下面简单说下过程：
首先是得到了login的post地址：http://www.xxx.com/logging.php?action=login&loginsubmit=yes
几个关键的parameter是



cookietime 浏览器自动给的是 2592000

loginfield 默认的username

password 密码

questionid 这个貌似是登录时的回答问题，这个论坛没有强制回答所以用默认的0

referer 这个则是引用地址 http://www.xxx.com/index.php
username 用户名

formhash 最后这个貌似这个是随机的，不固定，可也是个关键参数，所以就直接用正则查找之

args = {
'loginurl': 'http://www.xxx.com/logging.php?action=login',
'loginsubmiturl': 'http://www.xxx.com/logging.php?action=login&loginsubmit=yes',
'fidurl': 'http://www.xxx.com/forum-%s-1.html',
'tidurl': 'http://www.xxx.com/thread-%s-1-1.html',
'replysubmiturl': 'http://www.xxx.com/post.php?action=reply&replysubmit=yes&infloat=yes&handlekey=fastpost&fid=%s&tid=%s',
'referer':'http://www.xxx.com/index.php'
}

loginurl为登录面页，用于获得formhash的值

loginsubmiturl为post登录参数的地址

fidurl这个是版块的ID，url中%s那里即为fid，这样的url http://www.xxx.com/forum-45-1.html，fid即为45
tidurl是帖子的id，查找方法同上

replysubmiturl这个是回复帖子post参数的url，要定位一个帖子前提得知道fid和tid

referer这个是引用地址，用网站的首页即可
