HttpWebRequest登陆开心网
最近学HttpWebRequest和HttpWebResponse的应用，可以模拟登陆一些简单的网站了。不过开心网我看不懂请大家帮我分析一下行么？为什么一开始有两个post，我改用代码怎么模拟？写个思路就可以。
一般性我知道只要post给他我的用户名，密码然后返回一个cookie，然后带着这个cookie get下一个登录后的页面就能拿到数据了。可是开心网怎么弄。我用firefox的firebug看了老半天没看懂。 --------------------编程问答-------------------- 你去下一个开心网的外挂 看看就知道了。比如说停车外挂 --------------------编程问答-------------------- 没有源码的吧，而且开心网一直在更新，有哪个能用的么。。 --------------------编程问答-------------------- mark，明天帮你看。 --------------------编程问答--------------------

你测试成功了吗，成功取得登陆后的html了吗？ --------------------编程问答-------------------- 我好像还是取不到。你这个对吗。。 --------------------编程问答--------------------

--------------------编程问答-------------------- 一开始post 的 http://www.kaixin001.com/interface/statLog2.php 没什么用的吗？
static void Main(string[] args)
{
HttpHelper http = new HttpHelper();
System.Net.CookieContainer cookies = new CookieContainer();
string result = http.GetHtml("https://security.kaixin001.com/login/login_auth.php", cookies, "POST", "rcode=&url=%2Fhome%2F&email=123456@qq.com&qazwsx=password&code=");
result = http.GetHtml("http://login.kaixin001.com/home/", cookies);
Console.WriteLine(result.Substring(0, 500));
}
补充：.NET技术 , C#
