Python 自动登录网站（处理Cookie）

look321

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

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）
