如何使用fb api计算估计的每日覆盖率

Question

我想使用fb api显示每日估算的覆盖率。

我试过下面的代码： -

$ch = curl_init();
   curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
   curl_setopt($ch, CURLOPT_TIMEOUT, 60);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
   curl_setopt($ch, CURLOPT_USERAGENT, 'facebook');

$url_en = urlencode("{'geo_locations':{'countries': ['US'],},'age_min':20,'age_max':24}");


   curl_setopt($ch, CURLOPT_URL, "https://graph.facebook.com/v2.2/act_1375199556085956/reachestimate?access_token=ACCESS TOKEN&targeting_spec=".$url_en);

   curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
   curl_setopt($ch, CURLOPT_SSL_VERIFYHOST,  2);
   curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
   curl_setopt($ch, CURLOPT_HEADER, 0);
   //curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

   $data = curl_exec($ch);

但是得到以下的回复数据： -

"data": {
      "users": 14600000,
      "bid_estimations": [
         {
            "unsupported": false,
            "location": 3,
            "cpa_min": 79,
            "cpa_median": 145,
            "cpa_max": 195,
            "cpc_min": 45,
            "cpc_median": 70,
            "cpc_max": 87,
            "cpm_min": 8,
            "cpm_median": 20,
            "cpm_max": 27
         }
      ],
      "estimate_ready": true
   }
}

但是，我希望结果如下：

请帮助我。

在v2.9中添加

/<AD_ACCOUNT>/delivery_estimate

或

/<AD_SET>/delivery_estimate

参考：https://developers.facebook.com/docs/marketing-api/buying-api/targeting/v2.9
