Google日历Api在本地工作正常，但未在服务器上提升其身份验证

我已在console.developers.google.com创建了一个项目以使用Google Calendar API。我们需要生成凭证并选择应用程序类型

对于Localhost和应用程序类型other以下是Json，它可以正常工作。

{
    "installed": {
    "client_id": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com",
    "project_id": "xxxxxx-00000",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_secret": "xxxxxxxxxxxx",
    "redirect_uris": [ "urn:ietf:wg:oauth:2.0:oob", "http://localhost" ]
    }
}

对于应用程序类型Web Application到服务器上的主机很少参数在Json中具有不同的值，如下所示。

{
    "web": {
    "client_id": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com",
    "project_id": "xxxxxxxx-99999",
    "auth_uri": "https://accounts.google.com/o/oauth2/auth",
    "token_uri": "https://accounts.google.com/o/oauth2/token",
    "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
    "client_secret": "xxxxxxxxxxxxxxxxxxxxxxx",
    "redirect_uris": [ "http://demo.mydemo.com" ],
    "javascript_origins": [ "http://demo.mydemo.com" ]
    }
}

此时，当用户（仅限已集成Google日历的用户）尝试创建活动时，Google应同意使用哪个Google帐户，并在重定向到重定向页面之前要求阅读个人数据。 在同意后，它将在所选谷歌帐户的日历中添加提供的数据。问题是它没有将用户重定向到Oauth身份验证，即The Consent Screen。

Image Of Consent Screen  任何人都可以帮我解决这个问题吗？

错误如下

var credential = GoogleWebAuthorizationBroker.AuthorizeAsync(GoogleClientSecrets.Load(stream).Secrets,
                                                                             scopes,
                                                                             userName,
                                                                             CancellationToken.None,
                                                                             new FileDataStore(credPath, true)).Result;

用于已安装的应用程序。当您在调试模式下运行代码时，它可能会起作用，因为您可以在本地计算机上打开Web浏览器。但是，当您尝试将其托管在服务器上时，由于您无法在服务器上打开Web浏览器，因此您无法工作，而是在客户端计算机上打开Web浏览器。 

private static readonly IAuthorizationCodeFlow flow =
            new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
                {
                    ClientSecrets = new ClientSecrets
                    {
                        ClientId = "PUT_CLIENT_ID_HERE",
                        ClientSecret = "PUT_CLIENT_SECRET_HERE"
                    },
                    Scopes = new[] { DriveService.Scope.Drive },
                    DataStore = new FileDataStore("Drive.Api.Auth.Store")
                });

您应该尝试遵循这篇文章。 Google Oauth2 asp.net MVC
