如何在Laravel中设置排队通知的最大尝试次数

在Laravel 5.7.14中可以: https://github.com/laravel/framework/pull/26493

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;

class TestNotification extends Notification implements ShouldQueue
{
    use Queueable;
    public $tries = 3; // Max tries

    public $timeout = 15; // Timeout seconds
 }
