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 0.13.*
release, so that you're able to properly review API changes between package updates. A 1.0 release is expected to be issued sometime around mid-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]>Features
HTTPX builds on the well-established usability of requests, and gives you:
- A broadly requests-compatible API.
- Standard synchronous interface, but with async support if you need it.
- HTTP/1.1 and HTTP/2 support.
- Ability to make requests directly to WSGI applications or ASGI applications.
- Strict timeouts everywhere.
- Fully type annotated.
- 99% 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

Dependencies
The HTTPX project relies on these excellent libraries:
httpcore- The underlying transport implementation forhttpx.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.urllib3- Support for thehttpx.URLLib3Transportclass. (Optional)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.
