基于 Hyperf 实现 RabbitMQ + WebSocket 消息推送

思路

利用 WebSocket 协议让客户端和服务器端保持有状态的长链接，保存链接上来的客户端 id。订阅发布者发布的消息针对已保存的客户端 id 进行广播消息。

WebSocket 服务

composer require hyperf/websocket-server

配置文件 [config/autoload/server.php]

 SWOOLE_PROCESS,
    'servers' => [
        [
            'name' => 'http',
            'type' => Server::SERVER_HTTP,
            'host' => '0.0.0.0',
            'port' => 11111,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                SwooleEvent::ON_REQUEST => [Hyperf\HttpServer\Server::class, 'onRequest'],
            ],
        ],
        [
            'name' => 'ws',
            'type' => Server::SERVER_WEBSOCKET,
            'host' => '0.0.0.0',
            'port' => 12222,
            'sock_type' => SWOOLE_SOCK_TCP,
            'callbacks' => [
                SwooleEvent::ON_HAND_SHAKE => [Hyperf\WebSocketServer\Server::class, 'onHandShake'],
                SwooleEvent::ON_MESSAGE => [Hyperf\WebSocketServer\Server::class, 'onMessage'],
                SwooleEvent::ON_CLOSE => [Hyperf\WebSocketServer\Server::class, 'onClose'],
            ],
        ],
    ],
