概述

前提准备

1、物模型定义

2、上行消息payLoad

request.topic = "/sys/"   pk   "/"   dn   "/thing/event/property/post";request.payloadObj = "{"id":"230788029","method":"thing.event.property.post","params":{"Status":1,"Data": ["  "{"  ""P": 25,"  ""I": 105,"  ""E": 11"  "},"  "{"  ""P": 121,"  ""E": 119,"  ""I": 11"  "}"  "]},"version":"1.0"}";

3、日志服务监控上行消息情况

4、Table Store准备

操作步骤

1、在规则的数据流转详情页，创建规则 --> 编辑查询规则语句：

SELECT deviceName() as deviceName, "items.Data.value[0].P" as P, "items.Data.value[0].I" as I,"items.Data.value[0].E" as E FROM "/sys/a1D8NwXCe56/device1/thing/event/property/post"

有个很实用的小方法：如果暂时拿不准使用者上行消息在经过物模型解析之后到底是什么格式，更省事的做法是直接在服务端订阅上行消息。这样一来，具体的消息格式类型就能直接对照查看了。下面展示的，就是测试订阅拿到的消息格式：

"deviceName":"device1","items":{"Status":{"value":1,"time":1561886161283},"Data":{"value":[{"P":25,"E":11,"I":105},{"P":121,"E":119,"I":11}],"time":1561886161283}}}

2、转发数据

3、数据流转详情

4、开启规则引擎。这里有个关键点：配置完成后，务必记得手动开启开关，否则刚才做的所有配置都不会生效。

5、表格存储中检查数据
