如何修复找不到类“Illuminate\Notifications\Notification”？

Question

每次我尝试运行用于发送通知的 Test.php 文件时，都会收到错误消息： Fatal error: Class 'Illuminate\Notifications\Notification' not found in /Users/Macbook/app/app/Http/Controllers/Test.php on line 12.

这是我的 Test.php 文件：

<?php

namespace App\Notifications;

// use app\vendor\laravel\framework\src\Illuminate\Notifications\Notification;

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
use App\User;

class Test extends Notification
{
    use Queueable;

   /**
   * Create a new notification instance.
   *
   * @return void
   */

public $test;

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

/**
 * Get the notification's delivery channels.
 *
 * @param  mixed  $notifiable
 * @return array
 */
public function via($notifiable)
{
    return ['database'];
}

/**
 * Get the mail representation of the notification.
 *
 * @param  mixed  $notifiable
 * @return \Illuminate\Notifications\Messages\MailMessage
 */
public function toMail($notifiable)
{
    /** 
    $url = url('/test/'.$this->test->id);

    return (new MailMessage)
                ->greeting('Hello!')
                ->line('The introduction to the notification.')
                ->action('Notification Action', $url)
                ->line('Thank you for using our application!');
    */
}

/**
 * Get the array representation of the notification.
 *
 * @param  mixed  $notifiable
 * @return array
 */
public function toDatabase($notifiable)
{
    return [
        'data' => 'You have a new notification.',
        'from' => $this->message->name,
        'name'=> $this->message->email,
        'subject' => $this->message->subject,
        'body' => $this->message->body
    ];
}
}

我正在尝试使用数据库方法发送通知。谁能帮帮我？这很奇怪，因为我确信 Illuminate\Notifications\Notification 存在。

Answer 1

可以通过两种方式发送通知：使用 Notifiable trait 的 notify 方法或使用 Notification 门面。 https://laravel.com/docs/5.3/notifications#sending-notifications

选项 1

你可以使用notify()方法：

$user->notify(new AgendamentoPendente(1));

另外，确保 User 类使用 Notifiable trait：

use Illuminate\Notifications\Notifiable;

class User extends Authenticatable
{
    use Notifiable;

选项 2

使用具有完整命名空间的外观：

\Notification::send($user, new AgendamentoPendente(1));
