I want to use websocket for a voting application. There is two parts: one is a chat channel and an other one is a command channel where information about the question, the available answers, the countdown etc will travel.
On the client side, I use Autobahn|JS as library. I can subscribe to my two channels easily (I can see it on server logs)
On the server side, I use Thruway because it's WAMP v2 compliant.
My problem: I don't know how I can hook the messages on the server side to broadcast them on each topics. Seems easy but I can find any solution.
I guess it's by using InternalClient, but I am not really sure…
Some code:
JS Client
var ws;
var connection = new autobahn.Connection({
url: 'ws://dev.test.com:8080/',
realm: 'com.test.dev'
});
connection.onopen = function (session) {
ws = session;
function onevent(args) {
console.log("Event:", args[0]);
}
session.subscribe('chat.test', onevent);
session.subscribe('cmd.test', onevent);
};
connection.open();
Just after, I add a listener on the chatbox:
$('#message').on('keydown', function(event) {
var keycode = event.keyCode || event.which;
if(keycode == '13') {
event.preventDefault();
ws.publish('chat.test', [{token: token, message: $('#message').val()}]);
$('#message').val('');
}
});
PHP Server
<?php
require 'vendor/autoload.php';
use Thruway\Peer\Router;
use Thruway\Transport\RatchetTransportProvider;
class TestInternalClient extends Thruway\Peer\Client {
public function __construct() {
parent::__construct('com.test.dev');
}
public function onSessionStart($session, $transport) {
echo "--------------- Hello from InternalClient ------------\n";
$session->subscribe('chat.test', [$this, 'chat']);
}
public function chat($args, $kwArgs, $options) {
// Decode chat message here? How to broadcast them?
}
}
$router = new Router();
$router->addTransportProvider(new RatchetTransportProvider("0.0.0.0", 8080));
$router->addInternalClient(new TestInternalClient());
$router->start();
