Question

注意：在解决重定向问题后，我遇到了另一个问题，即收到错误＆＃34;无法将Newtonsoft.Json.Linq.JArray转换为Newtonsoft.Json.Linq.JToken＆＃34;。所以在我的回答中，我为两者提供了正确的解决方案。

我有身份服务器项目和客户端项目，一切都可以进行身份验证而不会出现任何问题，甚至可以重定向到正确的客户端URL，但是网址为：＆＃34; https://localhost:44309/signin-oidc＆＃34;给出空白页。

注意：为Identity Server和客户端应用程序启用了SSl。

正如预期的那样验证用户，如下面的屏幕截图所示。我的标识服务器包含客户端的以下配置值。

                // OpenID Connect hybrid flow and client credentials client (MVC)
            new Client
            {
                ClientId = "mvc",
                ClientName = "MVC Client",
                AllowedGrantTypes = GrantTypes.HybridAndClientCredentials,
                ClientSecrets =
                {
                    new Secret("secret".Sha256())
                },

                RedirectUris = { /*"http://localhost:5002/signin-oidc",*/"https://localhost:44309/signin-oidc" },
                PostLogoutRedirectUris = { /*"http://localhost:5002/signout-callback-oidc",*/"https://localhost:44309/signout-callback-oidc" },

                AllowedScopes = 
                {
                    IdentityServerConstants.StandardScopes.OpenId,
                    IdentityServerConstants.StandardScopes.Profile,
                    //"api1"
                },
                AllowOfflineAccess = true
            }

startup.cs如下。

        public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        // configure identity server with in-memory stores, keys, clients and scopes
        services.AddIdentityServer()
            .AddDeveloperSigningCredential()
            .AddInMemoryIdentityResources(Config.GetIdentityResources())
            .AddInMemoryApiResources(Config.GetApiResources())
            .AddInMemoryClients(Config.GetClients())
            .AddTestUsers(Config.GetUsers());

        services.AddAuthentication()
            //.AddGoogle("Google", options =>
            //{
            //    options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;

            //    options.ClientId = "434483408261-55tc8n0cs4ff1fe21ea8df2o443v2iuc.apps.googleusercontent.com";
            //    options.ClientSecret = "3gcoTrEDPPJ0ukn_aYYT6PWo";
            //})
            .AddOpenIdConnect("oidc", "dataVail Login", options =>
            {
                options.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme;

                options.SignOutScheme = IdentityServerConstants.SignoutScheme;

                options.Authority = "https://login.microsoftonline.com/d0e2ebcc-0961-45b2-afae-b9ed6728ead7";//"https://demo.identityserver.io/";
                options.ClientId = "f08cc131-72da-4831-b19d-e008024645e4";
                options.UseTokenLifetime = true;
                options.CallbackPath = "/signin-oidc";
                options.RequireHttpsMetadata = false;

                options.TokenValidationParameters = new TokenValidationParameters
                {
                    NameClaimType = "name",
                    RoleClaimType = "role"
                };
            });
    }

        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
    {
        if (env.IsDevelopment())
        {
            app.UseDeveloperExceptionPage();
        }

        app.UseForwardedHeaders(new ForwardedHeadersOptions
        {
            ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
        });

        app.Use(async (context, next) =>
        {
            context.Request.Scheme = "https";
            await next.Invoke();
        });
        app.UseIdentityServer();

        app.UseStaticFiles();
        app.UseMvcWithDefaultRoute();
    }

这是我的客户端应用程序的startup.cs

        public void ConfigureServices(IServiceCollection services)
    {
        services.AddMvc();

        JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();

        services.AddAuthentication(options =>
        {
            options.DefaultScheme = "Cookies";
            options.DefaultChallengeScheme = "oidc";
        })
            .AddCookie("Cookies")
            .AddOpenIdConnect("oidc", options =>
            {
                options.SignInScheme = "Cookies";

                options.Authority = "https://localhost:44392/";
                options.RequireHttpsMetadata = false;

                options.ClientId = "mvc";
                options.ClientSecret = "secret";
                options.ResponseType = "code id_token";

                options.SaveTokens = true;
                options.GetClaimsFromUserInfoEndpoint = true;

                //options.Scope.Add("api1");
                options.Scope.Add("offline_access");

            });
    }

任何人都可以帮我解决这个问题。

我可以在Identity Server 4人员的帮助下解决这个问题。如果有人遇到这个问题就是解决方案。

我错过了添加＆＃34; UseAuthentication＆＃34;在配置客户端MVC管道。所以在添加后我按预期重定向，然后我有另一个问题，如下所示。

System.InvalidCastException: Cannot cast Newtonsoft.Json.Linq.JArray to Newtonsoft.Json.Linq.JToken. at Microsoft.AspNetCore.Authentication.RemoteAuthenticationHandler1.d__12.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
at System.Runtime.CompilerServices.TaskAwaiter1.GetResult() at Microsoft.AspNetCore.Authentication.AuthenticationMiddleware.<Invoke>d__6.MoveNext() --- End of stack trace from previous location where exception was thrown --- at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) at Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.<Invoke>d__7.MoveNext()

我将使用AzureAD作为外部身份验证提供程序将我的应用程序连接到IdentityServer4时遇到此异常。我的应用程序使用Hybrid流程连接到IdentityServer4。我被正确地重定向到Azure，登录，并且代码和id_tokens被正确发布。调用userInfo端点时，在我的应用程序中引发此异常。

为了解决这个问题，我必须删除名称两次的声明。

我确认AAD发出了两个名称声明。删除其中一个可以解决问题。

var namesClaim = externalUser.FindFirst(ClaimTypes.Name) ??
                             throw new Exception("Unknown names");

if (namesClaim!=null)
{
    claims.Remove(namesClaim);
}

希望这可以帮助某人。

Answer 2

我在担任多个职务时遇到了同样的问题。这是解决方案：

.AddOpenIdConnect("oidc", options =>
{
    // ...
    options.Scope.Add("roles");

    // ... using MapJsonKey instead of MapUniqueJsonKey for having 2 or more roles
    options.ClaimActions.MapJsonKey(claimType: "role", jsonKey: "role");
});

从身份服务器4重定向URL的行为不符合预期，并且＆＃34;无法将Newtonsoft.Json.Linq.JArray转换为Newtonsoft.Json.Linq.JToken＆＃34;错误
