Question

我是所有相关JavaScript programmimg的新手，我有一个使用nodejs和socket.io的应用程序完美地在本地（Mac）上工作。但是我无法弄清楚如何链接socket.io脚本并且不确定如何在运行的服务器（Hostgator专用运行的CentOS）中从应用程序连接到socket.io，我也在使用claudflare。

我尝试了几种组合：

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，我可以使脚本链接正常工作：

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

这也与服务器版本相对应。在这种情况下，我将在控制台上收到以下错误：

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

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);

非常感谢任何帮助！

如何在生产服务器上链接脚本并连接socket.io？
