HTTPWebRequest登录。登录后浏览

登录，并作出新的（饼干）会议（systempage.local/login.php中）
如果登录成功定位到页面，并做一些事情（导航到systempage.local/index.php文件）

我正在尝试编写本地网络中某个站点的应用程序。
login.php通过usral重定向到index.php。（在浏览器中）
我有我的webrequest准备登录到它。（它的工作原理，到目前为止）HTTPWebRequest登录。登录后浏览

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Text; 
using System.Windows.Forms; 
using System.Net; 
using System.IO; 

namespace WindowsFormsApplication1 
{ 
public partial class Form1 : Form 
{ 
    public Form1() 
    { 
     InitializeComponent(); 
    } 

    string sThepage; 
    CookieContainer logincookie; 

    private void button1_Click(object sender, EventArgs e) 
    { 
     string strPostData = "user_name=" + txtUser.Text + "&password=" + txtPass.Text + "&language=en&action%3Asubmit=Submit"; 
     CookieContainer tempCookies = new CookieContainer(); 

     ASCIIEncoding encoding = new ASCIIEncoding(); 
     byte[] data = encoding.GetBytes(strPostData); 

     HttpWebRequest postReq = (HttpWebRequest)WebRequest.Create("system.local/Login.php"); 
     postReq.Method = "POST"; 
     postReq.KeepAlive = true; 
     postReq.AllowAutoRedirect = false; 
     postReq.Accept = "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; 

     postReq.ContentType = "application/x-www-form-urlencoded"; 
     postReq.Referer = "system.local/interface/Login.php"; 
     postReq.UserAgent = "User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:14.0) Gecko/20100101 Firefox/14.0.1"; 
     postReq.ContentLength = data.Length; 

     Stream postreqStream = postReq.GetRequestStream(); 
     postreqStream.Write(data, 0, data.Length); 
     postreqStream.Close(); 

     HttpWebResponse postResponse; 
     postResponse = (HttpWebResponse)postReq.GetResponse(); 
     tempCookies.Add(postResponse.Cookies); 
     logincookie = tempCookies; 

     StreamReader postRegReader = new StreamReader(postResponse.GetResponseStream()); 
     sThepage = postRegReader.ReadToEnd(); 

     // Blanksite if login success. 
     if (!sThepage.Contains("!doctype")) 
     { 
      MessageBox.Show("you logged in"); 
      Navigate(); //Navigate to the index.php 
     } 
     else 
     { 
      MessageBox.Show("Client was unable to connect!");  

     } 

     richTextBox1.Text = sThepage; 
    } 
} 
}

现在我需要一种方法来导航到indexpage（以及futher一些其他网页）

private void Navigate() 
{ 
    // What to do here? 
    // and how to keep my cookie(sesion) for the next page? 
}

你所想必须做的是在登录请求完成之后，将发送给变量/文件的cookie记录下来，并将这些cookie再次发送回每个后续请求。您可以从标题对象中获取Cookie。

可变 'WebHeaderCollection myHeader;' ... '//第一请求（登录） myHeader = postResponse.Headers; ...' 我应该在哪里添加标题？（newReg.cookiecontainer或header？） 'HttpWebRequest newReq =（HttpWebRequest）WebRequest.Create（“system.local/interface/index.php”）; newReq.Headers = myHeader;' ....对不起，格式化不起作用，希望你能理解它。：/ – MrMAG 2012-08-01 10:13:20

主要问题是我应该在哪里添加标头/ cookie？ 'newReg。??? = myHeader;'...希望现在更容易理解:) – MrMAG 2012-08-01 10:23:20
