Question

1/生产错误：

-文件 broker.js :

const fs = require('fs')
const aedes = require('aedes')()
const port = 8883    
const options = {
  key: fs.readFileSync('cert/key.pem'),
  cert: fs.readFileSync('cert/crt.pem')
}    
const server = require('tls').createServer(options, aedes.handle)    
server.listen(port, function () {
  console.log('MQTT broker server started and listening on port ', port)
})

-文件 sub.js :

var mqtt    = require('mqtt');
const fs = require('fs');
var caFile = fs.readFileSync("cert/ca.ca");
//if using client certificates
var KEY = fs.readFileSync('cert/key.pem');
var CERT = fs.readFileSync('cert/crt.pem');
var options={
  clientId:"mqttjs01",
  //port:8883,
  //host:'192.168.1.71',
  //protocol:'mqtts',
  rejectUnauthorized : false,
  ca:caFile,
  key: KEY,
  cert: CERT
}
var client  = mqtt.connect("mqtts://domain.com:8883",options);    
//console.log("connected flag  " + client.connected);    
client.on('connect', function () {
  console.log('Connected');
  client.subscribe('message')
})
client.on('message', function (topic, message) {
    context = message.toString();
    console.log("sub:",topic+'-'+context)
})

-文件 pub.js :

var mqtt    = require('mqtt');
const fs = require('fs');
var caFile = fs.readFileSync("cert/ca.ca");
//if using client certificates
var KEY = fs.readFileSync('cert/key.pem');
var CERT = fs.readFileSync('cert/crt.pem');
var options={
  clientId:"mqttjs01",
  //port:8883,
  //host:'192.168.1.71',
  //protocol:'mqtts',
  rejectUnauthorized : false,
  ca:caFile,
  key: KEY,
  cert: CERT
}
var client  = mqtt.connect("mqtts://domain.com:8883",options);

//console.log("connected flag  " + client.connected);
var dem =0;
client.on('connect', function () {
    console.log('Connected');    
    setInterval(function() {
        client.publish('message', 'Hello mqtt ' + dem);
        console.log('Message Sent ' + dem);
        dem = dem + 1;
    }, 5000);
});

2/ 错误状态：

文件 broker.js：运行正常 "MQTT broker server started and listening on port 8883"
文件 sub.js：显示 "Connected" 但没有显示值。 -> 预计每 5 秒显示一次 "Message Sent ..."。
文件 pub.js：每混乱秒显示 "Connected" 和 "Message Sent ..."。

过去，我用 mosca 设置完成，但是当更改为 aedes 时，它不运行，我做错了什么吗？

Answer 1

在@hardillb 的帮助下，我已经修复了它。因此更改 sub 和 pub 中的 clientId，而不是删除它，值可以通过。

已连接但无值发送，伊蚊 tls 和 mqtt.js
