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:

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.
