Package version

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 currently 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>...'

Features

HTTPX is a high performance asynchronous HTTP client, that builds on the
well-established usability of requests, and gives you:

Documentation

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

For more advanced topics, see the Advanced Usage section,
the async support section, or the HTTP/2 section.

The Developer Interface provides a comprehensive API reference.

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.
  • 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.

Installation

Install with pip:

HTTPX requires Python 3.6+
