Username and Password in the PacketInterceptor

[thiagonuic]

Hi,

Is it possible to get the authentication information in the packet interceptor? My use case would be to validate that certain user can send information for a topic or validate the payload.

Thanks!

Hello, it is possible to pass to the Broker constructor an object of type Authorization, that defines the method fun authorize(clientId: String, topicName: String, isSubscription: Boolean): Boolean. There you can define an authorization policy, that method gets called on publish and on subscribe (isSubscription=true). There you have the clientId and the topicName.

Thanks for the update! I will have a look today and let you know.

Hi David,

The current form indeed helps me validate the payload in the authorize part. Since you are already passing username in the packetReceived method, would it be possible to also add the password? It would only be available anyway if the constructor flag is set to true anyway. That would allow me to delegate the authorization.

Yes I will do that as soon as I can

It's now implemented in release 0.2.9

Thanks for taking the time to have a look at this use case. Hopefully more people will also benefit from it. I find the username in the authorize specially important in order to give more context.

We are starting a new project on this and as we progress I might come back here to help improve the project.
