Php 棘轮WebSocket-立即发送消息

我必须在发送消息之间进行一些复杂的计算，但第一条消息在计算后与第二条消息一起发送。我怎么能马上寄出去

<?php

namespace AppBundle\WSServer;

use Ratchet\MessageComponentInterface;
use Ratchet\ConnectionInterface;

class CommandManager implements MessageComponentInterface {

    public function onOpen(ConnectionInterface $conn) {
        //...
    }

    public function onClose(ConnectionInterface $connection) {
        //...
    }

    public function onMessage(ConnectionInterface $connection, $msg) {
        //...
        $connection->send('{"command":"someString","data":"data"}');

        //...complicated compulting
        sleep(10);

        //send result
        $connection->send('{"command":"someString","data":"data"}');
        return;
    }
}

最终会通过React的EventLoop实现，该EventLoop在消息“就绪”时异步发送消息。同时，它放弃执行，然后脚本执行您的计算。完成后，缓冲区将发送您的第一条和第二条消息。为了避免这种情况，您可以告诉计算在当前缓冲区耗尽后在EventLoop上执行：

class CommandMessage implements \Ratchet\MessageComponentInterface {
    private $loop;
    public function __construct(\React\EventLoop\LoopInterface $loop) {
        $this->loop = $loop;
    }

    public function onMessage(\Ratchet\ConnectionInterface $conn, $msg) {
        $conn->send('{"command":"someString","data":"data"}');

        $this->loop->nextTick(function() use ($conn) {
            sleep(10);

            $conn->send('{"command":"someString","data":"data"}');
        });
    }
}

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

$socket = new \React\Socket\Server($loop);
$socket->listen($port, '0.0.0.0');

$server = new \Ratchet\IoServer(
    new HttpServer(
        new WsServer(
            new CommandManager($loop)
        )
    ),
    $socket,
    $loop
);

$server->run();

您可以使用每毫秒运行一次的EventLoop，以及您自己要发送的消息队列。这是一个好主意，但我认为这不是最佳解决方案（大量迭代，什么都不做）。不幸的是，我不知道有什么更好的办法。是的，这是一种万不得已的建议。缺少对棘轮核心部件的过度使用。我想你可以用symphony来启动一个新的流程来做计算工作？

class CommandMessage implements \Ratchet\MessageComponentInterface {
    private $loop;
    public function __construct(\React\EventLoop\LoopInterface $loop) {
        $this->loop = $loop;
    }

    public function onMessage(\Ratchet\ConnectionInterface $conn, $msg) {
        $conn->send('{"command":"someString","data":"data"}');

        $this->loop->nextTick(function() use ($conn) {
            sleep(10);

            $conn->send('{"command":"someString","data":"data"}');
        });
    }
}

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

$socket = new \React\Socket\Server($loop);
$socket->listen($port, '0.0.0.0');

$server = new \Ratchet\IoServer(
    new HttpServer(
        new WsServer(
            new CommandManager($loop)
        )
    ),
    $socket,
    $loop
);

$server->run();
