带图片的 Facebook 评论

Question

有没有办法推断 Facebook 上的评论是否附加了 photo/image（使用图表 API）？例如，带有此 id 的评论：

10153245215739574_10153245218744574

有照片，但在查询此对象时，如果评论附有照片，似乎没有字段泄露：

{ "id": "10153245215739574_10153245218744574", "from": { "id": "1377902372514543", "name": "Alecsander Ferreira" }, "message": "QUEEN <3", "can_remove": false, "created_time": "2015-02-22T05:21:16+0000", "like_count": 2037, "user_likes": false }

Answer 1

在没有明确说明字段的情况下查询对象将仅提供默认字段。您需要请求您需要的字段。

例如

10153245215739574_10153245218744574?fields=attachment

{
  "attachment": {
    "type": "photo", 
    "title": "", 
    "target": {
      "id": "1407980226173424", 
      "url": "https://www.facebook.com/photo.php?fbid=1407980226173424&set=p.1407980226173424&type=1"
    }, 
    "url": "https://www.facebook.com/photo.php?fbid=1407980226173424&set=p.1407980226173424&type=1", 
    "media": {
      "image": {
        "height": 720, 
        "src": "https://scontent.xx.fbcdn.net/hphotos-xpf1/v/t1.0-9/s720x720/11021095_1407980226173424_823555107490491827_n.jpg?oh=96e50bb93269d6e69067a8b3ebf98292&oe=558E78CF", 
        "width": 531
      }
    }
  }, 
  "id": "10153245215739574_10153245218744574"
}
