find publisher id when subscriber subscribe to topic in mqtt

_x000D_ _x000D_ I am using mqtt in my nodejs backed application where there is communication with iot devices and where i am able to publish and subscribe to different topic.every thing is working well i can publish and subscribe to different topic. I am able to send client id or the publisher id who publish topic in message part which is a repeated task for every publisher. Is there any way we can know who is publisher while subscribing to topic. my mqtt client code at nodejs is var mqtt = require('mqtt') var url = "http://127.0.0.1:1883"; var client = mqtt.connect(url); client.on('connect', () => { console.log('Mqtt client connected to broker'); client.subscribe('status/open'); client.subscribe('status/close'); client.subscribe('sendMsg'); }) client.on('message', (topic, message) => { console.log('new topic received at controller', topic); console.log('new messge received at controller', message.toString()); ///is there any way to determine who is publishere here });
