一个简单的cookie加session的登陆验证

第一步:需要在webconfig下面的标签加

 
     
   

注意~/Account/Login为你的登陆界面。

第二步编写BaseController,代码如下

 [SupportFilter]
    public class BaseController : Controller
    {
       
        public LogonModel CurrentUser
        {
            get
            {
                if (Session["account"] != null)
                    return Session["account"] as LogonModel;
                return null;
            }
        }

        protected override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (HttpContext.User.Identity.IsAuthenticated && Session["account"] == null)
            {
                var u = new LogonModel { LoginName="admin", Password="123", RememberMe=false };
                Session["account"] = u;
            }
            base.OnActionExecuting(filterContext);
        }

        protected bool IsContainRoleName(string roleName)
        {
            return false;
        }
    }

第三步：BaseController新增一个SupportFilter的过滤器，用来过滤一些没有通过验证的，代码如下：

 public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
            {
                filterContext.HttpContext.Response.Write(" ");
                filterContext.Result = new EmptyResult();
                return;
            }
            else
            {
                //编写通过验证的代码
            }
        }

第四步：编写登陆验证代码

   // GET: Account
        public ActionResult Index()
        {
            return View();
        }
        [HttpPost]
        public ActionResult Index(LogonModel model)
        {
            if (ModelState.IsValid)
            {
                var u = model;
                if (u != null)
                {
                    FormsAuthentication.SetAuthCookie(u.LoginName, false);
                    Session["account"] = u;
                    return RedirectToAction("Index", "Home");
                }
            }
           
                 ModelState.AddModelError("LoginName", "验证失败");
                 return View();
            
            
        }

第五步：登陆页面

@model WebApplication4.Models.LogonModel

@{
    ViewBag.Title = "Index";
    Layout = "~/Views/Shared/_Layout.cshtml";
}

Index

@using (Html.BeginForm())
{
    @Html.AntiForgeryToken()
    
   

       

LogonModel

       

---

        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
       

            @Html.LabelFor(model => model.LoginName, htmlAttributes: new { @class = "control-label col-md-2" })
           

                @Html.EditorFor(model => model.LoginName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.LoginName, "", new { @class = "text-danger" })
           

       

       

            @Html.LabelFor(model => model.Password, htmlAttributes: new { @class = "control-label col-md-2" })
           

                @Html.EditorFor(model => model.Password, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Password, "", new { @class = "text-danger" })
           

       

       

            @Html.LabelFor(model => model.ValidateCode, htmlAttributes: new { @class = "control-label col-md-2" })
           

                @Html.EditorFor(model => model.ValidateCode, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.ValidateCode, "", new { @class = "text-danger" })
           

       

       

            @Html.LabelFor(model => model.RememberMe, htmlAttributes: new { @class = "control-label col-md-2" })
           

               

                    @Html.EditorFor(model => model.RememberMe)
                    @Html.ValidationMessageFor(model => model.RememberMe, "", new { @class = "text-danger" })
               

           

       

       

           

               
           

       

   

}

    @Html.ActionLink("Back to List", "Index")

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

第六步：需要身份验证的Controller继承BaseController

 public class HomeController : BaseController
    {
        public ActionResult Index()
        {
            ViewData["userName"] = base.CurrentUser.LoginName;
            return View();
        }

        public ActionResult About()
        {
            ViewBag.Message = "Your application description page.";

            return View();
        }

        public ActionResult Contact()
        {
            ViewBag.Message = "Your contact page.";

            return View();
        }
    }
