urlopen with proxy support

post.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import urllib
import urllib2

data = urllib2.urlencode({'foo': 'bar'})

r = urllib2.Request('https://www.google.com',        # url
                    data,                            # post data
                    {'Accept': 'application/json'})  # header

res = urllib2.urlopen(r) # performing request

print res.read() # retrieve response

proxy.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import urllib2

proxy_support = urllib2.ProxyHandler({"http": "http://192.168.2.20:8123",
    "https": "http://192.168.2.20:8123"})
opener = urllib2.build_opener(proxy_support)

urllib2.install_opener(opener)

# f = urllib2.urlopen("http://www.google.com")
f = urllib2.urlopen("http://twitter.com/")

print f.read()

A simple example, and it perfectly helped me understand how the ProxyHandler is implemented. You rock
