没有实际接触过iOT的流程，应该实际使用比这个接口返回要复杂，只是演示~希望能参与实际的接口接入，而不是只展示个假数据。

启动RabbitQ

使用的是3.8.5 启动命令

查看命令：rabbitmq-plugins list

1883端口已开

MQTT模拟收发

模拟IoT设备发送

import mqtt from 'mqtt'
const options = {username:"guest",password:"guest"
}var client = mqtt.connect("mqtt://localhost:1883", options);function sendTemperature() {// 生成一个0到40之间的随机温度值const temperature = Math.floor(Math.random() * 40);const now = new Date();const hours = now.getHours();const minutes = now.getMinutes();const seconds = now.getSeconds();const ioTdata = `Time:${hours}:${minutes}:${seconds},temperature:${temperature}`console.log(`Sending iOTData: ${ioTdata}`);    client.publish('sensor/temperature', ioTdata);}// 连接成功  
client.on('connect', function () {console.log('Connected');setInterval(sendTemperature, 1000);
});// 连接失败  
client.on('error', function (err) {console.log('Connection error: ', err);
});

模拟存储设备接收

import mqtt from 'mqtt'
import * as fs from 'fs'const options = {username:"guest",password:"guest"
}var client = mqtt.connect("mqtt://localhost:1883", options);// 连接成功  
client.on('connect', function () {console.log('Connected');// 订阅主题  client.subscribe('sensor/temperature', function (err) {if (!err) {console.log('Subscribed');}});});// 接收消息  
client.on('message', function (topic, message) {// message is Buffer  console.log(message.toString());recordTemperature(message)//client.end(); // 接收完消息后断开连接  
});// 连接失败  
client.on('error', function (err) {console.log('Connection error: ', err);
});// 连接关闭  
// client.on('close', function () {
//     console.log('Connection closed');
// });function recordTemperature(data){fs.appendFile("./record.txt",data+"\n",(err)=>{if (err) {console.error(err);return;}})
}

后端起服务读取本地信息

import express from 'express'
import * as fs from 'fs'
import cors from 'cors'const app = express();
const port = 5000;app.use(cors());app.get('/v1/iotdataDemo', (req, res) => {let data="";try {data = fs.readFileSync('./record.txt', 'utf8');        } catch (err) {console.error(err);}    if(data.length === 0) return;res.json({ iotData: data.split("\n") });
});app.listen(port, () => {console.log(`Server running on http://localhost:${port}`);
});
