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
formhashcookietimeformhashloginfieldpasswordquestionidrefererusername
cookietime 浏览器自动给的是 2592000loginfield 默认的usernamepassword 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0referer 这个则是引用地址 http://www.xxx.com/index.phpusername 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45tidurl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tidreferer这个是引用地址，用网站的首页即可
