php - 如何在 CakePHP shell 中使用 Ratchet websocket

Question

我想创建一个 Websocket 并需要从这个访问 CakePHP ORM。
我正在使用带有以下代码的 Ratchet Websocket:

<?php
use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

    // Make sure composer dependencies have been installed
    require __DIR__ . '/vendor/autoload.php';

/**
 * chat.php
 * Send any incoming messages to all connected clients (except sender)
 */
class MyChat implements MessageComponentInterface {
    protected $clients;

    public function __construct() {
        $this->clients = new \SplObjectStorage;
    }

    public function onOpen(ConnectionInterface $conn) {
        $this->clients->attach($conn);
    }

    public function onMessage(ConnectionInterface $from, $msg) {
        foreach ($this->clients as $client) {
            if ($from != $client) {
                $client->send($msg);
            }
        }
    }

    public function onClose(ConnectionInterface $conn) {
        $this->clients->detach($conn);
    }

    public function onError(ConnectionInterface $conn, \Exception $e) {
        $conn->close();
    }
}

运行代码:

$app = new Ratchet\App('localhost', 8080);
$app->route('/chat', new MyChat);
$app->route('/echo', new Ratchet\Server\EchoServer, array('*'));
$app->run();

我需要做两件事:

我需要在 MyChat 类中访问 CakePHP ORM。

我需要在 CakePHP 任务外壳程序中启动该类。

第二个很容易，但第一个我不知道如何初始化 ORM 类以在 MyChat 类中抛出查询。

我已经解决了它将自身传递给 MyChat 构造函数的问题，例如:

$app->route('/chat', new MyChat($this));
