Content` or `StreamingContent` API, and handle constructing the content and setting the relevant headers.
|
||||||
|
|
||||||
|
* `<Form {“email”: “heya@noodles.com”}>`
|
||||||
|
* `<Files {“upload”: File("README.md”)}>`
|
||||||
|
* `<File “README.md” [123MB]>`
|
||||||
|
* `<MultiPart {} {“upload”: File("README.md”)}>`
|
||||||
|
* `<JSON {"number": 123.5, "bool": [True, False], ...}>`
|
||||||
|
|
||||||
|
For example, sending a JSON request...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> data = httpx.JSON({"number": 123.5, "bool": [True, False], "text": "hello"})
|
||||||
|
>>> cli.post(url, content=data)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> data = httpx.JSON({"number": 123.5, "bool": [True, False], "text": "hello"})
|
||||||
|
>>> await cli.post(url, content=data)
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Form
|
||||||
|
|
||||||
|
The `Form` class provides an immutable multi-dict for accessing HTML form data. This class implements the `Content` interface, allowing for HTML form uploads.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> form = httpx.Form({'name': '...'})
|
||||||
|
>>> form
|
||||||
|
...
|
||||||
|
>>> form['name']
|
||||||
|
...
|
||||||
|
>>> res = cli.post(url, content=form)
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> form = httpx.Form({'name': '...'})
|
||||||
|
>>> form
|
||||||
|
...
|
||||||
|
>>> form['name']
|
||||||
|
...
|
||||||
|
>>> res = await cli.post(url, content=form)
|
||||||
|
...
|
||||||
|
```

The `Files` class provides an immutable multi-dict for accessing HTML form file uploads. This class implements the `StreamingContent` interface, allowing for HTML form file uploads.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> files = httpx.Files({'upload': httpx.File('data.json')})
|
||||||
|
>>> files
|
||||||
|
...
|
||||||
|
>>> files['upload']
|
||||||
|
...
|
||||||
|
>>> res = cli.post(url, content=files)
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> files = httpx.Files({'upload': httpx.File('data.json')})
|
||||||
|
>>> files
|
||||||
|
...
|
||||||
|
>>> files['upload']
|
||||||
|
...
|
||||||
|
>>> res = await cli.post(url, content=files)
|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
## MultiPart
|
||||||
|
|
||||||
|
The `MultiPart` class provides a wrapper for HTML form and files uploads. This class implements the `StreamingContent` interface, allowing for allowing for HTML form uploads including both data and file uploads.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> multipart = httpx.MultiPart(form={'name': '...'}, files={'avatar': httpx.File('image.png')})
|
||||||
|
>>> multipart.form['name']
|
||||||
|
...
|
||||||
|
>>> multipart.files['avatar']
|
||||||
|
...
|
||||||
|
>>> res = cli.post(url, content=multipart)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> multipart = httpx.MultiPart(form={'name': '...'}, files={'avatar': httpx.File('image.png')})
|
||||||
|
>>> multipart.form['name']
|
||||||
|
...
|
||||||
|
>>> multipart.files['avatar']
|
||||||
|
...
|
||||||
|
>>> res = await cli.post(url, content=multipart)
|
||||||
|
```
|
||||||
|
|
||||||
|
## File
|
||||||
|
|
||||||
|
The `File` class provides a wrapper for file uploads, and is used for uploads instead of passing a file object directly.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> file = httpx.File('upload.json')
|
||||||
|
>>> cli.post(url, content=file)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> file = httpx.File('upload.json')
|
||||||
|
>>> await cli.post(url, content=file)
|
||||||
|
```
|
||||||
|
|
||||||
|
## JSON
|
||||||
|
|
||||||
|
The `JSON` class provides a wrapper for JSON uploads. This class implements the `Content` interface, allowing for HTTP JSON uploads.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> data = httpx.JSON({...})
|
||||||
|
>>> cli.put(url, content=data)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> data = httpx.JSON({...})
|
||||||
|
>>> await cli.put(url, content=data)
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Content
|
||||||
|
|
||||||
|
An interface for constructing HTTP content, along with relevant headers.
|
||||||
|
|
||||||
|
The following method must be implemented...
|
||||||
|
|
||||||
|
* `.encode()` - Returns an `httx.Stream` representing the encoded data.
|
||||||
|
* `.content_type()` - Returns a `str` indicating the content type.

# Contributing
|
|
||||||
|
|
||||||
Thank you for being interested in contributing to HTTPX.
|
|
||||||
There are many ways you can contribute to the project:
|
|
||||||
|
|
||||||
- Try HTTPX and [report bugs/issues you find](https://github.com/encode/httpx/issues/new)
|
|
||||||
- [Implement new features](https://github.com/encode/httpx/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22)
|
|
||||||
- [Review Pull Requests of others](https://github.com/encode/httpx/pulls)
|
|
||||||
- Write documentation
|
|
||||||
- Participate in discussions
|
|
||||||
|
|
||||||
## Reporting Bugs or Other Issues
|
|
||||||
|
|
||||||
Found something that HTTPX should support?
|
|
||||||
Stumbled upon some unexpected behaviour?
|
|
||||||
|
|
||||||
Contributions should generally start out with [a discussion](https://github.com/encode/httpx/discussions).
|
|
||||||
Possible bugs may be raised as a "Potential Issue" discussion, feature requests may
|
|
||||||
be raised as an "Ideas" discussion. We can then determine if the discussion needs
|
|
||||||
to be escalated into an "Issue" or not, or if we'd consider a pull request.
|
|
||||||
|
|
||||||
Try to be more descriptive as you can and in case of a bug report,
|
|
||||||
provide as much information as possible like:
|
|
||||||
|
|
||||||
- OS platform
|
|
||||||
- Python version
|
|
||||||
- Installed dependencies and versions (`python -m pip freeze`)
|
|
||||||
- Code snippet
|
|
||||||
- Error traceback
|
|
||||||
|
|
||||||
You should always try to reduce any examples to the *simplest possible case*
|
|
||||||
that demonstrates the issue.
|
|
||||||
|
|
||||||
Some possibly useful tips for narrowing down potential issues...
|
|
||||||
|
|
||||||
- Does the issue exist on HTTP/1.1, or HTTP/2, or both?
|
|
||||||
- Does the issue exist with `Client`, `AsyncClient`, or both?
|
|
||||||
- When using `AsyncClient` does the issue exist when using `asyncio` or `trio`, or both?
|
|
||||||
|
|
||||||
## Development
|
|
||||||
|
|
||||||
To start developing HTTPX create a **fork** of the
|
|
||||||
[HTTPX repository](https://github.com/encode/httpx) on GitHub.
|
|
||||||
|
|
||||||
Then clone your fork with the following command replacing `YOUR-USERNAME` with
|
|
||||||
your GitHub username:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ git clone https://github.com/YOUR-USERNAME/httpx
|
|
||||||
```
|
|
||||||
|
|
||||||
You can now install the project and its dependencies using:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ cd httpx
|
|
||||||
$ scripts/install
|
|
||||||
```
|
|
||||||
|
|
||||||
## Testing and Linting
|
|
||||||
|
|
||||||
We use custom shell scripts to automate testing, linting,
|
|
||||||
and documentation building workflow.
|
|
||||||
|
|
||||||
To run the tests, use:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/test
|
|
||||||
```
|
|
||||||
|
|
||||||
!!! warning
|
|
||||||
The test suite spawns testing servers on ports **8000** and **8001**.
|
|
||||||
Make sure these are not in use, so the tests can run properly.
|
|
||||||
|
|
||||||
Any additional arguments will be passed to `pytest`. See the [pytest documentation](https://docs.pytest.org/en/latest/how-to/usage.html) for more information.
|
|
||||||
|
|
||||||
For example, to run a single test script:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/test tests/test_multipart.py
|
|
||||||
```
|
|
||||||
|
|
||||||
To run the code auto-formatting:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/lint
|
|
||||||
```
|
|
||||||
|
|
||||||
Lastly, to run code checks separately (they are also run as part of `scripts/test`), run:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/check
|
|
||||||
```
|
|
||||||
|
|
||||||
## Documenting
|
|
||||||
|
|
||||||
Documentation pages are located under the `docs/` folder.
|
|
||||||
|
|
||||||
To run the documentation site locally (useful for previewing changes), use:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/docs
|
|
||||||
```
|
|
||||||
|
|
||||||
## Resolving Build / CI Failures
|
|
||||||
|
|
||||||
Once you've submitted your pull request, the test suite will automatically run, and the results will show up in GitHub.
|
|
||||||
If the test suite fails, you'll want to click through to the "Details" link, and try to identify why the test suite failed.
|
|
||||||
|
|
||||||

