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

Answer 1

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 :)
