二、IDS4配置服務

 它是根據定義配置服務Config.cs文件來生成客戶端和API使用該服務所需的配置數據。

一、IDS4簽名服務

1、為項目添加NuGet包。

2、IDS4服務制定的配置Config.cs。

using IdentityServer4.Models;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace ids4
{
    //一、IDS4服務制定
    public class Config
    {
        //1、定義API資源
        public static IEnumerable<ApiResource> GetApis() //ApiResource是屬於using IdentityServer4.Models;內的。
        {
            return new List<ApiResource>
            {
                new ApiResource("api1", "My API")
            };
        }
        //2、定義客戶端
        public static IEnumerable<Client> GetClients()
        {
            return new List<Client>
            {
                new Client
                {
                    ClientId = "client",
                    // no interactive user, use the clientid/secret for authentication
                    AllowedGrantTypes = GrantTypes.ClientCredentials,
                    // secret for authentication
                    ClientSecrets =
                    {
                       new Secret("secret".Sha256())
                    },
                    // scopes that client has access to
                    AllowedScopes = { "api1" }
                }
            };
        }
    }
}　

3、Startup.cs內添加IDS4服務。

using IdentityServer4.Models;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

namespace ids4
{
    //二、添加IDS4服務
    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.Configure<CookiePolicyOptions>(options =>
            {
                // This lambda determines whether user consent for non-essential cookies is needed for a given request.
                options.CheckConsentNeeded = context => true;
                options.MinimumSameSitePolicy = SameSiteMode.None;
            });


            services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

            //1、注入服務添&加在最底部
            var builder = services.AddIdentityServer()
            //.AddInMemoryIdentityResources(Config.GetIdentityResources())  //注入GetIdentityResources資源。
            .AddInMemoryApiResources(Config.GetApis()) //注入ApiResources資源對應定義的API資源。
            .AddInMemoryClients(Config.GetClients());  //注入定義的客戶端
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            app.UseIdentityServer();//2、添加服務&添加在頂部

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

            app.UseHttpsRedirection();
            app.UseStaticFiles();
            app.UseCookiePolicy();

            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=Index}/{id?}");
            });
        }
    }
}

4、運行服務器並瀏覽瀏覽器 http://localhost:5000/.well-known/openid-configuration 您應該會看到所謂的發現文檔。客戶端和API將使用它來下載必要的配置數據。
