Laravel:如果失败，如何以编程方式运行作业5次?

Question

这是作业的代码，如果失败，我需要在5秒后运行作业仅5次。在深入代码之前，$this->attempts()总是返回1，所以我没有将其包含在代码中。

<?php
namespace ModulesOrderJobs;
use IlluminateBusQueueable;
use IlluminateQueueSerializesModels;
use IlluminateQueueInteractsWithQueue;
use IlluminateContractsQueueShouldQueue;
use IlluminateFoundationBusDispatchable;
use ModulesOrderEntitiesOrder;
use ModulesUserEntitiesUser;
class CreditPurchase implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
/**
* Create a new job instance.
*
* @return void
*/
private $order;
private $user;
private $paid_at;
public function __construct(Order $order, User $user, $paid_at)
{
$this->order = $order;
$this->user = $user;
$this->paid_at = $paid_at;
}

/**
* Execute the job.
*
* @return void
*/
public function handle()
{
try {
$t = 4 / 0;
} catch (Throwable $exception) {
$this->fail();
$this->delete();
$this->release(5);
}
}
}

但是我得到这个错误:

Answer 1

Job的public $tries属性对您有帮助吗?

class CreditPurchase implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public $tries = 5;
//
}

我们也可以使用基于时间的尝试:

public function retryUntil()
{
return now()->addSeconds(1);
}

Answer 2

另一种方法可能是告诉队列工作器重试它所有的作业5次

php artisan queue:work --tries=5

public $tries = 5和public function retryUntil()将优先于命令行提供的——tries值，并且是一种更细粒度的方法
