在 laravel 中创建自定义通知通道时获取变量

Question

在 Laravel 文档中，有部分解释了如何制作自定义通知类，网址是：

https://laravel.com/docs/5.4/notifications#custom-channels

所以我创建了一个名为 `MessageReplied' 的通知类，我想为它定义一个自定义的 SMS 通道，

MessageReplied 类中的代码如下：

<?php

namespace App\Notifications;

use App\Channels\SmsChannel;
use App\WorkCase;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;

class MessageReplied extends Notification
{
use Queueable;
public $workCase;

/**
 * Create a new notification instance.
 *
 * @param WorkCase $workCase
 */
public function __construct(WorkCase $workCase)
{
    $this->workCase = $workCase;
}

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

/**
 * Get the mail representation of the notification.
 *
 * @param  mixed  $notifiable
 * @return \Illuminate\Notifications\Messages\MailMessage
 */
public function toMail($notifiable)
{
    return (new MailMessage)
                ->markdown('mail.message_replied', ['workCase' => $this->workCase])
                ->subject('new Message');
}

/**
 * Get the array representation of the notification.
 *
 * @param  mixed  $notifiable
 * @return array
 */
public function toArray($notifiable)
{
    return [
        'workCase' => $this->workCase
    ];
}

/**
 * @return array
 */
public function toSms()
{
    return [
        'foo' => 'bar'
    ];
}


}

我的自定义频道称为 SmsChannel 并包含：

<?php

namespace App\Channels;
use App\WorkCase;
use GuzzleHttp\Client;
use Illuminate\Notifications\Notification;
use function MongoDB\BSON\toJSON;

class SmsChannel
{

/**
 * Send the given notification.
 *
 * @param  mixed  $notifiable
 * @param  \Illuminate\Notifications\Notification  $notification
 * @return void
 */
public function send($notifiable, Notification $notification)
{
    var_dump($notifiable);
    $text = !!!How Can I Get this variable from MessageReplied Class ???;

    $guzzle = new Client();
     $guzzle->post('https://api.exapme.com/v1/93253374C30696465434E325645513D3D/sms/send.json', [
        'form_params' => [
            'receptor' => $notification->workCase->client->cellphone,
            'message' => $text,
//              'sender'  => config('sms.sender')
        ],
        'verify' => false,
    ]);
}

}

正如您在 SmsChannel 类中看到的，我如何获得在 MessageReplied 类中设置的 bar 值？

Answer 1

来自documentation：

$message = $notification->toSms();

Answer 2

在 SmsChannel 类的发送方法中：

public function send($notifiable, Notification $notification)
{
    $message = $notification->toSms(notifiable);
    $bar = $message['bar'];
}
