IdentityServer4搭建和使用

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
             .AddCookie(options =>
             {
                 options.ExpireTimeSpan = TimeSpan.FromMinutes(60); //到期时间
                 options.Cookie.Name = "lym.Cookies";  //名称

             });

app.UseAuthentication();

var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme);//获取实例
            identity.AddClaim(new Claim(ClaimTypes.Sid, "Sid"));//添加 
            identity.AddClaim(new Claim(ClaimTypes.Name, "Name"));//添加 
            await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(identity));//保存
            var sid = HttpContext.User.Claims.SingleOrDefault(s => s.Type == ClaimTypes.Sid);//获取值
            var name = HttpContext.User.Claims.SingleOrDefault(s => s.Type == ClaimTypes.Name);
