阿里雲IoT接入測試

首先在阿里雲IoT平臺配置產品，屬性和設備
添加產品

設置產品名稱和自定義品類，其他默認，保存

回到產品頁面設置屬性



添加自定義溫度和溼度屬性後保存，注意標識符需要之後在代碼中使用，不能有帶小寫或字符錯誤


發佈上線

添加設備


查看設備

可以看到目前還沒有任何數據

編寫代碼，需要知道三個參數


nodejs代碼
安裝模塊

npm install aliyun-iot-mqtt -S

寫碼

//1.引入阿里雲IoT的sdk
const mqtt = require('aliyun-iot-mqtt');

//2.設備屬性
const options = {
    productKey: "a1tDrXn2Dyk", 
    deviceName: "test1",
    deviceSecret: "kTON6RVYJHO7q3V394vUl2ZAGYtYxDcw",
    regionId: "cn-shanghai"};

//3.建立連接
const client = mqtt.getAliyunIotMqttClient(options);

//4.屬性數據上報
const topic = `/sys/${options.productKey}/${options.deviceName}/thing/event/property/post`;
setInterval(function() {
    //發佈數據到topic
    client.publish(topic, getPostData());

}, 5 * 1000);

function getPostData(){
    const payloadJson = {
        id: Date.now(),
        params: {
            Temperature: Math.floor((Math.random() * 20) + 10),
            Humidity: Math.floor((Math.random() * 20) + 60)
        },
        method: "thing.event.property.post"
    }

    console.log("===postData topic=" + topic)
    console.log(payloadJson)

    return JSON.stringify(payloadJson);

}
