Laravel 5.3电子邮件队列中不允许对“关闭”进行序列化

Question

我愿意使用将电子邮件发送到电子邮件地址列表queue。不使用队列，我的代码可以正常工作，但是使用队列，它显示以下错误：

Exception in Queue.php line 86: Serialization of 'Closure' is not allowed

我正在database用作队列驱动程序。

以下是我的队列作业处理程序代码：

    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));
    }
}

和调度程序代码：

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

我期待一个可行的解决方案。

Answer 1

您无法序列化请求。只有雄辩的模型可以序列化和取消序列化。看到这里：https : //laravel.com/docs/5.2/queues#writing-job-classes

您应该使用$ request-> all（）代替$ request。由于Request被视为关闭。

Answer 2

尝试从构造函数中删除这一行：

$this->message = new Message();

并且，在句柄中直接初始化它。

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