Question oauth website


I met in the development of a little confused. I use twitter4j to obtain requestToken, also obtained the authorization url: Oauth_token = LxNxIovSrCN1VhV2fu02beZ9Wqh8Lmbz9WkzCRCE4go
Everything is going well.
But when the second time I request to this url, the same twitter account still can’t skip this page, to request authorization application again.
I want a second visit is no longer required authorization, could you tell me I should how to modify?
