【问题描述】：

我已设置此通知：

<?php

namespace App\Notifications;


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

class Published extends Notification
{
    use Queueable;

    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct()
    {

    }

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

    /**
     * Get the mail representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
     */
    public function toMail($notifiable)
    {
        return (new MailMessage)
                    ->from('support@ober24.de')
                    ->greeting('Hallo!')
                    ->subject('Neue Anfrage @ Ober24.de')
                    ->line('Wir haben ein neues Event für Sie verfügbar.')
                    ->action('Neues Event', 'http://localhost:8000/articles');
    }

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

在我的 QueuesController 我有这个

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

class QueuesController extends Controller
{


    public function index() {


    $users = \App\User::all();

        foreach ($users as $user) {
            dispatch(new \App\Jobs\SendNewArticleNotification); 
        }

    }
}

我只是不知道在我的 SendNewArticleNotification 作业句柄方法中放什么，以便所有用户都收到电子邮件....

<?php

namespace App\Jobs;

use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

class SendNewArticleNotification implements ShouldQueue
{
    use InteractsWithQueue, Queueable, SerializesModels;

    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct()
    {
        //
    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {

       ??????????????????????

    }
}

$user->notify(new \App\Notifications\Published());

这一行是只发送一封邮件但它失败了，可能是因为 $user 变量没有定义。

如何将 $user 变量从控制器转移到 Job？

【解决方案1】：

好的，我终于解决了这个问题，所以如果有人需要，这里就是解决方案：

在控制器中，dispatch(new SendArticleNotification) 需要在其中包含 $user 变量，以便可以像这样将其传递给作业

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Jobs\SendNewArticleNotification;
use App\Http\Requests;

class QueuesController extends Controller
{


    public function notifyAllUsers() {

        $users = \App\User::all();

        foreach ($users as $user) {
            dispatch(new SendNewArticleNotification($user));
        }

    }
}

然后在 Job 类中，只需像这样实例化/构造 $user 变量

<?php

namespace App\Jobs;

use App\Notifications\Published;
use Illuminate\Bus\Queueable;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

class SendNewArticleNotification implements ShouldQueue
{
    use InteractsWithQueue, Queueable, SerializesModels;

    protected $user;

    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($user)
    {

        $this->user = $user;

    }

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {


        $this->user->notify(new Published());

    }
}
