【问题描述】：

是的，我有一个问题，我已经做了很多研究，但我仍然无法解决这个问题。我想要实现的是当 facebook 用户喜欢我的页面而不是应用程序时，我希望能够检索所有喜欢 facebook 页面的用户。

我正在使用 FQL，但完全没有运气，如果我根据页面管理员执行 FQL，它会显示数据。

SELECT first_name, last_name FROM user WHERE uid IN (SELECT uid FROM page_fan WHERE page_id = [your page id])

上面的 FQL 应该可以工作。但是什么都没有显示，这是一个没有被标记或修复的 facebook 错误吗？

【解决方案1】：

您可以向/USER_ID/likes/PAGE_ID 发出 GET 请求（将大写部分替换为相关 ID），以检查特定用户是否是您页面的粉丝。这是旧的“pages.isFan”API 方法的替代品。无法检索喜欢您的页面的用户列表。
