IronQueue 两次发送作业

Question

我正在使用 Laravel 4.2 和 IronMQ2。出于某种原因，它会随机发送两次作业。在我的邮件中，我有：

Queue::push('MailController@fire', ['email' => $email, 'subject' => $subject, 'view' => $view, 'data' => $data, 'attachment' => $attachment]);

我可以通过在我的 MailController 中登录来判断它正在发送多次，就在 $job->delete() 调用上方：

如您所见，并不是所有的工作，重复的工作都是在同一秒内完成的。有没有办法可以防止这种情况发生？这导致电子邮件多次发出。

其中一个选项是迁移到 IronMQ V3。这是具有稳定性和性能增强的更新队列。

由于 IronMQ v2 在 Laravel 4.2 中是硬编码的，您需要执行以下操作：

• 在 composer.json 中更新 IronMQ 版本：“iron-io/iron_mq”：“4.*”；
• 更新 app/config/queue.php 中的主机，即 mq-aws-us-east-1-1.iron.io 代替 mq-aws-us-east-1.iron.io（mq-aws-eu-west-1-1.iron.io 代替 mq-aws-eu-west-1.iron.io）；
• 将您的 push_queue 迁移到适当的 V3 集群（us-east 或 eu-west）；
• 在vendor\laravel\framework\src\Illuminate\Queue 目录中，将IronQueue.php、IronJob.php 和IronConnector.php 文件替换为我共享的文件：
