Question

对于大多数（如果不是所有）Facebook API调用的对象洞察，我得到一个空数据数组的响应。我在登录时请求以下权限：read_insights，publish_pages，manage_pages。

我要做的一些请求包括：page_views_total，page_impressions，page_fans

FB.api(
      "/1493689654199431/insights/page_impressions/lifetime",
      function (response) {
        if (response && !response.error) {
          console.log(response);
        }
      }
  );

回应示例：

{
  "data": [
  ],
  "paging": {
    "previous": "https://graph.facebook.com/v2.6/1493689654199431/insights/page_impressions/lifetime?access_token=EAACEdEose0cBAGNO4tT95osm9KIaLlsoxoWPyk7g4J6m3iBwa5ZArxGEZBbeIpILExuTZAC6KFRHfCuccbsOCCQLmRZCItZAAmTs3PXzueCCJ0CVjr6UBB3gZCfClQeeI1PbHZCnJVqZBPHf00Vl6U4Lj6B1FpMhZAqUSdXNvcPDWlAZDZD&debug=all&format=json&method=get&pretty=0&suppress_http_code=1&since=1462194002&until=1462453202",

}

Answer 1

JavaScript SDK默认使用用户令牌，您需要获取并使用Page Insights的Page令牌。你得到一个带有/me/accounts端点的页面令牌，这就是你如何使用它：

FB.api(
    "/1493689654199431/insights/page_impressions/lifetime",
    {access_token: pageToken},
    function (response) {
        if (response && !response.error) {
            console.log(response);
        }
    }
);

您可以在此处调试您的页面令牌：https://developers.facebook.com/tools/debug/accesstoken/

Answer 2

The reason being, page_impressions takes only three values for period = day, week, days_28.

I tried with

FB.api('/page-id/insights/page_impressions/days_28',{access_token: page-access-token}, function(response){
    console.log('page impressions',response);
})

and got data.

Had the same issue of empty data, it got resolved
