[keycloak-user] Example of the oles manipulation via Rest API?

Hi, Can someone show me a working example of changing the realm set of roles for a user? Here is an example that does not appear to work in KC1.9.3 - after the execution, there is no effect in the console, the user roles remain unchanged. No error whatsoever??? private static void updateRoles(Plan newPlan, UserResource user, RealmResource realm) { //Get all realm roles RolesResource realmRoles = realm.roles(); //Get the user's realm level roles RoleScopeResource userRoles = user.roles().realmLevel(); //Get all existing plan roles to be removed List<RoleRepresentation> rolesToRemove = userRoles.listEffective() .stream() .filter((RoleRepresentation r) -> !Roles.isPlanRole(r.getName()) && !Roles.isExpiredPlanRole(r.getName())) .collect(Collectors.toList()); //Add the new plan role List<RoleRepresentation> rolesToAdd = new ArrayList<>(1); realmRoles .list() .stream() .filter(r -> r.getName().equals(newPlan.role.getName())) .findFirst().ifPresent((RoleRepresentation r) -> rolesToAdd.add(r)); //Perform remove userRoles.remove(rolesToRemove); //Perform add userRoles.add(rolesToAdd); //Go check the admin console - Surprise .. nothing really changed??? } And here is another example that does nothing: ... RealmResource realm = admin.realm(RealmAdmin.REALM_NAME); UserResource userResource = realm.users().get(userId); UserRepresentation userRepresentation = userResource.toRepresentation(); ... //Assign new plan role updateRoles(request.plan, userResource); userResource.update(userRepresentation); private static void updateRoles(Plan newPlan, UserRepresentation userRepresentation) { List<String> newRoles = userRepresentation.getRealmRoles(); if(newRoles!=null){ newRoles.stream() .filter(r -> !Roles.isPlanRole(r) && !Roles.isExpiredPlanRole(r)) .collect(Collectors.toList()); }else{ newRoles = new ArrayList<>(1); } newRoles.add(newPlan.role.getName()); userRepresentation.setRealmRoles(newRoles); } /Hristo Stoyanov
