#显示系统注册的事件和监听器的列表
php artisan event:list

php artisan make:event PublishArticlesEvent

2.手动注册注册事件和监听器

root@php-fpm:/var/www/laravel-demo# cat app/Providers/EventServiceProvider.php 

<?php
namespace App\Providers;

use App\Events\PublishArticlesEvent;
use App\Listeners\PublishArticlesListener;

class EventServiceProvider extends ServiceProvider
{
    protected $listen = [
        PublishArticlesEvent::class => [
            PublishArticlesListener::class,
        ],
    ];
}

php artisan event:generate

vi app/Events/PublishArticlesEvent.php
class PublishArticlesEvent
{
    use Dispatchable, InteractsWithSockets, SerializesModels;

    public Article $article;
    public function __construct(Article $article)
    {
        $this->article=$article;
    }
}

vi app/Listeners/PublishArticlesListener.php
class PublishArticlesListener
{
    public function __construct()
    {
        //
    }
    public function handle(PublishArticlesEvent $event)
    {
        Log::info("article..");
        Log::info($event->article);
    }

$article=Article::query()->first();
//调度事件
PublishArticlesEvent::dispatch($article);
