MVC Form验证 登陆和退出Cookies的设定和消除

红色部分为重点

1.webconfig配置

 <system.web>节点下添加
    <authentication mode="Forms">
      <forms loginUrl="~/Account/Login" timeout="2880" name=".userInfo" protection="All" path="/"></forms>
    </authentication>
如果有如下节点则删除

<system.webServer>
<modules>
<remove name="FormsAuthentication" />
</modules>
</system.webServer>

2.<forms loginUrl="~/Account/Login  中的loginUrl的值的~不能省略

        public ActionResult Login(LoginViewModel login)
        {
            //验证账号密码
            AspTaskServiceClient service = new AspTaskServiceClient();  //调用svc服务
            if (service.IsLoginOk(login.UserId, Commen.Sha256(login.Password)))
            {
               
                AspUser user = service.GetUserInfo(login.UserId);
                LoginViewModel userinfo = new LoginViewModel()
                {
                    UserId = login.UserId,
                    Password = login.Password,
                    UserName = user.LoginUserName,
                    AspId = user.AspId,
                    IsAsp = user.IsAspUser ? "1" : "0"
                };

                FormsAuthentication.SetAuthCookie(JsonHelper.ToJsonString(userinfo), false);   //设置cookies
                if (Request.QueryString["ReturnUrl"] != null)
                {
                    if (Request.QueryString["ReturnUrl"].Contains("LogOff"))
                    {

                        return RedirectToAction("../Task/TaskList");
                    }
                    else
                    {
                      return  Redirect(Request.QueryString["ReturnUrl"]);
                    }

                }

                else return RedirectToAction("../Task/TaskList");
            }
            else
            {
                ModelState.AddModelError("", "正しくユーザー　または　パスワードを入力ください。");
                return View(login);
            }

        }

　　

3读取cookies

        protected override bool AuthorizeCore(System.Web.HttpContextBase httpContext)
        {
            if (string.IsNullOrWhiteSpace(HttpContext.Current.User.Identity.Name)) return false;
            LoginViewModel userinfo=JsonHelper.ToObject<LoginViewModel>(HttpContext.Current.User.Identity.Name);

            AspTaskServiceClient service = new AspTaskServiceClient();

            string _userId = userinfo.UserId;
            string _password = userinfo.Password;
            if (_userId == "" || _password == "") return false;
            if (service.IsLoginOk(_userId, Commen.Sha256(_password)))
            {
                return true;
            }
            else
            {
                return false;
            }

        }

　　

附：JsonHelper.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Newtonsoft.Json;

namespace xxx.Serialization.Json
{
    public class JsonHelper
    {
        public static string ToJsonString(object obj)
        {
            return JsonConvert.SerializeObject(obj);
        }

   
        public static T ToObject<T>(string jsonString)
        {
            return JsonConvert.DeserializeObject<T>(jsonString);
        }
    }
}

　　

 sha256.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Security.Cryptography;
using System.Text;
using System.Web;

namespace xxx.Controllers
{
    public class Commen
    {
        public static string Sha256(string plainText)
        {
            SHA256Managed _sha256 = new SHA256Managed();
            byte[] _cipherText = _sha256.ComputeHash(Encoding.Default.GetBytes(plainText));
            return Convert.ToBase64String(_cipherText);
        }
    }
}

　　

4.action的cookie值传入到view的js文件

        public ActionResult TaskList()
        {
            ViewBag.cookies = User.Identity.Name;
            return View();
        }

　　

   view里的js文件

如下

        function getUserInfo() {//获取当前用户
            user = new Object();
            var arrCookie = @Html.Raw(ViewBag.cookies);
            if (arrCookie!=null) {
                user.userId =arrCookie["UserId"];
                user.userName = arrCookie["UserName"]
                user.aspId =arrCookie["AspId"];
                user.isAspUser = arrCookie["IsAsp"]== "1" ? true : false;
            }
        }

　　5.退出登陆

1._LoginPartial.cshtml显示设置   必须添加引用

@using xxxx.Serialization.Json;
@using xxx.Models;

    @if (!string.IsNullOrWhiteSpace(User.Identity.Name))
    {

        using (Html.BeginForm("LogOff", "Account", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
        {
            Html.AntiForgeryToken();

            <ul class="nav navbar-nav navbar-right">
                <li>
                    @Html.ActionLink(JsonHelper.ToObject<LoginViewModel>(User.Identity.Name).UserName + " 様", "", "", routeValues: null, htmlAttributes: new { title = "" })
                </li>
                <li><a href="javascript:document.getElementById('logoutForm').submit()">ログオフ</a></li>

            </ul>
        }
    }

　　

　　2.退出登陆清除cookies

        public ActionResult LogOff()
        {
  
            FormsAuthentication.SignOut();
         
            return RedirectToAction("Login", "Account");


        }
