Facebook GRAPH API的GET请求中缺少结果字段 [英] Missing result field in GET requests of the Facebook GRAPH API

问题描述

我正在尝试访问给定网址在Facebook上收到的喜好，分享和评论数量。

I'm trying to access the number of likes, shares and comments a given URL has received on facebook.

据了解这件作品的文档，以下网址应该给我我想要的。

As I understand this piece of doc, the following URL should give me what I want.

https://graph.facebook.com/v2.4?id=http://stackoverflow.com&fields=og_object,share&access_token=MY_ACCESS_TOKEN

它给了我以下内容：

{
"og_object": {
   "id": "10150180465825637",
   "description": "Q&A for professional and enthusiast programmers",
   "title": "Stack Overflow",
   "type": "website",
   "updated_time": "2015-08-02T04:03:47+0000",
   "url": "http://stackoverflow.com/"
},
"share": {
   "comment_count": 4,
   "share_count": 32567
},
"id": "http://stackoverflow.com"
}

其中包括comment_count = 4和share_count = 32567.

which includes comment_count = 4 and share_count = 32567.

但是，如果我参考以前链接的文档，喜欢的人数应该出现在og_object：应该有一个参与线，里面有两个元素， count （喜欢的数量）和 social_sentence （一个社会语句，如你和31,608,561其他这样的人。）

But, if I refer to the previously linked piece of doc, the number of likes should appear in "og_object" : there should be an engagement line with two elements inside, count (the number of likes) and social_sentence (a social sentence such as "You and 31,608,561 others like this.")

显然，这些参与和计数元素不存在。如何让他们出现？

Obviously, these engagement and count elements are not there. How can I have them appear ?

注意：在第一个URL ，我尝试更改& fields = og_object，share 部分：

NB : in the first URL, I tried changing the &fields=og_object,share part for any of these :

&fields=og_object.engagement,share
&fields=og_object.engagement.count,share
&fields=og_object,engagement,share
&fields=og_object,engagement,share
&fields=engagement,share
&fields=engagement.count,share
&fields=engagement,count,share
&fields=count,share

(NB : I also tried by putting `share` first in the list)

但没有一个工作，我总是收到一个这样的错误（每次尝试包括一个。）：

but none of them worked, I always get an error such as this one (every try which include a .) :

{
   "error": {
      "message": "Syntax error \"Expected \"(\" instead of \",\".\" at character 20: og_object.engagement,share",
      "type": "OAuthException",
      "code": 2500
   }
}

或这一个（每次尝试没有code>。

or this one (every try without a . :

{
   "error": {
      "message": "(#100) Tried accessing nonexisting field (engagement) on node type (URL)",
      "type": "OAuthException",
      "code": 100
   }
}

推荐答案

感谢@WizKid，答案是

Thanks to @WizKid, the answer is

https://graph.facebook.com/v2.4?id=http://stackoverflow.com&fields=og_object{engagement},share&access_token=

或

https://graph.facebook.com/v2.4?id=http://stackoverflow.com&fields=og_object{engagement{count}},share&access_token=

但是， og_object {engagement {count}} 和 share_count 显示相同的号码...等于 total_count 旧（&不推荐）

However, og_object{engagement{count}} and share_count display the same number... which is equal to the total_count when using the good old (& deprecated)

http://api.facebook.com/restserver.php?method=links.getStats&format=json&urls=h‌​ttp://stackoverflow.com/

似乎没有办法得到喜欢的数量和图表的数量api ...

It seems there is no way to get the number of likes and the number of shares with the graph api...
