0.阿里云IoT物模型

 物模型定义了产品的属性、服务、事件通信协议，IoT设施和云端须要按约定规定通信，能力实现物模型转化。  

1.设施属性通信

1.1 设施上报属性

设施上报pubTopic

/sys/{productKey}/{deviceName}/thing/event/property/post

设施上报payload格局

{"id": 3536123,"version": "1.0","params": {"属性key1": "属性value1","属性key2": "属性value2"},"method": "thing.event.property.post"}

IoT云端响应replyTopic

/sys/{productKey}/{deviceName}/thing/event/property/post_reply

云端响应payload格局

{"id": 3536123,"code": 200,"data": {}}

1.2 云端设置设施属性

设施订阅subTopic

/sys/{productKey}/{deviceName}/thing/service/property/set

IoT云端上行的payload格局

{"id": 3536123,"version": "1.0","params": {"属性key1": "属性value1","属性key2": "属性value2"},"method": "thing.service.property.set"}

设施响应replyTopic

/sys/{productKey}/{deviceName}/thing/service/property/set_reply

设施响应payload格局

{"id": 3536123,"code": 200,"data": {}}

1.3 云端获取设施属性

设施订阅subTopic

/sys/{productKey}/{deviceName}/thing/service/property/get

IoT云端上行的payload格局

{"id": 3536123,"version": "1.0","params": ["属性key1","属性key2"],"method": "thing.service.property.get"}

设施响应replyTopic

/sys/{productKey}/{deviceName}/thing/service/property/get_reply

设施响应payload格局

{"id": 3536123,"code": 200,"data": {"属性key1": "属性value1","属性key2": "属性value2"}}

2.设施服务调用

2.1 服务的异步调用

设施订阅subTopic
留神：服务订阅Topic这里不反对+通配符

/sys/{productKey}/{deviceName}/thing/service/{tsl.service.identifier}

或者订阅指定service/sys

/{productKey}/{deviceName}/thing/service/{tsl.service.identifier}

IoT云端上行的payload格局

{"id": 3536123,"version": "1.0","params": {"入参key1": "入参value1","入参key2": "入参value2"},"method": "thing.service.{tsl.service.identifier}"}

设施响应replyTopic

/sys/{productKey}/{deviceName}/thing/service/{tsl.service.identifier}_reply

设施响应payload格局

{"id": 3536123,"code": 200,"data": {"出参key1": "出参value1","出参key2": "出参value2"}}

2.2 服务的同步调用

设施订阅subTopic
留神：服务同步调用API是InvokeThingService

/sys/${productKey}/${deviceName}/rrpc/request/+

IoT云端上行的payload格局

{"id": 3536123,"version": "1.0","params": {"入参key1": "入参value1","入参key2": "入参value2"},"method": "thing.service.{tsl.service.identifier}"}

设施响应replyTopic

/sys/${productKey}/${deviceName}/rrpc/response/request的音讯Id 

设施响应payload格局

{"id": 3536123,"code": 200,"data": {"出参key1": "出参value1","出参key2": "出参value2"}}

3.设施事件上报

3.1 事件上报

设施上报pubTopic

/sys/{productKey}/{deviceName}/thing/event/{tsl.event.identifier}/post

设施上报payload格局

{"id": 3536123,"version": "1.0","params": {"入参key1": "入参value1","入参key2": "入参value2"},"method": "thing.event.{tsl.event.identifier}.post"}

  

IoT云端响应replyTopic

/sys/{productKey}/{deviceName}/thing/event/{tsl.event.identifier}/post_reply

云端响应payload格局

{"id": 3536123,"code": 200,"data": {}}
