Socket.io 'on' jest zwrócenie niezdefiniowane

Question

Ok, więc staram się nauczyć socket.io i otrzymuję ten błąd:

io.socket.on('connection', function (socket) TypeError: Cannot call method 'on' of undefined

herezje mój kod:

var express = require('express') 
    , app = express.createServer() 
    , routes = require('./routes') 
    , user = require('./routes/user') 
    , path = require('path') 
    , io = require('socket.io').listen(app); 


// all environments 
app.set('views', __dirname + '/views'); 
app.set('view engine', 'jade'); 
app.use(express.favicon()); 
app.use(express.logger('dev')); 
app.use(express.bodyParser()); 
app.use(express.methodOverride()); 
app.use(app.router); 
app.use(express.static(path.join(__dirname, 'public'))); 

app.listen(3000); 

app.get('/', routes.index); 
app.get('/users', user.list); 

io.socket.on('connection', function (socket) { 
    socket.emit('news', { hello: 'world' }); 
    socket.on('my other event', function (data) { 
     console.log(data); 
    }); 
}); 

wiem to będzie raczej oczywiste.

Answer 1

Powinny być io.sockets.on ("gniazd" zamiast "gniazda"):

io.sockets.on('connection', function (socket) { 
    socket.emit('news', { hello: 'world' }); 
    socket.on('my other event', function (data) { 
     console.log(data); 
    }); 
});

Myślę, że ten kod nie działa. Oto coś, co zrobiłem, aby poradzić sobie z socket.io i serwerem http.

var app = require('http'), 
    io = require('socket.io'); 

var handler = function(req, res) { /* your handler function*/ }; 
var server = app.createServer(handler).listen(8000); 
var ios = io.listen(server); 

ios.sockets.on('connection', function(socket){ 
    socket.emit('message', {'message': 'hello world'}); 
});
