使用Graph API，如何檢索評論的圖像並回復評論？

Question

我正在創建一個Android應用程序。該應用程序具有使用Graph API檢索Facebook帖子的功能。

我的問題
我的問題是，收到的JSON缺少以下字段：

• 注釋所附圖片的網址
  
• 回復評論
• 只能提供喜歡的數量。 沒有反應清單
• 對於包含多個圖像的帖子， full_picture字段僅包含指向一個圖像的鏈接。 其他圖像的鏈接在哪里？

我使用了/me/posts來獲取帖子。

為什么我無法獲得上述詳細信息？

采取的步驟
我搜索了Stackoverflow，但答案僅提及如何獲取圖像和單個評論的答復（通過使用注釋id），但沒有提及如何將其與從"/me/posts"接收的JSON一起使用。 （所以，這不是重復的！！！！）

我的查詢

• 為什么我無法獲得上述詳細信息？
• 如何以捆綁的方式獲取父帖子和帖子反應的所有圖片的評論圖像，回復，URL。（即與"/me/posts"的JSON一起使用，而無需為每個/comment運行/comment請求的方式是什么？

好吧，關於“反應列表”，這僅適用於Page所有者（從2018年2月起）。
