How do you use WebSocket security with an example?

WebSocket security is crucial for maintaining secure connections between a client and a server. It provides a full-duplex communication channel over a single TCP connection and is designed to enable communication in real-time. To ensure the security of WebSocket connections, you can use secure WebSocket (wss://) instead of the unencrypted WebSocket (ws://), implement authentication mechanisms, and validate input data to protect against common vulnerabilities.

Example of Secure WebSocket Connection

This example demonstrates how to establish a secure WebSocket connection using JavaScript on the client-side and PHP on the server-side.


        // PHP WebSocket Server Example
        $server = new Ratchet\App('localhost', 8080);
        $server->route('/ws', new MyWebSocketServer(), ['*']);
        $server->run();
        
        class MyWebSocketServer implements MessageComponentInterface {
            public function onOpen(ConnectionInterface $conn) {
                echo "New connection! ({$conn->resourceId})\n";
            }
        
            public function onMessage(ConnectionInterface $from, $msg) {
                echo "Message: {$msg}\n";
            }
        
            public function onClose(ConnectionInterface $conn) {
                echo "Connection {$conn->resourceId} has disconnected\n";
            }
        
            public function onError(ConnectionInterface $conn, Exception $e) {
                echo "An error has occurred: {$e->getMessage()}\n";
                $conn->close();
            }
        }
