求哪位高手指点下Post，十万火急

搞了一个通宵的Post。。用Visual Sniffer抓包硬是抓不到Post数据，不知道怎么回事。
用自己的IP他不给数据，用另一个IP可以抓，但就是抓不到Post。。。
换了几个版本，和几个网站，都一样。。。
有哪位耐心的老大能帮我解决下这个问题，谢谢了。搞了一个晚上，把那个明教教主的视频又看了一通
结果要用百兆网卡才能用那个强大的Sniffer..又搞了几小时。。闷。。

在把问题说下，不是说抓到Post数据开头会显示么，把所有+号看完就没发现它。。
开头全是HTTP。。帮我远程看下也行，应该不会是我网卡或者IP设置的问题吧。。求教了。。

7 个解决方案

#1

不是所有数据都是用POST发送，更多的是用GET发送和接收的

#2

试试HttpAnalyzerStdV4呢？！

#3

恩，但是我是跟着一篇教程来的，人家都抓得到，我奇怪我为什么抓不到。所以就苦恼在这。。我要换个思路考虑下了。。谢谢指点。

#4

抓包我觉得用 FIREFOX的firebug 来的快的多而且每步都看的很清楚包括 ajax

哇。看代码5楼是高手咯。。
我把你的代码复制到VB。。有些地方说变量未定义。。

谢谢了，辛苦了。写了这么长代码。。我留着把我的软件做好再看。。
