用Python连接vBulletin 4.2.2论坛

Question

我阅读此页面并且代码仍无效： Logging in to vBulletin

我的代码：

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

import urllib, urllib2, cookielib, hashlib, time

def variables():
    domain = "www.example.com"
    uname = "UserName"
    passwd = "Password"

    # Create url
    if domain.startswith('http://'):
         url = domain
    else:
        url = 'http://' + domain

    login(url, uname, passwd)


def login(url, uname, passwd):
    loginurl = url + '/login.php?do=login'
    md5 = hashlib.md5(passwd);md5 = md5.hexdigest()
    # Options for request
    opts = {
        'do': 'login',
        'vb_login_md5password': md5,
        'vb_login_md5password_utf': md5,
        's': '',
        'vb_login_username': uname, 
        'security_token': 'guest', 
    }
    data = urllib.urlencode(opts)

    # Request header
    global headers
    headers = {
        'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
        'Accept-Language': 'es-es,es;q=0.8,en-us;q=0.5,en;q=0.3',
        'Accept-Encoding': 'gzip,deflate',
        'Accept-Charset': 'ISO-8859-1,utf-8;q=0.7,*;q=0.7',
        'Connection': 'keep-alive',
        'Referer': loginurl,
        'Content-Type': 'application/x-www-form-urlencoded',
        'Content-Lenght': '205'
    }

    # Cookie Handling
    jar = cookielib.CookieJar()
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(jar))

    # Send Request
    opener.addheader = headers
    opener.open(loginurl, data)

    # Check
    response = opener.open('http://example.com/')
    source_code = response.read()
    if source_code.find(uname) != -1:
        print "Login Succeeded."
    else:
        print "Login Failed."


variables()

字段名称的属性值为None（Empty）：

<input type="hidden" name="s" value="" />

为什么代码不起作用？

感谢。

Answer 1

缺少“vb_login_password”，“vb_login_password_hint”，“cookieuser”和“vb_login_md5password_utf”必须为空。

并确定删除标题。
