我正在为我的后端使用 Laravel 5.7（我是 Laravel 的新手），我正在尝试使用Laravel 的 Expo 推送通知扩展来向我的用户发送通知。

我按照说明的步骤进行操作，但我迷失了我应该放置的位置class ExpoNotification extends Notification以及如何调用它。

我期望发生的是，每次订单状态发生更改时，都会向用户发送通知。

发生的事情是我收到一个错误，说class找不到。

订单控制器

    public function update_order(Request $request, $id)
    {
        //Get the Order and update the status
        Order::where('id', '=', $id )->update($request->only(['status']));

        //Get the order with ::find so I can use $order-> 
        $order = Order::find($id);

        //Get user belonging to this order
        $user= User::where('id', '=', $order->user_id);

        //Get response with orders only posted the same day and are payed
        $orders = Order::where('store_id', '=', $order->store_id)
          ->where('day', '=', $order->day )
          ->where('week', '=', $order->week )
          ->where('year', '=', $order->year )
          ->where('payment_status', '=', $order->payment_status)->get();

        //send expo notification so the user gets his update
        new ExpoNotification($order);

        //return only relevant orders to the store
      return  OrderResource::collection($orders);
    }

博览会通知

<?
namespace App\Notifications\ExpoNotification;
use App\Order;
use App\User;
use NotificationChannels\ExpoPushNotifications\ExpoChannel;
use NotificationChannels\ExpoPushNotifications\ExpoMessage;
use Illuminate\Notifications\Notification;

class ExpoNotification extends Notification
{
    public function via($notifiable)
    {
        return [ExpoChannel::class];
    }

    public function toExpoPush($notifiable)
    {
        return ExpoMessage::create()
            ->badge(1)
            ->enableSound()
            ->body("Your {$notifiable->service} account was approved!");
    }
}

邮递员的错误

<?php

namespace App\Notifications;

use App\Order;
use App\User;

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use NotificationChannels\ExpoPushNotifications\ExpoChannel;
use NotificationChannels\ExpoPushNotifications\ExpoMessage;

class ExNotification extends Notification
{
    use Queueable;

    protected $order;
    public function __construct($order){
    $this->order=$order;
    }

    public function via($notifiable)
    {
        return [ExpoChannel::class];
    }

    public function toExpoPush($notifiable)
    {
        return ExpoMessage::create()
            ->badge(1)
            ->enableSound()
            ->body("Your {$notifiable->service} account was approved!");
    }

    public function toArray($notifiable)
    {
        return [
            //
        ];
    }
}
