The next generation HTTP client.
Project description
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 3.7+.
Documentation

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 forhttpx.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, withhttpx[http2])socksio- SOCKS proxy support. (Optional, withhttpx[socks])rich- Rich terminal support. (Optional, withhttpx[cli])click- Command line client support. (Optional, withhttpx[cli])brotliorbrotlicffi- Decoding for "brotli" compressed responses. (Optional, withhttpx[brotli])
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.

Release Information
Changed
- The logging behaviour has been changed to be more in-line with other standard Python logging usages. We no longer have a custom
TRACElog level, and we no longer use theHTTPX_LOG_LEVELenvironment variable to auto-configure logging. We now have a significant amount ofDEBUGlogging available at the network level. Full documentation is available at https://www.python-httpx.org/logging/ (#2547, encode/httpcore#648) - The
Response.iter_lines()method now matches the stdlib behaviour and does not include the newline characters. It also resolves a performance issue. (#2423) - Query parameter encoding switches from using + for spaces and %2F for forward slash, to instead using %20 for spaces and treating forward slash as a safe, unescaped character. This differs from
requests, but is in line with browser behavior in Chrome, Safari, and Firefox. Both options are RFC valid. (#2543) - NetRC authentication is no longer automatically handled, but is instead supported by an explicit
httpx.NetRCAuth()authentication class. See the documentation at https://www.python-httpx.org/advanced/#netrc-support (#2525)
Removed
- The
rfc3986dependancy has been removed. (#2252)
