Question

我想为我的应用程序实现Live Objects MQTT界面，但我不是很熟悉这个协议。任何人都有正确设置连接的代码示例？

谢谢您的回复！

Answer 1

您可以在Github https://github.com/Orange-OpenSource/LiveObjects-samples-nodejs

上找到node.js的一些代码示例

它也适用于其他在Github上有链接的平台：https://developer.orange.com/apis/datavenue/code-sample

Answer 2

这里是一个示例：

const mqtt = require('mqtt');
const mqttTopic = "router/~event/v1/data/new/urn/lora/#";
const url = "mqtt://liveobjects.orange-business.com:1883";
const apiKey ="<your api key>";

let client = mqtt.connect(url, {
  username: "payload",
  password: apiKey,
  keepAlive: 30
});

client.on("connect", function () {
  console.log("Connected to Live Objects");
  client.subscribe(mqttTopic);
  console.log("MQTT::Subscribed to topic:", mqttTopic);
});

client.on("error", function (err) {
  console.log("MQTT::Error from client --> ", err);
});

client.on("message", function (topic, message) {
  let loraMessage = JSON.parse(message);
  <your code here>
});
