我可以在WebApi身份验证管道中添加第二个IdentityServer4吗？

Question

我有一个WebApi（DemoService）。我使用IdentityServer4保护它。如果我使用Bearer令牌请求Api，我的DemoService会发出一些请求，以确保我可以访问DemoService。

1. 获取http://192.168.178.20:5200/.well-known/openid-configuration
2. 获取http://192.168.178.20:5200/.well-known/openid-configuration/jwks

在默认情况下，我的DemoService仅针对一个IdentityServer4进行授权，并且everthing运行良好。是否可以使IdentityServer4的URL（192.168.178.20:5200）具有灵活性，以对第二个IdentityServer4进行授权？或者是否可以添加第二个IdentityServer4。

这是我的Startup.cs：

namespace DemoService
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvcCore()
                .AddAuthorization()
                .AddJsonFormatters();

            services.AddAuthentication("Bearer")
                .AddIdentityServerAuthentication(options =>
                {
                    // can I decide in the current
                    // Request which Authority to use?
                    // I want to switch the url between two
                    // IdentityServers
                    options.Authority ="http://192.168.178.20:5200"; 
                    options.RequireHttpsMetadata = false;

                    options.ApiName = "DemoService";
                });

            //// If I try to add a second IdentityServer I
            //// get the following failure:
            //// System.InvalidOperationException: 'Scheme already exists: BearerIdentityServerAuthenticationJwt'
            // services.AddAuthentication("Bearer")
            //     .AddIdentityServerAuthentication(options =>
            //     {
            //         options.Authority ="http://localhost:5000"; 
            //         options.RequireHttpsMetadata = false;
            //         options.ApiName = "DemoService";
            //     });


        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseAuthentication();

            app.UseMvc();
        }
    }
}
