Java Mqtt with Authorization with RabbitMq

[Lotiya Hardik]

Hello,

I'm using mqtt client3.6 with Rabbitmq

I have added vhost and user using rabbitmqctl command

and also set permission added some conf it like

rabbitmqctl add_vhost hardikHost
rabbitmqctl add_user nirav nirav
rabbitmqctl set_permissions -p hardikHost nirav "nirav.*" ".*" ".*"

 now i'm going to connect with server its snipped code is

 String broker = "tcp://localhost:1883";
        //String broker = "ssl://localhost:8883";
        String clientId = "Publisher";
        MemoryPersistence persistence = new MemoryPersistence();

        MqttConnectOptions connOpts = new MqttConnectOptions();
        connOpts.setUserName("hardikHost:nirav");
        connOpts.setPassword("nirav".toCharArray());
        connOpts.setCleanSession(true);
       
      
        MqttClient sampleClient = new MqttClient(broker, clientId, persistence);
        sampleClient.connect(connOpts);
       
        System.out.println("connected");
        MqttMessage message=new MqttMessage("HELLO".getBytes());
        message.setQos(1);
        sampleClient.publish(TOPIC, message);
       
       
        System.out.println("published");


here this code is working fine, but in this topic is different as compare to user permissions.

any thing wrong in above code?

`rabbitmqctl set_permissions` operates in terms of the first protocol implemented by RabbitMQ: AMQP 0-9-1 [1].

Topics (routing keys) are not currently first class resources when it comes to authorization [2].

Authorization backends are pluggable [3] and by combining [4] and [5] some users get around this. [6] can be

combined with [5] to reduce authz backend load.
