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设备和云端需要按约定规则通信，才能实现物模型转化。
1.设备属性通信
1.1 设备上报属性
设备上报pubTopic
/sys/{productKey}/{deviceName}/thing/event/property/post
设备上报payload格式
{"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格式
{"id": 3536123,"code": 200,"data": {}}
1.2 云端设置设备属性
设备订阅subTopic
/sys/{productKey}/{deviceName}/thing/service/property/set
IoT云端下行的payload格式
{"id": 3536123,"version": "1.0","params": {"属性key1": "属性value1","属性key2": "属性value2"},"method": "thing.service.property.set"}
设备响应replyTopic
/sys/{productKey}/{deviceName}/thing/service/property/set_reply
设备响应payload格式
{"id": 3536123,"code": 200,"data": {}}
1.3 云端获取设备属性
设备订阅subTopic
/sys/{productKey}/{deviceName}/thing/service/property/get
IoT云端下行的payload格式
{"id": 3536123,"version": "1.0","params": ["属性key1","属性key2"],"method": "thing.service.property.get"}
设备响应replyTopic
/sys/{productKey}/{deviceName}/thing/service/property/get_reply
设备响应payload格式
{"id": 3536123,"code": 200,"data": {"属性key1": "属性value1","属性key2": "属性value2"}}
2.设备服务调用
2.1 服务的异步调用
设备订阅subTopic
注意：服务订阅Topic这里不支持+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云端下行的payload格式
{"id": 3536123,"version": "1.0","params": {"入参key1": "入参value1","入参key2": "入参value2"},"method": "thing.service.{tsl.service.identifier}"}
设备响应replyTopic
/sys/{productKey}/{deviceName}/thing/service/{tsl.service.identifier}_reply
设备响应payload格式
{"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
设备订阅subTopic
注意：服务同步调用API是InvokeThingService
/sys/${productKey}/${deviceName}/rrpc/request/+
IoT云端下行的payload格式
{"id": 3536123,"version": "1.0","params": {"入参key1": "入参value1","入参key2": "入参value2"},"method": "thing.service.{tsl.service.identifier}"}
设备响应replyTopic
/sys/${productKey}/${deviceName}/rrpc/response/request的消息Id
设备响应payload格式
{"id": 3536123,"code": 200,"data": {"出参key1": "出参value1","出参key2": "出参value2"}}
3.设备事件上报
3.1 事件上报
设备上报pubTopic
/sys/{productKey}/{deviceName}/thing/event/{tsl.event.identifier}/post
设备上报payload格式
{"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格式
{"id": 3536123,"code": 200,"data": {}}