|
|
||||||
<img src="https://raw.githubusercontent.com/encode/httpx/master/docs/img/gh-actions-fail.png" alt='Failing PR commit status'>
|
|
||||||
</p>
|
|
||||||
|
|
||||||
Here are some common ways the test suite can fail:
|
|
||||||
|
|
||||||
### Check Job Failed
|
|
||||||
|
|
||||||
<p align="center" style="margin: 0 0 10px">
|
|
||||||
<img src="https://raw.githubusercontent.com/encode/httpx/master/docs/img/gh-actions-fail-check.png" alt='Failing GitHub action lint job'>
|
|
||||||
</p>
|
|
||||||
|
|
||||||
This job failing means there is either a code formatting issue or type-annotation issue.
|
|
||||||
You can look at the job output to figure out why it's failed or within a shell run:
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ scripts/check
|
|
||||||
```
|
|
||||||
|
|
||||||
It may be worth it to run `$ scripts/lint` to attempt auto-formatting the code
|
|
||||||
and if that job succeeds commit the changes.
|
|
||||||
|
|
||||||
### Docs Job Failed
|
|
||||||
|
|
||||||
This job failing means the documentation failed to build. This can happen for
|
|
||||||
a variety of reasons like invalid markdown or missing configuration within `mkdocs.yml`.
|
|
||||||
|
|
||||||
### Python 3.X Job Failed
|
|
||||||
|
|
||||||
<p align="center" style="margin: 0 0 10px">
|
|
||||||
<img src="https://raw.githubusercontent.com/encode/httpx/master/docs/img/gh-actions-fail-test.png" alt='Failing GitHub action test job'>
|
|
||||||
</p>
|
|
||||||
|
|
||||||
This job failing means the unit tests failed or not all code paths are covered by unit tests.
|
|
||||||
|
|
||||||
If tests are failing you will see this message under the coverage report:
|
|
||||||
|
|
||||||
`=== 1 failed, 435 passed, 1 skipped, 1 xfailed in 11.09s ===`
|
|
||||||
|
|
||||||
If tests succeed but coverage doesn't reach our current threshold, you will see this
|
|
||||||
message under the coverage report:
|
|
||||||
|
|
||||||
`FAIL Required test coverage of 100% not reached. Total coverage: 99.00%`
|
|
||||||
|
|
||||||
## Releasing
|
|
||||||
|
|
||||||
*This section is targeted at HTTPX maintainers.*
|
|
||||||
|
|
||||||
Before releasing a new version, create a pull request that includes:
|
|
||||||
|
|
||||||
- **An update to the changelog**:
|
|
||||||
- We follow the format from [keepachangelog](https://keepachangelog.com/en/1.0.0/).
|
|
||||||
- [Compare](https://github.com/encode/httpx/compare/) `master` with the tag of the latest release, and list all entries that are of interest to our users:
|
|
||||||
- Things that **must** go in the changelog: added, changed, deprecated or removed features, and bug fixes.
|
|
||||||
- Things that **should not** go in the changelog: changes to documentation, tests or tooling.
|
|
||||||
- Try sorting entries in descending order of impact / importance.
|
|
||||||
- Keep it concise and to-the-point. 🎯
|
|
||||||
- **A version bump**: see `__version__.py`.
|
|
||||||
|
|
||||||
For an example, see [#1006](https://github.com/encode/httpx/pull/1006).
|
|
||||||
|
|
||||||
Once the release PR is merged, create a
|
|
||||||
[new release](https://github.com/encode/httpx/releases/new) including:
|
|
||||||
|
|
||||||
- Tag version like `0.13.3`.
|
|
||||||
- Release title `Version 0.13.3`
|
|
||||||
- Description copied from the changelog.
|
|
||||||
|
|
||||||
Once created this release will be automatically uploaded to PyPI.
|
|
||||||
|
|
||||||
If something goes wrong with the PyPI job the release can be published using the
|
|
||||||
`scripts/publish` script.
|
|
||||||
|
|
||||||
## Development proxy setup
|
|
||||||
|
|
||||||
To test and debug requests via a proxy it's best to run a proxy server locally.
|
|
||||||
Any server should do but HTTPCore's test suite uses
|
|
||||||
[`mitmproxy`](https://mitmproxy.org/) which is written in Python, it's fully
|
|
||||||
featured and has excellent UI and tools for introspection of requests.
|
|
||||||
|
|
||||||
You can install `mitmproxy` using `pip install mitmproxy` or [several
|
|
||||||
other ways](https://docs.mitmproxy.org/stable/overview-installation/).
|
|
||||||
|
|
||||||
`mitmproxy` does require setting up local TLS certificates for HTTPS requests,
|
|
||||||
as its main purpose is to allow developers to inspect requests that pass through
|
|
||||||
it. We can set them up follows:
|
|
||||||
|
|
||||||
1. [`pip install trustme-cli`](https://github.com/sethmlarson/trustme-cli/).
|
|
||||||
2. `trustme-cli -i example.org www.example.org`, assuming you want to test
|
|
||||||
connecting to that domain, this will create three files: `server.pem`,
|
|
||||||
`server.key` and `client.pem`.
|
|
||||||
3. `mitmproxy` requires a PEM file that includes the private key and the
|
|
||||||
certificate so we need to concatenate them:
|
|
||||||
`cat server.key server.pem > server.withkey.pem`.
|
|
||||||
4. Start the proxy server `mitmproxy --certs server.withkey.pem`, or use the
|
|
||||||
[other mitmproxy commands](https://docs.mitmproxy.org/stable/) with different
|
|
||||||
UI options.
|
|
||||||
|
|
||||||
At this point the server is ready to start serving requests, you'll need to
|
|
||||||
configure HTTPX as described in the
|
|
||||||
[proxy section](https://www.python-httpx.org/advanced/proxies/#http-proxies) and
|
|
||||||
the [SSL certificates section](https://www.python-httpx.org/advanced/ssl/),
|
|
||||||
this is where our previously generated `client.pem` comes in:
|
|
||||||
|
|
||||||
```python
|
|
||||||
ctx = ssl.create_default_context(cafile="/path/to/client.pem")
|
|
||||||
client = httpx.Client(proxy="http://127.0.0.1:8080/", verify=ctx)
|
|
||||||
```
|
|
||||||
|
|
||||||
Note, however, that HTTPS requests will only succeed to the host specified
|
|
||||||
in the SSL/TLS certificate we generated, HTTPS requests to other hosts will
|
|
||||||
raise an error like:
|
|
||||||
|
|
||||||
```
|
|
||||||
ssl.SSLCertVerificationError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate
|
|
||||||
verify failed: Hostname mismatch, certificate is not valid for
|
|
||||||
'duckduckgo.com'. (_ssl.c:1108)
|
|
||||||
```
|
|
||||||
|
|
||||||
If you want to make requests to more hosts you'll need to regenerate the
|
|
||||||
certificates and include all the hosts you intend to connect to in the
|
|
||||||
seconds step, i.e.
|
|
||||||
|
|
||||||
`trustme-cli -i example.org www.example.org duckduckgo.com www.duckduckgo.com`

# Environment Variables
|
|
||||||
|
|
||||||
The HTTPX library can be configured via environment variables.
|
|
||||||
Environment variables are used by default. To ignore environment variables, `trust_env` has to be set `False`. There are two ways to set `trust_env` to disable environment variables:
|
|
||||||
|
|
||||||
* On the client via `httpx.Client(trust_env=False)`.
|
|
||||||
* Using the top-level API, such as `httpx.get("<url>", trust_env=False)`.
|
|
||||||
|
|
||||||
Here is a list of environment variables that HTTPX recognizes and what function they serve:
|
|
||||||
|
|
||||||
## Proxies
|
|
||||||
|
|
||||||
The environment variables documented below are used as a convention by various HTTP tooling, including:
|
|
||||||
|
|
||||||
* [cURL](https://github.com/curl/curl/blob/master/docs/MANUAL.md#environment-variables)
|
|
||||||
* [requests](https://github.com/psf/requests/blob/master/docs/user/advanced.rst#proxies)
|
|
||||||
|
|
||||||
For more information on using proxies in HTTPX, see [HTTP Proxying](advanced/proxies.md#http-proxying).
|
|
||||||
|
|
||||||
### `HTTP_PROXY`, `HTTPS_PROXY`, `ALL_PROXY`
|
|
||||||
|
|
||||||
Valid values: A URL to a proxy
|
|
||||||
|
|
||||||
`HTTP_PROXY`, `HTTPS_PROXY`, `ALL_PROXY` set the proxy to be used for `http`, `https`, or all requests respectively.
|
|
||||||
|
|
||||||
```bash
|
|
||||||
export HTTP_PROXY=http://my-external-proxy.com:1234
|
|
||||||
|
|
||||||
# This request will be sent through the proxy
|
|
||||||
python -c "import httpx; httpx.get('http://example.com')"
|
|
||||||
|
|
||||||
# This request will be sent directly, as we set `trust_env=False`
|
|
||||||
python -c "import httpx; httpx.get('http://example.com', trust_env=False)"
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
### `NO_PROXY`
|
|
||||||
|
|
||||||
Valid values: a comma-separated list of hostnames/urls
|
|
||||||
|
|
||||||
`NO_PROXY` disables the proxy for specific urls
|
|
||||||
|
|
||||||
```bash
|
|
||||||
export HTTP_PROXY=http://my-external-proxy.com:1234
|
|
||||||
export NO_PROXY=http://127.0.0.1,python-httpx.org
|
|
||||||
|
|
||||||
# As in the previous example, this request will be sent through the proxy
|
|
||||||
python -c "import httpx; httpx.get('http://example.com')"
|
|
||||||
|
|
||||||
# These requests will be sent directly, bypassing the proxy
|
|
||||||
python -c "import httpx; httpx.get('http://127.0.0.1:5000/my-api')"
|
|
||||||
python -c "import httpx; httpx.get('https://www.python-httpx.org')"
|
|
||||||
```
|
|
||||||
|
|
||||||
## `SSL_CERT_FILE`
|
|
||||||
|
|
||||||
Valid values: a filename
|
|
||||||
|
|
||||||
If this environment variable is set then HTTPX will load
|
|
||||||
CA certificate from the specified file instead of the default
|
|
||||||
location.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|

```
|
|
||||||
|
|

## `SSL_CERT_DIR`
|
|
||||||
|
|
||||||
Valid values: a directory following an [OpenSSL specific layout](https://www.openssl.org/docs/manmaster/man3/SSL_CTX_load_verify_locations.html).
|
|
||||||
|
|
||||||
If this environment variable is set and the directory follows an [OpenSSL specific layout](https://www.openssl.org/docs/manmaster/man3/SSL_CTX_load_verify_locations.html) (ie. you ran `c_rehash`) then HTTPX will load CA certificates from this directory instead of the default location.
|
|
||||||
|
|
||||||
Example:
|
|
||||||
|
|
||||||
```console
|
|
||||||
SSL_CERT_DIR=/path/to/ca-certs/ python -c "import httpx; httpx.get('https://example.com')"

