Fixie works with any http client library, including urllib2 from the standard library and third-party packages including the popular requests package.

Using requests

To route a specific request through Fixie using requests:

import os, requests
proxyDict = {
              "http"  : os.environ.get('FIXIE_URL', ''),
              "https" : os.environ.get('FIXIE_URL', '')
            }
r = requests.get('http://www.example.com', proxies=proxyDict)

If you intend to route all outbound traffic through Fixie, a simpler option is to set the http_proxy and https_proxy environment variables. Both urllib2 and requests honor the http_proxy and https_proxy environment variables, so you can route all outbound requests through Fixie using these environment variables:

import os, requests
os.environ['http_proxy'] = os.environ.get('FIXIE_URL', '')
os.environ['https_proxy'] = os.environ.get('FIXIE_URL', '')
requests.get("http://www.example.com")

Using urllib2

Using urllib2 to send a specific request through Fixie:

import os, urllib2
proxy  = urllib2.ProxyHandler({'http': os.environ.get('FIXIE_URL', '')})
auth   = urllib2.HTTPBasicAuthHandler()
opener = urllib2.build_opener(proxy, auth, urllib2.HTTPHandler)
response = opener.open('http://www.example.com')
html = response.read()

The urllib2 API is significantly more verbose than that of the requests package. The requests package is a better choice for most applications.
