为什么私人群组的 "Sell Something" 个帖子不包含消息字段?

Why do "Sell Something" posts from a private group not contain a message field?

我在私人 FB 群组中从 Facebook Graph API(所有支持的版本)获得的结果与我访问实际 Facebook 网站时看到的结果不同。 "Sell Something" post 来自私人群组 /feed 的内容由于某种原因不包含 "message" 属性 等信息,尽管我可以在网站上看到它。

来自Facebook.com:

Christine : Can't go anymore! Selling last minute Front Orchestra tickets to the ...

Ingrid : For Sale: Portable booster seat high chair — Pick up at ...

来自图表 API:

[{
      ...
      "message": "Can't go anymore! Selling last minute Front Orchestra tickets to the ...", 

     "privacy": {
        "value": "", 
        "description": "", 
        "friends": "", 
        "allow": "", 
        "deny": ""
      }, 
      "type": "status", 
      "created_time": "2015-04-19T00:07:11+0000", 
      "updated_time": "2015-04-19T04:44:49+0000", 
      "is_hidden": false, 
      ...

    }, 
    {
      "privacy": {
        "value": "", 
        "description": "", 
        "friends": "", 
        "allow": "", 
        "deny": ""
      }, 
      "type": "status", 
      "created_time": "2015-04-16T22:11:36+0000", 
      "updated_time": "2015-04-19T04:41:01+0000", 
      "is_hidden": false, 
      ...
    }]

您会注意到在第一个 post 中只有一个 "message" 字段,而在第二个中没有 - 虽然,我看不出有任何理由会发生这种情况。

fields 路径参数中添加 attachments 属性。 URL 将如下所示:

/{group-id}/feed?fields=attachments

然后你将在每个适用的 [=26] 的 attachments 数组中有一个 group_sell_product_item 类型的对象=] 对象。你也可以有post的照片。

我仍然想知道如何获取价格信息...
