在Symfony2应用程序中包含Node.JS+Socket.IO

对于那些可能对答案感兴趣的人:

$ su -

安装Node.JS

$ cd /usr/ports/www/node

$ make install clean

安装NPM

$ cd /usr/ports/www/npm

$make安装干净

安装Socket.IO

$ cd /path/to/your/project/js/public/files

$ npm install socket.io

开发代码

应用程序.js

var http = require('http');
var fs = require('fs');

var server = http.createServer(function(req, res) {
    fs.readFile('./index.html', 'utf-8', function(error, content) {
        res.writeHead(200, {"Content-Type": "text/html"});
        res.end(content);
    });
});

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

io.sockets.on('connection', function (socket) {
    socket.on('newOrder', function () {
        socket.broadcast.emit('message', 'Nouvelle commande');
    });
});

server.listen(4321);

前端

<script src="{{ asset('http://localhost:4321/socket.io/socket.io.js') }}"></script>

<script>
    jQuery(function($) {
        var socket = io.connect('http://localhost:4321');

        $('form').on('submit', function() {
            socket.emit('newOrder', '1');
        });

    });
</script>

后端

<script>
    jQuery(function($) {    
        var socket = io.connect('http://localhost:4321');

        socket.on('message', function(message) {
            alert(message);
        });
    });

</script>

启动服务器

$ node app.js

这就是全部!
