有时候，Facebook Graph API object_id丢失 [英] Facebook Graph API object_id missing sometimes

问题描述

我的请求网址是：
xxxxxxxxxxxxxx / feed？fields = from ，id，created_time，picture，link，object_id，message，likes.fields（id）

使用object_id，我想获得该帖子的大图，使用以下网址：
http://graph.facebook.com/OBJECT_ID/picture ？type = normal

图片返回字段始终被填充，但是在某些帖子中没有返回object_id。为什么是这样？我真的需要高分辨率的图片，没有找到另一种获取方式。

解决方案

仅返回object_id如果附件是Facebook对象（例如用户上传的图像）。 Feed中的一些故事根本没有图片，一些图片不是Facebook对象（例如，共享链接的缩略图）。

I am using the Facebook Graph API to get the news feed of a user.

My request URL is: xxxxxxxxxxxxxx/feed?fields=from,id,created_time,picture,link,object_id,message, likes.fields(id)

With the object_id, I want to get the big picture of the post, using the following url: http://graph.facebook.com/OBJECT_ID/picture?type=normal

The picture return field is always filled, but the object_id is not being returned at some posts. Why is this? I really need the high res picture, and didn't find another way to acquire this..

解决方案

The object_id is only returned if the attachment is a facebook object (e.g. an image uploaded by the user). Some stories in feed don't have a picture at all, and some pictures are not facebook objects (e.g. thumbnails for shared links).
