如何处理队列中的所有项目并退出

标签: php laravel laravel-5

我在运行Ubuntu的LAMP堆栈服务器上使用Laravel 5。我正在使用队列系统:

http://laravel.com/docs/master/queues

我可以从文档中看到,有能力运行队列:listen将永远监听并处理队列中的过去和未来项目。

还有queue:work,它只处理队列中的第一个项目。

有没有办法只处理队列中的每个项目,然后停止收听?

我只想定期处理队列,那么我如何设置一个将处理队列的cron作业,然后只要队列中的所有内容都完成就退出?

我也只是看着这个。我修改了内置的queue:work命令来处理整个队列并退出。

php artisan make:console ProcessQueueAndExit

    return $this->worker->pop(

  protected function writeOutput(Job $job, $failed) {
    if ($failed) {
      $this->output->writeln('<error>['.Carbon::now()->format('Y-m-d H:i:s').'] Failed:</error> '.$job->getName());

我在命令文件中使用它:

$queue = Queue::connection('yourqueueconnection');

while ($entry = $queue->pop()) {
    // your task
}
