EC2与socket.io

Question

我为我的节点应用程序设置了一个aws微实例.我也用socket.io.我收到以下错误:

GET http://localhost:3000/socket.io/1/?t=1393065240268 net::ERR_CONNECTION_REFUSED

在应该创建套接字连接时在控制台中.除此之外,节点应用程序也可以.我怀疑它GET不应该朝向localhost服务器的地址.

请注意,在它服务的服务器端节点上记录socket.io:

debug - served static content /socket.io.js

这是我服务器安全组的图片:

.

Socket.io设置:

env = process.env.NODE_ENV || 'development',
packageJson = require('../package.json'),
http = require('http'),
express = require('express'),
RedisStore = require('connect-redis')(express),
SessionSockets = require('session.socket.io'),
path = require('path'),
settings = require('./settings'),
expose = require('express-expose')
//Configure server for io and session.socket.io
tmpApp = express(),
tmpServer = http.createServer(tmpApp),
io = require('socket.io').listen(tmpServer),
appCookieParser = express.cookieParser(settings.cookie.secret),
appRedisStore = new RedisStore(),
sessionIO = new SessionSockets(io, appRedisStore, appCookieParser)

global.App = {
    app: tmpApp,
    server: tmpServer,
    port: process.env.PORT || 3000,
    sessionIO: sessionIO,
    io: io,
    start: function() {
        var setUp = this.util('setUp'),
            socketHandler = require('./socketHandler'),
            self = this

            setUp.initialize(function(err, waitingGames) {
                if (err) {
                    console.log('error at initializing the application')
                    process.exit(0)
                }
                if (!self.started) {
                    self.started = true
                    self.server.listen(self.port)

                    socketHandler()

                    console.log("Running App Version " + App.version + " on port " + App.port + " in " + App.env + " mode")
                }
            })

    },
 ...
 }

UPDATE

当我改变我的端口时,80我得到一个不同的错误:

 XMLHttpRequest cannot load http://localhost/socket.io/1/?t=1393067003774. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://ec2-54-214-136-70.us-west-2.compute.amazonaws.com' is therefore not allowed access.

我发现了这个问题.这是在客户端.我正在联系localhost.这是一个愚蠢的错误,但在开发过程中你不会注意这些细节,看起来很自然socket.io应该从你服务内容的地方连接到root.

由于我正在使用EC2,并且在每次重启后我得到了不同的DNS地址,我已经发送到我正在初始化socket.io正确的req.headers.host(使用express-expose)页面.
