Using with twitter

[Luís Azevedo]

I'm having issues invoking twitter REST API using Google Oatuh Java Client. I'm able to do the first steps correctly:

1. Set the authorization url
2. Get the temporary token
3. Generate the final token

Then the Oatuh javadoc says:

Use the stored access token to authorize HTTP requests to protected resources by setting the OAuthParameters.token and using OAuthParameters as the HttpRequestInitializer.

It's in this step that I have issues. First of all if I only set the OAuthParameters.token value I'll get a null exception because the signer isn't set so what I presently have is:

OAuthParameters params = new OAuthParameters();
params.token=token;
params.version="1.0";
params.consumerKey=TWITTER_CONSUMER_KEY;
params.signer=signer;
HttpRequestFactory requestFactory = HTTP_TRANSPORT.createRequestFactory(params);
HttpResponse twResponse = requestFactory.buildGetRequest(new GenericUrl("https://api.twitter.com/1.1/account/verify_credentials.json")).execute();

The result is always:

WARNING: Authentication error: Unable to respond to any of these challenges: {} com.google.api.client.http.HttpResponseException: 401 OK {"errors":[{"message":"Could not authenticate you","code":32}]}

If I try the Authorization header given by twitter Oauth tool through a REST chrome extension tool it works perfectly so it's not an account issue. When I change it for the Authorization header value computed by the Google Oauth Java client library it doesn't work.

I don't get what I'm doing wrong.
