Question

我想在我的应用程序中使用Socket.io添加实时通知，但我在将其集成到我的应用程序中时遇到了问题。当我运行应用程序并查看浏览器日志（控制台）时，

我拒绝连接

（GET http://localhost:1500/socket.io/?EIO=3&transport=polling&t=1434954742052-24 净:: ERR_CONNECTION_REFUSED）

我的应用程序位于localhost：130。我已经阅读了CORS并在我的控制器中应用了持久性。

header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, 
       Content - Type, Accept, Access - Control - Request - Method ");
header("Access-Control-Allow-Methods: GET, POST, OPTIONS, PUT, DELETE");
$method = $_SERVER['REQUEST_METHOD'];
if ($method == "OPTIONS") {
    die();
}

parent::__construct();

这是我的server.js

var io = require('socket.io').listen(1500);
io.sockets.on('connection', function (socket) {
// Let everyone know it's working
socket.emit('startup', { message: 'I Am Working!!' });
});

这是我的client.js

$(function() {
    window.MY_Socket = {
        // Instantiate the Socket.IO client and connect to the server
        socket: io.connect('http://localhost:1500'),

        // This just indicates that a Socket.IO connection has begun.
        startupMessage: function(data) {
            console.log(data.message);
        },
    }
});

我仍然收到error:net::ERR_CONNECTION_REFUSED。我一直在寻找工作，但我仍然可以想办法解决这个问题。期待你的帮助

感谢@DamirMiladinov帮助我，下面是代码。

var express = require('express');
var app = express();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.use(express.static(__dirname));

var onlines = 0
var users = []
var chat = ''

io.on('connection', function(socket){  
  console.log('[!] Um jogador conectou-se.');
  onlines += 1
  io.emit('updateonlines', [onlines]);
  socket.emit('recvmessage', [chat]);

  socket.on('disconnect', function(){
    console.log('[!] Um jogador desconectou-se.');
    onlines -= 1
    io.emit('updateonlines', [onlines]);
  });
});
  [...]

带有Socket.io错误的CodeIgniter：net :: ERR_CONNECTION_REFUSED
