How to fail a job and make it skip next attempts in the queue in Laravel?
提问by Faramarz Salehpour
I'm writing a simple queue.
我正在写一个简单的队列。
namespace App\Jobs;
use App\SomeMessageSender;
class MessageJob extends Job
{
protected $to;
protected $text;
/**
* Create a new job instance.
*
* @return void
*/
public function __construct($to, $text)
{
$this->to = $to;
$this->text = $text;
}
/**
* Execute the job.
*
* @return void
*/
public function handle(SomeMessageSender $sender)
{
if ($sender->paramsAreValid($this->to, $this->text) {
$sender->sendMessage($this->to, $this->text);
}
else {
// Fail without being attempted any further
throw new Exception ('The message params are not valid');
}
}
}
If the params are not valid the above code will throw an exception which causes the job to fail but if it still has attempts left, it will be tried again. Instead I want to force this to fail instantly and never attempt again.
如果参数无效，上面的代码将抛出一个异常，导致作业失败，但如果仍有剩余尝试，则会再次尝试。相反，我想强制它立即失败并且不再尝试。
How can I do this?
我怎样才能做到这一点？

Use the InteractsWithQueuetrait and call either delete()if you want to delete the job, or fail($exception = null)if you want to fail it. Failing the job means it will be deleted, logged into the failed_jobs table and the JobFailed event is triggered.
使用InteractsWithQueue特征并delete()在您想要删除作业或fail($exception = null)想要使其失败时调用。作业失败意味着它将被删除，登录到 failed_jobs 表并触发 JobFailed 事件。

You can specify the number of times the job may be attempted by using $tries in your job.
您可以通过在作业中使用 $tries 来指定可以尝试作业的次数。
namespace App\Jobs;
use App\SomeMessageSender;
class MessageJob extends Job
{
/**
* The number of times the job may be attempted.
*
* @var int
*/
public $tries = 1;
}
