从Page Post Likes'summary'获取'total_count' - Facebook PHP SDK(已关闭)

Question

我是PHP和Facebook PHP SDK的新手,我希望'like_count'从'likes' 'summary'Facebook页面帖子中获取.我当前的代码包含以下内容:

$response = $fb->get('/me/posts?fields=admin_creator,likes.limit(0).summary(true)&limit=30');
$getLikeCount = $response->getGraphEdge()->asArray();
foreach($getLikeCount as $likekey){
    if(isset($likekey['likes'])){
        var_export($likekey['likes']);
        foreach ($likekey['likes'] as $likekey){
            //echo $likekey['total_count'] . '<br>';
        }
    }
}

该var_export($likekey['likes']);出口空白阵列,同时var_export($likekey['summary']);返回null.但是,在Graph API Explorer中,它返回以下内容:

{
      "admin_creator": {
        "name": "NAME",
        "id": "ID"
      },
      "id": "ID",
      "likes": {
        "data": [
        ],
        "summary": {
          "total_count": 1022,
          "can_like": true,
          "has_liked": false
        }
      }
    },

我如何访问该'total_count'字段,因为通过我的方法访问它'likes'并且" summary'不工作".

编辑:使用getGraphEdge()->asArray();将无法工作,因为它不返回摘要数组.我会以某种方式获取值getDecodedBody();或其他方法.如果我使用$getLikeCount = $response->getDecodedBody();,使用此代码:

foreach($getLikeCount as $key){
    if(isset($key['admin_creator'])){
        echo $key['admin_creator']['name'];
    }
}

它没有返回任何东西.我正在使用它'admin_creator'作为一个例子,因为它$getLikeCount = $response->getGraphEdge()->asArray();在我当前的方法中起作用,但是我不能使用这种方法,因为我试图'total_count'从'summary'post中获取字段,'likes'并且'summary'在使用getGraphEdge()方法时不会在数组中显示仅在使用时显示getDecodedBody();.我想知道是否有办法从中获取值,getDecodedBody()或者是否有解决方法来获取该total_count字段summary.

答案: 答案可以在下面找到.

您可以在不进行更多API调用的情况下找到此数据.摘要数据被隐藏在该领域的元数据的喜欢.评论和反应也是如此.

$response = $fb->get('/me/posts?fields=id,likes.limit(0).summary(true)');
foreach ($reponse->getGraphEdge() as $graphNode) {
    // Some fields can have metadata
    $likesData =  $graphNode->getField('likes')->getMetaData();
    echo 'The total of likes for the post ID "' .  $graphNode->getField('id') . '" is: '. $likesData['summary']['total_count'];
}
