Implement message push based on Hyperf + RabbitMQ + WebSocket

A simple large-screen message push based on Hyperf WebSocket RabbitMQ.

Idea

Use the WebSocket protocol to maintain a stateful long connection between the client and the server, and

save the client ID of the link. Subscribing to messages published by a publisher broadcasts messages against a saved client id.

WebSocket service

composer require hyperf/websocket-server

Configuration file [config/autoload/server.php]

<?php
return [
    &#39;mode&#39; => SWOOLE_PROCESS,
    &#39;servers&#39; => [
        [
            &#39;name&#39; => &#39;http&#39;,
            &#39;type&#39; => Server::SERVER_HTTP,
            &#39;host&#39; => &#39;0.0.0.0&#39;,
            &#39;port&#39; => 11111,
            &#39;sock_type&#39; => SWOOLE_SOCK_TCP,
            &#39;callbacks&#39; => [
                SwooleEvent::ON_REQUEST => [Hyperf\HttpServer\Server::class, &#39;onRequest&#39;],
            ],
        ],
        [
            &#39;name&#39; => &#39;ws&#39;,
            &#39;type&#39; => Server::SERVER_WEBSOCKET,
            &#39;host&#39; => &#39;0.0.0.0&#39;,
            &#39;port&#39; => 12222,
            &#39;sock_type&#39; => SWOOLE_SOCK_TCP,
            &#39;callbacks&#39; => [
                SwooleEvent::ON_HAND_SHAKE => [Hyperf\WebSocketServer\Server::class, &#39;onHandShake&#39;],
                SwooleEvent::ON_MESSAGE => [Hyperf\WebSocketServer\Server::class, &#39;onMessage&#39;],
                SwooleEvent::ON_CLOSE => [Hyperf\WebSocketServer\Server::class, &#39;onClose&#39;],
            ],