# Headers
|
||||||
|
|
||||||
|
The `Headers` class provides an immutable case-insensitive multidict interface for accessing HTTP headers.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> headers = httpx.Headers({"Accept": "*/*"})
|
||||||
|
>>> headers
|
||||||
|
<Headers {"Accept": "*/*"}>
|
||||||
|
>>> headers['accept']
|
||||||
|
'*/*'
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> headers = ahttpx.Headers({"Accept": "*/*"})
|
||||||
|
>>> headers
|
||||||
|
<Headers {"Accept": "*/*"}>
|
||||||
|
>>> headers['accept']
|
||||||
|
'*/*'
|
||||||
|
```
|
||||||
|
|
||||||
|
Header values should always be printable ASCII strings. Attempting to set invalid header name or value strings will raise a `ValueError`.
|
||||||
|
|
||||||
|
### Accessing headers
|
||||||
|
|
||||||
|
Headers are accessed using a standard dictionary style interface...
|
||||||
|
|
||||||
|
* `.get(key, default=None)` - *Return the value for a given key, or a default value. If multiple values for the key are present, only the first will be returned.*
|
||||||
|
* `.keys()` - *Return the unique keys of the headers. Each key will be a `str`.*
|
||||||
|
* `.values()` - *Return the values of the headers. Each value will be a `str`. If multiple values for a key are present, only the first will be returned.*
|
||||||
|
* `.items()` - *Return the key value pairs of the headers. Each item will be a two-tuple `(str, str)`. If multiple values for a key are present, only the first will be returned.*
|
||||||
|
|
||||||
|
The following methods are also available for accessing headers as a multidict...
|
||||||
|
|
||||||
|
* `.get_all(key, comma_delimited=False)` - *Return all the values for a given key. Returned as a list of zero or more `str` instances. If `comma_delimited` is set to `True` then any comma separated header values are split into a list of strings.*
|
||||||
|
* `.multi_items()` - *Return the key value pairs of the headers. Each item will be a two-tuple `(str, str)`. Repeated keys may occur.*
|
||||||
|
* `.multi_dict()` - *Return the headers as a dictionary, with each value being a list of one or more `str` instances.*
|
||||||
|
|
||||||
|
### Modifying headers
|
||||||
|
|
||||||
|
The following methods can be used to create modified header instances...
|
||||||
|
|
||||||
|
* `.copy_set(key, value)` - *Return a new `Headers` instances, setting a header. Eg. `headers = headers.copy_set("Connection": "close")`*.
|
||||||
|
* `.copy_setdefault(key, value)` - *Return a new `Headers` instances, setting a header if it does not yet exist. Eg. `headers = headers.copy_setdefault("Content-Type": "text/html")`*.
|
||||||
|
* `.copy_append(key, value, comma_delimited=False)` - *Return a new `Headers` instances, setting or appending a header. If `comma_delimited` is set to `True`, then the append will be handled using comma delimiting instead of creating a new header. Eg. `headers = headers.copy_append("Accept-Encoding", "gzip", comma_delimited=True)`*.
|
||||||
|
* `.copy_remove(key)` - *Return a new `Headers` instances, removing a header. Eg. `headers = headers.copy_remove("User-Agent")`*.
|
||||||
|
* `.copy_update(headers)` - *Return a new `Headers` instances, updating multiple headers. Eg. `headers = headers.copy_update({"Authorization": "top secret"})`*.

# HTTP/2
|
|
||||||
|
|
||||||
HTTP/2 is a major new iteration of the HTTP protocol, that provides a far more
|
|
||||||
efficient transport, with potential performance benefits. HTTP/2 does not change
|
|
||||||
the core semantics of the request or response, but alters the way that data is
|
|
||||||
sent to and from the server.
|
|
||||||
|
|
||||||
Rather than the text format that HTTP/1.1 uses, HTTP/2 is a binary format.
|
|
||||||
The binary format provides full request and response multiplexing, and efficient
|
|
||||||
compression of HTTP headers. The stream multiplexing means that where HTTP/1.1
|
|
||||||
requires one TCP stream for each concurrent request, HTTP/2 allows a single TCP
|
|
||||||
stream to handle multiple concurrent requests.
|
|
||||||
|
|
||||||
HTTP/2 also provides support for functionality such as response prioritization,
|
|
||||||
and server push.
|
|
||||||
|
|
||||||
For a comprehensive guide to HTTP/2 you may want to check out "[http2 explained](https://http2-explained.haxx.se/)".
|
|
||||||
|
|
||||||
## Enabling HTTP/2
|
|
||||||
|
|
||||||
When using the `httpx` client, HTTP/2 support is not enabled by default, because
|
|
||||||
HTTP/1.1 is a mature, battle-hardened transport layer, and our HTTP/1.1
|
|
||||||
implementation may be considered the more robust option at this point in time.
|
|
||||||
It is possible that a future version of `httpx` may enable HTTP/2 support by default.
|
|
||||||
|
|
||||||
If you're issuing highly concurrent requests you might want to consider
|
|
||||||
trying out our HTTP/2 support. You can do so by first making sure to install
|
|
||||||
the optional HTTP/2 dependencies...
|
|
||||||
|
|
||||||
```shell
|
|
||||||
$ pip install httpx[http2]
|
|
||||||
```
|
|
||||||
|
|
||||||
And then instantiating a client with HTTP/2 support enabled:
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.AsyncClient(http2=True)
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
You can also instantiate a client as a context manager, to ensure that all
|
|
||||||
HTTP connections are nicely scoped, and will be closed once the context block
|
|
||||||
is exited.
|
|
||||||
|
|
||||||
```python
|
|
||||||
async with httpx.AsyncClient(http2=True) as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
HTTP/2 support is available on both `Client` and `AsyncClient`, although it's
|
|
||||||
typically more useful in async contexts if you're issuing lots of concurrent
|
|
||||||
requests.
|
|
||||||
|
|
||||||
## Inspecting the HTTP version
|
|
||||||
|
|
||||||
Enabling HTTP/2 support on the client does not *necessarily* mean that your
|
|
||||||
requests and responses will be transported over HTTP/2, since both the client
|
|
||||||
*and* the server need to support HTTP/2. If you connect to a server that only
|
|
||||||
supports HTTP/1.1 the client will use a standard HTTP/1.1 connection instead.
|
|
||||||
|
|
||||||
You can determine which version of the HTTP protocol was used by examining
|
|
||||||
the `.http_version` property on the response.
|
|
||||||
|
|
||||||
```python
|
|
||||||
client = httpx.AsyncClient(http2=True)
|
|
||||||
response = await client.get(...)
|
|
||||||
print(response.http_version) # "HTTP/1.0", "HTTP/1.1", or "HTTP/2".
|
|
||||||
```

# Logging
|
|
||||||
|
|
||||||
If you need to inspect the internal behaviour of `httpx`, you can use Python's standard logging to output information about the underlying network behaviour.
|
|
||||||
|
|
||||||
For example, the following configuration...
|
|
||||||
|
|
||||||
```python
|
|
||||||
import logging
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
logging.basicConfig(
|
|
||||||
format="%(levelname)s [%(asctime)s] %(name)s - %(message)s",
|
|
||||||
datefmt="%Y-%m-%d %H:%M:%S",
|
|
||||||
level=logging.DEBUG
|
|
||||||
)
|
|
||||||
|
|
||||||
httpx.get("https://www.example.com")
|
|
||||||
```
|
|
||||||
|
|
||||||
Will send debug level output to the console, or wherever `stdout` is directed too...
|
|
||||||
|
|
||||||
```
|
|
||||||

|
||||||
DEBUG [2024-09-28 17:27:41] httpcore.connection - close.complete
|
|
||||||
```
|
|
||||||
|
|
||||||
Logging output includes information from both the high-level `httpx` logger, and the network-level `httpcore` logger, which can be configured separately.
|
|
||||||
|
|
||||||
For handling more complex logging configurations you might want to use the dictionary configuration style...
|
|
||||||
|
|
||||||
```python
|
|
||||||
import logging.config
|
|
||||||
import httpx
|
|
||||||
|
|
||||||
LOGGING_CONFIG = {
|
|
||||||
"version": 1,
|
|
||||||
"handlers": {
|
|
||||||
"default": {
|
|
||||||
"class": "logging.StreamHandler",
|
|
||||||
"formatter": "http",
|
|
||||||
"stream": "ext://sys.stderr"
|
|
||||||
}
|
|
||||||
},
|
|
||||||
"formatters": {
|
|
||||||
"http": {
|
|
||||||
"format": "%(levelname)s [%(asctime)s] %(name)s - %(message)s",
|
|
||||||
"datefmt": "%Y-%m-%d %H:%M:%S",
|
|
||||||
}
|
|
||||||
},
|
|
||||||
'loggers': {
|
|
||||||
'httpx': {
|
|
||||||
'handlers': ['default'],
|
|
||||||
'level': 'DEBUG',
|
|
||||||
},
|
|
||||||
'httpcore': {
|
|
||||||
'handlers': ['default'],
|
|
||||||
'level': 'DEBUG',
|
|
||||||
},
|
|
||||||
}
|
|
||||||
}
|
|
||||||
|
|
||||||
logging.config.dictConfig(LOGGING_CONFIG)
|
|
||||||
httpx.get('https://www.example.com')
|
|
||||||
```
|
|
||||||
|
|
||||||
The exact formatting of the debug logging may be subject to change across different versions of `httpx` and `httpcore`. If you need to rely on a particular format it is recommended that you pin installation of these packages to fixed versions.

