C# TcpClient与带有CCProxy的WebClient

我有以下代码：

        using (TcpClient tc = new TcpClient())
        {
            button1.Enabled = false;
            //string Data = System.Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes("user:123"));
            //tc.Connect("bot.whatismyipaddress.com", 80);
            //tc.Connect("xxx.xx.xxx.xxx", 3128); external proxy works
            try
            {
                //tc.Connect("192.168.1.2", 808); internal proxy doesn't work
                using (NetworkStream ns = tc.GetStream())
                {
                    using (StreamWriter sw = new StreamWriter(ns))
                    {
                        using (StreamReader sr = new StreamReader(ns))
                        {
                            sw.Write(@"GET / HTTP/1.1

");
                            sw.Flush();
                            string Res = sr.ReadToEnd();
                            richTextBox1.Text = Res;
                        }
                    }
                }
            }
            catch (Exception ex)
            {
                richTextBox1.Text = ex.Message;
            }
            button1.Enabled = true;
        }
    }

这对任何外部代理URL都很好，但我想尝试身份验证部分，所以我使用了CCProxy，然后我意识到代码不能与本地CCProxy一起工作（尽管WebClient工作得很好），TcpClient respond是完全空的

我不知道它是如何在外部工作的，而不是在内部工作的！ [编辑] 除了ccproxy之外，还有其他方法测试身份验证吗？

好的，这是答案

byte[] buffer = new byte[2048];
        int bytes;
        using (TcpClient tc = new TcpClient("192.168.1.2", 808))
        {                
            button1.Enabled = false;                
            NetworkStream stream = tc.GetStream();

            // Establish Tcp tunnel
            byte[] tunnelRequest = Encoding.UTF8.GetBytes(String.Format("CONNECT {0}:80  HTTP/1.1\r\nHost: {0}\r\n\r\n", "bot.whatismyipaddress.com"));
            stream.Write(tunnelRequest, 0, tunnelRequest.Length);
            stream.Flush();

            // Read response to CONNECT request
            bytes = stream.Read(buffer, 0, buffer.Length);
            richTextBox1.Text  = Encoding.UTF8.GetString(buffer, 0, bytes);
            // Establish Get
            tunnelRequest = Encoding.UTF8.GetBytes(String.Format(@"GET / HTTP/1.1
Host: bot.whatismyipaddress.com
Connection: close
Cache-Control: max-age=0

"));
            stream.Write(tunnelRequest, 0, tunnelRequest.Length);
            stream.Flush();
            bytes = stream.Read(buffer, 0, buffer.Length);
            richTextBox1.Text += Encoding.UTF8.GetString(buffer, 0, bytes);
            button1.Enabled = true;

我必须先“连接”代理才能通过它打开连接，然后像往常一样发送“GET”。 以及实现用户和pass（基本授权）

我已经编辑了你的标题。请看，“，其中的共识是“不，他们不应该”。CCProxy究竟是什么样的代理？HTTP代理？为了支持HTTP代理，您需要创建特殊的HTTP请求并将它们发送到代理，而您的代码并没有这样做。WebClient等可以自动处理这些问题。为什么不直接使用它们？@Matti Virkkunen:我已经知道如何使用WebClient，但我想学习如何处理TcpClient，是的，它是HTTP代理，监听端口808。但它确实与外部代理配合得很好！！给我另一种测试身份验证的方法。。代理代码可以很好地与外部代理配合使用。

string Data = System.Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes("user:123"));
byte[] tunnelRequest = Encoding.UTF8.GetBytes(String.Format("CONNECT {0}:80  HTTP/1.1\r\nHost: {0}\r\nProxy-Authorization: Basic {1}\r\n\r\n", "bot.whatismyipaddress.com", Data));
