Question

我在导出广告统计报告时出现问题，因为我在使用ads_insights（版本2.5）时使用.NET Framework编写的代码。在我使用带有版本2.3的reportstats之前，我可以成功下载报告< / p>

我的请求是 // www.facebook.com/ads/ads_insights/export_report?report_run_id=0000000&format=xls&access_token=token

当我在浏览器中执行请求时，我可以成功下载报告（文件xls已完成），但是当我通过代码.NET Framework（C＃）执行请求时，我下载了.xls不完整的文件[在此处输入图像描述] [2]

获取报告的任务是（使用代码.NET C＃）

使用方法POST

1º请求

  Result: successful ->  I get a  report_run_id

使用GET方法请求2º

graph.facebook.com/v2.5/id_report&access_token=token

  Result: successful ->  I get a  
    {
      "id": "xxxx",
      "account_id": "xxx",
      "time_ref": 1447171267,
      "time_completed": 1447171269,
      "async_status": "Job Completed",
      "async_percent_completion": 100,
    }

当“async_status”为“作业完成”时，

3º，我执行请求

www.facebook.com/ads/ads_insights/export_report?report_run_id=xxxx&format=xls&access_token=token

结果：我下载的文件.xls不完整。如果您在浏览器中粘贴查询（URL），则下载报告成功（文件xls已完成）enter image description here

如果我使用代码.NET Framework（C＃）执行请求并将响应保存为字符串，则响应表明我们“应该更新您的浏览器”enter image description here

为什么我不能下载报告？

谢谢

Answer 1

我遇到了同样的问题，尝试使用npm请求下载报告的NodeJS。添加User-Agent标头解决了我的问题。

Answer 2

这对我有用。您的URL字符串中存在一些问题。这是一个更新的url字符串：

    string url = "https://www.facebook.com/ads/ads_insights/export_report?report_run_id=" + report_id + "&format=csv&access_token=" + accessToken;

此方法有效。

    using (WebClient wc = new WebClient())
    {
        wc.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
        wc.Headers["User-Agent"] = "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)";
        wc.DownloadFile(url, "page1.csv");
    }

报告将保存到：
