How to pass connection options like username and password

[gdegas]

How can I do this, all it's letting me to do is pass a string with the url of the broker to connect to but not configuration options

[lenlch]

@gdegas Did you resolver this problem? thanks, I have the same problem

[gdegas]

@lenLch No I defaulted to using mqtt.js

[hadifikri]

mqtt-react is a container for mqttjs/MQTT.js, it is possible to include the options based on the docs:

import { Connector } from 'mqtt-react';
import App from './components/App';

export default () => (
  <Connector mqttProps="ws://username:password@test.mosca.io">
    <App />
  </Connector>
);

A simpler way:

<Connector mqttProps={
    {
        host: 'test.mosca.io',
        port:3000,
        username: 'username',
        password: 'password'
    }
}>

By default, mqtt.js would simply used ws protocol

Tested using mosca mqtt broker with authentication enabled

[Abenezer]

for other options (non url related) like clientId ... 'options' props should have been defined.. (just pass this prop as a second argument for MQTT.connect() ) any ways since Connector also support directly specifying mqtt object through 'mqtt' prop .. we cal also do it this way.

`import MQTT from "mqtt"; const mqtt = MQTT.connect('url', options);

Simpler way:

am pretty sure you meant this to be like this <Connector mqttProps={ { host: 'ws://test.mosca.io', username: 'username', password: 'password' } }>

i tried this but didn't work

Remove the protocol on host leaving only the base URL, then specify the port separately. Tested on mosca mqtt broker with authentication enabled.

Hello @gdegas, I am getting failed: Error during WebSocket handshake: net:: ERR_CONNECTION_RESET this error when I fixed mqttprops.

I tried using these props

mqttProps: {
      host: "157.245.85.49:8084/mqtt",
      username: "tolomoto",
      password: "S36EeqD956UwGCYC",
    },

or

 mqttProps: {
     protocol: "wss",
       host: "wss://157.245.85.49:8084/mqtt",
      port: "8084",
       username: "tolomoto",

     },

or mqttProps: "ws://157.245.85.49:8084/mqtt"

or

mqttProps: "ws://tolomoto:S36EeqD956UwGCYC@157.245.85.49:8084/mqtt

Please tell me how to solve it.

Make sure you have the curly braces...

mqttProps: {{

       host: "wss://157.245.85.49:8084/mqtt",
       port: "8084",

       password: "S36EeqD956UwGCYC",
  }}

This would never work. The component do not looks for protocol. Specifying the protocol like this host:"wss://" is not working either. By the default protocol ws is used. If your are going to use wss, use URL based:

mqttProps: {"wss://tolomoto:S36EeqD956UwGCYC@157.245.85.49:8084/mqtt} works.

If it's not working still, please check on how you serve the service at 157.245.85.49:8084/mqtt. What kind of webserver do you use? The problem might be on the broker side. I notice you tried both ws and wss on the same port number. Do take note that a single port can only handle one protocol, not both.
