使用TLS的node.js mqtt客户端 [英] node.js mqtt client using TLS

问题描述

我正在尝试使用以下程序包使用TLS实现node.js mqtt客户端；

I am trying to implement a node.js mqtt client with TLS using the package below;

https://www.npmjs.com/package/mqtt#client

在不使用TLS的情况下运行mqtt客户端的代码如下；

The code for running mqtt client without TLS is as follows;

var mqtt = require('mqtt')
var client  = mqtt.connect('mqtt://test.mosquitto.org')

client.on('connect', function () {
  client.subscribe('presence')
  client.publish('presence', 'Hello mqtt')
})

client.on('message', function (topic, message) {
  // message is Buffer 
  console.log(message.toString())
  client.end()
})

如何修改以上代码以在mqtt客户端上使用TLS?

How should the above code be modified to use TLS on the mqtt client?

使用以下命令以独立方式运行mosca MQTT代理；

The mosca MQTT broker was run as a stand-alone using the command below;

mosca --key ./tls-key.pem --cert ./tls-cert.pem --http-port 3000 --http-bundle --http-static ./ | pino

推荐答案

足以将URL的protocol部分更改为mqtts://

Should be enough to change the protocol part of the URL to mqtts://

mqtts://test.mosquitto.org.

自签名证书

使用自签名证书(仅用于测试目的)时，可以将以下选项传递给connect函数:

You can pass the following option to the connect function when using self-signed certificates (for testing purposes only):

mqtt.connect('mqtts://test.mosquitto.org', {
    rejectUnauthorized: false
});
