urllib3 is a powerful, user-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:
Client-side TLS/SSL verification.
File uploads with multipart encoding.
Helpers for retrying requests and dealing with HTTP redirects.
Support for gzip, deflate, and brotli 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'
