Oauth2 使用 ASP .net core MVC 登录 Google api [英] Oauth2 login to Google api with ASP .net core MVC

问题描述

我一直在关注 网络应用程序(ASP.NET MVC) 尝试连接到 Google API 之一.

I have been following Web applications (ASP.NET MVC) Attempting to connect to one of the Google APIs.

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; }
        }
    }
}

该示例似乎不适用于 .net 核心，因为它找不到 FlowMetadata

The sample doesn't appear to work with .net core as it cant find FlowMetadata

推荐答案

问题是上述示例不是为 .net core 设计的.

The problem is that the above sample was not designed for .net core.

clientinfo.cs

/// <summary>
    /// Client auth information, loaded from a Google user credential json file.
    /// Set the TEST_CLIENT_SECRET_FILENAME environment variable to point to the credential file.
    /// </summary>
    public class ClientInfo
    {
        public static ClientInfo Load()
        {
            const string ClientSecretFilenameVariable = "TEST_CLIENT_SECRET_FILENAME";
            string clientSecretFilename = Environment.GetEnvironmentVariable(ClientSecretFilenameVariable);
            if (string.IsNullOrEmpty(clientSecretFilename))
            {
                throw new InvalidOperationException($"Please set the {ClientSecretFilenameVariable} environment variable before running tests.");
            }
            var secrets = JObject.Parse(Encoding.UTF8.GetString(File.ReadAllBytes(clientSecretFilename)))["web"];
            var projectId = secrets["project_id"].Value<string>();
            var clientId = secrets["client_id"].Value<string>();
            var clientSecret = secrets["client_secret"].Value<string>();
            return new ClientInfo(projectId, clientId, clientSecret);
        }

        private ClientInfo()
        {
            Load();
        }


        private ClientInfo(string projectId, string clientId, string clientSecret)
        {
            ProjectId = projectId;
            ClientId = clientId;
            ClientSecret = clientSecret;
        }

        public string ProjectId { get; }
        public string ClientId { get; }
        public string ClientSecret { get; }
    }

Program.cs

 public class Program
    {
        public static void Main(string[] args)
        {
            BuildWebHost(args).Run();
        }

        public static IWebHost BuildWebHost(string[] args)
        {
            var clientInfo = ClientInfo.Load();

            return WebHost.CreateDefaultBuilder(args)
                .UseStartup<Startup>()
                .ConfigureServices(services =>
                {
                    services.AddSingleton(clientInfo);
                })
                .Build();
        }
    }

startup.cs 配置服务

 services.AddAuthentication(options =>
                {
                    options.DefaultScheme = "Cookies";
                    options.DefaultChallengeScheme = "Google";
                })
                .AddCookie("Cookies")
                .AddGoogleOpenIdConnect("Google", options =>
                {
                    var clientInfo = (ClientInfo)services.First(x => x.ServiceType == typeof(ClientInfo)).ImplementationInstance;
                    options.ClientId = clientInfo.ClientId;
                    options.ClientSecret = clientInfo.ClientSecret;
                    options.Scope.Add("profile");   

                });

        }

添加以下配置以及 app.UseAuthentication();

add the following to configure as well app.UseAuthentication();

控制器

[GoogleScopedAuthorize("https://www.googleapis.com/auth/analytics.readonly")]
        public async Task<IActionResult> GoogleAnalyticsReport([FromServices] IGoogleAuthProvider auth, [FromServices] ClientInfo clientInfo, long ViewId)
        {
            var cred = await auth.GetCredentialAsync();
            var service = new AnalyticsReportingService(new BaseClientService.Initializer
            {
                HttpClientInitializer = cred
            });

退出

 public async Task<IActionResult> Logout()
    {
        await HttpContext.SignOutAsync();
        return RedirectToAction("Index");
    }

它现在正在登录我的用户，我可以请求数据.

Its now logging my user in and i can request data.
