在Xamarin应用程序中使用Identity Server

我正在尝试使Xamarin应用程序与身份服务器一起使用.我已按照以下步骤操作:

I am trying to get an Xamarin app working with Identity server. I have followed these steps:

1)下载此文件: https://github.com/IdentityModel/IdentityModel.OidcClient.Samples/tree/master/XamarinForms 2)从第1点开始运行Xamarin Forms应用程序.它按预期运行，即我可以以Bob身份登录，并且已通过面向公众的演示应用程序通过了身份验证:

1) Download this: https://github.com/IdentityModel/IdentityModel.OidcClient.Samples/tree/master/XamarinForms 2) Run the Xamarin Forms app from point 1. It works as expected i.e. I can login as Bob and I am authenticated against the public facing demo app: https://demo.identityserver.io

到现在为止，它都按预期工作.

It works as expected up to here.

3)然后，我在此处下载面向公众的演示应用程序: https://github.com/IdentityServer/IdentityServer4.Demo .将其添加到Xamarin解决方案中. 4)在解决方案中；查找并替换-从 https://demo.identityserver.io 到

3) I then download the public facing demo app here: https://github.com/IdentityServer/IdentityServer4.Demo. Add it to the Xamarin solution. 4) In the solution; do a find and replace - from https://demo.identityserver.io to http://localhost:24997/ (this is the URL of my identity server inside the solution).

5)注释掉以下代码行，因为我没有使用Azure:

5) Comment out the following lines of code as I am not using Azure:

//Startup.cs
 //.AddGoogle("Google", options =>
                //{
                //    options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;

                //    options.ClientId = Configuration["Secret:GoogleClientId"];
                //    options.ClientSecret = Configuration["Secret:GoogleClientSecret"];
                //})
                //.AddOpenIdConnect("aad", "Sign-in with Azure AD", options =>
                //{
                //    options.Authority = "https://login.microsoftonline.com/common";
                //    options.ClientId = "https://leastprivilegelabs.onmicrosoft.com/38196330-e766-4051-ad10-14596c7e97d3";

                //    options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;
                //    options.SignOutScheme = IdentityServerConstants.SignoutScheme;

                //    options.ResponseType = "id_token";
                //    options.CallbackPath = "/signin-aad";
                //    options.SignedOutCallbackPath = "/signout-callback-aad";
                //    options.RemoteSignOutPath = "/signout-aad";

                //    options.TokenValidationParameters = new TokenValidationParameters
                //    {
                //        ValidateIssuer = false,
                //        ValidAudience = "165b99fd-195f-4d93-a111-3e679246e6a9",

                //        NameClaimType = "name",
                //        RoleClaimType = "role"
                //    };
                //})

//Program.cs
//.ConfigureAppConfiguration((ctx, builder) =>
//{
//    var config = builder.Build();
//    var tokenProvider = new AzureServiceTokenProvider();
//    var kvClient = new KeyVaultClient((authority, resource, scope) => tokenProvider.KeyVaultTokenCallback(authority, resource, scope));
//    builder.AddAzureKeyVault(config["KeyVault:BaseUrl"], kvClient, new DefaultKeyVaultSecretManager());
//})

6)添加选项.RequireHttpsMetadata = false;到IdentityServer.Startup.

6) Add options.RequireHttpsMetadata = false; to IdentityServer.Startup.

然后我运行Xamarin应用程序和身份服务器.我在Xamarin应用程序的第一行(MainPage.Login_Clicked的第一行)中看到以下错误:

I then run the Xamarin app and the Identity server. I see an error on the following line inside the Xamarin app (first line of: MainPage.Login_Clicked):

_result = await _client.LoginAsync(new LoginRequest());

错误是:Error connecting to http://localhost:24997/.well-known/openid-configuration

有什么明显的地方我做错了吗?

Is there anything obvious that I am doing wrong?
