如何在 Web api 中启用 windows 身份验证和 Owin 令牌身份验证?

How to enable windows authentication in conjunction with Owin token authentication in web api?

我正在开发 Web api 应用程序,我需要按以下方式检查经过身份验证的用户:

1) 使用 Windows 身份验证

对用户进行身份验证

2) 如果未在 Windows 中进行身份验证。我将尝试使用 Owin 访问令牌.

对用户进行身份验证

我的代码可以正常工作,但是当我启用 Windows 身份验证时,如下所示:

 public static IAppBuilder EnableWindowsAuthentication(this IAppBuilder app)
    {
        if (!app.Properties.TryGetValue("System.Net.HttpListener", out var val))
            return app;

        if (val is HttpListener listener)
        {
            listener.AuthenticationSchemes = AuthenticationSchemes.IntegratedWindowsAuthentication;
        }
        return app;
    }

然后里面 Startup.cs:

public void Configuration(IAppBuilder app)
    {
        OnAppDisposing(app);
        ConfigureOAuth(app);

        var config = new HttpConfiguration();
        var webApiConfiguration = WebApiConfig.Register(config);

        app.UseCors(CorsOptions.AllowAll);
        app.EnableWindowsAuthentication();
        //here some owin middlewares

        app.UseWebApi(webApiConfiguration);

    }
 private void ConfigureOAuth(IAppBuilder app)
    {
        OAuthBearerOptions = new OAuthBearerAuthenticationOptions();

        OAuthAuthorizationServerOptions OAuthServerOptions = new OAuthAuthorizationServerOptions()
        {
            AllowInsecureHttp = true,
            TokenEndpointPath = new PathString("/api/token"),
            AccessTokenExpireTimeSpan = TimeSpan.FromMinutes(60),
            Provider = new SimpleAuthorizationServerProvider()
        };

        // Token Generation

        app.UseOAuthBearerAuthentication(OAuthBearerOptions);
        app.UseOAuthAuthorizationServer(OAuthServerOptions);
      }

如果我尝试使用 Bearer 令牌调用授权端点,我会得到 401 UnAuthorized

所以我的问题是:如何解决这种情况并使两种身份验证方法协同工作?

我是这样解决的:

SimpleAuthorizationServerProvider class 内部 GrantResourceOwnerCredentials 方法中,我将使用以下代码检查 Active Directory 中的用户:

public string FindUser(string activeDirectoryPath ,string userName, string password)
    {
        try
        {

                using (var searcher = new DirectorySearcher(new DirectoryEntry(activeDirectoryPath, userName, password)))
                {
                    searcher.Filter = string.Format("(&(objectClass=user)(name={0}))", userName);
                    searcher.PropertiesToLoad.Add("name");// username
                    var activeDirectoryStaff = searcher.FindOne();
                    if (activeDirectoryStaff != null)
                    {
                        return (string)activeDirectoryStaff.Properties["name"][0];
                    }
                    else
                        return null;
                }
            }

        }
        catch (Exception ex)
        {
            this.Log().Error(ex, ex.Message);
            return null;
        }
        return null;
    }

如果上面的方法return为null,那么我会return 401 UnAuthorized .
