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...

HTTPX builds on the well-established usability of
requests, and gives you:
- A broadly requests-compatible API.
- An integrated command-line client.

- 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
- International Domains and URLs
- Keep-Alive & Connection Pooling
- Sessions with Cookie Persistence
- Browser-style SSL Verification
- Basic/Digest Authentication
- Elegant Key/Value Cookies

The HTTPX project relies on these excellent libraries:
httpcore- The underlying transport implementation for
h11- HTTP/1.1 support.
certifi- SSL certificates.
rfc3986- URL parsing & normalization.
idna- Internationalized domain name support.
sniffio- Async library autodetection.
As well as these optional installs:
h2- HTTP/2 support. (Optional, with
socksio- SOCKS proxy support. (Optional, with
rich- Rich terminal support. (Optional, with
click- Command line client support. (Optional, with
brotlicffi- Decoding for "brotli" compressed responses. (Optional, with
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.
