ASP.net Core 登陆验证CookieAuthenticationDefaults/ClaimsPrincipal

一、在StartUp中注册服务

public IServiceProvider ConfigureServices(IServiceCollection services)
{
            services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
                    .AddCookie(options => options.LoginPath = new             
                     PathString("/Login/Index")); //登陆页面
            services.AddMvc();
            this.ApplicationContainer = AutoFacIoc.Injection(services);
            return new AutofacServiceProvider(this.ApplicationContainer);
}

		// 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();
			}
            //使用静态文件
            app.UseStaticFiles();
            //启用登陆验证
            app.UseAuthentication();
            //路由
            app.UseMvc(routes =>
            {
                routes.MapRoute(
                    name: "default",
                    template: "{controller=Home}/{action=HomeIndex}/{id=0}");
            });

		}

二、登陆

        [OperationLogFilter("Select")]
        public IActionResult Index(string returnUrl = null) //登陆成功回退页面
        {
            TempData["returnUrl"] = returnUrl;
            return View();
        }

        [HttpPost]
        [OperationLogFilter("Login",Tag ="登陆")]
        public async Task<IActionResult> Login(ApplicationUser user, string returnUrl = null)
        {
           //做参数验证！！！ 和用户信息认证

            var identity = new ClaimsIdentity(CookieAuthenticationDefaults.AuthenticationScheme);
            //可以放用户唯一标识。 然后再BaseController中使用User.Identity.Name获取， 再查询数据库/缓存获取用户信息
            identity.AddClaim(new Claim(ClaimTypes.Name, lookupUser.UserName)); //取值 User.Identity.Name
            identity.AddClaim(new Claim(ClaimTypes.UserData, "456465465456")); // User.Claims.Select(t => new { t.Type, t.Value }).ToList();
            identity.AddClaim(new Claim(ClaimTypes.Surname, "王小二"));
            identity.AddClaim(new Claim(ClaimTypes.NameIdentifier, "123"));

            await HttpContext.SignInAsync(CookieAuthenticationDefaults.AuthenticationScheme, new ClaimsPrincipal(identity));

            return RedirectToAction(nameof(HomeController.HomeIndex), "Home");
        }

三、登出

public async Task<IActionResult> Logout()
{
            await HttpContext.SignOutAsync(CookieAuthenticationDefaults.AuthenticationScheme);
            return RedirectToAction("HomeIndex", "Home");
}

四、获取登陆信息

        [AuthFilter]
        public IActionResult HomeIndex()
        {
            string a  = User.Identity.Name; //一般用于存储用户唯一标识
            string type = User.Identity.AuthenticationType; //验证方式
            var temp = User.Claims.Select(t => new { t.Type, t.Value }).ToList();
            var tt= temp[0].Type;
            return  View();
        }
