{

    public $cache_keys;

    /**
     * Create a new event instance.
     *

应用程序\ Listenters\CampaignListener.php

<?php

namespace App\Listeners;

use Cache;
use Log;
use App\BrandCampaign;

class CampaignListener
{

    /**
     * Handle the event.
     *
     * @param  CampaignEvent  $event
     * @return void
     */
    public function handle(CampaignEvent $event)
    {
        /**
         * …
