Routing with restify and socket.io in node

I have a node app which routes the request based on the url using restfy.

Now in want to bring socket into picture. But app doesnot redirect to the function when when socket.io is used. I am using FlexSocket.IO library in flex.

Here's my code snippet.

// In app.js 
var restify = require('restify')
, http = require('http')
,socket = require('./routes/socket');

var app = restify.createServer();

app.get('/', socket.handle);
app.post('/', socket.handle);

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

app.listen(8080, function() {
  console.log('%s listening at %s', app.name, app.url);
});
io.configure(function() {
  io.set('transports', ['websocket','flashsocket']);
  io.set('flash policy port', 843);
});
exports.io = io;

//In socket.js
exports.handle = function (req, res, next) {
console.log('In Handle'); //doesn't print this
io.sockets.on('connection', function(client){
console.log('Connection establiished');
});

In Flex

private var socket:FlashSocket;
socket = new FlashSocket("localhost:8080");
socket.addEventListener(FlashSocketEvent.CONNECT, onConnect); 
socket.addEventListener(FlashSocketEvent.MESSAGE, onMessage);

protected function onConnect(event:FlashSocketEvent):void 
{
  Alert.show('connect'); //This alert is shown.
}

Is there anything wrong with the code? Why is the socket.handle function not called in node?

Answer 

In app.js, try

var io = require('socket.io').listen(app.server); //app.server instead of just app

注：可能按照官网上的代码 会导致restify运行出错，按照该修改socket.io监听server才可以
