OAuthProblem, missing parameter access_token

Question

I'm getting this error while trying to get an access token for a user. This has to do with the authorization process of a facebook application. The code that produces that exception is the following:

OAuthClientRequest oAuthRequest = OAuthClientRequest
    .tokenLocation("https://graph.facebook.com/oauth/access_token")
    .setGrantType(GrantType.AUTHORIZATION_CODE)
    .setClientId("myAppId")
    .setClientSecret("myAppSecret")
    .setRedirectURI("myAppURL").setCode(code)
    .buildBodyMessage();

And the exception thrown follows beneath:

12:14:22,468 ERROR [STDERR] OAuthProblemException{description='Missing parameters:   
access_token', error='invalid_request', uri='null', state='null', scope='null'}

Answer 1

I think you can use the normal OAuthJSONAccessTokenResponse:

OAuthAccessTokenResponse oAuthResponse = oAuthClient.accessToken(request);

my problem is, Facebook responds with

OAuthProblemException{description='null', error='{"message":"Error validating verification code.","type":"OAuthException","code":100}', uri='null', state='null', scope='null'}

Any ideas?

Answer 2

I had the same problem implementing the client and the server, the problem is about one mistake in the Client Example in the Apache Amber (Oltu) project:

First you have the Auth code request (which work):

OAuthClientRequest request = OAuthClientRequest
 .authorizationLocation(AUTHORIZE_URL)
 .setClientId(CLIENT_ID)
 .setRedirectURI(REDIR_URL)
 .setResponseType(CODE_RESPONSE)
 .**buildQueryMessage**();

And second the request about the Access Token (which don't work):

OAuthClientRequest request = OAuthClientRequest
  .tokenLocation(ACCESS_TOKEN_URL)
  .setGrantType(GrantType.AUTHORIZATION_CODE)
  .setClientId(CLIENT_ID)
  .setClientSecret(CLIENT_SECRET)
  .setRedirectURI(REDIR_URL)
  .setCode(code)
  .**buildBodyMessage**();

The mistake is about the buildBodyMessage() in the second request. Change it by buildQueryMessage().

Enjoy :)
