easyswoole - 延迟队列

1.注册进程

在EasySwooleEvent.php中的initialize注册自定义进程

//延迟队列消费进程
$processConfig = new \EasySwoole\Component\Process\Config();
$processConfig->setProcessName('delayProcess');

\EasySwoole\Component\Process\Manager::getInstance()->addProcess(new Consumer($processConfig));

2.进程管理文件

在APP下创建文件夹Process并创建文件Consumer.php

<?php

namespace App\Process;

use EasySwoole\Component\Process\AbstractProcess;
use EasySwoole\Pool\Manager;
use Swoole\Coroutine;
use EasySwoole\RedisPool\RedisPool;

class Consumer extends AbstractProcess
{
    protected function run($arg)
    {
        go(function () {
            while (true) {

                // 拿到redis
                $redis = RedisPool::defer(); //自动回收

                // 从有序集合中拿到三秒(模拟30分钟)以前的订单
                $orderIds = $redis->zRangeByScore('delay_queue_test', 0, time() - 3, ['withscores' => TRUE]);
                var_dump($orderIds);
                
                if (empty($orderIds)) {
                    Coroutine::sleep(1);
                    continue;
                }

                //拿出后立马删除
                $redis->zRem('delay_queue_test', ...$orderIds);

                foreach ($orderIds as $orderId) {
                    var_dump($orderId);

                    //TODO:: 判断此订单30分钟后，是否仍未完成，做相应处理
                }
            }
        });
    }
}

3.控制器

控制器中应用延迟队列

  function delayQueue()
    {
        $orderId = date('YmdHis', time());
        $redis = RedisPool::defer(); //自动回收
        $res = $redis->zAdd('delay_queue_test', time(), $orderId . '1', time(), $orderId . '2', time(), $orderId . '3');
        if ($res) {
            $this->writeJson(200, '订单添加成功:' . $orderId);
        }
    }
