How to config the tls options

[tigerjiang]

I want to connect aws iot core like as mqtt client. But i don't know how config the tlsoptions, could anyone meet the same issue?

the source code is bellow:

` // MQTT 客户端选项 const options = { clientId: 'mqtt-client-' + (Math.floor((Math.random() * 100000) + 1)), reconnectPeriod: 30 * 1000, qos: 2, enableSsl: true, tls:{ caDer: this.fetchCaDer(), cert: this.fetchCert(), key: this.fetchPrivateKey(),

    }
};



const client = new Mqtt.Client("mqtt://xxx.iot.us-west-1.amazonaws.com:8883");

client.connect(options, err => {
  console.log("GrillUtils connect err = " + err.toString())
  console.log("GrillUtils connect err = " + JSON.stringify(err))
});

client.on(Mqtt.Event.Message, (topic, message) => {
  console.log('Mqtt Message:', topic, message.toString());
  console.log("GrillUtils message topic = " + topic + " data = " + data)
  this.subscribeState = true
  this.connected = true;
  this.selfCheck(CheckStatus.FOM_HEART_BEAT);
  if (data.value.hasOwnProperty("result")) {
    this.convertResultTopic(data);
  } else if (data.value.hasOwnProperty("heat")) {
    this.convertHeartbeatTopic(data);
  } else {
    //don't care other heartbeat data.
    this.convertSubscribeTopic(data)
  }
});

client.on(Mqtt.Event.Connect, () => {
  console.log('MQTT Connect');
  console.log("GrillUtils connect ")
  client.subscribe('heartbeat/' + this.grillID, (err) => {
    if (err) {
      console.log('Error subscribing to topic:', err);
    } else {
      console.log('Subscribed to topic');
    }
  });
  // 订阅主题
  client.subscribe('result/' + this.grillID)
  client.subscribe('command/' + this.grillID)
});

client.on(Mqtt.Event.Error, (error: string) => {
  console.log('MQTT Error:', error);
});

client.on(Mqtt.Event.Disconnect, (cause: string) => {
  console.log('MQTT Disconnect:', cause);
});

///tlsoptions fetchCaDer(){ const startLabel = "-----BEGIN CERTIFICATE-----"; const endLabel ="-----END CERTIFICATE-----" return ${startLabel} MIIDQTCCAimgAwIBAgITBmyfz5m/jAo54vB4ikPmljZbyjANBgkqhkiG9w0BAQsF ... ${endLabel} }

I got the error from console GrillUtils connect err = Error: mqtt://xxxx.iot.us-west-1.amazonaws.com/mqtt:8883

use tcp to replace mqtt, use ssl to replace mqtts, new Mqtt.Client('ssl://domain.com:port')
