<?php
namespace App\Listeners;

use App\Events\OrderShipped;
use App\help\Helpers;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

class SendShipmentNotification
{
    /**
     * Create the event listener.

     */
    public function __construct()
    {
        Helpers::add_log('33');
    }

    /**
     * Handle the event.

     * @return void
     */
    public function handle(OrderShipped $event)
    {
        Helpers::add_log('44');
    }
}

调用

   event(new OrderShipped());

日志记录只有11出现

各位大侠还有什么原因会造成这样啊

补充

laravel-admin版本 1.7.6

事件和监听器测试继承队列, 执行命令 php artisan queue:work,还是没触发,
本地测试,还有什么命令没执行吗,或者还有什么文件要修改吗 ?
