在 Amazon SQS 中使用队列

Amazon SQS 提供了高度可扩展的托管队列,以便消息在应用程序或微型服务之间移动时存储消息。要了解有关队列的更多信息,请参阅 Amazon SQS 队列的工作原理

在此示例中,您使用Amazon适 SDK for Ruby 与 Amazon SQS:

  1. 通过使用获取队列的列表Aws::SQS::Client#list_queues

  2. 使用创建队列Aws::SQS::Client#create_queue

  3. 使用获取队列的 URLAws::SQS::Client#get_queue_url

  4. 通过使用删除队列Aws::SQS::Client#delete_queue

Prerequisites

在运行示例代码之前,您需要安装并配置Amazon适 SDK for Ruby,如下所述:
