ASP.NET Core 中简单Session登录校验：从Session的配置添加、到请求过滤、再到页面操作。推荐相关阅读：ASP.NET 会话状态概述 ASP.NET Cookie 概述 ASP.NET 状态管理建议 ASP.NET Core 中的会话和应用状态

添加Session配置服务
配置session超时时间30分钟。
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);
// 添加用户Session服务
//services.AddSession();
services.AddSession(options =>
{
options.IdleTimeout = TimeSpan.FromMinutes(30);
options.Cookie.HttpOnly = true;
});
// 指定Session保存方式:分发内存缓存
services.AddDistributedMemoryCache();
}启用Session配置
注意放置代码的顺序，Session必须在MVC之前。

// 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.UseExceptionHandler("/Home/Error");
app.UseHsts();
}
app.UseHttpsRedirection();
//使用静态文件
app.UseStaticFiles();
//Cookie策略
//app.UseCookiePolicy();
//Session
app.UseSession();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
// template: "{controller=Home}/{action=Index}/{id?}");
//template: "{controller=Home}/{action=Server}/{id?}");
template: "{controller=Login}/{action=SignIn}/{id?}");
});
}添加用户模型
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Threading.Tasks;
namespace RTVSWeb.Models
{
public class UserModel
{
[Required(ErrorMessage = "用户名不能为空")]
public string Username { get; set; }
[Required(ErrorMessage = "密码不能为空")]
[DataType(DataType.Password)]
public string Password { get; set; }
public bool RememberMe { get; set; }
}
}
添加登录控制器
此类提供登录校验和退出。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using RTVSWeb.Models;
using RTVSWeb.Utils;
// For more information on enabling MVC for empty projects, visit https://go.microsoft.com/fwlink/?LinkID=397860
namespace RTVSWeb.Controllers
{
public class LoginController : Controller
{
// GET: /<controller>/
public IActionResult SignIn(UserModel userModel)
{
if (ModelState.IsValid)
{
//检查用户信息
if (userModel.Username.Equals("rtvsweb") && userModel.Password.Equals("cvnavi2018"))
{
//记录Session
HttpContext.Session.Set("User", ByteConvertHelper.Object2Bytes(userModel));
//跳转到系统首页
return RedirectToAction("Server", "Home");
}
ViewBag.ErrorInfo = "用户名或密码错误";
return View(userModel);
}
ViewBag.ErrorInfo = ModelState.Values.First().Errors[0].ErrorMessage;
return View(userModel);
}
public IActionResult SignOut()
{
//清除Session
HttpContext.Session.Clear();
//跳转到系统登录界面
return RedirectToAction("SignIn", "Login");
}
}
}
控制器基础类
此类是提供给其他需要登录验证的Controller进行继承。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Microsoft.AspNetCore.Mvc.Filters;
// For more information on enabling MVC for empty projects, visit https://go.microsoft.com/fwlink/?LinkID=397860
namespace RTVSWeb.Controllers
{
public class BaseController : Controller
{
/// <summary>
/// 请求过滤处理
/// </summary>
/// <param name="filterContext"></param>
public override void OnActionExecuting(ActionExecutingContext filterContext)
{
byte[] result;
filterContext.HttpContext.Session.TryGetValue("User", out result);
if (result == null)
{
filterContext.Result = new RedirectResult("/Login/SignIn");
return;
}
base.OnActionExecuting(filterContext);
}
}
}

Layout = null;
}
