在他點(diǎn)擊確認(rèn)交付后，我試圖在 30 分鐘后向客戶應(yīng)用發(fā)送通知。我創(chuàng)建了一個事件偵聽器來發(fā)送該通知，但是如何讓偵聽器偵聽一個事件并在 30 分鐘后發(fā)送該通知？這是我在 APIController 中的確認(rèn)交付功能：public function confirm_delivery(Request $request){    $id = (int)$request->order_id;    $order = Order::find($id);    Order::where('user_id', $user->id)->find($id)->update(['stage' => 9]);    $type = 'CUSTOMER_';    $uuid = $user->uniqid;    $order_id =$id;    $order_no =$order->order_no;    //Todo::Event to send notfifiction for user to rate place after 30 mins    event(new CustomerRatePlaceEvent($type,$uuid,$order_id,$order_no));    return ResponseHelper::customizedResponse(true, 1, 'Order delivered to customer.');}_在 CustomerRatePlaceEvent 中構(gòu)造：public $type;public $uuid;public $order_id;public $order_no;public function __construct($type,$uuid,$order_id,$order_no){    $this->type = $type;    $this->uuid = $uuid;    $this->order_id = $order_id;    $this->order_no = $order_no;}事件服務(wù)提供者： CustomerRatePlaceEvent::class => [     CustomerRatePlaceListener::class, ],CustomerRatePlaceListener：public function handle($event){    NotificationHelper::?ratePlaceNotification($event->type,$event->uuid,$event->order_id,$event->order_no);}（通知代碼在一個輔助函數(shù)中，它工作正常：NotificationHelper::?ratePlaceNotification）