# Network Backends
|
||||||
|
|
||||||
|
The lowest level network abstractions in `httpx` are the `NetworkBackend` and `NetworkStream` classes. These provide a consistent interface onto the operations for working with a network stream, typically over a TCP connection. Different runtimes (threaded, trio & asyncio) are supported via alternative implementations of the core interface.
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## `NetworkBackend()`
|
||||||
|
|
||||||
|
The default backend is instantiated via the `NetworkBackend` class...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> net = httpx.NetworkBackend()
|
||||||
|
>>> net
|
||||||
|
<NetworkBackend [threaded]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> net = ahttpx.NetworkBackend()
|
||||||
|
>>> net
|
||||||
|
<NetworkBackend [asyncio]>
|
||||||
|
```
|
||||||
|
|
||||||
|
### `.connect(host, port)`
|
||||||
|
|
||||||
|
A TCP stream is created using the `connect` method...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> net = httpx.NetworkBackend()
|
||||||
|
>>> stream = net.connect("www.encode.io", 80)
|
||||||
|
>>> stream
|
||||||
|
<NetworkStream ["168.0.0.1:80"]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> net = ahttpx.NetworkBackend()
|
||||||
|
>>> stream = await net.connect("www.encode.io", 80)
|
||||||
|
>>> stream
|
||||||
|
<NetworkStream ["168.0.0.1:80"]>
|
||||||
|
```
|
||||||
|
|
||||||
|
Streams support being used in a context managed style. The cleanest approach to resource management is to use `.connect(...)` in the context of a `with` block.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> net = httpx.NetworkBackend()
|
||||||
|
>>> with net.connect("dev.encode.io", 80) as stream:
|
||||||
|
>>> ...
|
||||||
|
>>> stream
|
||||||
|
<NetworkStream ["168.0.0.1:80" CLOSED]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> net = ahttpx.NetworkBackend()
|
||||||
|
>>> async with await net.connect("dev.encode.io", 80) as stream:
|
||||||
|
>>> ...
|
||||||
|
>>> stream
|
||||||
|
<NetworkStream ["168.0.0.1:80" CLOSED]>
|
||||||
|
```
|
||||||
|
|
||||||
|
## `NetworkStream(sock)`
|
||||||
|
|
||||||
|
The `NetworkStream` class provides TCP stream abstraction, by providing a thin wrapper around a socket instance.
|
||||||
|
|
||||||
|
Network streams do not provide any built-in thread or task locking.
|
||||||
|
Within `httpx` thread and task saftey is handled at the `Connection` layer.
|
||||||
|
|
||||||
|
### `.read(max_bytes=None)`
|
||||||
|
|
||||||
|
Read up to `max_bytes` bytes of data from the network stream.
|
||||||
|
If no limit is provided a default value of 64KB will be used.
|
||||||
|
|
||||||
|
### `.write(data)`
|
||||||
|
|
||||||
|
Write the given bytes of `data` to the network stream.
|
||||||
|
|
||||||
|
### `.start_tls(ctx, hostname)`
|
||||||
|
|
||||||
|
Upgrade a stream to TLS (SSL) connection for sending secure `https://` requests.
|
||||||
|
|
||||||
|
`<NetworkStream [“168.0.0.1:443” TLS]>`
|
||||||
|
|
||||||
|
### `.get_extra_info(key)`
|
||||||
|
|
||||||
|
Return information about the underlying resource. May include...
|
||||||
|
|
||||||
|
* `"client_addr"` - Return the client IP and port.
|
||||||
|
* `"server_addr"` - Return the server IP and port.
|
||||||
|
* `"ssl_object"` - Return an `ssl.SSLObject` instance.
|
||||||
|
* `"socket"` - Access the raw socket instance.
|
||||||
|
|
||||||
|
### `.close()`
|
||||||
|
|
||||||
|
Close the network stream. For TLS streams this will attempt to send a closing handshake before terminating the conmection.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> net = httpx.NetworkBackend()
|
||||||
|
>>> stream = net.connect("dev.encode.io", 80)
|
||||||
|
>>> try:
|
||||||
|
>>> ...
|
||||||
|
>>> finally:
|
||||||
|
>>> stream.close()
|
||||||
|
>>> stream
|
||||||
|
<NetworkStream ["168.0.0.1:80" CLOSED]>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> net = ahttpx.NetworkBackend()
|
||||||
|
>>> stream = await net.connect("dev.encode.io", 80)
|
||||||
|
>>> try:
|
||||||
|
>>> ...
|
||||||
|
>>> finally:
|
||||||
|
>>> await stream.close()
|
||||||
|
>>> stream
|
||||||
|
<NetworkStream ["168.0.0.1:80" CLOSED]>
|
||||||
|
```

## Timeouts
|
||||||
|
|
||||||
|
Network timeouts are handled using a context block API.
|
||||||
|
|
||||||
|
This [design approach](https://vorpus.org/blog/timeouts-and-cancellation-for-humans) avoids timeouts needing to passed around throughout the stack, and provides an obvious and natural API to dealing with timeout contexts.
|
||||||
|
|
||||||
|
### timeout(duration)
|
||||||
|
|
||||||
|
The timeout context manager can be used to wrap socket operations anywhere in the stack.
|
||||||
|
|
||||||
|
Here's an example of enforcing an overall 3 second timeout on a request.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> with httpx.Client() as cli:
|
||||||
|
>>> with httpx.timeout(3.0):
|
||||||
|
>>> res = cli.get('https://www.example.com')
|
||||||
|
>>> print(res)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> async with ahttpx.Client() as cli:
|
||||||
|
>>> async with ahttpx.timeout(3.0):
|
||||||
|
>>> res = await cli.get('https://www.example.com')
|
||||||
|
>>> print(res)
|
||||||
|
```
|
||||||
|
|
||||||
|
Timeout contexts provide an API allowing for deadlines to be cancelled.
|
||||||
|
|
||||||
|
### .cancel()
|
||||||
|
|
||||||
|
In this example we enforce a 3 second timeout on *receiving the start of* a streaming HTTP response...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> with httpx.Client() as cli:
|
||||||
|
>>> with httpx.timeout(3.0) as t:
|
||||||
|
>>> with cli.stream('https://www.example.com') as r:
|
||||||
|
>>> t.cancel()
|
||||||
|
>>> print(">>>", res)
|
||||||
|
>>> for chunk in r.stream:
|
||||||
|
>>> print("...", chunk)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> async with ahttpx.Client() as cli:
|
||||||
|
>>> async with ahttpx.timeout(3.0) as t:
|
||||||
|
>>> async with await cli.stream('https://www.example.com') as r:
|
||||||
|
>>> t.cancel()
|
||||||
|
>>> print(">>>", res)
|
||||||
|
>>> async for chunk in r.stream:
|
||||||
|
>>> print("...", chunk)
|
||||||
|
```
|
||||||
|
|
||||||

||||||
|
## Sending HTTP requests
|
||||||
|
|
||||||
|
Let's take a look at how we can work directly with a network backend to send an HTTP request, and recieve an HTTP response.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
import httpx
|
||||||
|
import ssl
|
||||||
|
import truststore
|
||||||
|
|
||||||
|
net = httpx.NetworkBackend()
|
||||||
|
ctx = truststore.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
|
||||||
|
req = b'\r\n'.join([
|
||||||
|
b'GET / HTTP/1.1',
|
||||||
|
b'Host: www.example.com',
|
||||||
|
b'User-Agent: python/dev',
|
||||||
|
b'Connection: close',
|
||||||
|
b'',
|
||||||
|
b'',
|
||||||
|
])
|
||||||
|
|
||||||
|
# Use a 10 second overall timeout for the entire request/response.
|
||||||
|
with httpx.timeout(10.0):
|
||||||
|
# Use a 3 second timeout for the initial connection.
|
||||||
|
with httpx.timeout(3.0) as t:
|
||||||
|
# Open the connection & establish SSL.
|
||||||
|
with net.connect("www.example.com", 443) as stream:
|
||||||
|
stream.start_tls(ctx, hostname="www.example.com")
|
||||||
|
t.cancel()
|
||||||
|
# Send the request & read the response.
|
||||||
|

|

|
buffer.append(part)
|
||||||
|
resp = b''.join(buffer)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
import ahttpx
|
||||||
|

|
||||||
|

|
||||||
|
|

net = ahttpx.NetworkBackend()
|
||||||
|
ctx = truststore.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
|
||||||
|
req = b'\r\n'.join([
|
||||||
|
b'GET / HTTP/1.1',
|
||||||
|
b'Host: www.example.com',
|
||||||
|
b'User-Agent: python/dev',
|
||||||
|
b'Connection: close',

|
||||||
|
|

|
# Use a 10 second overall timeout for the entire request/response.
|
||||||
|
async with ahttpx.timeout(10.0):
|
||||||
|
# Use a 3 second timeout for the initial connection.
|
||||||
|
async with ahttpx.timeout(3.0) as t:
|
||||||
|
# Open the connection & establish SSL.
|
||||||
|
async with await net.connect("www.example.com", 443) as stream:
|
||||||
|
await stream.start_tls(ctx, hostname="www.example.com")
|
||||||
|
t.cancel()
|
||||||
|
# Send the request & read the response.
|
||||||
|
await stream.write(req)
|
||||||
|
buffer = []
|

