Facebook Graph API Insights重视差异

Question

我正在使用Graph API从facebook上获取数据，但是我发现奇怪的是，根据选择的时间段，这些值对我而言没有意义。

要求

 /insights/page_impressions_unique?since=1432191600&until=1433401200

返回以下值：

  "name": "page_impressions_unique", 
      "period": "day", 
      "values": [
        {
          "value": 2, 
          "end_time": "2015-05-22T07:00:00+0000"
        }, 
        {
          "value": 8, 
          "end_time": "2015-05-23T07:00:00+0000"

        }, 
        {
          "value": 131, 
          "end_time": "2015-06-04T07:00:00+0000"
        }
      ], 

我知道“ period”：“ week”值是end_time之前7天的总和，但是我无法通过在“ period”：“ day”中加上天数来获得这些值。

TL; DR：有人知道如何通过添加日值来获取周值吗？

Answer 1

这是因为当您要求每周时，它会为您提供每周数据平均值，对于"end_time": "2015-05-22T07:00:00+0000"该数据是最近7天，即包含"2015-05-16T07:00:00+0000"数据"2015-05-16T07:00:00+0000"到"2015-05-22T07:00:00+0000"而对于"end_time": "2015-05-23T07:00:00+0000"该数据是最近7天的数据，即由"2015-05-17T07:00:00+0000" to "2015-05-23T07:00:00+0000" 。

如果您将这一日期范围内的一天中的所有值相加，则由于过去7天的唯一性，您可以获得的值大于或等于按周数据返回的值。

您也可以尝试

 /insights/page_impressions_unique?since=1432191600&until=1432364400

那么您将获得每周数据，但是由于是"2015-05-21T07:00:00+0000" & until is "2015-05-23T07:00:00+0000" ，日期范围是2天数据，但我们会得到每周的数据也是如此。

以上信息作为Facebook团队有效，我从Facebook开发人员那里得到了这个答案。 我们与Facebook团队就应用程序中存在的相同问题进行了交谈。
