本文介绍Asp.Net Core MVC项目，连接IdentityServer4项目实现授权登录。

1、新建IdentityServer4项目，选择In-Memory项目模板。

 

 

 

2、将launchSetting.json修改URL，http://localhost:5001

 

 

 

 3、修改Startup文件

 public class Startup
    {
        public IWebHostEnvironment Environment { get; }
        public IConfiguration Configuration { get; }

        public Startup(IWebHostEnvironment environment, IConfiguration configuration)
        {
            Environment = environment;
            Configuration = configuration;
        }

        public void ConfigureServices(IServiceCollection services)
        {
            services.AddControllersWithViews();

            var builder = services.AddIdentityServer()
           .AddInMemoryIdentityResources(Config.IdentityResources)
           .AddInMemoryApiScopes(Config.ApiScopes)
           .AddInMemoryClients(Config.Clients)
           .AddTestUsers(TestUsers.Users);
            // not recommended for production - you need to store your key material somewhere secure
            builder.AddDeveloperSigningCredential();

            services.AddAuthentication(options =>
            {
                options.DefaultAuthenticateScheme = CookieAuthenticationDefaults.AuthenticationScheme;
                options.DefaultChallengeScheme = CookieAuthenticationDefaults.AuthenticationScheme;
            }).AddCookie("Cookies");
        }

        public void Configure(IApplicationBuilder app)
        {
            if (Environment.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseStaticFiles();

            app.UseRouting();
            app.UseIdentityServer();
            app.UseAuthentication();
            app.UseAuthorization();
            app.UseEndpoints(endpoints =>
            {
                endpoints.MapDefaultControllerRoute();
            });
        }
    }

 

4、修改Config文件

 public static class Config
    {
        public static IEnumerable<IdentityResource> IdentityResources =>
            new IdentityResource[]
            {
                new IdentityResources.OpenId(),
                new IdentityResources.Profile(),
            };

        public static IEnumerable<ApiScope> ApiScopes =>
            new ApiScope[]
            {
                new ApiScope("scope1"),
                new ApiScope("scope2"),
            };

        public static IEnumerable<Client> Clients =>
            new Client[]
            {
                // m2m client credentials flow client
                new Client
                {
                    ClientId = "m2m.client",
                    ClientName = "Client Credentials Client",

                    AllowedGrantTypes = GrantTypes.ClientCredentials,
                    ClientSecrets = { new Secret("511536EF-F270-4058-80CA-1C89C192F69A".Sha256()) },

                    AllowedScopes = { "scope1" }
                },

                // interactive client using code flow + pkce
                new Client
                {
                    ClientId = "interactive",
                    ClientSecrets = { new Secret("49C1A7E1-0C79-4A89-A3D6-A37998FB86B0".Sha256()) },

                    AllowedGrantTypes = GrantTypes.Code,

                    RedirectUris = { "https://localhost:44300/signin-oidc" },
                    FrontChannelLogoutUri = "https://localhost:44300/signout-oidc",
                    PostLogoutRedirectUris = { "https://localhost:44300/signout-callback-oidc" },

                    AllowOfflineAccess = true,
                    AllowedScopes = { "openid", "profile", "scope2" }
                },

                 new Client
                {
                    ClientId = "mvc",
                    ClientSecrets = { new Secret("secret".Sha256()) },
                
                    AllowedGrantTypes = GrantTypes.Code,
                
                    // where to redirect to after login
                    RedirectUris = { "http://localhost:5002/signin-oidc" },
                
                    // where to redirect to after logout
                    PostLogoutRedirectUris = { "http://localhost:5002/signout-callback-oidc" },
                
                    AllowedScopes = new List<string>
                    {
                        IdentityServerConstants.StandardScopes.OpenId,
                        IdentityServerConstants.StandardScopes.Profile
                    }
                }
            };
    }

 

5、创建mvc项目

 

 

 

6、Nuget 搜索 Microsoft.AspNetCore.Authentication.OpenIdConnect 安装包

 

 

 

7、修改Startup文件

  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.AddControllersWithViews();
            JwtSecurityTokenHandler.DefaultMapInboundClaims = false;

            services.AddAuthentication(options =>
            {
                options.DefaultScheme = "Cookies";
                options.DefaultChallengeScheme = "oidc";
            })
                .AddCookie("Cookies")
                .AddOpenIdConnect("oidc", options =>
                {
                    options.Authority = "http://localhost:5001";
                    options.RequireHttpsMetadata = false;
                    options.ClientId = "mvc";
                    options.ClientSecret = "secret";
                    options.ResponseType = "code";

                    options.SaveTokens = true;
                });

            services.Configure<CookiePolicyOptions>(options =>
            {
                options.MinimumSameSitePolicy = SameSiteMode.Unspecified;
                options.OnAppendCookie = cookieContext =>
                    SetSameSite(cookieContext.Context, cookieContext.CookieOptions);
                options.OnDeleteCookie = cookieContext =>
                    SetSameSite(cookieContext.Context, cookieContext.CookieOptions);
            });
        }

        public void SetSameSite(HttpContext httpContext, CookieOptions options)
        {
            if (options.SameSite == SameSiteMode.None)
            {
                if (httpContext.Request.Scheme != "https")
                {
                    options.SameSite = SameSiteMode.Unspecified; 
                }
            }
        }

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

            //使用Cookie决策
            app.UseCookiePolicy();

            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthentication();
            app.UseAuthorization();

            app.UseEndpoints(endpoints =>
            {
                endpoints.MapDefaultControllerRoute()
                    .RequireAuthorization();
            });
        }
    }

 

8、打开MVC项目目录，bin\debug\net5.0 目录下，运行cmd命令窗口

输入   dotnet IdsClientOne.dll --urls "http://localhost:5002"

回车 启动mvc客户端  输入账号bob 密码bob，登录验证成功后跳转至客户端index页面
