【问题描述】：

我想检索可以在单个 Facebook 帖子中发布的所有照片。例如，在这个post 中，有两张照片。使用 Graph API (https://graph.facebook.com/v2.6/AtifAslamOfficialFanPage/posts?fields=id,type,created_time,link,message,source,object_id&limit=10&access_token=xxx) 我得到这篇文章：

{
     "id": "182973122142_10153437154822143",
     "type": "photo",
     "created_time": "2016-03-18T17:47:23+0000",
     "link": "https://www.facebook.com/AtifAslamOfficialFanPage/photos/a.281303247142.151444.182973122142/10153437154412143/?type=3",
     "object_id": "10153437154412143"
  }

但只有一个object_id，即帖子的第一张照片。

是否可以检索所有照片？

请求attachments字段，182973122142_10153437154822143?fields=attachments，会得到如下数据结构：

  "attachments": {
    "data": [
