【问题描述】:
我试图在 c# 中创建一个 HTTPS 代理服务器。 有人在这里发布了一个解决方案:
string host = "encrypted.google.com";
string proxy = "127.0.0.1";//host;
int proxyPort = 8888;//443;
byte[] buffer = new byte[2048];
int bytes;
// Connect socket
TcpClient client = new TcpClient(proxy, proxyPort);
NetworkStream stream = client.GetStream();
// Establish Tcp tunnel
byte[] tunnelRequest = Encoding.UTF8.GetBytes(String.Format("CONNECT {0}:443 HTTP/1.1\r\nHost: {0}\r\n\r\n", host));
stream.Write(tunnelRequest , 0, tunnelRequest.Length);
stream.Flush();
// Read response to CONNECT request
// There should be loop that reads multiple packets
bytes = stream.Read(buffer, 0, buffer.Length);
Console.Write(Encoding.UTF8.GetString(buffer, 0, bytes));
// Wrap in SSL stream
SslStream sslStream = new SslStream(stream);
sslStream.AuthenticateAsClient(host);
// Send request
byte[] request = Encoding.UTF8.GetBytes(String.Format("GET https://{0}/ HTTP/1.1\r\nHost: {0}\r\n\r\n", host));
sslStream.Write(request, 0, request.Length);
sslStream.Flush();
// Read response
do
{
bytes = sslStream.Read(buffer, 0, buffer.Length);
Console.Write(Encoding.UTF8.GetString(buffer, 0, bytes));
} while (bytes != 0);
client.Close();
Console.ReadKey();
但是,这不是服务器的代码。它打印响应(作为纯文本),但客户端套接字(浏览器)没有得到响应。
感谢您的帮助, 谢谢。
