Cake Websocket Save

CakePHP WebSocket Plugin

by Olivier Louvignes

Description

This repository contains a [CakePHP 2.0]+(https://github.com/cakephp) plugin that provides:

• WebSocket Object (that extends HttpSocket core class) to act as websocket client

• Publishable Behavior that aims to provide easy broadcasting of changes occuring in your models

Installation

1. Clone this plugin to app/Plugin/WebSocket

2. Load the plugin in your app/config/bootstrap.php file :

    define('SERVER_NAME', $_SERVER['SERVER_NAME']);
    CakePlugin::load('WebSocket');
   

3. To configure one of your model to use the Publishable Behavior.

    public $actsAs = array('WebSocket.Publishable' => array('fields' => array('name', 'status_date', 'status_code', 'status_progress')),
   

4. To configure one of your controller to use a socket.

    App::import('Plugin/WebSocket/Lib/Network/Http', 'WebSocket', array('file'=>'WebSocket.php'));
    $websocket = new WebSocket(array('port' => 8080, 'scheme'=>'ws'));
   

5. Setup a Node WebSocket server using Socket.io like:

    var io = require('socket.io').listen(8080);
   
    io.sockets.on('connection', function (socket) {
      socket.emit('news', { hello: 'world' });
      socket.on('my other event', function (data) {
        console.log(data);
      });
    });
   

6. Implement this custom Exception

    // in bootstrap.php
    require(APP . 'Lib' . DS . 'MyExceptions.php');
   
   
    // in /Lib/MyExceptions.php
    class ServiceUnavailableException extends CakeException {
   
        protected $_messageTemplate = 'Test';
    }
   

Interface

Quick example:

$websocket = new WebSocket(array('port' => 8080, 'scheme'=>'ws'));

if($websocket->connect()) {

	$someData = array('notify' => false, 'foo' => $bar);
	$websocket->emit('my other event', $someData);

}
