troubleshooting scribe for social api authentication

Question

I just started looking at scribe for authentication with social networks such as twitter/facebook etc. I am using the example for twitter as reference. However, I don't seem to get oauth_verifier from twitter for some reason (even though the callback is registered through the service builder - I am using localhost in the callback as it worked with another social api). Any helpful suggestions would be quite welcome. thanks in advance.

OAuthService service = new ServiceBuilder()
.provider(TwitterApi.class)
.apiKey(consumerKey)
.apiSecret(consumerSecret)
.callback("http://localhost/oauth/twitter")
.build();

        //get the token
        Token requestToken = service.getRequestToken();

        String authUrl = service.getAuthorizationUrl(requestToken);
        Logger.info("authurl::" + authUrl); // not getting the oauth_verifier

Debug output from scribe (I changed the token info):

Update: I am able to receive the oauth_verifier now. I will update this post once I am done testing.

Answer 1

pilot error mostly. I was able to get oauth working with twitter using scribe. After getting the service, the request Token from the service & then the authorizationUrl from the service (while passing in the request token), I was able to redirect to the authorization URL. Once there, I was able to authenticate myself against twitter using my twitter ID which redirected me to the callback URL specified when I created the service. Upon authentication, I received the oauth_verifier which I was able to use to create the verifier & then receive the access token from the service using the verifier and the request token. Then the oauth request was made & signed which resulted in the response from twitter with the user details. Worked. Hope it helps.
