java - Facebook4j - 用户属性 null

Question

我正在尝试使用 Facebook4j 执行用户搜索，但用户对象的所有属性都设置为 null(ID 除外)。

到目前为止的代码:

import facebook4j.Facebook;
import facebook4j.FacebookException;
import facebook4j.FacebookFactory;
import facebook4j.ResponseList;
import facebook4j.User;
import facebook4j.auth.AccessToken;
import facebook4j.conf.ConfigurationBuilder;

public class FacebookClient {

    public static void main(String[] args) throws FacebookException {

        ConfigurationBuilder cb = new ConfigurationBuilder();           
        cb.setOAuthAppId("...")
                .setOAuthAppSecret("...")

                /*A user access token with the following scopes: public_profile, basic_info,                      email, user_birthday, user_religion_politics, user_relationships, user_relationship_details, user_hometown, user_location, user_likes, user_activities, user_interests, user_education_history, user_work_history, user_website, user_groups, user_events, user_photos, user_videos, user_friends, user_about_me, user_status, user_games_activity, user_tagged_places, user_actions.music, user_actions.video, user_actions.news, user_actions.books*/
                .setOAuthAccessToken("");

        FacebookFactory ff = new FacebookFactory(cb.build());
        Facebook facebook = ff.getInstance();

        ResponseList<User> results = facebook.searchUsers("John Smith");

        for (User user : results) {
            System.out.println(user.getFirstName() + " " + user.getLastName());
            System.out.println(user.getBirthday());
            System.out.println(user.getId());
            System.out.println(user.getRelationshipStatus());
        }

    }

}

每个 User 对象的结果如下所示:

null null
null
111111111111111 //A different ID per object 
null

是否需要调整权限配置才能检索其他用户信息？

谢谢

尝试执行 out.println(facebook.toString()) 来查看是否有有效的实例。这可能是因为您正在从静态 main 中尝试此操作。
