Question

我需要你的帮助。

我正在使用restfb库开发一个java应用程序，我希望在fb上获得所有喜欢我的粉丝页面的facebook用户。我工作了很多天才做到这一点，但我找不到解决方案。

我写了这段代码，但它只返回了likers的数量：

FacebookClient fb= new DefaultFacebookClient("ACCESS_TOKEN");
        Page page = fb.fetchObject("PAGE_ID", Page.class);
        System.out.println("My pages likes: " + page.getLikes());

请注意，当我登录fb页面时，我从Graph API资源管理器获取ACCESS_TOKEN，因为我没有找到从java代码获取令牌的方法。所以当我退出海时出现这个错误：

Exception in thread "main" com.restfb.exception.FacebookOAuthException: Received Facebook error response of type OAuthException: Error validating access token: The session is invalid because the user logged out.
    at com.restfb.DefaultFacebookClient$DefaultGraphFacebookExceptionMapper.exceptionForTypeAndMessage(DefaultFacebookClient.java:766)
    at com.restfb.DefaultFacebookClient.throwFacebookResponseStatusExceptionIfNecessary(DefaultFacebookClient.java:688)
    at com.restfb.DefaultFacebookClient.makeRequestAndProcessResponse(DefaultFacebookClient.java:630)
    at com.restfb.DefaultFacebookClient.makeRequest(DefaultFacebookClient.java:592)
    at com.restfb.DefaultFacebookClient.makeRequest(DefaultFacebookClient.java:556)
    at com.restfb.DefaultFacebookClient.fetchObject(DefaultFacebookClient.java:244)
    at testrestfb.testfb.main(testfb.java:95)

请帮我解决这个问题..

提前致谢。

您应该使用fql查询获取有关此类信息的信息。

请参阅下面的“拨打更复杂的电话”

这里我们让API调用fql.query来执行自定义查询。

// FQL query which asks Facebook for your friends' names,
// profile picture URLs, and network affiliations

String query =
  "SELECT name, pic_big, affiliations FROM user " +
  "WHERE uid IN (SELECT uid2 FROM friend WHERE uid1=12345)";

// Executes an API call with result mapped to a list of classes we've defined.
// Note that you can pass in an arbitrary number of Parameters - here we
// send along the query as well as the "give me HTTPS URLs" flag

List<User> users =
  facebookClient.executeForList("fql.query", sessionKey, User.class,
    Parameter.with("query", query), Parameter.with("return_ssl_resources", "true"));
