诸位， V2EX 自动签到脚本崩了，你们发现了吗？

直接上代码，自用于 python 3.4 环境测试通过

自行修改 u:'username', p:'password' 这两个 username password 字符串为自己的帐号密码

# coding:utf-8

import re
import requests

session = requests.Session()

# 领取 X 铜币
# 每日登录奖励已领取

session.headers = base_headers

resp = session.get('http://v2ex.com/signin')

resp = session.post('http://v2ex.com/signin', {u:'username', p:'password', 'once':once_code, 'next':'/'})
resp = session.get('http://v2ex.com/mission/daily')

if u'每日登录奖励已领取' in resp.text:
    print('Already got it.')
else:
    resp = session.get('http://v2ex.com' + re.search(r'/mission/daily/redeem\?once=\d+', resp.text).group())
    print(resp.ok)
