c# - 托管在 ASP.NET Core 项目上的 Blazor Webassembly 项目中的身份验证问题

问题描述

我有两个项目：

Notes.Server- ASP.NET Core 项目，
Notes.Client- Blazor WASM 项目

我的笔记应用程序包含Client.cshtml具有以下内容的页面：

<component type="typeof(PrettyNotes.Web.Client.App)" render-mode="WebAssemblyPrerendered"/>

它预装了 Blazor WASM。我在这个预渲染项目中实现了 oidc 身份验证。

Notes.Server 的Startup.cs文件：

            services.AddDbContext<PrettyNotesApplicationDBContext>(options =>

                    new[]
                    {
                        new IdentityServer4.Models.Client
                        {
                            ClientId = "PrettyNotesClient",
                            AllowedGrantTypes = GrantTypes.Code,

                            Enabled = true
                        }
                    })
                .AddInMemoryIdentityResources(
                    new IdentityResource[]
                    {
                        new IdentityResources.Address(),
                        new IdentityResources.Profile(),
                        new IdentityResources.Email(),

            services.AddScoped<AuthenticationStateProvider, ServerAuthenticationStateProvider>().AddScoped<SignOutSessionStateManager>();
            services.AddRemoteAuthentication<RemoteAuthenticationState, RemoteUserAccount, OidcProviderOptions>();
        }

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

            app.UseRouting();
            app.UseStaticFiles();
            app.UseBlazorFrameworkFiles();

            app.UseAuthentication();
            app.UseAuthorization();
            app.UseIdentityServer();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapControllers();
                endpoints.MapRazorPages();
                endpoints.MapFallbackToController("/client/{**segment}", "Index", "Client");
                endpoints.MapControllerRoute(
                    name: "default",
                    pattern: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

我的 Blazor WASM 项目在服务器中预渲染。当我尝试访问预渲染 Blazor 的 Blazor WASM 项目页面时，出现下一个错误：

fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[1]
      An unhandled exception has occurred while executing the request.
      System.InvalidCastException: Unable to cast object of type 'Microsoft.AspNetCore.Components.Server.ServerAuthenticationStateProvider' to type 'Microsoft.AspNetCore.Components.WebAssembly.Authentication.IRemoteAuthenticationService`1[Microsoft.AspNetCore.Components.WebAssembly.Authentication.RemoteAuthenticationState]'.

如何解决这个问题？您能否推荐一些关于 Prerendered Blazor Webassembly 中的身份验证的资源和存储库？
