GoogleWebAuthorizationBroker在C#中抛出异常

Question

我正试图在Windows 8应用程序中使用OAuth与谷歌进行身份验证。在本教程之后，我将使用Google.NETClientneneneba API进行此操作。然而，当我使用GoogleWebAuthorizationBroker类时，我总是遇到一个异常。

我的代码是从链接的教程中复制/粘贴的。client_secrets.json包含我从Google API控制台下载的文件。我确实检查了它是否被复制到已安装的应用程序中，并且我可以打开它。日历API已打开。

UserCredential credidential = null;    
credidential = await GoogleWebAuthorizationBroker.AuthorizeAsync(
new Uri("ms-appx:///Assets/client_secrets.json"),
new[] { Uri.EscapeUriString(CalendarService.Scope.Calendar) },
"user", CancellationToken.None);

在try/catch中围绕这条线告诉我它失败是因为：
