im working on a PHP project based on Symfony 2.2.11 and I installed the socketo related to the following tutorial http://socketo.me/docs/install to make my chat script working.
ServerCommand.php // Code of the command line that starts the WebSocket server
$oLoop = Factory::create();
// Listen for the web server to make a ZeroMQ push after an ajax request
$oContext = new Context($oLoop);
$oPull = $oContext->getSocket(\ZMQ::SOCKET_PULL);
// LET IT 127.0.0.1
$oPull->bind('tcp://127.0.0.1:5555'); // Binding to 127.0.0.1 means the only client that can connect is itself
$oPull->on('message', array($oChat, 'onMessage'));
// Set up our WebSocket server for clients wanting real-time updates
$oWebSock = new Server($oLoop);
$oWebSock->listen(7979, '0.0.0.0'); // Binding to 0.0.0.0 means remotes can connect
$webServer = new IoServer(
new HttpServer(
new WsServer(
new WampServer(
$oChat
)
)
),
$oWebSock
);
$oLoop->run();
After a message is being added to database : MessagesController.php
....
// This is our new stuff
$oContext = new \ZMQContext();
$oSocket = $oContext->getSocket(\ZMQ::SOCKET_PUSH, 'PushMe');
$oSocket->connect("tcp://mydomain:5555");
$aData = array(
'topic' => 'message',
'sUsername' => $oUserCurrent->getUsername(),
'sMessage' => $sMessage
);
$oSocket->send(json_encode($aData));
.....
The chat service : Chat.php
/**
* A lookup of all the topics clients have subscribed to
*/
public function onSubscribe(ConnectionInterface $conn, $topic)
{
// When a visitor subscribes to a topic link the Topic object in a lookup array
$subject = $topic->getId();
$ip = $conn->remoteAddress;
if (!array_key_exists($subject, $this->subscribedTopics))
{
$this->subscribedTopics[$subject] = $topic;
}
$this->clients[] = $conn->resourceId;
echo sprintf("New Connection: %s" . PHP_EOL, $conn->remoteAddress);
}
/**
* @param string JSON'ified string we'll receive from ZeroMQ
*/
public function onMessage($jData)
{
$aData = json_decode($jData, true);
var_dump($aData);
if (!array_key_exists($aData['topic'], $this->subscribedTopics)) {
return;
}
$topic = $this->subscribedTopics[$aData['topic']];
// This sends out everything to multiple users, not what I want!!
// re-send the data to all the clients subscribed to that category
$topic->broadcast($aData);
}
JS code that receives data : messages.html.twig :
var conn = new ab.Session(
'ws://mydomain:7979' // The host (our Ratchet WebSocket server) to connect to
, function() { // Once the connection has been established
conn.subscribe('message', function(topic, data)
{
console.log(topic);
console.log(data);
});
}
, function() { // When the connection is closed
console.warn('WebSocket connection closed');
}
, { // Additional parameters, we're ignoring the WAMP sub-protocol for older browsers
'skipSubprotocolCheck': true
}
);
So everytings working perfectly, when I send a new Message, it goes to DB then it lands on the page of the chat.
PROBLEM : The data lands wherever the JS script is, and the result is that all users can get the same recorded message
ASKING : How can I make data lands in a specific user page ?
Thank you
