在FB Graph API中确定具有ID的对象的类型 [英] Determining type of object with id in FB Graph API

问题描述

是否有一种方法可以确定给定ID https://graph.facebook.com/ID代表哪种对象.当我在Graph API Explorer工具中请求时，响应中有一个名为type的字段，该字段可能包含user，page，album，photo等.但是，当我从浏览器或通过SDK请求相同内容时，作为响应，没有这样的字段，但是其他所有内容都是相同的.而且我不得不猜测我依赖于其他字段的种类是什么:例如，如果有一个字段gender表示我有user对象.我认为这是FB Graph API中的错误.有什么解决办法吗?

Is there a way to determine what kind of object is represented by the given ID https://graph.facebook.com/ID. When I'm requesting this in Graph API Explorer tool, in the response there is a field named type, that could contain user, page, album, photo and so on. But when I'm requesting the same from browser or via SDK, in response there is no such field, but everything else is the same. And I have to guess what kind of object I have relying on other fields: for example if there is a field gender that means that I have user object. I think this is a bug in FB Graph API. Is there any solution for this?

推荐答案

如果您通过在请求中添加metadata参数来使用Facebook上称为自省"的东西，则可以这样做:

This is possible if you using something Facebook call "introspection" by adding metadata argument to your request:

GET http://graph.facebook.com/object_id?metadata=1

结果将包含type字段
