HTTPX - A next-generation HTTP client for Python.

HTTPX is a fully featured HTTP client library for Python 3. It includes an integrated command line client, has support for both HTTP/1.1 and HTTP/2, and provides both sync and async APIs.

Install HTTPX using pip:

$ pip install httpx

Now, 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 command-line client.

$ pip install 'httpx[cli]'  # The command line client is an optional dependency.

Which now allows us to use HTTPX directly from the command-line...

Sending a request...

Features

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

A broadly requests-compatible API.
An integrated command-line client.
HTTP/1.1 and HTTP/2 support.
Standard synchronous interface, but with async support if you need it.
Ability to make requests directly to WSGI applications or ASGI applications.
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
Elegant Key/Value Cookies
Automatic Decompression
Automatic Content Decoding
Unicode Response Bodies
Multipart File Uploads
HTTP(S) Proxy Support
Connection Timeouts
Streaming Downloads
.netrc Support
Chunked Requests

Installation

Install with pip:

$ pip install httpx

Or, to include the optional HTTP/2 support, use:

$ pip install httpx[http2]

HTTPX requires Python 3.8+.

Documentation

Project documentation is available at https://www.python-httpx.org/.

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:

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.

HTTPX is BSD licensed code.
Designed & crafted with care.
