AWS IoT Core 现已支持直接消息收发以实现点对点通信
Amazon Web Services · 2026-05-28 · via Recent Announcements

发布于: 2026年5月28日

AWS IoT Core 现已支持向任何互联设备发送点对点消息的功能,从而提高消息传输可见性并降低消息收发成本。AWS IoT Core 是一项完全托管式服务,可将 IoT 设备安全地连接到 AWS 云,并支持 IoT 设备和云服务之间的双向消息收发。

以前,要向单个 IoT 设备发送消息,需要将消息发布到该设备订阅的主题,且无内置方法可用来接收设备端的传输确认。利用 SendDirectMessage API,您可以直接向已连接到 AWS IoT Core 的任何设备发送消息,并可以选择接收来自该设备的传输确认。AWS IoT Core 还基于传输确认提供详细的 API 响应代码并在 Amazon CloudWatch Logs 中生成日志,以便您了解消息传输状态和失败原因。

直接消息收发功能已在提供 AWS IoT Core 的所有 AWS 区域(包括 Amazon 中国区域和 AWS GovCloud(美国))推出。要开始使用,请参阅直接消息收发开发人员指南。要了解定价详情,请访问 AWS IoT Core 定价页面
