import cookielib

import urllib



### loginURL和postVales通过填写表单页面源码或Fiddler等抓包软件获得

### loginURL是处理登录请求的页面(不是填写表单的页面),

loginURL = ""

postValues = {}



### 存储cookie

cj = cookielib.CookieJar()

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))

urllib2.install_opener(opener)



### 登录验证

try:

    opener.open(loginURL, urllib.urlencode(postValues))

except:

    print "error: open() error"



# 登录后可访问任意URL

print opener.open("").read()
