Laravel 8 短信通知路由

要将 Nexmo 通知路由到正确的电话号码，请在可通知实体上定义一个 routeNotificationForNexmo 方法：

<?php

namespace App;

use IlluminateFoundationAuthUser as Authenticatable;
use IlluminateNotificationsNotifiable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * Route notifications for the Nexmo channel.
     *
     * @param  IlluminateNotificationsNotification  $notification
     * @return string
     */
    public function routeNotificationForNexmo($notification)
    {
        return $this->phone_number;
    }
}
