客户端集成IdentityServer4

1. vs code 终端执行  dotnet new webapi --name ClientCredentialApi

2. 找到ValuesController.cs

引用  using Microsoft.AspNetCore.Authorization;

    [Authorize]
    [Route("api/[controller]")]
    [ApiController]
    public class ValuesController : ControllerBase
    {
    }

3. Nuget 导入 IdentityServer4.AccessTokenValidation

4. 修改 Startup.cs 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.HttpsPolicy;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Logging;
using Microsoft.Extensions.Options;

namespace ClientCredentialApi
{
    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)
        {

            //注册Authentication
            services.AddAuthentication("Bearer").AddIdentityServerAuthentication(options =>
            {
                options.Authority = "https://localhost:5000";
                options.RequireHttpsMetadata = false;
                options.ApiName = "api";
            });

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

        // 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();
            }
            else
            {
                app.UseHsts();
            }

            app.UseHttpsRedirection();

            app.UseAuthentication();

            app.UseMvc();
        }
    }
}

5. 启动 " IdentityServer4 登陆中心服务 " ，使用PostMan 调用 http://localhost:5003/connect/token

参数

client_id:client
client_secret:secrt
grant_type:client_credentials

6. 把当前项目也启动，进行验证 , 客户端验证整个过程没有任何毛病
