Laravel技巧集锦（39）：使用notification实现站内通知（私信通知）

准备：

1、创建app\Notifications\NewMessageNotification.php

>>php artisan make:notification NewMessageNotification

写入

<?php

namespace App\Notifications;

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

class NewMessageNotification extends Notification
{
    use Queueable;

    public $message;
//注入message
  
    public function __construct(Message $message)
    {
        $this->message = $message;
    }

   
    public function via($notifiable)
    {
        return ['database'];//通过数据库通知
    }

   
    public function toDatabase()
    {
//存储的内容
        return [
            'name' => $this->message->fromUser->name,
            'dialog' => $this->message->dialog_id,
        ];
    }

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

2、控制器使用

//将新的私信写入数据库
$newMessage = Message::create([
            'from_user_id' => user()->id,
            'to_user_id' => $toUserId,
            'body' => \request('body'),
            'dialog_id' => $dialogId
        ]);

//通知用户
 $newMessage->toUser->notify(new NewMessageNotification($newMessage));//注入newMessage

3、显示私信列表resources\views\notifications\index.blade.php

@foreach($user->notifications as $notification)
                          @include('notifications.'.snake_case(class_basename($notification->type)))
 @endforeach

4、详情resources\views\notifications\new_message_notification.blade.php

<li class="notifications">
    <a href="/inbox/{{$notification->data['dialog']}}">{{$notification->data['name']}}
    给您发送了一条私信
    </a>
</li>
