HTTP3

Build Status Coverage Package version

HTTP3 is a next-generation HTTP client for Python.

Note: This project should be considered as an "alpha" release. It is substantially API complete, but there are still some areas that need more work.


Let's get started...

>>> import http3
>>> r = http3.get('https://www.example.org/')
>>> r.status_code
<StatusCode.OK: 200>
>>> r.protocol
'HTTP/2'
>>> r.headers['content-type']
'text/html; charset=UTF-8'
>>> r.text
'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'

Features

HTTP3 builds on the well-established usability of requests, and gives you:

  • A requests-compatible API.
  • HTTP/2 and HTTP/1.1 support.
  • Support for issuing HTTP requests in parallel.
  • Standard synchronous interface, but with async/await support if you need it.
  • Strict timeouts everywhere.
  • Fully type annotated.
  • 100% test coverage.

Plus all the standard features of requests...

  • International Domains and URLs
  • Keep-Alive & Connection Pooling
  • Sessions with Cookie Persistence
  • Browser-style SSL Verification
  • Basic/Digest Authentication Digest is still TODO
  • Elegant Key/Value Cookies
  • Automatic Decompression
  • Automatic Content Decoding
  • Unicode Response Bodies
  • Multipart File Uploads TODO
  • HTTP(S) Proxy Support TODO
  • Connection Timeouts
  • Streaming Downloads
  • .netrc Support TODO
  • Chunked Requests

Documentation

For a run-through of all the basics, head over to the QuickStart.

For more advanced topics, see the Parallel Requests or Async Client documentation.

The Developer Interface provides a comprehensive API reference.

Dependencies

The HTTP3 project relies on these excellent libraries:

  • h2 - HTTP/2 support.
  • h11 - HTTP/1.1 support.
  • certifi - SSL certificates.
  • chardet - Fallback auto-detection for response encoding.
  • idna - Internationalized domain name support.
  • rfc3986 - URL parsing & normalization.
  • brotlipy - Decoding for "brotli" compressed responses. (Optional)

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.
