登录到vBulletin [英] Logging in to vBulletin

问题描述

我正在尝试用Python编写一个程序，该程序登录到vBulletin论坛.

I am trying to do a program in Python which logs in to a vBulletin forum.

我只需要访问一个页面，但是要查看该页面，我必须先登录.

I need to access only one page, but in order to view that page I must be logged in.

这是我的代码:

#-*- 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/usercp.php?variable')
    print response.read()


variables()

问题是它无法登录，我也找不到原因.

The problem is that it doesn't log me in and I can't find the reason why.

推荐答案

1)，您需要将vb_login_name和vb_login_password发送到login.php?do = login

1) you need to send vb_login_name and vb_login_password to login.php?do=login

2)您还需要将以下值发送到login.php?do = login(查看html代码)

2) you need to send below values to login.php?do=login too (view html code)

<input type="hidden" name="s" value="215c619cb0227a30bab788ca0adb1c42" />
<input type="hidden" name="securitytoken" value="guest" />
<input type="hidden" name="do" value="login" />
<input type="hidden" name="vb_login_md5password" />

下面的一行表示您在将这些值发送到login.php之前，应该对md5哈希vb_login_password，vb_login_md5password，vb_login_md5password_utf.

below line means you shoud md5hash the vb_login_password, vb_login_md5password, vb_login_md5password_utf before you send these values to login.php

<form action="login.php?do=login" method="post" onsubmit="md5hash(vb_login_password, vb_login_md5password, vb_login_md5password_utf, 0)">
