HTTP3

HTTP3 is a next-generation HTTP client for Python 3.

Note: This project should be considered as an "alpha" release. It is substantially API complete, but there are still some areas that need more work.

Let's get started...

>>> import http3
>>> r = http3.get('https://www.example.org/')
>>> r

>>> r.status_code
200
>>> r.protocol
'HTTP/2'
>>> r.headers['content-type']
'text/html; charset=UTF-8'
>>> r.text
'\n\n\n<title>Example Domain</title>...'

Features

HTTP3 builds on the well-established usability of requests, and gives you:

• A requests-compatible API.
• HTTP/2 and HTTP/1.1 support.
• Support for issuing HTTP requests in parallel. (Coming soon)
• Standard synchronous interface, but with async/await support if you need it.
• Ability to make requests directly to WSGI 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 (Digest is still TODO)
• Elegant Key/Value Cookies
• Automatic Decompression
• Automatic Content Decoding
• Unicode Response Bodies
• Multipart File Uploads
• HTTP(S) Proxy Support (TODO)
• Connection Timeouts
• Streaming Downloads
• .netrc Support (TODO)
• Chunked Requests

Installation

Install with pip:

$ pip install http3

HTTP3 requires Python 3.6+

Documentation

Project documentation is available at www.encode.io/http3/.

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

For more advanced topics, see the Advanced Usage section, or the specific topics on making Parallel Requests or using the Async Client.

The Developer Interface provides a comprehensive API reference.

Dependencies

The HTTP3 project relies on these excellent libraries:

• h2 - HTTP/2 support.
• h11 - HTTP/1.1 support.
• certifi - SSL certificates.
• chardet - Fallback auto-detection for response encoding.
• 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.
