http proxy

[mykolasglinskis]

trying to connect and work via proxy. my code looks like this ` private void Connect(string address, int port, bool useProxy) { if (!useProxy) { _tcpClient = new TcpClient(); var ipAddress = IPAddress.Parse(address); _tcpClient.Connect(ipAddress, port); } else { //TODO port is always 80 if we are behind proxy _tcpClient = connectViaHTTPProxy(address, 80); } }

    static TcpClient connectViaHTTPProxy(
        string targetHost,
        int targetPort)
    {

        var telegramurl = "http://" + targetHost + ":" + targetPort;

        var proxyUri = WebRequest.DefaultWebProxy.GetProxy(new Uri(telegramurl));

        WebResponse response = null;
        var retry = 10;
        while(retry >= 0)
        {
            var request = (HttpWebRequest)WebRequest.Create(telegramurl);
            request.KeepAlive = true;
            var webProxy = new WebProxy(proxyUri);
            request.Proxy = webProxy;
            request.Method = "CONNECT";
            request.Timeout = 3000;

            retry--;
            try
            {
                response = request.GetResponse();
                break;
            }
            catch (Exception ex)
            {
                 if (retry >=0 && ex.Message.Equals("The operation has timed out", StringComparison.InvariantCultureIgnoreCase))
                {
                    Console.WriteLine($"10/{retry} Timout happened {ex}");
                }
                else
                {
                    throw new Exception("Something went wrong", ex);
                }
            }
        }

        var responseStream = response.GetResponseStream();
        Debug.Assert(responseStream != null);

        const BindingFlags Flags = BindingFlags.NonPublic | BindingFlags.Instance;

        var rsType = responseStream.GetType();
        var connectionProperty = rsType.GetProperty("Connection", Flags);

        var connection = connectionProperty.GetValue(responseStream, null);
        var connectionType = connection.GetType();
        var networkStreamProperty = connectionType.GetProperty("NetworkStream", Flags);

        var networkStream = networkStreamProperty.GetValue(connection, null);
        var nsType = networkStream.GetType();
        var socketProperty = nsType.GetProperty("Socket", Flags);
        var socket = (Socket)socketProperty.GetValue(networkStream, null);

        return new TcpClient { Client = socket };
    }`

for some reason timeouts are happening while connecting - not always but from time to time.

I think using the StarkSoft is useful. take a look at #824 issue.

I have tried StarkSoft with Socks5ProxyClient but not working so i want to try HttpProxyClient but HttpProxyClient not support http proxy with username and password. Is StarkSoft working with you?

@vuminhit I don't use StarkSoft anymore and this repository. you can use the main API with tdsharp. then you can use the core function addProxy.
