注意http消息的Referer字段，
现在服务器一般会判断这个字段，不符合就不让post。
当然cookie字段是最基本的。
建议用操控IE来post。

谢谢ls，Referer和cookie都好办，这个都实现了，就是发送图片附件不知道怎么搞啊

[cs_iceworld]

怎么没人哦，分不够可以再加呀！

[eduyu]

用HTTP Watch工具dump下IE发送的POST，稍微研究下就明白了。给你几张图。

我就是用httpwatch抓的呀，但是该怎么post图片附件呀？一般的文字信息我会post

[eduyu]

1，找到能接受带图片post的网页
2，对它用IE来post
3，dump下IE的这个post，看看IE是怎么组织，注意我第三张图，是一个GIF文件。
