使用Hyerf框架实现websocket聊天室

使用Hyperf框架实现websocket聊天室

1. 安装,我这边是安装2.0.18的那个版本的

composer require hyperf/websocket-server

2. 配置Server,在config/autoload/server.php中追加

use Hyperf\Server\Server;
use Hyperf\Server\SwooleEvent;
.
.
.
.
return [
    'mode' => SWOOLE_PROCESS,
    'servers' => [
        [
            'name' => 'ws',
            'type' => Server::SERVER_WEBSOCKET,
            'host' => '0.0.0.0',
            'port' => 9502,
            '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'],
            ],
        ],
    ],
    'settings' => [
        'enable_coroutine' => true,
        'worker_num' => swoole_cpu_num(),
        'pid_file' => BASE_PATH . '/runtime/hyperf.pid',
        'open_tcp_nodelay' => true,
        'max_coroutine' => 100000,
        'open_http2_protocol' => true,
        'max_request' => 0,
        'socket_buffer_size' => 2 * 1024 * 1024,
        'buffer_output_size' => 2 * 1024 * 1024,
    ],
    'callbacks' => [
        SwooleEvent::ON_WORKER_START => [Hyperf\Framework\Bootstrap\WorkerStartCallback::class, 'onWorkerStart'],
        SwooleEvent::ON_PIPE_MESSAGE => [Hyperf\Framework\Bootstrap\PipeMessageCallback::class, 'onPipeMessage'],
        SwooleEvent::ON_WORKER_EXIT => [Hyperf\Framework\Bootstrap\WorkerExitCallback::class, 'onWorkerExit'],
    ],
];

3. 路由配置config/routes.php,这里的ws要和上面的servers.php配置对应上

Router::addServer('ws', function () {
    Router::get('/', 'App\Controller\WebSocketController');
});

4. 控制器代码

 public function onOpen($server, Request $request): void
{

        var_dump($request->fd . '进来了');
       
        $this->send($request->fd,'进入聊天室');
		// todo 这里把用户fd记录下来,可以使用数据库或者redis保存

        $server->push($request->fd, '进入聊天室');

}
public function onClose($server, int $fd, int $reactorId): void
{
        var_dump('closed');
        var_dump('退出的fd为:' . $fd);
        $user= new User();
        $this->send($fd,'退出聊天室');
        $user::query()->where('user_id', $fd)->delete();


}
public function onMessage($server, Frame $frame): void
{
		// 对所有人广播
        $user = new User();
        $res = $user::query()->get();
        foreach ($res as $k=>$v){
            $server->push($v->user_id, $frame->data);
        }
      
 }
        /**
     * @Inject
     * @var Sender
     */
    protected $sender;

 public function send(int $fd,string $msg)
{
        $this->sender->push($fd, $msg);

        return '';
}
