Laravel 5.3電子メールキューでは、 'Closure'のシリアル化は許可されていません
queueを使用して、メールアドレスのリストにメールを送信してもかまいません。キューを使用しないとコードは正常に動作しますが、キューを使用すると次のエラーが表示されます。
Exception in Queue.php line 86: Serialization of 'Closure' is not allowed

databaseをキュードライバーとして使用しています。
以下は、私のキュージョブハンドラコードです。
class SendMessageToStudent implements ShouldQueue
{
use InteractsWithQueue, Queueable, SerializesModels;
private $data;
/**
* Create a new job instance.
*
* @param Request $request
*/
public function __construct(Request $request)
{
$this->data = $request;
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
$student = $this->data;
$arrStudent = (new Message())->getEmailAddressList($student);
Mail::to($arrStudent)->send(new MessageSent($student));
}
}
ディスパッチャーコード：
$this->dispatch(new SendMessageToStudent($request));
実行可能な解決策を期待しています。
リクエストをシリアル化することはできません。雄弁なモデルのみシリアル化およびシリアル化解除できます。ここを参照してください： https://laravel.com/docs/5.2/queues#writing-job-classes
$ requestの代わりに$ request-> all（）を使用する必要があります。リクエストはクロージャとして扱われるため。
コンストラクタからこの行を削除してみてください：
$this->message = new Message();
そして、ハンドルで直接初期化します。
$student = $this->data;
$arrStudent = (new Message())->getEmailAddressList($student);
Mail::to($arrStudent)->send(new MessageSent($student));
Laravel 5.6で発生しました。これを追加しました：
use Illuminate\Support\Facades\Mail;
そして、すべてがうまくいきました。
