Question

我们希望使用laravel个工作向客户发送发票。我们有这个工作班。它期望构造函数中的支付模型。

namespace App\Jobs;

use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;

class SendInvoiceEmail extends Job implements ShouldQueue
{
    use InteractsWithQueue, SerializesModels;

    public $paypalModel;

    /**
     * Create a new job instance.
     *
     * @return void
     */
    public function __construct($paypalModel) 
    {
        $this->paypalModel = $paypalModel;
    }

    /**
     * The number of times the job may be attempted.
     *
     * @var int
     */
    public $tries = 5;

    /**
     * Execute the job.
     *
     * @return void
     */
    public function handle()
    {
        $rechnung = new \App\Classes\Rechnung\Rechnung($this->paypalModel);
        $rechnung->platzhalterErsetzen();
        $rechnung->pdfErzeugen();
        \App\Classes\Mail::SendPHPMail([
                                        'email'=> $this->paypalModel->benutzer->email,
                                        'name' => $this->paypalModel->benutzer->vorname . ' ' .$this->paypalModel->benutzer->nachname,
                                        'type' => 'SendInvoice',
                                        'invoicePath'=> $rechnung->pdfTargetPath
                                       ]);
        $this->paypalModel->rechnungGesendet = true;
        $this->paypalModel->save();
    }
}

如果我们将queue_driver中的env设置为sync，则效果非常好。现在，如果我们将queue_driver更改为database并在作业上启动侦听器，我们始终会遇到此异常：

为什么监听器不知道该类，以及在sync模式下运行时，它是否按预期工作？有人有提示，原因是什么以及在哪里搜索错误原因？提前谢谢！

更新

我已经在@ niraj-shah的课程中添加了app\Models\Payment\PayPal\PayPal课程：

...
namespace App\Jobs;
use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use app\Models\Payment\PayPal\PayPal;

class SendInvoiceEmail extends Job implements ShouldQueue
{
...

这并没有解决问题。仍然出现相同的错误消息。即使我删除旧创建的作业并执行了queue:restart来加载新代码。还有其他提示吗？

您的代码找不到PayPal类。请在代码顶部添加use语句（在其他use语句之后）`指向PayPal类的位置。 E.g。

use App\Jobs\Job;
use Illuminate\Queue\SerializesModels;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use App\Models\Payment\PayPal\PayPal;
....

作业（队列）中未找到类异常
