urllib3 — urllib3 1.21.1 documentation

# urllib3

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'

## Installing

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
