Re: GWT Oauth Access Token Access Revoked

I solved my own problem.

Turns out there is a clearAllTokens() method from Auth.

Hi, I ran into an issue with using https://code.google.com/p/gwt-oauth2/source/browse/trunk/samples/multi/com/google/api/gwt/oauth2/samples/multi/client/OAuth2SampleEntryPoint.java

for a specific use case.

The login method, as described below, will not open a popup window if my token not close to expiring yet. So so if I revoked access to my application (from my Google Account > Security > Authorizing applications and sites), the login method does not open the popup window to prompt to to re-grant access, instead it just gives me back the existing token (since it has not expired yet). And now, when I try to use that token to make requests to Google API, these requests will fail because I revoked access, so the token is invalid.

Now, my question is, how do I make the login method from this client to force open the popup window to prompt user to grant access again?

public void login(AuthRequest req,                    Callback<String,Throwable> callback)

Request an access token from an OAuth 2.0 provider.

If it can be determined that the user has already granted access, and the token has not yet expired, and that the token will not expire soon, the existing token will be passed to the callback.

Otherwise, a popup window will be displayed which may prompt the user to grant access. If the user has already granted access the popup will immediately close and the token will be passed to the callback. If access hasn't been granted, the user will be prompted, and when they grant, the token will be passed to the callback.

Parameters:

req - Request for authentication.

callback - Callback to pass the token to when access has been granted.
