c# - 为什么我得到 System.UnauthorizedAccessException Access to the path 'Google.Apis.Auth' is denied

Question

我已经实现了用于文件管理的谷歌驱动器功能，它在本地系统中运行良好，但每当我将它托管在 Godaddy 服务器上时，它就会抛出以下错误

System.UnauthorizedAccessException Access to the path 'Google.Apis.Auth' is denied.

我正在使用以下代码:

UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
   new ClientSecrets
   {
       ClientId = System.Configuration.ConfigurationManager.AppSettings["GDriveClientId"],//Get ClientID from web.config.
       ClientSecret = System.Configuration.ConfigurationManager.AppSettings["GDriveClientSecret"]//Get ClientSecret from web.config.
   },
   new[] { DriveService.Scope.Drive },
   System.Configuration.ConfigurationManager.AppSettings["GDriveCreatedByUser"],//Get UserName from web.config.
   CancellationToken.None).Result;

return credential;

我正在使用 VS2010，IIS 7 来实现上述功能

扩展 Chandrika 已经说过的内容，ASP.NET 用户需要对 Google API 客户端 OAuth2 库的永久存储文件夹具有读写权限。

它的默认值是 Environment.SpecialFolder.ApplicationData 中名为“Google.Apis.Auth”的文件夹(通常对应于 C:\Users\your-user-name\AppData\漫游)。

或者，可以提供另一个文件夹作为 GoogleWebAuthorizationBroker.AuthorizeAsync() 的最后一个参数方法:

var folder = System.Web.HttpContext.Current.Server.MapPath("/App_Data/MyGoogleStorage");

UserCredential credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
   new ClientSecrets
   {
       ClientId = "PutYourClientIdHere",
       ClientSecret = "PutYourClientSecretHere"
   },
   new[] { DriveService.Scope.Drive },
   "user",
   CancellationToken.None,
   new FileDataStore(folder)).Result;

return credential;
