如何链接脚本并在生产服务器上连接socket.io？

我是新的所有相关的JavaScript programmimg，我有一个应用程序使用nodejs和socket.io本地（Mac）上完美的工作。 然而，我不知道如何链接的socket.io脚本，并不知道如何从应用程序连接到socket.io一次在我运行的服务器（Hostgator专用运行CentOS），我也使用claudflare。

我已经尝试了几种组合：

的index.php

<script src="/socket.io/socket.io.js"></script> //or also <script src="socket.io/socket.io.js"></script> //console output is: Loading failed for the <script> with source “https://www.example.com/socket.io/socket.io.js”. <script src="my_ip_number/socket.io/socket.io.js"></script> //console output is: Loading failed for the <script> with source “https://www.example.com/my_ip_number/socket.io/socket.io.js”. <script src="my_ip_number:8080/socket.io/socket.io.js"></script> //console output is: Loading failed for the <script> with source “https://www.example.com/my_ip_number:8080/socket.io/socket.io.js”. //the most odd one <script src="https://my_ip_number/socket.io/socket.io.js"></script> //console output is: Loading failed for the <script> with source “https://0.0.0/my_ip_number/socket.io/socket.io.js”. 

app.js（客户端）

 var socket = io.connect('my_ip_number:8080', { query: 'userid='+userOnline}); 

EDITED

如果我链接到CDN，我可以使脚本链接工作：

 <script src="https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.4/socket.io.js"></script> 

这也对应于服务器版本。 在这种情况下，我会在控制台上得到以下错误：

 client connect_error: Error: xhr poll error Stack trace: r.prototype.onError@https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.4/socket.io.js:2:7328 o.prototype.doPoll/<@https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.4/socket.io.js:2:1979 r.prototype.emit@https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.4/socket.io.js:1:12370 i.prototype.onError@https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.4/socket.io.js:2:3683 i.prototype.create/n.onreadystatechange/<@https://cdnjs.cloudflare.com/ajax/libs/socket.io/2.0.4/socket.io.js:2:3309 

server.js

 var express = require('express'); var path = require('path'); var bodyParser = require('body-parser'); var app = express(); var http = require('http').Server(app); app.set('views', path.join(__dirname, 'views')); app.set('view engine', 'html'); app.use(bodyParser.json()); app.use(bodyParser.urlencoded({ extended: false })); app.use(express.static(path.join(__dirname, 'public'))); app.get('/', function(req, res){ res.sendFile(__dirname + '/index.html'); }); app.use(function(req, res, next) { var err = new Error('Not Found'); err.status = 404; next(err); }); app.use(function(err, req, res, next) { res.locals.message = err.message; res.locals.error = req.app.get('env') === 'development' ? err : {}; res.status(err.status || 500); res.render('error'); }); module.exports = app; http.listen(8080, function(){ console.log('listening'); }); var io = require('socket.io').listen(http);
