blocks|key|1257218|text|我在这个问题上做了很多调查。据我所知，没有办法使用Graph+API来做Friends.getAppUsers。Facebook提供的最新SDK都使用旧的REST+API来获得使用该应用程序的朋友。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1257219|entityMap^0|10|J|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I've done a lot of investigations on this issue. From what I can tell, there is no way to do <code>Friends.getAppUsers</code> using Graph API. The latest SDKs provided by Facebook all use the old REST API to get friends using the application.

blocks|key|1257347|text|这可以使用FQL来完成。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1257348|SELECT+uid+FROM+user

This can be done with FQL.

<pre><code>SELECT uid FROM user
WHERE uid IN (SELECT uid2 FROM friend WHERE uid1 = ?)
AND is_app_user = 1
</code></pre>

QED!

blocks|key|1257537|text|使用restFB，我做了以下事情(感谢Igy+/+Alex的指导)。请注意，如果用户已安装，Facebook将返回一个带有"+installed+"=true的好友if数组(如here所示)。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1257538|首先扩展User类，添加一个installed字段：|style|CODE|1257539|import+com.restfb.Facebook;

Using <a href="http://restfb.com/#" rel="nofollow">restFB</a>, I did the following (thanks Igy / Alex for the guidance). Note that Facebook returns an array of friend IDs with "installed"=true if the user is installed (as can be seen <a href="http://facebook.stackoverflow.com/questions/7956639/getappusers-using-c-sharp-opengraph-sdk/7957310#7957310">here</a>).

First extend the User class, adding an <code>installed</code> field:

<pre><code>import com.restfb.Facebook;
import com.restfb.types.User;

public class InstalledUser extends User {

 @Facebook
 private boolean installed;

 public InstalledUser() { 
 }

 public boolean getInsatlled() {
 return installed;
 }
}
</code></pre>

Next, using the DefaultFacebookClient:

<pre><code>FacebookClient facebook = new DefaultFacebookClient(pFacebookAccessToken);
Connection&lt;InstalledUser&gt; installedFacebookUsers = facebook.fetchConnection("/" + pFacebookId + "/friends", InstalledUser.class, Parameter.with("fields", "installed")); 
for (List&lt;InstalledUser&gt; friends : installedFacebookUsers) {
 for (InstalledUser friend : friends) {
 if (friend.getInsatlled()) {
 // Add friend.getId() to a list of ID, or whatever
 }
 }
}
</code></pre>

blocks|key|1042306|text|解决方法是自己进行过滤。大概，在您自己的数据库中有注册了您的应用程序的所有用户的uid。因此，首先获取所有用户的朋友的uids，然后从数据库中选择具有匹配uids的用户。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1042307|新的Facebook+Graph+API程序似乎执行得很差，也没有经过深思熟虑。在它成熟之前，他们似乎急于为Facebook+f8发布它，并且之前的许多功能都缺失了。|offset|length|1042308|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Facebook_f8^0|0|1I|B|0|0^^$0|@$1|2|3|4|5|6|7|N|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|O|8|@]|9|@$D|P|E|Q|1|R]]|A|$]]|$1|F|3|-4|5|6|7|S|8|@]|9|@]|A|$]]]|G|$H|$5|I|J|K|A|$L|M]]]]

The workaround is to do the filtering yourself. Presumably, you have all the uid's of the users who have signed up for your application sitting in your own database. So first get all the users' friends' uids, and select the users from your database who have matching uids.

The new Facebook Graph API program seems very poorly executed and not quite thought through. It seems they rushed to publish it for <a href="http://en.wikipedia.org/wiki/Facebook_f8" rel="nofollow noreferrer">Facebook f8</a> before it was mature, and lots of functionality is missing that was available before.

blocks|key|1042455|text|您仍然可以在新的Graph+API中调用旧的REST+API。这是非常有效的。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1042456|另一种方法是使用FQL来获得应用程序用户的好友。|1042457|我不确定是否有只使用Graph+API就能做到这一点的方法。|1042458|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|H|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|I|8|@]|9|@]|A|$]]|$1|D|3|E|5|6|7|J|8|@]|9|@]|A|$]]|$1|F|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|G|$]]

You can still call the old REST API's in the new Graph API. That is prefectly valid.

An alternative way is to use FQL to get the application user's friends. 

I'm not sure if there's a way to do this using just Graph API.

I have an application that uses the old REST API call <code>Friends.getAppUsers</code> to get the list of friends for the current user that have authorized my application.

I have read the documentation, how do I do this with the Graph API? What would an example of this be?

Facebook 'Friends.getAppUsers' using Graph API

数据库

我有一个应用程序，它使用旧的REST API调用Friends.getAppUsers来获取授权我的应用程序的当前用户的朋友列表。我已经阅读了文档，我该如何使用Graph API来实现这一点？这方面的例子是什么？
