Socket.io Javascript nodejs, TCP socket-CodePudding

I am trying to send a TCP Request to a server via IP:PORT...

This code works for me:

var net = require('net'); var client = new net.Socket();
const port = 1337; const HOST = "192.168.1.101";
function connect() {
  client.connect({ port: PORT, host: HOST });
  client.on('data', (data) => {
    console.log(data);
    client.destroy();
    });
  
    client.on('close', function() {
    console.log('Connection closed');
    });
  }

This code hangs, no response: (also note: I input 'http://' prior to the IP in io.connect for the response to not return the hostname as undefined (see below)):

console.log(socket); //returns=> undefined://192.168.1.101:1337
//uri: 'undefined//192.168.1.101:730',


const io = require('socket.io-client');
const socket = io.connect('192.168.1.101:1337');//=undefined hostname; works, but hangs
//const socket = io.connect('http://192.168.1.101:1337'); //works, but hangs as well...

function connect() {
  console.log('connecting...');
  **socket.on('connect', () => {**
    console.log('Successfully connected!');
      // add handlers for socket events
  }); //I never receive response from socket.on('connect', ()=> {...

Either way I try to send a socket, I don't get a response... it's just hanging, waiting for a response...

ANY HELP WOULD BE GREATLY APPRECIATED!

console.log(socket); //this command returns the following response from command down below:

CodePudding user response：

You forgot to declare the protocol in your URL, try http://192.168.1.101:1337 or ws://192.168.1.101:1337 (If your server does not use SSL)

And be sure the server side also implements socket.io server not just TCP protocol.
