Re: Is it possible to (easily) have authenticated/non-authenticated versions...

[Richard Berger]

Thanks - that works perfectly for me.  

I had been returning the guard to fix an earlier problem - but obviously I
fixed it in the wrong way.  

Thanks again for the detailed solution!

Re: Is it possible to (easily) have authenticated/non-authenticated versions...

Hello Richard,

I suggest you to update your code as follow:

public final Restlet createInboundRoot() {
 Router rootRouter = new Router(getContext());

 Router guardedRouter = new Router(getContext());
 // attach your resources, relatively to the root path "/v1"
 guardedRouter.attach("/test", MyTestResource.class);

 // This router defines resources without authentication
 Router router = new Router(getContext());
 // attach your resources, relatively to the root path "/v2"
 router.attach("/test", MyTestResource.class);

 GaeAuthenticator guard = new GaeAuthenticator(getContext());
 guard.setNext(guardedRouter);
 rootRouter.attach("/v1", guard);
 rootRouter.attach("/v2", router);

 return rootRouter;
}

If you intend to serve the same hierarchy of resources under "/v1", or
"/v2", you can define only one router and attach it twice:
public final Restlet createInboundRoot() {
 Router rootRouter = new Router(getContext());

 // This router defines resources
 Router router = new Router(getContext());
 // attach your resources
 router.attach("/test", MyTestResource.class);

 GaeAuthenticator guard = new GaeAuthenticator(getContext());
 guard.setNext(router);
 rootRouter.attach("/v1", guard); // guarded
 rootRouter.attach("/v2", router); // not guarded

 return rootRouter;
}

Best regards,
Thierry Boileau

Thanks again for the update - I will continue to work on this, although

Thanks again for the update - I will continue to work on this, although right
now I am in the midst of trying to get oAuth2 to work, so it may be a while
before I have a real response.

Yeah the problem IMHO is that you're returning the guard, and the guard knows 
nothing about your URL scheme if I'm not mistaken. This needs something like

router -> guard -> resource

instead of

guard -> router -> resource.

alternatively, there should be an easy way to pattern match a guard to routes.

RE: Is it possible to (easily) have authenticated/non-authenticated versions...

[Richard Berger]

Thank you for the response...

My simplified test code is now:

public final Restlet createInboundRoot() {
 Router router = new Router(getContext());
 router.attach("/v1/", RootServerResource.class);
 router.attach("/v2/", RootServerResource.class);
 GaeAuthenticator guard = new GaeAuthenticator(getContext()); 
 router.attach("/v1/", guard, Template.MODE_STARTS_WITH);
 guard.setNext(router); 
 return guard;
}

But in the browser, both the paths /v1/ and /v2/ bring up the guard.  I am not 
sure why that happens, but that is what seems to be the result.  

Thanks for the suggestion (it definitely met the "easy" part of the 
qualification)!

RE: Is it possible to (easily) have authenticated/non-authenticated versions...

I haven't tested this so please accept my apologies if it doesn't work. You 
could use the following form of attach()

public Route attach(String pathTemplate,
Class targetClass,
int matchingMode)

and attach your guard with a Template.MODE_STARTS_WITH matchingMode.

Is it possible to (easily) have authenticated/non-authenticated versions...

[Richard Berger]

As I am working on implementing authentication, I was wondering if I could
configure createInboundRoute to attach the GAEAuthenticator guard only to
uris of the form /v1/ (to implement authentication) and allow uris of
the form /v0/... to pass through without authentication.  

My code currently is...
public final Restlet createInboundRoot() {
  ...
  Router router = new Router(getContext());
  router.attach("/v1/path", SomeServerResource.class);
  .
  router.attach("/v1/otherpath", SomeOtherServerResource.class);
  GaeAuthenticator guard = new GaeAuthenticator(getContext());
  router.attach(VERSION_PATH, guard);
  guard.setNext(router); 
  return guard;
...

I am assuming that what I want is not easily done (that is fine), but I
wanted to make sure before moving on (to trying to do hard things or just
not doing it).  

Thanks in advance!
RB
