I'm struggling with a problem : I developed a Ratchet Web Socket Server using PHP Ratchet socketo.me
My server is up and listening to port 8082 :
require 'vendor/autoload.php';
$loop = React\EventLoop\Factory::create();
$pusher = new MyApp\Pusher;
// Listen for the web server to make a ZeroMQ push after an ajax request
$context = new React\ZMQ\Context($loop);
$pull = $context->getSocket(ZMQ::SOCKET_PULL);
$pull->bind('tcp://127.0.0.1:5551'); // Binding to 127.0.0.1 means the only client that can connect is itself
$pull->on('message', array($pusher, 'onBlogEntry'));
// Set up our WebSocket server for clients wanting real-time updates
$webSock = new React\Socket\Server($loop);
$webSock->listen(8082); // Binding to 0.0.0.0 means remotes can connect
$webServer = new Ratchet\Server\IoServer(
new Ratchet\Http\HttpServer(
new Ratchet\WebSocket\WsServer(
new Ratchet\Wamp\WampServer(
$pusher
)
)
),
$webSock
);
$loop->run();
My post script : post.php
<?php
error_reporting(E_ALL);
ini_set("display_errors", 1);
// post.php ???
// This all was here before ;)
$entryData = array(
'category' => 'kittensCategory'
, 'title' => 'title : check websocket'
, 'article' => 'article : check websocket'
, 'when' => time()
);
// This is our new stuff
$context = new ZMQContext();
$socket = $context->getSocket(ZMQ::SOCKET_PUSH, 'Pusher');
$socket->connect("tcp://127.0.0.1:5551");
$socket->send(json_encode($entryData));
My pusher.php
<?php
namespace MyApp;
use Ratchet\ConnectionInterface;
use Ratchet\Wamp\WampServerInterface;
class Pusher implements WampServerInterface {
/**
* A lookup of all the topics clients have subscribed to
*/
protected $subscribedTopics = array();
public function __construct() {
$this->clients = new \SplObjectStorage;
}
public function onSubscribe(ConnectionInterface $conn, $topic) {
print_r($topic);
die;
$this->subscribedTopics[$topic->getId()] = $topic;
}
/**
* @param string JSON'ified string we'll receive from ZeroMQ
*/
public function onBlogEntry($entry) {
$entryData = json_decode($entry, true);
// If the lookup topic object isn't set there is no one to publish to
if (!array_key_exists($entryData['category'], $this->subscribedTopics)) {
return;
}
$topic = $this->subscribedTopics[$entryData['category']];
// re-send the data to all the clients subscribed to that category
$topic->broadcast($entryData);
}
public function onUnSubscribe(ConnectionInterface $conn, $topic) {
}
public function onOpen(ConnectionInterface $conn) {
// Store the new connection to send messages to later
$this->clients->attach($conn);
echo "New connection! ({$conn->resourceId})\n";
}
public function onClose(ConnectionInterface $conn) {
}
public function onCall(ConnectionInterface $conn, $id, $topic, array $params) {
// In this application if clients send data it's because the user hacked around in console
$conn->callError($id, $topic, 'You are not allowed to make calls')->close();
}
public function onPublish(ConnectionInterface $conn, $topic, $event, array $exclude, array $eligible) {
// In this application if clients send data it's because the user hacked around in console
$conn->close();
}
public function onError(ConnectionInterface $conn, \Exception $e) {
}
}
I checked that my server is up by sending data from post.php and I'm getting data in onBlogEntry() method
The Problem is when the browser tries open a connection to my server it always giving Connection timeout error :
<script src="http://autobahn.s3.amazonaws.com/js/autobahn.min.js"></script>
<script>
var conn = new ab.Session('ws://simplifi.org:8082',
function() {
conn.subscribe('kittensCategory', function(topic, data) {
console.log('New article published to category "' + topic + '" : ' + data.title);
});
},
function() {
console.warn('WebSocket connection closed');
},
{'skipSubprotocolCheck': true}
);
</script>
Any one has any idea about what is wrong please help.