|
while part := await stream.read():
|
||||||
|
buffer.append(part)
|
||||||
|
resp = b''.join(buffer)
|
||||||
|
```
|
||||||
|
|
||||||
|
The example above is somewhat contrived, there's no HTTP parsing implemented so we can't actually determine when the response is complete. We're using a `Connection: close` header to request that the server close the connection once the response is complete.
|
||||||
|
|
||||||
|
A more complete example would require proper HTTP parsing. The `Connection` class implements an HTTP request/response interface, layered over a `NetworkStream`.

## Custom network backends
|
||||||
|
|
||||||
|
The interface for implementing custom network backends is provided by two classes...
|
||||||
|
|
||||||
|
### `NetworkBackendInterface`
|
||||||
|
|
||||||
|
The abstract interface implemented by `NetworkBackend`. See above for details.
|
||||||
|
|
||||||
|
### `NetworkStreamInterface`
|
||||||
|
|
||||||
|
The abstract interface implemented by `NetworkStream`. See above for details.
|
||||||
|
|
||||||
|
### An example backend
|
||||||
|
|
||||||
|
We can use these interfaces to implement custom functionality. For example, here we're providing a network backend that logs all the ingoing and outgoing bytes.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
class RecordingBackend(httpx.NetworkBackendInterface):
|
||||||
|
def __init__(self):
|
||||||
|
self._backend = NetworkBackend()
|
||||||
|
|
||||||
|
def connect(self, host, port):
|
||||||
|
# Delegate creating connections to the default
|
||||||
|
# network backend, and return a wrapped stream.
|
||||||
|
stream = self._backend.connect(host, port)
|
||||||
|
return RecordingStream(stream)
|
||||||
|
|
||||||
|
|
||||||
|
class RecordingStream(httpx.NetworkStreamInterface):
|
||||||
|
def __init__(self, stream):
|
||||||
|
self._stream = stream
|
||||||
|
|
||||||
|
def read(self, max_bytes: int = None):
|
||||||
|
# Print all incoming data to the terminal.
|
||||||
|
data = self._stream.read(max_bytes)
|
||||||
|
lines = data.decode('ascii', errors='replace').splitlines()
|
||||||
|
for line in lines:
|
||||||
|
print("<<< ", line)
|
||||||
|
return data
|
||||||
|
|
||||||
|
def write(self, data):
|
||||||
|
# Print all outgoing data to the terminal.
|
||||||
|
lines = data.decode('ascii', errors='replace').splitlines()
|
||||||
|
for line in lines:
|
||||||
|
print(">>> ", line)
|
||||||
|
self._stream.write(data)
|
||||||
|
|
||||||
|
def start_tls(ctx, hostname):
|
||||||
|
self._stream.start_tls(ctx, hostname)
|
||||||
|
|
||||||
|
def get_extra_info(key):
|
||||||
|
return self._stream.get_extra_info(key)
|
||||||
|
|
||||||
|
def close():
|
||||||
|
self._stream.close()
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
class RecordingBackend(ahhtpx.NetworkBackendInterface):
|
||||||
|
def __init__(self):
|
||||||
|
self._backend = NetworkBackend()
|
||||||
|
|
||||||
|
async def connect(self, host, port):
|
||||||
|
# Delegate creating connections to the default
|
||||||
|
# network backend, and return a wrapped stream.
|
||||||
|
stream = await self._backend.connect(host, port)
|
||||||
|
return RecordingStream(stream)
|
||||||
|
|
||||||
|
|
||||||
|
class RecordingStream(ahttpx.NetworkStreamInterface):
|
||||||
|
def __init__(self, stream):
|
||||||
|
self._stream = stream
|
||||||
|
|
||||||
|
async def read(self, max_bytes: int = None):
|
||||||
|
# Print all incoming data to the terminal.
|
||||||
|
data = await self._stream.read(max_bytes)
|
||||||
|
lines = data.decode('ascii', errors='replace').splitlines()
|
||||||
|
for line in lines:
|
||||||
|
print("<<< ", line)
|
||||||
|
return data
|
||||||
|
|
||||||
|
async def write(self, data):
|
||||||
|
# Print all outgoing data to the terminal.
|
||||||
|
lines = data.decode('ascii', errors='replace').splitlines()
|
||||||
|
for line in lines:
|
||||||
|
print(">>> ", line)
|
||||||
|
await self._stream.write(data)
|
||||||
|
|
||||||
|
async def start_tls(ctx, hostname):
|
||||||
|
await self._stream.start_tls(ctx, hostname)
|
||||||
|
|
||||||
|
def get_extra_info(key):
|
||||||
|
return self._stream.get_extra_info(key)
|
||||||
|
|
||||||
|
async def close():
|
||||||
|
await self._stream.close()
|
||||||
|
```
|
||||||
|
|
||||||
|
We can now instantiate a client using this network backend.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> transport = httpx.ConnectionPool(backend=RecordingBackend())
|
||||||
|
>>> cli = httpx.Client(transport=transport)
|
||||||
|
>>> cli.get('https://www.example.com')
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> transport = ahttpx.ConnectionPool(backend=RecordingBackend())
|
||||||
|
>>> cli = ahttpx.Client(transport=transport)
|
||||||
|
>>> await cli.get('https://www.example.com')
|
||||||
|
```
|
||||||
|
|
||||||
|
Custom network backends can also be used to provide functionality such as handling DNS caching for name lookups, or connecting via a UNIX domain socket instead of a TCP connection.

First, start by importing HTTPX:
|
Install using ...
|
||||||
|
|
||||||
```pycon
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .shell .httpx }
|
||||||
|
$ pip install --pre httpx
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .shell .ahttpx .hidden }
|
||||||
|
$ pip install --pre ahttpx
|
||||||
|
```
|
||||||
|
|
||||||
|
First, start by importing `httpx`...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
>>> import httpx
|
>>> import httpx
|
||||||
```
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> import ahttpx
|
||||||
|
```
|
||||||
|
|
||||||
Now, let’s try to get a webpage.
|
Now, let’s try to get a webpage.
|
||||||
|
|
||||||
```pycon
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
>>> r = httpx.get('https://httpbin.org/get')
|
>>> r = httpx.get('https://httpbin.org/get')
|
||||||
>>> r
|
>>> r
|
||||||
<Response [200 OK]>
|
<Response [200 OK]>
|
||||||
```
|
```
|
||||||
|
|
||||||
Similarly, to make an HTTP POST request:
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> r = await ahttpx.get('https://httpbin.org/get')
|
||||||
```pycon
|
>>> r
|
||||||
>>> r = httpx.post('https://httpbin.org/post', data={'key': 'value'})
|
<Response [200 OK]>
|
||||||
```
|
```
|
||||||
|
|
||||||
The PUT, DELETE, HEAD, and OPTIONS requests all follow the same style:
|
To make an HTTP `POST` request, including some content...
|
||||||
|
|
||||||
```pycon
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
>>> r = httpx.put('https://httpbin.org/put', data={'key': 'value'})
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> form = httpx.Form({'key': 'value'})
|
||||||
|
>>> r = httpx.post('https://httpbin.org/post', content=form)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> form = httpx.Form({'key': 'value'})
|
||||||
|
>>> r = await ahttpx.post('https://httpbin.org/post', content=form)
|
||||||
|
```
|
||||||
|
|
||||||
|
Shortcut methods for `PUT`, `PATCH`, and `DELETE` requests follow the same style...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> r = httpx.put('https://httpbin.org/put', content=form)
|
||||||
|
>>> r = httpx.patch('https://httpbin.org/patch', content=form)
|
||||||
>>> r = httpx.delete('https://httpbin.org/delete')
|
>>> r = httpx.delete('https://httpbin.org/delete')
|
||||||
>>> r = httpx.head('https://httpbin.org/get')
|
```
|
||||||
>>> r = httpx.options('https://httpbin.org/get')
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> r = await ahttpx.put('https://httpbin.org/put', content=form)
|

To include URL query parameters in the request, construct a URL using the `params` keyword...

```pycon

To see how the values get encoding into the URL string, we can inspect the

resulting URL that was used to make the request:

|
'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'
|
||||||
```
|
```
|
||||||
|
|
||||||
You can inspect what encoding will be used to decode the response.
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> r = await ahttpx.get('https://www.example.org/')
|
||||||
```pycon
|
|
||||||
>>> r.encoding
|
|
||||||
'UTF-8'
|
|
||||||
```
|
|
||||||
|
|
||||||
In some cases the response may not contain an explicit encoding, in which case HTTPX
|
|
||||||
will attempt to automatically determine an encoding to use.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> r.encoding
|
|
||||||
None
|
|
||||||
>>> r.text
|
>>> r.text
|
||||||
'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'
|
'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'
|
||||||
```
|
```
|
||||||
|
|
||||||
If you need to override the standard behaviour and explicitly set the encoding to
|
|
||||||
use, then you can do that too.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> r.encoding = 'ISO-8859-1'
|
|
||||||
```

```
|
||||||
|
|
||||||
Any `gzip` and `deflate` HTTP response encodings will automatically
|
```{ .python .ahttpx .hidden }
|
||||||
be decoded for you. If `brotlipy` is installed, then the `brotli` response
|
>>> r.body
|
||||||
encoding will be supported. If `zstandard` is installed, then `zstd`
|
b'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'
|
||||||
response encodings will also be supported.
|
|
||||||
|
|
||||||
For example, to create an image from binary data returned by a request, you can use the following code:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> from PIL import Image
|
|
||||||
>>> from io import BytesIO
|

|
We can inspect the HTTP status code of the response:
|
||||||
|
|
||||||
```pycon
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
>>> r = httpx.get('https://httpbin.org/get')
|
>>> r = httpx.get('https://httpbin.org/get')
|
||||||
>>> r.status_code
|
>>> r.status_code
|
||||||
200
|
200
|
||||||
```
|
```
|
||||||
|
|
||||||
HTTPX also includes an easy shortcut for accessing status codes by their text phrase.
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> r = await ahttpx.get('https://httpbin.org/get')
|
||||||
```pycon
|
>>> r.status_code
|
||||||
>>> r.status_code == httpx.codes.OK
|
200
|
||||||
True
|
|
||||||
```
|
|
||||||
|
|
||||||
We can raise an exception for any responses which are not a 2xx success code:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> not_found = httpx.get('https://httpbin.org/status/404')
|
|
||||||
>>> not_found.status_code
|
|
||||||
404
|
|
||||||
>>> not_found.raise_for_status()
|
|
||||||
Traceback (most recent call last):
|
|
||||||
File "/Users/tomchristie/GitHub/encode/httpcore/httpx/models.py", line 837, in raise_for_status
|
|
||||||
raise HTTPStatusError(message, response=self)
|
|
||||||
httpx._exceptions.HTTPStatusError: 404 Client Error: Not Found for url: https://httpbin.org/status/404
|
|
||||||
For more information check: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/404
|
|
||||||
```
|
|
||||||
|
|
||||||
Any successful response codes will return the `Response` instance rather than raising an exception.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> r.raise_for_status()
|
|
||||||
```
|
|
||||||
|
|
||||||
The method returns the response instance, allowing you to use it inline. For example:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> r = httpx.get('...').raise_for_status()
|
|
||||||
>>> data = httpx.get('...').raise_for_status().json()
|

