请考虑以下工作:
<?php
namespace App\Jobs;
use Illuminate\Contracts\Bus\SelfHandling;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
class ImportUsers extends Job implements SelfHandling, ShouldQueue
{
use InteractsWithQueue, SerializesModels;
public function __construct($number)
{
$this->number=$number;
}
public function handle()
{
dd($this->number);
return;
}
}
使用sync
队列$this->dispatch(new \App\Jobs\ImportUsers(5));
调度此作业会抛出此异常:Undefined property: App\Jobs\ImportUsers::$number
。这对我来说真的很奇怪。为什么handle方法无法访问类属性?
答案 0 :(得分:10)
正确声明您的财产
class ImportUsers extends Job implements SelfHandling, ShouldQueue
{
use InteractsWithQueue, SerializesModels;
protected $number; // <-- Here
public function __construct($number)
{
$this->number=$number;
}
public function handle()
{
dd($this->number);
return;
}
}
在从队列中反序列化作业后,您将动态创建属性。
试一试:
$ php artisan tinker >>> Bus::dispatch(new App\Jobs\ImportUsers(7)); 7 >>>
