WinJS应用程序无法连接Node.js socket.io服务器

Question

I'm build an WP app using HTML5/js/CSS, and today i got a problem. I create a NodeJs server using socket.io fot chat. My server code:

var express = require('express')
  , routes = require('./routes')
  , http = require('http');
var app = express();
var mongodb = require('mongodb');
var url = 'mongodb://localhost:27017/chat';
var MongoClient = mongodb.MongoClient;
  app.configure(function(){
  app.set('port', process.env.PORT || 3456);
  app.set('views', __dirname + '/views');
  app.set('view engine', 'jade');
  app.use(express.bodyParser());
  app.use(express.methodOverride());
  app.use(app.router);
  app.use(express.static(__dirname + '/public'));
});

app.configure('development', function(){
  app.use(express.errorHandler());
});

app.get('/', routes.index);

var server = http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'));
});
var io = require('socket.io').listen(server)
  , guestNumber = 1
  , nickNames = {}
  , numuser = 0;
io.set('log level', 1);

io.on('connection', function (socket) {
...
});

In my app, i use: var socket = io.connect('myipserver:3456/');

IT NOT CONNECT to my server, but when i use browser to connect my ip server, it normal, and in my app, it got error: XMLHttpRequest: Network Error 0x2efd, Could not complete the operation due to error 00002efd .

In package.appxmanifest, i checked Internet ( Client & Server ) Capabilities.

So, do i miss something in my app ? Plz help.

After some Googling I saw this question that has the same error code as your app. Seems to me that this error code says that the app does not see the server. So I don't think it's a socket-related error.

Try making a simple AJAX request to your server (with jQuery: $.get(myipserver:3456/some-static-file) ). If it works, then it's something with the socket communications, otherwise the app does not see the server at all. Good point to start from, I guess.
