+This software has been designed for you, with much joy,

+
+ + + +

 

 

+ +

Requests is an elegant and simple HTTP library for Python, built with ♥.

+ +

 

+ +```pycon +>>> import requests +>>> r = requests.get('https://api.github.com/user', auth=('user', 'pass')) +>>> r.status_code +200 +>>> r.headers['content-type'] +'application/json; charset=utf8' +>>> r.encoding +'utf-8' +>>> r.text +u'{"type":"User"...' +>>> r.json() +{u'disk_usage': 368627, u'private_gists': 484, ...} +``` + + + +--------------------------------------------------------------------- + +

 

+ +Requests allows you to send HTTP/1.1 requests extremely easily. There’s no need to manually add query strings to your URLs, or to form-encode your `PUT` & `POST` data — but nowadays, just use the `json` method! + + +Requests is **the most downloaded Python package today**, pulling in around `14M downloads / week`— according to GitHub, Requests is currently [depended upon](https://github.com/psf/requests/network/dependents?package_id=UGFja2FnZS01NzA4OTExNg%3D%3D) by `367_296` repositories. You may certainly put your trust in this code. + + +

Continuous integration fails + under 100% branch coverage. Also it passes the industry-standard `Autobahn + Testsuite`_. + +4. **Performance**: memory use is configurable. An extension written in C + accelerates expensive operations. It's pre-compiled for Linux, macOS and + Windows and packaged in the wheel format for each system and Python version. + +Documentation is a first class concern in the project.

Pick another library for a callback-based API. +* If you're looking for a mixed HTTP / WebSocket library: ``websockets`` aims + at being an excellent implementation of :rfc:`6455`: The WebSocket Protocol + and :rfc:`7692`: Compression Extensions for WebSocket. Its support for HTTP + is minimal — just enough for a HTTP health check. +* If you want to use Python 2: ``websockets`` builds upon ``asyncio`` which + only works on Python 3. ``websockets`` requires Python ≥ 3.6.1. + +What else? +---------- + +Bug reports, patches and suggestions are welcome! + +To report a security vulnerability, please use the `Tidelift security +contact`_.
