FB Open Graph GET og.likes 请求中的 "likes" 字段是什么?

What is the "likes" field from an FB Open Graph GET og.likes request?

我已经在我正在开发的跨平台移动应用程序 (Phonegap) 中实现了点赞非 FB URL 的功能,部分功能是我需要了解用户是否之前喜欢过 URL,因此对 og.likes 对象进行了 GET。在这个请求的结果中,og.likes 数据中有一个我不确定的字段。

我的要求:

GET me/og.likes?access_token={AccessToken}&object={EncodedExternalURL}

回复:

{
  "data": [
    {
      "id": "_____", 
      "from": {
        "id": "______", 
        "name": "______"
      }, 
      "start_time": "2015-01-12T06:17:24+0000", 
      "end_time": "2015-01-12T06:17:24+0000", 
      "publish_time": "2015-01-12T06:17:24+0000", 
      "application": {
        "name": "______", 
        "namespace": "______", 
        "id": "______"
      }, 
      "data": {
        "object": {
          "id": "____", 
          "url": "____", 
          "type": "website", 
          "title": "____"
        }
      }, 
      "type": "og.likes", 
      "no_feed_story": false, 
      "likes": { // <-- this guy here and its properties
        "count": 0, 
        "can_like": true, 
        "user_likes": false
      }, 
      "comments": {
        "count": 0, 
        "can_comment": true, 
        "comment_order": "chronological"
      }
    }
  ], 
  "paging": {
    "next": "____"
  }
}

likes 字段是什么?还有countcan_likeuser_likes的子属性?是不是其他用户也能喜欢这个Like?

likes 字段用于管理该点赞拥有的点赞数。用户可以点赞或评论。
