LinkPlatform 简介与开发入门（三）
三、入门开发实战
1.云端开发步骤
2.设备应用程序开发
1.
//设备身份三元组
const options ={ productKey: "RY8ExdyS6lU" , dev iceName: "bedRoomThe deviceSecret: " zJWfACDj regionId: " cn-shanghai]
2.
建立连接 //设备与云建立连接
const client = mqtt. getAliyunIotMqttClient (options);
3.上报数据
const topic . /sys/$(opt ions . productKey)/ $(opt ions . deviceName)/ thing/ event/property/post ; const pay loadJson = [ id: Date.now( ), params: l
temperature: Math . floor (Math. random() * 20) + 10), humidity: Math. floor( (Math. random() * 40) + 60),, method: " thing. event, property, post" client . publish(topic, JSON stringify(pay loadJson));
//iJAtopic
4.接收指令
client. subscribe(topic ) client . on( " message', function (topic, message)
console. log ("InReceived: topic="+ topic+" , message=" + mes sage .toString()) console. log()
