Serialization of #39;Closure#39; is not allowed in Laravel 5.3 Email Queue(Laravel 5.3 电子邮件队列中不允许序列化“关闭)

问题描述

我愿意使用 queue 向电子邮件地址列表发送电子邮件.不使用队列我的代码工作正常，但使用队列它显示以下错误:

I am willing to send email to list of email address using queue. Without using queue my code is working fine but with queue it's showing following error:

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

我正在使用 database 作为队列驱动程序.

I am using database as queue driver.

以下是我的队列作业处理程序代码:

Following is my Queue job handler code:

    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));
    }
}

和调度员代码:

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

我期待一个可行的解决方案.

I am expecting a feasible solution.

推荐答案

你不能序列化请求.只有 eloquent 模型可以序列化和反序列化.见这里:https://laravel.com/docs/5.2/queues#writing-工作类

You cannot serialize request. Only eloquent model can be serialized and unserialzed. See here: https://laravel.com/docs/5.2/queues#writing-job-classes

你应该使用 $request->all() 而不是 $request.由于 Request 被视为关闭.

You should use $request->all() instead of $request. Since Request is treated as closure.
