python# -*- coding:utf-8 -*-

import requests
from bs4 import BeautifulSoup as bs

loginurl = 'http://www.zhihu.com/'

s = requests.session()
headers = {
        'Referer':'http://www.zhihu.com/', 
        'User-Agent': 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.99 Safari/537.36'
}

data = {
        '_xsrf': bs(s.get(loginurl, headers = headers).content).find(type='hidden')['value'],
        'email': 'email',
        'password': 'passworld',
        'rememberme': 'y'
}

r = s.post(loginurl, data = data, headers = headers)
print r.text

结果是：
<html><title>403: Forbidden</title><body>403: Forbidden</body></html>

希望得到前辈们的指点，万分感谢！
