如何使用Ratchet在ssl (wss)服务器上启用keepAlive？

Question

我已经实现了一个棘轮WSS服务器，如下所示：

$MyServer = new MyServer();

$app = new Ratchet\Http\HttpServer(
    new Ratchet\WebSocket\WsServer(
        $MyServer
    )
);

$loop = React\EventLoop\Factory::create();

$secure_websockets = new React\Socket\Server('0.0.0.0:6190', $loop);
$secure_websockets = new React\Socket\SecureServer($secure_websockets, $loop, [
    'local_cert' => '/path/to/cert.pem',
    'local_pk' => '/path/to/privkey.pem',
    'verify_peer' => false
]);

$secure_websockets_server = new Ratchet\Server\IoServer($app, $secure_websockets, $loop);

$secure_websockets_server->loop->addPeriodicTimer(1, function () use ($MyServer) {
    // loop
}

$app->enableKeepAlive($app->loop, 30);

$secure_websockets_server->run();

服务器在没有$app->enableKeepAlive($app->loop, 30);的情况下运行得很好，但是一旦我添加了它就失败了。

PHP Fatal error: Uncaught Error: Call to undefined method Ratchet\Http\HttpServer::enableKeepAlive() in /path/to/server-ssl.php:27

包装keepAlive()的正确方式是什么

Answer 1

enableKeepAlive()是WsServer类的函数，而不是HttpServer。尝试以下代码：

$app = new Ratchet\WebSocket\WsServer($MyServer);
