我正在编写应用程序，它将在 facebook 中读取我朋友的状态更新。即使我拥有完整的权限列表，我也有这个“必须使用活动访问令牌来查询有关当前用户的信息”错误。我现在不知道该怎么办。谢谢！

我在 System.out.println(response); 上遇到的错误：
{"error":{"type":"OAuthException","message":"An active access token must be used to query information about the current user.","code":2500}}
固定：只需在参数中包含访问令牌：
String fqlQuery = "SELECT status_id, uid , message FROM status WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = me())";
Bundle params = new Bundle();
params.putString("q", fqlQuery);
params.putString("access_token", facebook.getAccessToken());
Session session = Session.getActiveSession();
Request request = new Request(session,
"/fql",
params,
HttpMethod.GET,
