httpxyz 0.42.0

HTTPXYZ (pronounced "HTTP-ex-why-zee") 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.

About this fork

HTTPXYZ is a fork of HTTPX. HTTPX had no release after November 2024 while bugs affecting real-world usage went unresolved. Our goal is stability: bug fixes only, no breaking API changes.

We mean no harm to the original author or contributors — HTTPX is excellent work. For the full story, see Why we forked HTTPX.

Migrating from HTTPX

For most users, migration is a one-line change:

import httpxyz as httpx

That's it, HTTPXYZ is a drop-in replacement, all APIs, exceptions, and behaviour are identical.

If you want to use HTTPXYZ natively:

import httpxyz
r = httpxyz.get("https://www.example.org/")

Transparent httpx aliasing

Importing httpxyz automatically registers itself as sys.modules["httpx"]. This means that any third-party library which does import httpx internally will receive httpxyz instead, as long as httpxyz was imported first:

import httpxyz          # registers httpxyz as sys.modules["httpx"]
import some_library     # internally does `import httpx` — gets httpxyz

isinstance checks against httpx classes will therefore pass for httpxyz objects, even in code you don't control. See HTTPX Compatibility for full details, including how to set this up correctly when using respx in pytest.

Using HTTPXYZ

Install HTTPXYZ using pip:

$ pip install httpxyz

Now, let's get started:

>>> import httpxyz
>>> r = httpxyz.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 'httpxyz[cli]'  # The command line client is an optional dependency.

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

Sending a request...

Features

HTTPXYZ 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 httpxyz

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

$ pip install httpxyz[http2]

HTTPXYZ requires Python 3.9+.

Dependencies

The HTTPXYZ project relies on these excellent libraries:

• httpcore - The underlying transport implementation for httpxyz.
  • 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 httpxyz[http2])
• socksio - SOCKS proxy support. (Optional, with httpxyz[socks])
• rich - Rich terminal support. (Optional, with httpxyz[cli])
• click - Command line client support. (Optional, with httpxyz[cli])
• brotli or brotlicffi - Decoding for "brotli" compressed responses. (Optional, with httpxyz[brotli])
• zstandard - Decoding for "zstd" compressed responses. (Optional, with httpxyz[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.

Release Information

Fixed

• More thorough registering as httpx for better compatibility for third-party packages that import httpx directly. Thanks to @rgant for the report and fix! (Resolves #53, #54)

Changed

• Bumped the minimum httpcorexyz version to pull in the symmetric submodule-mirror fix on the httpcore side. This is the load-bearing piece for respx interception (since respx patches httpcore.* paths).
