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

formhash
cookietime
formhash
loginfield
password
questionid
referer
username

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&amp;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&amp;replysubmit=yes&amp;infloat=yes&amp;handlekey=fastpost&amp;fid=%s&amp;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
