有谁能给我讲讲提交表单的过程？

[lwy7758]

我用winform提交webform的表单. 不知道具体过程是什么样的?

就拿登陆csdn那个表单来说吧...

还有COOKIE该怎样构造?

[hainang1234]

通常是post方法，头和体。
找个抓包工具抓个包，看看传过去的是什么，你也传相应的东西就行了。

[cvman]

你看看CSDN小助手中login类。

[sx_lxh]

你注意login类中，postdata函数中，要post的那个字符串，就是表单中form和/form之间的输入数据的键和值。
至于CSDN小助手里 login类的那句:
请求.CookieContainer.Add(New Cookie("ASP.NET_SessionId", _APSNET_SessionValue, "/", U.Host))应该是保证产生验证码的session和登陆session应为同一session.

[cvman]

你拿什么抓的包？

[lwy7758]

那Session是什么时候产生的？

httpwebRequest.creat(URL)的时候吗？

[lwy7758]

是啊...我也知道啊.....

但就是不知道具体传什么东西?


POST /login.asp HTTP/1.1

上面是我抓的一个包.
我具体该传些什么东西?

[lwy7758]

还有..

主要是POST Cookie时..是不是要根据抓包的内容来?

CSDN小助手里 login类的那句:
请求.CookieContainer.Add(New Cookie("ASP.NET_SessionId", _APSNET_SessionValue, "/", U.Host))

我一直没看明白.

[lwy7758]

这个是csdn小助手登陆csdn过程的一部分：
'#########################################################################'
Private _APSNET_SessionValue As String
Dim 请求 As HttpWebRequest
请求.CookieContainer = New CookieContainer
Dim U As New Uri(StrUrl)
请求.CookieContainer.Add(New Cookie("ASP.NET_SessionId", _APSNET_SessionValue, "/", U.Host))
'#######################################################################'

为什么会这么写？
这是我抓的登陆CSDN的包：

那如果换成是这个包 我应该怎么写CookieContainer?
