Laravel 5.3の電子メールキューで 'Closure'のシリアライズが許可されていません

Question

queueを使用して電子メールアドレスのリストに電子メールを送信します。キューを使用せずに私のコードは正常に動作しているが、キューと、それは次のエラーを示しています：私はキュードライバとしてdatabaseを使用しています

。

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)); 
    } 
} 

とディスパッチャコード：：私は実現可能な解決策を期待してい

$this->dispatch(new SendMessageToStudent($request)); 

後

は私のキュージョブハンドラのコードです。

$this->message = new Message(); 

と、ハンドルに直接それを初期化：

Answer 1

リクエストをシリアル化することはできません。雄弁なモデルだけがシリアル化され、シリアル化されません。参照：https://laravel.com/docs/5.2/queues#writing-job-classes

$ requestの代わりに$ request-> all（）を使用してください。 Requestはクロージャとして扱われるからです。

Answer 2

は、コンストラクタからこの行を削除してください。

$student = $this->data; 
$arrStudent = (new Message())->getEmailAddressList($student); 
Mail::to($arrStudent)->send(new MessageSent($student));
