如何从Web应用程序连接到原始TCP套接字服务器？

Question

I have a web application hosted on AWS written in Laravel/PHP ; i need to let the web application to talk with a socket server listening on port 9090 in a server placed in the same internal network (not in AWS) of the browsers that use the webapp; the socket server DOES NOT support websocket but only raw sockets; how can the client connect to the socket server? Do i need to write client programs in python/other lang to be installed on client machines or is there a better way?

Answer 1

Yes, you need to write client program/script which would listen to the socket and using the script you can manipulate front-end pages.

I would recommend Javascript code which would listen to your web socket at 9090 and based on the received data, you can make changes on the web page.

Here is the sample code for your reference.

<script src="http://localhost:8080/socket.io/socket.io.js"></script>
<script>
    // Create SocketIO instance, connect

    var socket = new io.Socket();

    socket.connect('http://127.0.0.1:8080'); 

    // Add a connect listener
    socket.on('connect',function() {
      console.log('Client has connected to the server!');
    });
    // Add a connect listener
    socket.on('message',function(data) {
      console.log('Received a message from the server!',data);
      // This `data` can be used to show on the page or anything else.
    });
    // Add a disconnect listener
    socket.on('disconnect',function() {
      console.log('The client has disconnected!');
    });

    // Sends a message to the server via sockets
    function sendMessageToServer(message) {
      socket.send(message);
    };
</script>