```

|
```
|
||||||
|
|
||||||
Or stream the text, on a line-by-line basis...
|
---
|
||||||
|
|
||||||
```pycon
|
<span class="link-prev">← [Home](index.md)</span>
|
||||||
>>> with httpx.stream("GET", "https://www.example.com") as r:
|
<span class="link-next">[Clients](clients.md) →</span>
|
||||||
... for line in r.iter_lines():
|
<span> </span>
|
||||||
... print(line)
|
|
||||||
```
|
|
||||||
|
|
||||||
HTTPX will use universal line endings, normalising all cases to `\n`.
|
|
||||||
|
|
||||||
In some cases you might want to access the raw bytes on the response without applying any HTTP content decoding. In this case any content encoding that the web server has applied such as `gzip`, `deflate`, `brotli`, or `zstd` will
|
|
||||||
not be automatically decoded.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with httpx.stream("GET", "https://www.example.com") as r:
|
|
||||||
... for chunk in r.iter_raw():
|
|
||||||
... print(chunk)
|
|
||||||
```
|
|
||||||
|
|
||||||
If you're using streaming responses in any of these ways then the `response.content` and `response.text` attributes will not be available, and will raise errors if accessed. However you can also use the response streaming functionality to conditionally load the response body:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> with httpx.stream("GET", "https://www.example.com") as r:
|
|
||||||
... if int(r.headers['Content-Length']) < TOO_LONG:
|
|
||||||
... r.read()
|
|
||||||
... print(r.text)
|
|
||||||
```
|
|
||||||
|
|
||||||
## Cookies
|
|
||||||
|
|
||||||
Any cookies that are set on the response can be easily accessed:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> r = httpx.get('https://httpbin.org/cookies/set?chocolate=chip')
|
|
||||||
>>> r.cookies['chocolate']
|
|
||||||
'chip'
|
|
||||||
```
|
|
||||||
|
|
||||||
To include cookies in an outgoing request, use the `cookies` parameter:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> cookies = {"peanut": "butter"}
|
|
||||||
>>> r = httpx.get('https://httpbin.org/cookies', cookies=cookies)
|
|
||||||
>>> r.json()
|
|
||||||
{'cookies': {'peanut': 'butter'}}
|
|
||||||
```
|
|
||||||
|
|
||||||
Cookies are returned in a `Cookies` instance, which is a dict-like data structure
|
|
||||||
with additional API for accessing cookies by their domain or path.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> cookies = httpx.Cookies()
|
|
||||||
>>> cookies.set('cookie_on_domain', 'hello, there!', domain='httpbin.org')
|
|
||||||
>>> cookies.set('cookie_off_domain', 'nope.', domain='example.org')
|
|
||||||
>>> r = httpx.get('http://httpbin.org/cookies', cookies=cookies)
|
|
||||||
>>> r.json()
|
|
||||||
{'cookies': {'cookie_on_domain': 'hello, there!'}}
|
|
||||||
```
|
|
||||||
|
|
||||||
## Redirection and History
|
|
||||||
|
|
||||||
By default, HTTPX will **not** follow redirects for all HTTP methods, although
|
|
||||||
this can be explicitly enabled.
|
|
||||||
|
|
||||||
For example, GitHub redirects all HTTP requests to HTTPS.
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> r = httpx.get('http://github.com/')
|
|
||||||
>>> r.status_code
|
|
||||||
301
|
|
||||||
>>> r.history
|
|
||||||
[]
|
|
||||||
>>> r.next_request
|
|
||||||
<Request('GET', 'https://github.com/')>
|
|
||||||
```
|
|
||||||
|
|
||||||
You can modify the default redirection handling with the `follow_redirects` parameter:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> r = httpx.get('http://github.com/', follow_redirects=True)
|
|
||||||
>>> r.url
|
|
||||||
URL('https://github.com/')
|
|
||||||
>>> r.status_code
|
|
||||||
200
|
|
||||||
>>> r.history
|
|
||||||
[<Response [301 Moved Permanently]>]
|
|
||||||
```
|
|
||||||
|
|
||||||
The `history` property of the response can be used to inspect any followed redirects.
|
|
||||||
It contains a list of any redirect responses that were followed, in the order
|
|
||||||
in which they were made.
|
|
||||||
|
|
||||||
## Timeouts
|
|
||||||
|
|
||||||
HTTPX defaults to including reasonable timeouts for all network operations,
|
|
||||||
meaning that if a connection is not properly established then it should always
|
|
||||||
raise an error rather than hanging indefinitely.
|
|
||||||
|
|
||||||
The default timeout for network inactivity is five seconds. You can modify the
|
|
||||||
value to be more or less strict:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> httpx.get('https://github.com/', timeout=0.001)
|
|
||||||
```
|
|
||||||
|
|
||||||
You can also disable the timeout behavior completely...
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> httpx.get('https://github.com/', timeout=None)
|
|
||||||
```
|
|
||||||
|
|
||||||
For advanced timeout management, see [Timeout fine-tuning](advanced/timeouts.md#fine-tuning-the-configuration).
|
|
||||||
|
|
||||||
## Authentication
|
|
||||||
|
|
||||||
HTTPX supports Basic and Digest HTTP authentication.
|
|
||||||
|
|
||||||
To provide Basic authentication credentials, pass a 2-tuple of
|
|
||||||
plaintext `str` or `bytes` objects as the `auth` argument to the request
|
|
||||||
functions:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> httpx.get("https://example.com", auth=("my_user", "password123"))
|
|
||||||
```
|
|
||||||
|
|
||||||
To provide credentials for Digest authentication you'll need to instantiate
|
|
||||||
a `DigestAuth` object with the plaintext username and password as arguments.
|
|
||||||
This object can be then passed as the `auth` argument to the request methods
|
|
||||||
as above:
|
|
||||||
|
|
||||||
```pycon
|
|
||||||
>>> auth = httpx.DigestAuth("my_user", "password123")
|
|
||||||
>>> httpx.get("https://example.com", auth=auth)
|
|
||||||
<Response [200 OK]>
|
|
||||||
```
|
|
||||||
|
|
||||||
## Exceptions
|
|
||||||
|
|
||||||
HTTPX will raise exceptions if an error occurs.
|
|
||||||
|
|
||||||
The most important exception classes in HTTPX are `RequestError` and `HTTPStatusError`.
|
|
||||||
|
|
||||||
The `RequestError` class is a superclass that encompasses any exception that occurs
|
|
||||||
while issuing an HTTP request. These exceptions include a `.request` attribute.
|
|
||||||
|
|
||||||
```python
|
|
||||||
try:
|
|
||||||
response = httpx.get("https://www.example.com/")
|
|
||||||
except httpx.RequestError as exc:
|
|
||||||
print(f"An error occurred while requesting {exc.request.url!r}.")
|
|
||||||
```
|
|
||||||
|
|
||||||
The `HTTPStatusError` class is raised by `response.raise_for_status()` on responses which are not a 2xx success code.
|
|
||||||
These exceptions include both a `.request` and a `.response` attribute.
|
|
||||||
|
|
||||||
```python
|
|
||||||
response = httpx.get("https://www.example.com/")
|
|
||||||
try:
|
|
||||||
response.raise_for_status()
|
|
||||||
except httpx.HTTPStatusError as exc:
|
|
||||||
print(f"Error response {exc.response.status_code} while requesting {exc.request.url!r}.")
|
|
||||||
```
|
|
||||||
|
|
||||||
There is also a base class `HTTPError` that includes both of these categories, and can be used
|
|
||||||
to catch either failed requests, or 4xx and 5xx responses.
|
|
||||||
|
|
||||||
You can either use this base class to catch both categories...
|
|
||||||
|
|
||||||
```python
|
|
||||||
try:
|
|
||||||
response = httpx.get("https://www.example.com/")
|
|
||||||
response.raise_for_status()
|
|
||||||
except httpx.HTTPError as exc:
|
|
||||||
print(f"Error while requesting {exc.request.url!r}.")
|
|
||||||
```
|
|
||||||
|
|
||||||
Or handle each case explicitly...
|
|
||||||
|
|
||||||
```python
|
|
||||||
try:
|
|
||||||
response = httpx.get("https://www.example.com/")
|
|
||||||
response.raise_for_status()
|
|
||||||
except httpx.RequestError as exc:
|
|
||||||
print(f"An error occurred while requesting {exc.request.url!r}.")
|
|
||||||
except httpx.HTTPStatusError as exc:
|
|
||||||
print(f"Error response {exc.response.status_code} while requesting {exc.request.url!r}.")
|
|
||||||
```
|
|
||||||
|
|
||||||

# Requests
|
||||||
|
|
||||||
|
The core elements of an HTTP request are the `method`, `url`, `headers` and `body`.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> req = httpx.Request('GET', 'https://www.example.com/')
|
||||||
|
>>> req
|
||||||
|
<Request [GET 'https://www.example.com/']>
|
||||||
|
>>> req.method
|
||||||
|
'GET'
|
||||||
|
>>> req.url
|
||||||
|
<URL 'https://www.example.com/'>
|
||||||
|
>>> req.headers
|
||||||
|
<Headers {'Host': 'www.example.com'}>
|
||||||
|
>>> req.body
|
||||||
|
b''
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> req = ahttpx.Request('GET', 'https://www.example.com/')
|
||||||
|
>>> req
|
||||||
|
<Request [GET 'https://www.example.com/']>
|
||||||
|
>>> req.method
|
||||||
|
'GET'
|
||||||
|
>>> req.url
|
||||||
|
<URL 'https://www.example.com/'>
|
||||||
|
>>> req.headers
|
||||||
|
<Headers {'Host': 'www.example.com'}>
|
||||||
|
>>> req.body
|
||||||
|
b''
|
||||||
|
```
|
||||||
|
|
||||||
|
## Working with the request headers
|
||||||
|
|
||||||
|
The following headers have automatic behavior with `Requests` instances...
|
||||||
|
|
||||||
|
* `Host` - A `Host` header must always be included on a request. This header is automatically populated from the `url`, using the `url.netloc` property.
|
||||||
|
* `Content-Length` - Requests including a request body must always include either a `Content-Length` header or a `Transfer-Encoding: chunked` header. This header is automatically populated if `content` is not `None` and the content is a known size.
|
||||||
|
* `Transfer-Encoding` - Requests automatically include a `Transfer-Encoding: chunked` header if `content` is not `None` and the content is an unkwown size.
|
||||||
|
* `Content-Type` - Requests automatically include a `Content-Type` header if `content` is set using the [Content Type] API.

