G’day everybody!

I’ve got error like this:

WARN/DefaultRequestDirector(22739): Authentication error: Unable to respond to any of
these challenges: {authsub=WWW-Authenticate: AuthSub
realm="https://www.google.com/accounts/AuthSubRequest" allowed-
scopes="https://www.googleapis.com/auth/userinfo.email,
https://www.googleapis.com/auth/userinfo.profile,
https://www.googleapis.com/auth/userinfo.id"}

It’s happend when I wanna get connection:

AccessGrant accessGrant = new AccessGrant(accessToken);
Connection<Google> connection = connectionFactory.createConnection(accessGrant);

As the result, I catch exception as Auth 401.

Did any one that problem befor?

    I’ve found why it was happened. The problem was in scope. I set only https://www.googleapis.com/auth/plus.me scope. It wasn’t enough for create connection.

    As result, I had the next message:

    WARN/DefaultRequestDirector(22739): Authentication error: Unable to respond to any of
these challenges: {authsub=WWW-Authenticate: AuthSub
realm="https://www.google.com/accounts/AuthSubRequest" allowed-
scopes="https://www.googleapis.com/auth/userinfo.email,
https://www.googleapis.com/auth/userinfo.profile,
https://www.googleapis.com/auth/userinfo.id"}

    As you can see google oauth2 asks for https://www.googleapis.com/auth/userinfo.email, https://www.googleapis.com/auth/userinfo.profile, https://www.googleapis.com/auth/userinfo.id scopes.

    After I had added this scopes and I got a new error likes “invalid_scope”.

    Problem was in connection url.

    I created connection url as:

    connectionFactory.getOAuthOperations().buildAuthorizeUrl(GrantType.AUTHORIZATION_CODE, params);

    where params:

    OAuth2Parameters params = new OAuth2Parameters();
params.setRedirectUri(redirectUri);
params.setScope("https://www.googleapis.com/auth/userinfo.email+" + "https://www.googleapis.com/auth/userinfo.profile+" + "https://www.googleapis.com/auth/userinfo.id+" + 
"https://www.googleapis.com/auth/plus.me");

    In this case, symbol “+” was decoded to another one and Google oauth2 api couldn’t recognize scope set.

    I hope this solution will help somebody in future.
