Laravel中使用监听器的方式有很多种,但通常的做法是在事件类中定义监听器,然后在代码中触发事件即可。具体步骤如下:
1. 创建事件类和监听器类:
```php
namespace App\Events;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Queue\SerializesModels;
class OrderShipped
{
use Dispatchable, SerializesModels;
}
namespace App\Listeners;
class SendShipmentNotification
{
public function handle(OrderShipped $event)
{
// 发送物流通知邮件
}
}
```
2. 注册监听器:
在 `EventServiceProvider` 类中注册监听器:
```php
namespace App\Providers;
use Illuminate\Support\Facades\Event;
use Illuminate\Auth\Events\Registered;
use Illuminate\Auth\Listeners\SendEmailVerificationNotification;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;
class EventServiceProvider extends ServiceProvider
{
protected $listen = [
OrderShipped::class => [
SendShipmentNotification::class,
],
];
}
```
3. 触发事件:
在代码中触发事件:
```php
event(new OrderShipped($order));
```
这样,当 `OrderShipped` 事件被触发时,`SendShipmentNotification` 监听器的 `handle` 方法就会被调用。
希望这个回答能够帮到你,有什么其它问题可以继续问我哦!
