I still don't understand how it work....GWT has 1 "main page". how can you restrict access to that page? If i go to myapp.appspot.com, the authentication servlet is not called. /Home.html * If I do this /* * then I get a redirect infinite loop problem when accessing myapp.appspot.com....

@Jesse: Well, as I wrote, I used the Cactus testing framework for it.. Since Cactus creates both client and server sides during the test, and then re-routes the requests and responses through the testing framework, it was a bit tricky to set up – but I guess it wasn’t a special case for OpenID but a case about how to use Cactus properly. Did you check that framework?

Did you ever write that post on how you unit tested OpenID?

There is a question on Stack Overflow trying to figure out how to test it from PHP/Zend, but I feel like your tests might be useful in understanding how to implement it in PHP.

Here’s where the question is: http://stackoverflow.com/questions/5258954/how-do-i-test-login-using-openid-in-zend-framework

Ok sorry, it was very easy :

// Attribute Exchange example: fetching the ‘email’ attribute
FetchRequest fetch = FetchRequest.createFetchRequest();
fetch.addAttribute(“email”, “http://schema.openid.net/contact/email”,true);
// obtain a AuthRequest message to be sent to the OpenID provider
AuthRequest authReq = this.manager.authenticate(discovered, this.callback.getOpenIdServletURL(), null);
authReq.addExtension(fetch);

Thank you

Thank you very much for this article,
I used it in a sample projet, and it worked.
Now I just don’t get how you retrieve the informations for the authenticated user you present in the response popup widget.
I read carfully the code, and parsed the http response but I can find the email for example or the full name.
Do I have to add parameters tu the request ?

There is a much simpler way to use OpenID on Google AppEngine.
Just use the following API:

UserService userService = UserServiceFactory.getUserService();

to get the authenticated user:

User user = userService.getCurrentUser();

to get the logout redirect URL:

String redirectURL = userService.createLogoutURL(destinationURL, authDomain);

to get the login redirect URL:

String redirectURL = userService.createLoginURL(destinationURL, authDomain, federatedIdentity, attributesRequest);

I have successfully used the following request attributes:

Set attributesRequest = new HashSet();
attributesRequest.add(“openid.mode=checkid_immediate”);
attributesRequest.add(“openid.ns=http://specs.openid.net/auth/2.0″);
attributesRequest.add(“openid.return_to=http://super-easy.appspot.com”);

A working example with the GWT widget to select an OpenID provider is
running under the http://super-easy.appspot.com

Hello Aviad,

I tried to implement your solution, but I am confused: Where do you get the HttpServletReqeust and Response from? I saw that they are required as parameters in OpenID but I was not able to determine where these variables should come from in GWT.
Thanks for your reply !

Best regards
