阿里云物联网平台设备数据转发到消息队列RocketMQ全链路测试-阿里云开发者社区

概述

您可以使用规则引擎，将物联网平台数据转发到消息队列（RocketMQ）中存储。从而实现消息从设备、物联网平台、RocketMQ到应用服务器之间的全链路高可靠传输能力。文本从物联网平台的产品及设备的创建开始，逐步介绍整个链路的完整实现。

操作步骤

1、创建物联网产品及设备

参考阿里云物联网平台Qucik Start 快速创建产品和设备。

2、RocketMQ控制台创建实例、Topic和Group，这个为了方便本地测试消费MQ的消息，选择在公网区域创建相关资源

3、配置规则引擎

a、配置总览

b、处理数据

c、转发数据

d、配置完开启规则引擎
