Question

这是我将URl重定向到facebook

String uri = "";
    FacebookConnectionFactory connectionFactory = new FacebookConnectionFactory(MCRUtil.getMcrResourceBundle().getString("facebook.clientId"), MCRUtil.getMcrResourceBundle()
          .getString("facebook.clientSecret"));
    OAuth2Operations oauthOperations = connectionFactory.getOAuthOperations();
    OAuth2Parameters params = new OAuth2Parameters();

    String param = request.getParameter("param");
    if (param.equalsIgnoreCase("signUp")) {
        uri = redirectUri + "fbSignUp.htm";
    } else if (param.equalsIgnoreCase("friend")) {
        uri = redirectUri + "m-auth-fbfriends.htm";
    }
    params.setRedirectUri(uri);
    params.setScope("email,user_about_me,user_birthday,user_likes,user_status,publish_stream,friends_about_me,publish_actions,read_friendlists");
    params.setScope("email");
    params.set("display", "popup");
    String authorizeUrl = oauthOperations.buildAuthorizeUrl(GrantType.AUTHORIZATION_CODE, params);
    return "redirect:" + authorizeUrl;

我正在使用facebookconnectionfactory

此代码将重定向到facebook登录，然后我想将用户详细信息存储在我的数据库中。所以重定向另一个服务在下面

String facebookAccessToken = request.getParameter("code");
    if (facebookAccessToken == null) {
        return "socialError";
    }
    UserVO customer = null;
    AccessGrant accessGrant = null;
    /* By using clientId and secret getting connection facotiry */
    FacebookConnectionFactory connectionFactory = new FacebookConnectionFactory(MCRUtil.getMcrResourceBundle().getString("facebook.clientId"), MCRUtil.getMcrResourceBundle()
          .getString("facebook.clientSecret"));
    String uri = redirectUri + "fbSignUp.htm";

    OAuth2Operations oauthOperations=connectionFactory.getOAuthOperations();        

    accessGrant = oauthOperations.exchangeForAccess(facebookAccessToken, uri,null);
    Connection<Facebook> connection = connectionFactory.createConnection(accessGrant);
    Facebook facebook = connection.getApi();
    FacebookProfile userProfile = facebook.userOperations().getUserProfile();
    UserVO userVO = new UserVO();
    userVO.setEmail(userProfile.getEmail());
    userVO.setFirstName(userProfile.getFirstName());
    userVO.setLastName(userProfile.getLastName());

这里我得到accessGrant null数据.. accessGrant = oauthOperations.exchangeForAccess（facebookAccessToken，uri，null）; ..我正在使用spring-social-core-1.1.0 jar你可以帮助我如何获得accessGrant值......
