HTTPX - A next-generation HTTP client for Python.

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 0.11.* release, so that you're able to properly review API changes between package updates. A 1.0 release is expected to be issued sometime on or before April 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]>

Dependencies

The httpx project relies on these excellent libraries:

  • urllib3 - Sync client support.
  • h11 - HTTP/1.1 support.
  • h2 - HTTP/2 support.
  • certifi - SSL certificates.
  • chardet - Fallback auto-detection for response encoding.
  • hstspreload - determines whether IDNA-encoded host should be only accessed via HTTPS.
  • idna - Internationalized domain name support.
  • rfc3986 - URL parsing & normalization.
  • sniffio - Async library autodetection.
  • 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.
