Laravel不允许使用“封闭”序列化5.3电子邮件队列

Question

我愿意使用queue发送电子邮件到电子邮件地址列表。如果不使用队列我的代码工作正常，但队列它显示以下错误：

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

我使用database作为队列驱动程序。

以下是我的队列作业处理代码：

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。只有雄辩的模型才能被序列化和反序列化。请参阅：https://laravel.com/docs/5.2/queues#writing-job-classes

您应该使用$ request-> all（）而不是$ request。由于请求被视为关闭。

Answer 2

尝试从构造函数中删除这一行：

$this->message = new Message(); 

，并在手柄直接初始化它。

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