IdentityServer4 相对 IdentityServer3 在界面上要简单一些，拷贝demo基本就能搞定，做样式修改就行了

之前的文章已经有登录Idr4服务端操作了，新建了一个自己的站点 LYM.WebSite,项目中用的是Idr4源码处理

 #region 添加授权验证方式 这里是Cookies & OpenId Connect JwtSecurityTokenHandler.DefaultInboundClaimTypeMap.Clear();services.AddAuthentication(options =>{options.DefaultScheme = "lym.Cookies";options.DefaultChallengeScheme = "oidc";}).AddCookie("lym.Cookies")  //监控浏览器Cookies不难发现有这样一个 .AspNetCore.lym.Cookies 记录了加密的授权信息 .AddOpenIdConnect("oidc", options =>{options.SignInScheme = "lym.Cookies";options.Authority = customUrl;options.ClientId = "lym.clienttest1";options.ClientSecret = "lym.clienttest";options.RequireHttpsMetadata = false;options.SaveTokens = true;options.ResponseType = "code id_token";//布尔值来设置处理程序是否应该转到用户信息端点检索。额外索赔或不在id_token创建一个身份收到令牌端点。默认为“false”options.GetClaimsFromUserInfoEndpoint = true;options.Scope.Add("cloudservices");});#endregion

写好相关配置就OK了，附上源码

部分源码

那么实际调用过程中怎么使用自己的业务逻辑代码来实现登录来，Idr4 Demo中已经加入了登录服务代码，只需要加如到我们的项目中做一些修改就行

AccountService

接下来就是定义我们自己的控制器类了，调用自己的业务只需要DI自己的接口服务就行了以及Idr4相关接口，非常简单

如：

IIdentityServerInteractionService

IEventService

IUserService //自定义业务数据库用户服务处理用户名密码等业务逻辑

自需要在构造函数中DI,然后将对象添加实例化传递到AccountService中做后续处理
