Question

我是.net核心世界的新手，我正在尝试设置一个identityServer。我按照https://identityserver4.readthedocs.io/en/release/quickstarts/6_aspnet_identity.html的指南进行操作，并设法使基础工作正常。我现在想要将.Net核心身份与identityServer结合使用，但它提供了一个例外，我不知道如何解决。例外：

没有配置身份验证处理程序来验证方案：idsrv

 Executed action IdentityServer4.Quickstart.UI.GrantsController.Index (IdentityServer) in 22.9784ms
fail: Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware[0]
      An unhandled exception has occurred while executing the request
System.InvalidOperationException: No authentication handler is configured to authenticate for the scheme: idsrv
   at Microsoft.AspNetCore.Http.Authentication.Internal.DefaultAuthenticationManager.<GetAuthenticateInfoAsync>d__12.MoveNext()
--- End of stack trace from previous location where exception was thrown ---
   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()

我曾尝试浏览github问题以解决类似问题，有些人说它与IdentityServer和Identity的加载顺序有关。但在我的情况下，他们应该是正确的？

我的Startup.cs课程：

 public void ConfigureServices(IServiceCollection services)
        {

            services.AddDbContext<ApplicationDbContext>(options =>
                options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));

            services.AddIdentity<IdentityUser, IdentityRole>()
                .AddEntityFrameworkStores<ApplicationDbContext>()
                .AddDefaultTokenProviders();

            services.AddMvc();

            // Adds IdentityServer
            services.AddIdentityServer()
                .AddTemporarySigningCredential()
                .AddInMemoryIdentityResources(Resources.GetIdentityResources())
                .AddInMemoryApiResources(Resources.GetApiResources())
                .AddInMemoryClients(Clients.Get())
                .AddAspNetIdentity<IdentityUser>();

        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
        {

            loggerFactory.AddConsole(Configuration.GetSection("Logging"));
            loggerFactory.AddDebug();

            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
                app.UseBrowserLink();
            }
            else
            {
                app.UseExceptionHandler("/Home/Error");
            }

            app.UseIdentity();

            // Adds IdentityServer
            app.UseIdentityServer();

            app.UseStaticFiles();

            app.UseMvcWithDefaultRoute();
        }

Answer 1

尝试将此添加到您的app.UseCookieAuthentication(new CookieAuthenticationOptions { AuthenticationScheme = "idsrv", // Matches the name it's looking for in the exception AutomaticAuthenticate = true, AutomaticChallenge = true });方法：

Program

Answer 2

您还需要在Configure（）方法中设置cookie中间件。

app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationScheme = AuthenticationSchemeConstants.DefaultCookieAuthenticationScheme,
        CookieName = $"{AuthenticationSchemeConstants.CookiePrefixName}.auth",
        ExpireTimeSpan = TimeSpan.FromMinutes(20),
        SlidingExpiration = true,
        AutomaticAuthenticate = false,
        AutomaticChallenge = false
    });

    app.UseCookieAuthentication(new CookieAuthenticationOptions
    {
        AuthenticationScheme = AuthenticationSchemeConstants.ExternalCookieAuthenticationScheme,
        AutomaticAuthenticate = false,
        AutomaticChallenge = false
    });

    app.UseIdentityServer();

希望有所帮助

Answer 3

.NET core 2.0 提供程序中的

AuthenticationOptions类不再定义AuthenticationScheme属性。

在1.x中，AutomaticAuthenticate和AutomaticChallenge属性旨在设置在单个身份验证方案上

在2.0中，这两个属性已作为单个AuthenticationOptions实例上的标志删除，并已移至基本AuthenticationOptions类中。可以在Startup.cs的ConfigureServices方法中的AddAuthentication方法调用中配置属性：

在调用Use Provider 身份验证方法在ConfigureServices 方法

中时，应配置

authenticationScheme

services
   .AddAuthentication(opts =>{
       opts.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
    }) 
   .AddCookie("idsrv", opts =>
    {
        //AuthenticationScheme = "idsrv",
        //AutomaticAuthenticate = true,
        //AutomaticChallenge = true
    })

没有为该方案配置身份验证处理程序：idsrv
