我正在开发一个使用谷歌驱动API的网络API,在我的本地计算机上,首先运行它将我重定向到谷歌页面进行身份验证,然后工作正常。现在我想将我的代码发布到Azure,在我发布它之后,同样的功能失败了,因为我可以进行身份验证。如何在服务器上执行此身份验证?
我已经关注了.NET快速入门(https://developers.google.com/drive/api/v3/quickstart/dotnet),这是我的代码:
using (var stream =
new FileStream($@"{dir}\client_secret.json", FileMode.Open, FileAccess.Read))
{
var cred = GoogleClientSecrets.Load(stream).Secrets;
Credentials = GoogleWebAuthorizationBroker.AuthorizeAsync(
cred,
Scopes,
"user",
CancellationToken.None).Result;
}
service = new DriveService(new BaseClientService.Initializer()
{
HttpClientInitializer = Credentials,
ApplicationName = ApplicationName,
});
}

您所遵循的教程适用于.NET控制台应用程序,这是本机应用程序而非Web应用程序。 GoogleWebAuthorizationBroker
用于已安装的应用程序。它适用于localhost,因为它能够在您的计算机上生成浏览器窗口。这不适用于托管环境,因为它无法在服务器上生成Web浏览器。
您应该关注此示例Web applications
using System;
using System.Web.Mvc;
using Google.Apis.Auth.OAuth2;
using Google.Apis.Auth.OAuth2.Flows;
using Google.Apis.Auth.OAuth2.Mvc;
using Google.Apis.Drive.v2;
using Google.Apis.Util.Store;
namespace Google.Apis.Sample.MVC4
{
public class AppFlowMetadata : FlowMetadata
{
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")
});
public override string GetUserId(Controller controller)
{
// In this sample we use the session to store the user identifiers.
// That's not the best practice, because you should have a logic to identify
// a user. You might want to use "OpenID Connect".
// You can read more about the protocol in the following link:
// https://developers.google.com/accounts/docs/OAuth2Login.
var user = controller.Session["user"];
if (user == null)
{
user = Guid.NewGuid();
controller.Session["user"] = user;
}
return user.ToString();
}
public override IAuthorizationCodeFlow Flow
{
get { return flow; }
}
}
}
请注意,您可能需要更改filedatastore存储凭据的位置,该凭据取决于您具有写入权限的位置。这可以通过提供要存储它的文件夹的路径来完成。
new FileDataStore(@"c:\datastore",true)
