idhttp组件post网页问题

Question

最近为了学习，做一个小小BBS灌水回贴器，登录没问题，可就是对get来的贴无法回复，post后返回来的结果是：抱歉，您的请求来路不正确或表单验证串不符，无法提交
网站是PHP Discuz! X2
代码如下：
 IdHttp1.AllowCookies:=True;
    IdHttp1.HandleRedirects:=True;
    IdHTTP1.HTTPOptions:=IdHTTP1.HTTPOptions+[hoKeepOrigProtocol];
    //IdHttp1.Request.Accept := 'image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, application/x-shockwave-flash, application/msword, application/vnd.ms-excel, application/vnd.ms-powerpoint, application/xaml+xml, application/x-ms-xbap, application/x-ms-application, application/vnd.ms-xpsdocument, */*';
    IdHttp1.Request.AcceptLanguage := 'zh-cn';
    IdHttp1.Request.AcceptEncoding := 'gzip,deflate';
    IdHttp1.Request.ContentLength := 98;
    IdHttp1.Request.ContentType:='application/x-www-form-urlencoded' ;
    IdHttp1.Request.Connection := 'Keep-Alive';
    IdHttp1.Request.CacheControl := 'no-cache';
    IdHttp1.Request.UserAgent := 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET4.0C; .NET4.0E; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET CLR 2.0.50727)';
    IdHttp1.Host := 'bbs.hfdiaoyu.com';    IdHttp1.Request.CustomHeaders.Text:='Cookie:'+mycookie;            
    IdHttp1.Request.Referer := 'http://XXX/thread-19180-1-1.html';
    IdHTTP1.Request.ContentType := 'application/x-www-form-urlencoded';
    poslist.Add('posttime=');
    poslist.Add('formhash=469b4851');
    poslist.Add('subject=');    poslist.Add('message=' + Edit2.Text);
    restr := IdHttp1.Post('http://XXX/forum.php?mod=post&action=reply&fid=12&tid=19180&extra=page%3D1&replysubmit=yes&infloat=yes&handlekey=fastpost',poslist);

Answer 2

哎 CSDN真的没以前的CSDN了~~~有点失望之

Answer 3

你Post的值是不是正确的？有的网站会检测机器人的

Answer 4

来路不正确的原因就是idhttp的头不被服务器接受，先用webbroswer获得到cookie，然后idhttp构造头
当然，用webbroswer来做要简单一些

Answer 5

用浏览器操作，抓包分析一下referer的变化

Answer 6

一般是cookies问题。
