Xamarin 使用acr_值="；idp:Google“；使用Xmarin'；s IdentityModel.OidcClient不会跳过identityserver4上的登录页

我正在使用for xamarin oidcclient对用户进行身份验证

如果用户选择外部提供者，我想跳过登录页面，我可以在示例代码中通过添加额外的参数acr_值来做到这一点：

var result = await _oidcClient.LoginAsync(extraParameters: new { acr_values="idp:Google" });

它起作用了，但我无法实现IdentitySeler4，我的客户端配置是：

new Client
                {
                    ClientId = "mvc",
                    ClientName = "MVC Client",
                    AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,
                    RequireConsent=false,
                    AccessTokenType=AccessTokenType.Jwt,
                    AllowAccessTokensViaBrowser=true,

                    ClientSecrets = {
                        new Secret("secret".Sha256())
                    },

                    // where to redirect to after login
                    RedirectUris = { "http://192.168.1.6.nip.io:13013/Home/", "io.identitymodel.native://TrainAppCallback" },

                    // where to redirect to after logout
                    PostLogoutRedirectUris = { "http://192.168.1.6.nip.io:13013/signout-callback-oidc" },

                    AllowedScopes = new List<string>
                    {
                        IdentityServerConstants.StandardScopes.OpenId,
                        IdentityServerConstants.StandardScopes.Profile,
                        "Advancio.TrainApp.WebApi"
                    },

                    AllowOfflineAccess = true,

                    RequirePkce = true
                }

这假设您在管道中注册了具有

Google

身份验证方案的Google身份验证中间件。还要检查服务器日志。我更新了我的问题，以包括授权请求的服务器日志，AuthenticationScheme与acr_值中的名称相同，我已检查了IdentityServer4。Demo要在我的末端发现任何不同的东西，我想知道是否应该在UserService之类的地方实现重定向？！通过探索演示项目，我发现我必须自己实现这种行为，多亏了IdentityServer4示例，我找到了我需要的示例项目。
