Facebook Graph API - 获取页面/群组照片的点赞数

Question

我一直在测试图形 API 并遇到问题。如何从页面/组的照片中获取点赞数？

我是群组的管理员/创建者。在 https://developers.facebook.com/tools/explorer/ 中输入特定照片 ID 时它带来了该组的几乎所有数据，甚至评论，但不包括点赞数。对于类似的部分，它需要（根据文档）访问令牌，尽管任何人都可以访问该信息。

如何获取具有所需权限的页面/组的访问令牌以及如何使用它来获取我需要的信息？

如果可能的话，我想从单个地址获取 JSON。

Answer 1

这可以通过页面实现（即使没有访问令牌！），具体方法如下：

访问图表上的页面

通过转到页面的 url 获取页面的 ID：

https://www.facebook.com/pages/platform/19292868552

网址末尾的数字是页面的 ID。获取该 ID 并将其与图形浏览器一起使用（此处）或直接访问它直接。

访问页面的相册

现在，将相册附加到该网址将为您提供该页面拥有的所有相册，包括墙上的照片：

https://graph.facebook.com/19292868552/albums

输出如下所示：

{
   "data": [
      {
         "id": "10150160810478553",
         "from": {
            "name": "Facebook Platform",
            "category": "Product/service",
            "id": "19292868552"
         },
         "name": "Bringing Operation Developer Love to Europe",
         "description": "Blog post: http://developers.facebook.com/blog/post/479\n\nVideos and presentations uploaded here: http://developers.facebook.com/videos/",
         "location": "Berlin, Paris, London",
         "link": "https://www.facebook.com/album.php?fbid=10150160810478553&id=19292868552&aid=285301",
         "cover_photo": "10150160811078553",
         "count": 32,
         "type": "normal",
         "created_time": "2011-04-06T23:05:44+0000",
         "updated_time": "2011-04-06T23:33:20+0000",
         "comments": {
         ..... etc ....

选择相册

对于data 数组有一个id 和一个name。使用这两个字段，您可以选择包含所需照片的相册。该结果中的第一张专辑是“Bringing Operations Developer Love to Europe”。我们来看看这张专辑的照片。

查看照片

如果您到目前为止已经按照答案进行操作，那么下一步应该相当明显。使用您想要的相册的 id 并将照片附加到图表网址：

https://graph.facebook.com/10150160810478553/photos

查看照片的喜欢

就像选择相册一样，只需使用id 在上述步骤的输出中，并将 likes 附加到网址以查看喜欢的照片：

https:// /graph.facebook.com/10150160813853553/likes

输出：

{
   "data": [
      {
         "id": "1163036945",
         "name": "Aditya Pn"
      },
      {
         "id": "1555885347",
         "name": "Nadin M\u00f6ller"
      },
      {
         "id": "100001643068103",
         "name": "Umut Ayg\u00fcn"
      },
      {
         "id": "100000165334510",
         "name": "Alessandra Milfont"
      },
      {
         "id": "100001472353494",
         "name": "Sayer Mohammad Naz"
      },
      {
         "id": "1051008973",
         "name": "Jenson Daniel Chambi"
      },
      {
         "id": "100000233515895",
         "name": "Ruby Atiga"
      },

使用此输出，您可以简单地计算数据数组中的条目数以获得点赞数。

请注意，所有这一切都可以通过使用图形浏览器通过单击输出框中的 id 和连接侧边栏（ 除了最后一个 /likes 连接，希望很快就会添加。此外，您不需要访问令牌即可执行任何操作，因为页面是公开的。

Answer 2

您可以通过结合使用 fields 参数和 likes.limit(1).summary(true) 来获取评论/喜欢计数，而无需对所有喜欢进行分页。例如，下面对披萨的搜索 api 查询将为您提供所有公共帖子及其汇总的点赞数：

https://graph.facebook.com/search?q=pizza&type=post&fields=id,name,likes.limit(1).summary(true)

结果（截断）：

{
  "data": [
    {
      "id": "47883936273_659693910762305",

            "id": "100002243084532", 
            "name": "Yvette Martin"
          }
        ], 
        "paging": {
          "cursors": {
            "after": "MTAwMDAyMjQzMDg0NTMy", 
            "before": "MTAwMDAyMjQzMDg0NTMy"
          }, 
          "next": "https://graph.facebook.com/47883936273_659693910762305/likes?limit=1&summary=1&after=MTAwMDAyMjQzMDg0NTMy"

        "summary": {
          "total_count": 2792
        }
      }
    }

Answer 3

/me/feed 返回一个 LIKES 字段

我使用了一个解决方案，我只需查找数组中显示 LIKES 的项目数

Object.keys(item.likes.data).length

。这将返回对象的“长度”——等于喜欢的数量。
