urllib3 is a powerful, sanity-friendly HTTP client for Python. Much of the Python ecosystem already uses urllib3 and you should too. urllib3 brings many critical features that are missing from the Python standard libraries:

• Thread safety.
• Connection pooling.
• Client-side SSL/TLS verification.
• File uploads with multipart encoding.
• Helpers for retrying requests and dealing with HTTP redirects.
• Support for gzip and deflate encoding.
• Proxy support for HTTP and SOCKS.
• 100% test coverage.

urllib3 is powerful and easy to use:

>>> import urllib3
>>> http = urllib3.PoolManager()
>>> r = http.request('GET', 'http://httpbin.org/robots.txt')
>>> r.status
200
>>> r.data
'User-agent: *\nDisallow: /deny\n'

urllib3 can be installed with pip:

$ pip install urllib3

Alternatively, you can grab the latest source code from GitHub:

$ git clone git://github.com/shazow/urllib3.git
$ python setup.py install

urllib3 has usage and reference documentation at urllib3.readthedocs.io.

urllib3 happily accepts contributions. Please see our contributing documentation for some tips on getting started.
