Python 自动登录网站（处理Cookie）

Python代码 
- def login():
- cj = cookielib.CookieJar()
- opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
- login_url = r'http://zhixing.bjtu.edu.cn/member.php?mod=logging&action=login&loginsubmit=yes&infloat=yes&lssubmit=yes&inajax=1'
- login_data = urllib.urlencode({'cookietime': '2592000', 'handlekey': 'ls', 'password': 'xxx',
- 'quickforward': 'yes', 'username': 'digiter'})
- opener.open(login_url, login_data)
- return opener
返回以后只需要设置url和data就可以Post了。
注意不要在request里设置header，这是因为cookie也是header，如果设置header会导致没有cookie，也就没有登录
Python代码
- request = urllib2.Request(
- url=r'http://zhixing.bjtu.edu.cn/forum.php?mod=post&action=newthread&fid=601&extra=&topicsubmit=yes',
- data=param
- )
- print opener.open(request).read()
轻松搞定设置Discuz X主题分类的功能（cookie要模拟浏览器，这里是模仿firefox）
