如何设置代理：

import urllib2
enable_proxy = True
proxy_handler = urllib2.ProxyHandler({"http" : 'http://some-proxy.com:8080'})
null_proxy_handler = urllib2.ProxyHandler({})
if enable_proxy:
    opener = urllib2.build_opener(proxy_handler)
else:
    opener = urllib2.build_opener(null_proxy_handler)
urllib2.install_opener(opener)

 handler = urllib2.HTTPCookieProcessor(cookie)
 opener = urllib2.build_opener(handler)

     print 'Name = ' + item.name
     print 'Value = ' + item.value
