Node.js - 在同一端口上使用Socket.io和Express

Question

我需要重构这个节点应用程序,所以socket.io和express使用相同的端口,我可以部署它.它目前按原样运行,但不会在Heroku上运行,除非所有内容都使用相同的端口.

var http = require('http');
var socket = require('socket.io');
var socketServer = http.createServer(app);
var io = socket.listen(socketServer);

var express = require('express');

var app = express();

var bodyParser = require('body-parser');
var path = require('path');

app.set('view engine', 'jade');

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }));

// parse application/json
app.use(bodyParser.json());

app.use(express.static(path.join(__dirname, 'public')));

var routes = require('./config/routes')(app, io);
var timer = require('./server/timer')(app, io);

var server = app.listen(process.env.PORT || 5000, function () {
    console.log('Server running on *:5000');
});

socketServer.listen(8000);

我也只是学习节点,因此非常感谢任何有关重构的提示.

编辑匹配建议的解决方案:( Express以这种方式工作,但它打破了socket.io)

var express = require('express');
var app = express();
var serv = require('http').createServer(app);
var io = require('socket.io').listen(serv);

var bodyParser = require('body-parser');
var path = require('path');

app.set('view engine', 'jade');

// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }));

// parse application/json
app.use(bodyParser.json());

app.use(express.static(path.join(__dirname, 'public')));

var routes = require('./config/routes')(app, io);
var timer = require('./server/timer')(app, io);

serv.listen(process.env.PORT || 5000, function () {
    console.log('Server running on *:' + (process.env.PORT || '5000'));
});

这是控制台中的新错误:

socket.io-1.3.4.js:2 GET http:// localhost:8000/socket.io /？user = Trey&EIO = 3&transport = polling&t = 1424902016787-2

看起来像websockets失败所以它回落到长轮询,这也失败了...

我认为这应该有效.

var express = require('express')
var app = express()
var server = require('http').createServer(app)
var io = require('socket.io')(server)

server.listen(80);
