本代码演示了python的urllib2模块如何使用代理，以及需要登录验证的proxy

# The proxy address and port:proxy_info = { 'host' : 'proxy.myisp.com',               'port' : 3128             }# We create a handler for the proxyproxy_support = urllib2.ProxyHandler({"http" : "http://%(host)s:%(port)d" % proxy_info})# We create an opener which uses this handler:opener = urllib2.build_opener(proxy_support)# Then we install this opener as the default opener for urllib2:urllib2.install_opener(opener)# Now we can send our HTTP request:htmlpage = urllib2.urlopen("http://sebsauvage.net/").read(200000)#如果代理需要验证proxy_info = { 'host' : 'proxy.myisp.com',               'port' : 3128,               'user' : 'John Doe',               'pass' : 'mysecret007'             }proxy_support = urllib2.ProxyHandler({"http" : "http://%(user)s:%(pass)s@%(host)s:%(port)d" % proxy_info})opener = urllib2.build_opener(proxy_support)urllib2.install_opener(opener)htmlpage = urllib2.urlopen("http://sebsauvage.net/").read(200000)