||||||
|
|
||||||
|

# Responses
|
||||||
|
|
||||||
|
The core elements of an HTTP response are the `status_code`, `headers` and `body`.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> resp = httpx.Response(200, headers={'Content-Type': 'text/plain'}, content=b'hello, world')
|
||||||
|
>>> resp
|
||||||
|
<Response [200 OK]>
|
||||||
|
>>> resp.status_code
|
||||||
|
200
|
||||||
|
>>> resp.headers
|
||||||
|
<Headers {'Content-Type': 'text/html'}>
|
||||||
|
>>> resp.body
|
||||||
|
b'hello, world'
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> resp = ahttpx.Response(200, headers={'Content-Type': 'text/plain'}, content=b'hello, world')
|
||||||
|
>>> resp
|
||||||
|
<Response [200 OK]>
|
||||||
|
>>> resp.status_code
|
||||||
|
200
|
||||||
|
>>> resp.headers
|
||||||
|
<Headers {'Content-Type': 'text/html'}>
|
||||||
|
>>> resp.body
|
||||||
|
b'hello, world'
|
||||||
|
```
|
||||||
|
|
||||||
|
## Working with the response headers
|
||||||
|
|
||||||
|
The following headers have automatic behavior with `Response` instances...
|
||||||
|
|
||||||
|
* `Content-Length` - Responses including a response body must always include either a `Content-Length` header or a `Transfer-Encoding: chunked` header. This header is automatically populated if `content` is not `None` and the content is a known size.
|
||||||
|
* `Transfer-Encoding` - Responses automatically include a `Transfer-Encoding: chunked` header if `content` is not `None` and the content is an unkwown size.
|
||||||
|
* `Content-Type` - Responses automatically include a `Content-Type` header if `content` is set using the [Content Type] API.
|
||||||
|
|
||||||
|
## Working with content types
|
||||||
|
|
||||||
|
Including HTML content...

|
```{ .python .httpx }
|
||||||
|
>>> content = httpx.HTML('<html><head>...</head><body>...</body></html>')
|
||||||
|
>>> response = httpx.Response(200, content=content)
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|

The HTTP server provides a simple request/response API.
|

This gives you a lightweight way to build web applications or APIs.

# Streams
|
||||||
|
|
||||||
|
Streams provide a minimal file-like interface for reading bytes from a data source. They are used as the abstraction for reading the body of a request or response.
|
||||||
|
|
||||||
|
The interfaces here are simplified versions of Python's standard I/O operations.
|
||||||
|
|
||||||
|
## Stream
|
||||||
|
|
||||||
|
The base `Stream` class. The core of the interface is a subset of Python's `io.IOBase`...
|
||||||
|
|
||||||
|
* `.read(size=-1)` - *(bytes)* Return the bytes from the data stream. If the `size` argument is omitted or negative then the entire stream will be read. If `size` is an positive integer then the call returns at most `size` bytes. A return value of `b''` indicates the end of the stream has been reached.
|
||||||
|
* `.write(self, data: bytes)` - *None* Write the given bytes to the data stream. May raise `NotImplmentedError` if this is not a writeable stream.
|
||||||
|
* `.close()` - Close the stream. Any further operations will raise a `ValueError`.
|
||||||
|
|
||||||
|
Additionally, the following property is also defined...
|
||||||
|
|
||||||
|
* `.size` - *(int or None)* Return an integer indicating the size of the stream, or `None` if the size is unknown. When working with HTTP this is used to either set a `Content-Length: <size>` header, or a `Content-Encoding: chunked` header.
|
||||||
|
|
||||||
|
The `Stream` interface and `ContentType` interface are related, with streams being used as the abstraction for the bytewise representation, and content types being used to encapsulate the parsed data structure.
|
||||||
|
|
||||||
|
For example, encoding some `JSON` data...
|
||||||
|
|
||||||
|
```python
|
||||||
|
>>> data = httpx.JSON({'name': 'zelda', 'score': '478'})
|
||||||
|
>>> stream = data.encode()
|
||||||
|
>>> stream.read()
|
||||||
|
b'{"name":"zelda","score":"478"}'
|
||||||
|
>>> stream.content_type
|
||||||
|
'application/json'
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## ByteStream
|
||||||
|
|
||||||
|
A byte stream returning fixed byte content. Similar to Python's `io.BytesIO` class.
|
||||||
|
|
||||||
|
```python
|
||||||
|
>>> s = httpx.ByteStream(b'{"msg": "Hello, world!"}')
|
||||||
|
>>> s.read()
|
||||||
|
b'{"msg": "Hello, world!"}'
|
||||||
|
```
|
||||||
|
|
||||||
|
## FileStream
|
||||||
|
|
||||||
|
A byte stream returning content from a file.
|
||||||
|
|
||||||
|
The standard pattern for instantiating a `FileStream` is to use `File` as a context manager:
|
||||||
|
|
||||||
|
```python
|
||||||
|
>>> with httpx.File('upload.json') as s:
|
||||||
|
... s.read()
|
||||||
|
b'{"msg": "Hello, world!"}'
|
||||||
|
```
|
||||||
|
|
||||||
|
## MultiPartStream
|
||||||
|
|
||||||
|
A byte stream returning multipart upload data.
|
||||||
|
|
||||||
|
The standard pattern for instantiating a `MultiPartStream` is to use `MultiPart` as a context manager:
|
||||||
|
|
||||||
|
```python
|
||||||
|
>>> files = {'avatar-upload': 'image.png'}
|
||||||
|
>>> with httpx.MultiPart(files=files) as s:
|
||||||
|
... s.read()
|
||||||
|
# ...
|
||||||
|
```
|
||||||
|
|
||||||
|
## HTTPStream
|
||||||
|
|
||||||
|
A byte stream returning unparsed content from an HTTP request or response.
|
||||||
|
|
||||||
|
```python
|
||||||
|
>>> with httpx.Client() as cli:
|
||||||
|
... r = cli.get('https://www.example.com/')
|
||||||
|
... r.stream.read()
|
||||||
|
# ...
|
||||||
|
```
|
||||||
|
|
||||||
|
## GZipStream
|
||||||
|
|
||||||
|
...
|
||||||
|
|

# Troubleshooting
|
|
||||||
|
|
||||||
This page lists some common problems or issues you could encounter while developing with HTTPX, as well as possible solutions.
|
|
||||||
|
|
||||||
## Proxies
|
|
||||||
|
|
||||||
---
|
|
||||||
|
|
||||||
### "`The handshake operation timed out`" on HTTPS requests when using a proxy
|
|
||||||
|
|
||||||
**Description**: When using a proxy and making an HTTPS request, you see an exception looking like this:
|
|
||||||
|
|
||||||
```console
|
|
||||||
httpx.ProxyError: _ssl.c:1091: The handshake operation timed out
|
|
||||||
```
|
|
||||||
|
|
||||||
**Similar issues**: [encode/httpx#1412](https://github.com/encode/httpx/issues/1412), [encode/httpx#1433](https://github.com/encode/httpx/issues/1433)
|
|
||||||
|
|
||||||
**Resolution**: it is likely that you've set up your proxies like this...
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"http://": httpx.HTTPTransport(proxy="http://myproxy.org"),
|
|
||||||
"https://": httpx.HTTPTransport(proxy="https://myproxy.org"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Using this setup, you're telling HTTPX to connect to the proxy using HTTP for HTTP requests, and using HTTPS for HTTPS requests.
|
|
||||||
|
|
||||||
But if you get the error above, it is likely that your proxy doesn't support connecting via HTTPS. Don't worry: that's a [common gotcha](advanced/proxies.md#http-proxies).
|
|
||||||
|
|
||||||
Change the scheme of your HTTPS proxy to `http://...` instead of `https://...`:
|
|
||||||
|
|
||||||
```python
|
|
||||||
mounts = {
|
|
||||||
"http://": httpx.HTTPTransport(proxy="http://myproxy.org"),
|
|
||||||
"https://": httpx.HTTPTransport(proxy="http://myproxy.org"),
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
This can be simplified to:
|
|
||||||
|
|
||||||
```python
|
|
||||||
proxy = "http://myproxy.org"
|
|
||||||
with httpx.Client(proxy=proxy) as client:
|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
For more information, see [Proxies: FORWARD vs TUNNEL](advanced/proxies.md#forward-vs-tunnel).
|
|
||||||
|
|
||||||

|
|
||||||
|
|
||||||
### Error when making requests to an HTTPS proxy
|
|
||||||
|
|
||||||
**Description**: your proxy _does_ support connecting via HTTPS, but you are seeing errors along the lines of...
|
|
||||||
|
|
||||||
```console
|
|
||||||
httpx.ProxyError: [SSL: PRE_MAC_LENGTH_TOO_LONG] invalid alert (_ssl.c:1091)
|
|
||||||
```
|
|
||||||
|
|
||||||
**Similar issues**: [encode/httpx#1424](https://github.com/encode/httpx/issues/1424).
|
|
||||||
|
|
||||||
**Resolution**: HTTPX does not properly support HTTPS proxies at this time. If that's something you're interested in having, please see [encode/httpx#1434](https://github.com/encode/httpx/issues/1434) and consider lending a hand there.

# URLs
|
||||||
|
|
||||||
|
The `URL` class handles URL validation and parsing.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> url = httpx.URL('https://www.example.com/')
|
||||||
|
>>> url
|
||||||
|
<URL 'https://www.example.com/'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> url = ahttpx.URL('https://www.example.com/')
|
||||||
|
>>> url
|
||||||
|
<URL 'https://www.example.com/'>
|
||||||
|
```
|
||||||
|
|
||||||
|
URL components are normalised, following the same rules as internet browsers.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> url = httpx.URL('https://www.EXAMPLE.com:443/path/../main')
|
||||||
|
>>> url
|
||||||
|
<URL 'https://www.example.com/main'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> url = ahttpx.URL('https://www.EXAMPLE.com:443/path/../main')
|
||||||
|
>>> url
|
||||||
|
<URL 'https://www.example.com/main'>
|
||||||
|
```
|
||||||
|
|
||||||
|
Both absolute and relative URLs are valid.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> url = httpx.URL('/README.md')
|
||||||
|
>>> url
|
||||||
|
<URL '/README.md'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> url = ahttpx.URL('/README.md')
|
||||||
|
>>> url
|
||||||
|
<URL '/README.md'>
|
||||||
|
```
|
||||||
|
|
||||||
|
Coercing a URL to a `str` will always result in a printable ASCII string.
|
||||||

