HTTPX

HTTPX - A next-generation HTTP client for Python.

Test Suite Package version

HTTPX is a fully featured HTTP client for Python 3, which provides sync and async APIs, and support for both HTTP/1.1 and HTTP/2.

Note: HTTPX should be considered in beta. We believe we've got the public API to a stable point now, but would strongly recommend pinning your dependencies to the 0.14.* release, so that you're able to properly review API changes between package updates. A 1.0 release is expected to be issued sometime in late 2020.

Let's get started...

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

Or, using the async API...

Use IPython or Python 3.8+ with python -m asyncio to try this code interactively.

>>> import httpx
>>> async with httpx.AsyncClient() as client:
>>>     r = await client.get('https://www.example.org/')
>>> r
<Response [200 OK]>

Features

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

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
  • Elegant Key/Value Cookies
  • Automatic Decompression
  • Automatic Content Decoding
  • Unicode Response Bodies
  • Multipart File Uploads
  • HTTP(S) Proxy Support
  • Connection Timeouts

Dependencies

The HTTPX project relies on these excellent libraries:

  • httpcore - The underlying transport implementation for httpx.
    • h11 - HTTP/1.1 support.
    • h2 - HTTP/2 support. (Optional)
  • certifi - SSL certificates.
  • chardet - Fallback auto-detection for response encoding.
  • rfc3986 - URL parsing & normalization.
    • idna - Internationalized domain name support.
  • sniffio - Async library autodetection.
  • urllib3 - Support for the httpx.URLLib3Transport class. (Optional)
  • 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.
