使用Facebook4j API登录Facebook？

Question

I am using Facebook4j for interaction with facebook through my Java web application . i want to know What Data I have to save Into database So Next time When user come to my application no need to further

        String code = request.getParameter(OAUTH_CODE);
        if (code != null && code.length() > 0) {

            LOGGER.debug("We have a oauth code: {}.", code);
            LOGGER.debug("Attempting to verify the code...");

            Verifier verifier = new Verifier(code);

            LOGGER.debug("Trading the Request Token for an Access Token...");

            Token accessToken = service.getAccessToken(EMPTY_TOKEN, verifier);

            Token accessToken1 = new Token(token, apiSecret);

And now save these accessToken1 into database but everytime when i login from diffrent account i am getting same AccessToken ..What i am doing wrong? or what information i have to save into database

Answer 1

Where is your OAUTH_CODE coming from? If that is the same each time then your token will be the same too. How about the variable "token"? Is that your FB APP ID? So AccessToken1 is the APP token and accessToken is the user token?

Answer 2

The idea behind OAUTH is, that a user authorizes an app to do things in his/her name for a short amount of time. After is amount of time has passed the user has to authorize that app again. So there is nothing you can save that will help, your app will always need user interaction ;)
