I want to send push notifications via C# socket server to React Native. On react native side, I use socket.io. React Native connects to the server, but never receives a message back.

React Native code:

socket = io.connect('xx.xx.xx.xx:2201');



    socket.on((messages) => {

      console.log("response" + JSON.stringify(messages));   

});

Server Code:

 public static void StartListening()

    {

        byte bytes = new Byte[1024];  

        IPHostEntry ipHostInfo = Dns.GetHostEntry(Dns.GetHostName());

        IPAddress ipAddress = ipHostInfo.AddressList[0];

        IPEndPoint localEndPoint = new IPEndPoint(ipAddress, 11000);



        /

        Socket listener = new Socket(ipAddress.AddressFamily,SocketType.Stream, ProtocolType.Tcp);

        listener.Bind(localEndPoint);

        listener.Listen(10);

            while (true)

            {

                Socket handler = listener.Accept();

                data = null;

            int bytesRec = handler.Receive(bytes);

            data += Encoding.ASCII.GetString(bytes, 0, bytesRec);

            Console.WriteLine("Receieved message and sent: " + data);

            byte msg1 = Encoding.ASCII.GetBytes("jjjjjj");

            handler.Send(msg1);

                handler.Shutdown(SocketShutdown.Both);

                handler.Close();

            }



        Console.WriteLine("nPress ENTER to continue...");

        Console.Read();



    }

Maybe this is help you.

import SocketIOClient from 'socket.io-client';

this.socket = SocketIOClient('xx.xx.xx.xx:2201', {

        transports: ['websocket']

    });

 this.socket.on('message', (message) => { // you can send 'message' emit from server side and than get the on by using 'message' keyword

     console.log(message)

 });
