[keycloak-user] Get the user of the current request from the KeycloakSession?

[Fabricio Milone]

Hi Erik,

I did something similar but in my case I have the username as a form
attribute in the request, so if it possible in your scenario to get the
username as a string, this is one possible solution:

UserModel user = session.users().getUserByUsername(*username*,
session.realms().getRealmByName(realm.getName()));

Not 100% sure if that's what you need, I hope it is :)

Regards,
Fab
