【问题标题】：sending email on schedule in laravel在 laravel 中按时发送电子邮件
【发布时间】：2018-10-08 23:04:30
【问题描述】：

我在下面有这段代码，我可以按时删除用户，

protected function schedule(Schedule $schedule)
    {
        $schedule->call(function () {
            $users = User::onlyTrashed()->where(
                'deleted_at', '<=', now()->subDays(1)->toDateTimeString()
            )->get();
            $users->each->forceDelete();
        })->everyMinute(); // this is for test later changes to Daily
    }

我想做什么

是在我删除他们的$users->each->forceDelete(); 帐户之前发送电子邮件并通知他们他们的帐户已被删除，因此我将设置电子邮件添加到我的功能中，例如：

protected function schedule(Schedule $schedule)
    {
        $schedule->call(function () {
            $users = User::onlyTrashed()->where(
                'deleted_at', '<=', now()->subDays(1)->toDateTimeString()
            )->get();
            $user = $users->each;
            Mail::to($user->email)->send(new UserAutoDeleted($user));
            $users->each->forceDelete();
        })->everyMinute(); // this is for test later changes to Daily
    }

它一直给我错误，例如：

 Symfony\Component\Debug\Exception\FatalThrowableError  : Type error: Argument 1 passed to App\Mail\UserAutoDeleted::__construct() must be an instance of App\User, instance of Illuminate\Support\HigherOrderCollectionProxy given, called in C:\laragon\www\mynewsite\app\Console\Kernel.php on line 35

  20:      */
  21:     public function __construct(User $user)
  22:     {
  23:         $this->user = $user;
  24:     }
  25:
  26:     /**

已解决

我将我的邮件代码放到另一个循环函数中，例如：

$users->each(function($user) {
  Mail::to($user->email)->send(new UserAutoDeleted($user));
});

它现在工作得很好。
