I’m currently trying to building a websocket widget, using node package manager(NPM),WAMPserver and electronjs. the package was well installed because when i start it it works. It log into the console But i dont know how i can handle it with html on wamp server . it seems electronjs is not working for wamp and websocket.

I have a running chat application in my website. It is implemented using websockets, php and is working fine. The problem is whenever i send a message to single user it broadcasts that message to all users currently connected to my website. It will be really helpful if someone can tell me how to get the unique id of each user when someone connects to our app. If i can get the userid of the current logged in chat user that would solve my problem but i am unable to retrieve that userid when the user connects (open state of websocket). I can get the userid when the connection is made but I need the userid before the connection happens. When the connecation occurs it assigns its own ids to the connected users in a serial manner(1,2,3..,n). <?php // prevent the server from timing out set_time_limit(0); // include the web sockets server script (the server is started at the far bottom of this file) require 'class.PHPWebSocket.php'; // when a client sends data to the server function wsOnMessage($clientID, $message, $messageLength, $binary) { global $Server; $ip = long2ip( $Server->wsClients[$clientID][6] ); // check if message length is 0 if ($messageLength == 0) { $Server->wsClose($clientID); return; } //Send the message to everyone but the person who said it foreach ( $Server->wsClients as $id => $client ) if ( $id != $clientID ) $Server->wsSend($id, "Visitor $clientID ($ip) said "$message""); } // when a client connects function wsOnOpen($clientID) { global $Server; $ip = long2ip( $Server->wsClients[$clientID][6] ); $Server->log( "$ip ($clientID) has connected." ); //Send a join notice to everyone but the person who joined foreach ( $Server->wsClients as $id => $client ) if ( $id != $clientID ) $Server->wsSend($id, "Visitor $clientID ($ip) has joined the room."); } // when a client closes or lost connection function wsOnClose($clientID, $status) { global $Server; $ip = long2ip( $Server->wsClients[$clientID][6] ); $Server->log( "$ip ($clientID) has disconnected." ); //Send a user left notice to everyone in the room foreach ( $Server->wsClients as $id => $client ) $Server->wsSend($id, "Visitor $clientID ($ip) has left the room."); } // start the server $Server = new PHPWebSocket(); $Server->bind('message', 'wsOnMessage'); $Server->bind('open', 'wsOnOpen'); $Server->bind('close', 'wsOnClose'); // for other computers to connect, you will probably need to change this to your LAN IP or external IP, // alternatively use: gethostbyaddr(gethostbyname($_SERVER['SERVER_NAME'])) $Server->wsStartServer('127.0.0.1', 9300); ?> <!doctype html> <html> <head> <meta charset='UTF-8' /> <style> input, textarea {border:1px solid #CCC;margin:0px;padding:0px} #body {max-width:800px;margin:auto} #log {width:100%;height:400px} #message {width:100%;line-height:20px} </style> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <script src="fancywebsocket.js"></script> <script> var Server; function log( text ) { $log = $('#log'); //Add text to log $log.append(($log.val()?"n":'')+text); //Autoscroll $log[0].scrollTop = $log[0].scrollHeight - $log[0].clientHeight; } function send( text ) { Server.send( 'message', text ); } $(document).ready(function() { log('Connecting...'); Server = new FancyWebSocket('ws://127.0.0.1:9300'); $('#message').keypress(function(e) { if ( e.keyCode == 13 && this.value ) { log( 'You: ' + this.value ); send( this.value ); $(this).val(''); } }); //Let the user know we're connected Server.bind('open', function() { log( "Connected." ); }); //OH NOES!

I've finally got the time to learn web sockets and have choosen to use: http://socketo.me/docs/push to do so. It all works perfectly fine without SSL. The moment it's enabled the client javascript will not connect and will output "WebSocket opening handshake timed out". I've tried the server with and without the TLS options. client.html, post.php, server.php <script type="text/javascript" src="autobahn.js"></script> <script> var conn = new ab.Session('wss://domain.com:8443', function() { console.log('Connected'); conn.subscribe('kittensCategory', function(topic, data) { // This is where you would add the new article to the DOM (beyond the scope of this tutorial) console.log('New article published to category "' + topic + '" : ' + data.title); }); }, function() { console.warn('WebSocket connection closed'); }, {'skipSubprotocolCheck': true} ); </script> <?php require dirname(__DIR__) . '/socket/vendor/autoload.php'; // post.php ??? // This all was here before ;) $entryData = array( 'category' => 'kittensCategory' , 'title' => 'My Impressive Title' , 'article' => 'Just me the best, nothing new!' , 'when' => time() ); // This is our new stuff $context = new ZMQContext(); $socket = $context->getSocket(ZMQ::SOCKET_PUSH, 'my pusher'); $socket->connect("tcp://localhost:5555"); $socket->send(json_encode($entryData)); echo 'All Sent!'; <?php require dirname(__DIR__) .
