我无法从C＃HTTPWebRequest获取cookie

Question

我有一个要求从登录中获取cookie的要求，因为我会将这个cookie应用于同一页面。这里是我的代码

 string boundary = "41184676334"; 
     string username = "username"; 
     string password = "password"; 


     string login_post_data = 
       "POSTDATA=-----------------------------" + boundary + 
       "\nContent-Disposition: form-data; name=\"login\"" + 
       "\n\n" + username + 
       "\n-----------------------------" + boundary + 
       "\nContent-Disposition: form-data; name=\"key\"" + 
       "\n\n" + password + 
       "\n-----------------------------" + boundary + 
       "\nContent-Disposition: form-data; name=\"clcode\"" + 
       "\n\n" + 
       "\n-----------------------------" + boundary + "--"; 

     var cookies = new CookieContainer(); 

     HttpWebRequest request = (HttpWebRequest)WebRequest.Create("https://site.com/cgi-bin/login.pl?logout"); 
     request.CookieContainer = cookies; 



     request.Method = "POST"; 
     request.ContentType = "multipart/form-data; boundary=---------------------------" + boundary; 

     request.Host = "site.com"; 
     request.UserAgent = "Mozilla/5.0 (Windows NT 5.1; rv:14.0) Gecko/20100101 Firefox/14.0.1"; 
     request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"; 
     request.Referer = "https://site.com/cgi-bin/login.pl?logout"; 
     //request.Headers.Add("POSTDATA", post_data); 

     using (var requestStream = request.GetRequestStream()) 
     { 
      requestStream.Write(StrToByteArray(login_post_data), 0, StrToByteArray(login_post_data).Length); 
     } 



     HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 



     using (Stream stream = response.GetResponseStream()) 
     { 


      StreamReader reader = new StreamReader(stream); 

      string temp = reader.ReadToEnd(); 
      richTextBox1.Text = temp; 
     } 


     foreach (string c in response.Cookies) 
     { 
      listBox1.Items.Add(c); 
     } 

的事情是“https://site.com/cgi-bin/login.pl?logout”是在同一页我登录后，我需要传递Cookie

Answer 1

它看起来像您尝试登录，并在同一时间与您的要求，发送到URL

https://site.com/cgi-bin/login.pl?logout 

取出?logout参数，然后再试一次注销。如果它没有改变任何东西，请更新您的问题。

请进一步解释，你试图达到什么目标，所以我们可以讨论代码是否正确。
