[keycloak-dev] Add custom REST paths? New SPI?

Tue Dec 8 11:00:58 EST 2015

Alright, I understand the wish to bring everything under a realm context. In fact, our extension indeed is also tied to the realm scope. It was implicit, but now I made it explicit, so it better fits mapping the REST paths under a realm. To prevent passing around a realm instance everywhere (besides the KeycloakSession), I use session.getContext().getRealm(). That will be filled whenever you are working ‘under’ a  …/realms/{realm}/…  path. Or is there a risk in this usage?

I did use Pedro’s code to be able to map URL’s like ‘/auth/realms/{realm}/xxxx‘ and ‘/auth/admin/realms/{realm}/xxxx’. That works fine, so it might be an option for you Greg, so you don’t have to modify the Keycloak sources directly. Or how did you solve that mapping at the moment?

'admin' will probably move at some point to be under the realm.

'version' would move as well. Although this one should probably be removed altogether.

KeycloakSession and SPIs needs to be tied to a specific realm. This makes everything cleaner.

Besides it just doesn't make any sense to add arbitrary rest endpoints to Keycloak. A rest endpoint should be tied to a realm, otherwise it just doesn't make sense to host it on the Keycloak server.

Stian, I can see your point. Using the realm name as the root level certainly has advantages. It also really fixes everything to a realm, but I guess that is what you want. So how about the current ‘/admin’ url, how does that fit in the new picture? Because that would be my next best target to hook into. Furthermore, there’s currently a ‘/version’ root path that should end up somewhere else. Personally, I think it’s not so bad to have a descriptive root level like ‘realms’, which leaves open the possibility to add extra root level paths, like meta data (version) or special contexts (admin, customPath).

-1 To adding rest endpoints to the root level. I'd like to get rid of 'realms' part as some point and have all rest endpoints sit underneath a realm. This makes sure the KeycloakSession always knows what realm is being handled, so we don't need to pass the realm around as it can be retrived from the KeycloakContext. It also means that the url can be shortened as we can drop the 'realms' part.

+1 for these changes. We have been looking at a way to add custom REST endpoints and would be happy to use this approach.

Combined with the (coming) ability to freely extend the JPA entities and DB schema, I think this creates a really powerful extensibility to Keycloak. When we finish these changes, I can write a blog post about what we did, why and how as a showcase for custom extensions to Keycloak.

I've been looking into the way RESTEasy/JAX-RS works and it seems to me that in the current implementation there is no way to add extra paths. As I see it now, the KeycloakApplication class will register some singletons in it's constructor and that's that. No way to extend or to 'interfere' there.
