從Facebook的開放式圖表中獲取針對Facebook頁面的見解/ page_fans

我正在嘗試獲取音樂藝術家在其Facebook頁面上擁有的歌迷人數，但這不起作用。我已經梳理了FBAPI文檔以及SO，但仍然沒有。這裏是我的代碼：從Facebook的開放式圖表中獲取針對Facebook頁面的見解/ page_fans

func getHolychildInfo() { 
    //Make request 
    let newGraphRequest: FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "/holychildmusic/insights/page_fans", parameters: ["period" : "lifetime", "show_description_from_api_doc" : "true", "fields": "read_insights"], httpMethod: "GET") 
    newGraphRequest.start(completionHandler: { (connection, result, error) in 
     if ((error) != nil) { 
      print("Holychild error getting insights: \(error.debugDescription)") 
     } else { 
      print("\nHolychild insights result:\n\n\(result)") 
     } 
    }) 
}

這裏是我的結果：

data =  (
); 
paging =  { 
    next = "https://graph.facebook.com/v2.8/holychildmusic/insights/page_fans?access_token=EAAIB5k3aWEEBAHBD9lZC5AAzZAVV8K8CGBfqaxcrLdZA7oZB2Gdar8cQphXj4VciloZAnZBKp5ZA59BmGloSNz847nFqZCTVsYZCl9rrOk88OnfCnDwwADKnkOO5EUhGumEbW96riHplgfBLdnZAEYmB2Qz4ZAH1sWbuftmGKDqPft4l5QAHSZAimIyI6sOHaKWiurRK201Af6NQCXGliZBsZAUYosUHttkUbo4CQZD&fields=read_insights&format=json&include_headers=false&period=lifetime&sdk=ios&show_description_from_api_doc=true&since=1487457711&until=1487716911"; 
    previous = "https://graph.facebook.com/v2.8/holychildmusic/insights/page_fans?access_token=EAAIB5k3aWEEBAHBD9lZC5AAzZAVV8K8CGBfqaxcrLdZA7oZB2Gdar8cQphXj4VciloZAnZBKp5ZA59BmGloSNz847nFqZCTVsYZCl9rrOk88OnfCnDwwADKnkOO5EUhGumEbW96riHplgfBLdnZAEYmB2Qz4ZAH1sWbuftmGKDqPft4l5QAHSZAimIyI6sOHaKWiurRK201Af6NQCXGliZBsZAUYosUHttkUbo4CQZD&fields=read_insights&format=json&include_headers=false&period=lifetime&sdk=ios&show_description_from_api_doc=true&since=1486939311&until=1487198511"; 
};

正如你所看到的，沒有什麼迴應的「數據」部分。「page_fans」見解度量標準應該返回一個數字 - 除其他外 - 但不會返回任何內容。