### URL components
|
||||||
|
|
||||||
|
The following properties are available for accessing the component parts of a URL.
|
||||||
|
|
||||||
|
* `.scheme` - *str. ASCII. Normalised to lowercase.*
|
||||||
|
* `.userinfo` - *str. ASCII. URL encoded.*
|
||||||
|
* `.username` - *str. Unicode.*
|
||||||
|
* `.password` - *str. Unicode.*
|
||||||
|
* `.host` - *str. ASCII. IDNA encoded.*
|
||||||
|
* `.port` - *int or None. Scheme default ports are normalised to None.*
|
||||||
|
* `.authority` - *str. ASCII. IDNA encoded. Eg. "example.com", "example.com:1337", "xn--p1ai".*
|
||||||
|
* `.path` - *str. Unicode.*
|
||||||
|
* `.query` - *str. ASCII. URL encoded.*
|
||||||
|
* `.target` - *str. ASCII. URL encoded.*
|
||||||
|
* `.fragment` - *str. ASCII. URL encoded.*
|
||||||
|
|
||||||
|
A parsed representation of the query parameters is accessible with the `.params` property.
|
||||||
|
|
||||||
|
* `.params` - [`QueryParams`](#query-parameters)
|
||||||
|
|
||||||
|
URLs can be instantiated from their components...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> httpx.URL(scheme="https", host="example.com", path="/")
|
||||||
|
<URL 'https://example.com/'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> ahttpx.URL(scheme="https", host="example.com", path="/")
|
||||||
|
<URL 'https://example.com/'>
|
||||||
|
```
|
||||||
|
|
||||||
|
Or using both the string form and query parameters...
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> httpx.URL("https://example.com/", params={"search": "some text"})
|
||||||
|
<URL 'https://example.com/?search=some+text'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> ahttpx.URL("https://example.com/", params={"search": "some text"})
|
||||||
|
<URL 'https://example.com/?search=some+text'>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Modifying URLs
|
||||||
|
|
||||||
|
Instances of `URL` are immutable, meaning their value cannot be changed. Instead new modified instances may be created.
|
||||||
|
|
||||||
|
* `.copy_with(**components)` - *Return a new URL, updating one or more components. Eg. `url = url.copy_with(scheme="https")`*.
|
||||||
|
* `.copy_set_param(key, value)` - *Return a new URL, setting a query parameter. Eg. `url = url.copy_set_param("sort_by", "price")`*.
|
||||||
|
* `.copy_append_param(key, value)` - *Return a new URL, setting or appending a query parameter. Eg. `url = url.copy_append_param("tag", "sale")`*.
|
||||||
|
* `.copy_remove_param(key)` - *Return a new URL, removing a query parameter. Eg. `url = url.copy_remove_param("max_price")`*.
|
||||||
|
* `.copy_update_params(params)` - *Return a new URL, updating the query parameters. Eg. `url = url.copy_update_params({"color_scheme": "dark"})`*.
|
||||||
|
* `.join(url)` - *Return a new URL, given this URL as the base and another URL as the target. Eg. `url = url.join("../navigation")`*.
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Query Parameters
|
||||||
|
|
||||||
|
The `QueryParams` class provides an immutable multi-dict for accessing URL query parameters.
|
||||||
|
|
||||||
|
They can be instantiated from a dictionary.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> params = httpx.QueryParams({"color": "black", "size": "medium"})
|
||||||
|
>>> params
|
||||||
|
<QueryParams 'color=black&size=medium'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> params = ahttpx.QueryParams({"color": "black", "size": "medium"})
|
||||||
|
>>> params
|
||||||
|
<QueryParams 'color=black&size=medium'>
|
||||||
|
```
|
||||||
|
|
||||||
|
Multiple values for a single key are valid.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> params = httpx.QueryParams({"filter": ["60GHz", "75GHz", "100GHz"]})
|
||||||
|
>>> params
|
||||||
|
<QueryParams 'filter=60GHz&filter=75GHz&filter=100GHz'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> params = ahttpx.QueryParams({"filter": ["60GHz", "75GHz", "100GHz"]})
|
||||||
|
>>> params
|
||||||
|
<QueryParams 'filter=60GHz&filter=75GHz&filter=100GHz'>
|
||||||
|
```
|
||||||
|
|
||||||
|
They can also be instantiated directly from a query string.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> params = httpx.QueryParams("color=black&size=medium")
|
||||||
|
>>> params
|
||||||
|
<QueryParams 'color=black&size=medium'>
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> params = ahttpx.QueryParams("color=black&size=medium")
|
||||||
|
>>> params
|
||||||
|
<QueryParams 'color=black&size=medium'>
|
||||||
|
```
|
||||||
|
|
||||||
|
Keys and values are always represented as strings.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> params = httpx.QueryParams("sort_by=published&author=natalie")
|
||||||
|
>>> params["sort_by"]
|
||||||
|
'published'
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> params = ahttpx.QueryParams("sort_by=published&author=natalie")
|
||||||
|
>>> params["sort_by"]
|
||||||
|
'published'
|
||||||
|
```
|
||||||
|
|
||||||
|
When coercing query parameters to strings you'll see the same escaping behavior as HTML form submissions. The result will always be a printable ASCII string.
|
||||||
|
|
||||||
|
<div class="tabs"><a onclick="httpx()" class="httpx">httpx</a> <a onclick="ahttpx()" class="ahttpx hidden">ahttpx</a></div>
|
||||||
|
|
||||||
|
```{ .python .httpx }
|
||||||
|
>>> params = httpx.QueryParams({"email": "user@example.com", "search": "How HTTP works!"})
|
||||||
|
>>> str(params)
|
||||||
|
'email=user%40example.com&search=How+HTTP+works%21'
|
||||||
|
```
|
||||||
|
|
||||||
|
```{ .python .ahttpx .hidden }
|
||||||
|
>>> params = ahttpx.QueryParams({"email": "user@example.com", "search": "How HTTP works!"})
|
||||||
|
>>> str(params)
|
||||||
|
'email=user%40example.com&search=How+HTTP+works%21'
|
||||||
|
```
|
||||||
|
|
||||||
|
### Accessing query parameters
|
||||||
|
|
||||||
|
Query parameters are accessed using a standard dictionary style interface...
|
||||||
|
|
||||||
|
* `.get(key, default=None)` - *Return the value for a given key, or a default value. If multiple values for the key are present, only the first will be returned.*
|
||||||
|
* `.keys()` - *Return the unique keys of the query parameters. Each key will be a `str` instance.*
|
||||||
|
* `.values()` - *Return the values of the query parameters. Each value will be a list of one or more `str` instances.*
|
||||||
|
* `.items()` - *Return the key value pairs of the query parameters. Each item will be a two-tuple including a `str` instance as the key, and a list of one or more `str` instances as the value.*
|
||||||
|
|
||||||
|
The following methods are also available for accessing query parameters as a multidict...
|
||||||
|
|
||||||
|
* `.get_all(key)` - *Return all the values for a given key. Returned as a list of zero or more `str` instances.*
|
||||||
|
* `.multi_items()` - *Return the key value pairs of the query parameters. Each item will be a two-tuple `(str, str)`. Repeated keys may occur.*
|
||||||
|
* `.multi_dict()` - *Return the query parameters as a dictionary, with each value being a list of one or more `str` instances.*
|
||||||
|
|
||||||
|
### Modifying query parameters
|
||||||
|
|
||||||
|
The following methods can be used to create modified query parameter instances...
|
||||||
|
|
||||||
|
* `.copy_set(key, value)`
|
||||||
|
* `.copy_append(key, value)`
|
||||||
|
* `.copy_remove(key)`
|
||||||
|
* `.copy_update(params)`

A custom transport that handles sending requests directly to an WSGI app.

The simplest way to use this functionality is to use the `app` argument.
|

|
|
||||||
```
|
|

client = httpx.Client(app=app)
|
|

```
|

|

Alternatively, you can setup the transport instance explicitly.

Arguments:
|

|
|
||||||
* `app` - The WSGI application.
|
|
||||||
* `raise_app_exceptions` - Boolean indicating if exceptions in the application
|
|
||||||
should be raised. Default to `True`. Can be set to `False` for use cases
|
|
||||||
such as testing the content of a client 500 response.
|
|
||||||
* `script_name` - The root path on which the WSGI application should be mounted.
|
