关于POST的问题:您的请求来路不正确，无法提交。

好好比对下抓包的结果吧，Headers里看看少什么了。

这段是我程序运行时候，Wireshark抓的包POST //post.php?action=reply&fid=19&tid=1222671&extra=page%3D1&replysubmit=yes&infloat=yes&handlekey=fastpost&inajax=1 HTTP/1.1

1.你的Content-Length怎么多那么多？
2.Cookie还少

Content-Length的问题我发现了，是程序发送的字节和我在论坛上发送的字节数目不同的，忘记修改为相同的。
可是cookies就不明白为什么这样了。请指教。

这是全部代码struct WebInfo{

1：设置request一下重定向问题，试一试，那个属性忘了。
2：其实可以通过TcpClient直接写入，你抓取到的http头文件。

因为您没用帐号，我用个测试帐号：tempUser 123456789

NetworkCredential^ myCredentials = gcnew NetworkCredential( "MSO","changeme" );
request->Credentials = myCredentials;
request->PreAuthenticate = true;//必須要1：确定一下有没有账号密码然后做如上设置
2：实在不行就有TcpClient 直接写入http头文件吧

人家只要校验一下url或者cookie中某个编号有没有过期就行了，胡乱给你个“你的来路不正”的假说明，也是可以的。

哪个版块可以回帖？你现在的tempUser好像权限特低？

我自己是用了一个比较高权限的帐号测试的，不会有tempUser的问题。
我私信一个帐号与您好哦。
