Asp.Net MVC+BootStrap+EF6.0实现简单的用户角色权限管理4

 首先先加个区域，名为Admin

using System.Web.Mvc;

namespace AuthorDesign.Web.Areas.Admin {
    public class AdminAreaRegistration : AreaRegistration {
        public override string AreaName {
            get {
                return "Admin";
            }
        }

        public override void RegisterArea(AreaRegistrationContext context) {
            context.MapRoute(
                "Admin_default",
                "Admin/{controller}/{action}/{id}",
                new { action = "Index", id = UrlParameter.Optional }
            );
        }
    }
}

更改下区域里面里的路由配置代码为：

using System.Web.Mvc;

namespace AuthorDesign.Web.Areas.Admin {
    public class AdminAreaRegistration : AreaRegistration {
        public override string AreaName {
            get {
                return "Admin";
            }
        }

        public override void RegisterArea(AreaRegistrationContext context) {
            context.MapRoute(
                "Admin_default",
                "Admin/{controller}/{action}/{id}",
                new { controller= "Home", action = "Index", id = UrlParameter.Optional },
                new string[] { "AuthorDesign.Web.Areas.Admin.Controllers" }
            );
        }
    }
}

然后再区域下的Controllers文件下添加一个名为Account的控制器

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;

namespace AuthorDesign.Web.Areas.Admin.Controllers
{
    public class AccountController : Controller
    {
        //
        // GET: /Admin/Account/

        public ActionResult Index()
        {
            return View();
        }

    }
}

将Index改为Login

然后我再添加Login的视图。点击添加之后就会在对应的Views。

页面模板就是找bootstrap的模板了。http://pan.baidu.com/s/1mgs7hWG这里是分享的模板链接。

首先是登录页面的html代码

<!DOCTYPE html>

        }
    </script>
</body>
</html>

效果如下

验证码的代码如下：

#region 验证码
        /// <summary>
        /// 功能：返回验证码图片
        /// </summary>
        /// <returns></returns>
        public ActionResult ValidateImg() {
            Color color1 = new Color();
            //---------产生随机6位字符串
            Random ran = new Random();
            char[] c = new char[62];
            char[] ou = new char[6];
            int n = 0;
            for (int i = 65; i < 91; i++) {
                c[n] = (char)i;
                n++;
            }
            for (int j = 97; j < 123; j++) {
                c[n] = (char)j;
                n++;
            }
            for (int k = 48; k < 58; k++) {
                c[n] = (char)k;
                n++;
            }
            foreach (char ch in c) {
                Console.WriteLine(ch);
            }
            string outcode = "";
            for (int h = 0; h < 6; h++) {
                ou[h] = c[ran.Next(62)];
                outcode += ou[h].ToString();
            }
            //
            Session["ValidateImgCode"] = outcode;

            //1.创建一个新的图片，大小为(输入的字符串的长度*12),22
            System.Drawing.Bitmap bmap = new System.Drawing.Bitmap(outcode.Length * 18, 25);

            //2.定义画图面板，基于创建的新图片来创建
            System.Drawing.Graphics g = System.Drawing.Graphics.FromImage(bmap);

            //3.由于默认的画图面板背景是黑色，所有使用clear方法把背景清除，同时把背景颜色设置为白色
            g.Clear(System.Drawing.Color.White);

            // 画图片的背景噪音线
            for (int i = 0; i < 25; i++) {
                int x1 = ran.Next(bmap.Width);
                int x2 = ran.Next(bmap.Width);
                int y1 = ran.Next(bmap.Height);
                int y2 = ran.Next(bmap.Height);
                g.DrawLine(new Pen(color1), x1, y1, x2, y2);
            }

            // 画图片的前景噪音线
            for (int i = 0; i < 100; i++) {
                int x = ran.Next(bmap.Width);
                int y = ran.Next(bmap.Height);
                bmap.SetPixel(x, y, Color.FromArgb(ran.Next()));
            }

            //4.使用DrawString 方法把要输出的字符串输出到画板上。输出的字符从参数(outcode)内获得。
            Font font = new Font("Arial", 14, FontStyle.Bold | FontStyle.Italic);
            LinearGradientBrush brush = new LinearGradientBrush(new Rectangle(0, 0, bmap.Width, bmap.Height), Color.Blue, Color.DarkRed, 1.2f, true);
            g.DrawString(outcode, font, brush, 0, 0);

            //5.定义一个内存流，把新创建的图片保存到内存流内，这样就不用保存到磁盘上，提高了速度。
            System.IO.MemoryStream ms = new System.IO.MemoryStream();

            //6.把新创建的图片保存到内存流中，格式为jpeg的类型
            bmap.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);

            //7.输出这张图片，由于此页面的 ContentType="image/jpeg" 所以会输出图片到客户端。同时输出是以字节输出，所以要把内存流转换为字节序列，使用ToArray()方法。
            Response.BinaryWrite(ms.ToArray());
            return View();
        }
        #endregion

注意验证码要建个个分布视图用来输出图片用的。

然后再Model文件夹下建立LoginModel

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Web;

namespace AuthorDesign.Web.Areas.Admin.Models {
    /// <summary>
    /// 登录类
    /// </summary>
    public class LoginModel {
        /// <summary>
        /// 用户名
        /// </summary>
        [Required(ErrorMessage="请输入用户名")]
        [StringLength(30,MinimumLength=5,ErrorMessage="请输入正确的用户名")]
        public string UserName { get; set; }
        /// <summary>
        /// 密码
        /// </summary>
        [Required(ErrorMessage = "请输入用密码")]
        [StringLength(30, MinimumLength = 5, ErrorMessage = "请输入正确的密码")]
        public string Password { get; set; }
        /// <summary>
        /// 验证码
        /// </summary>
        [Required(ErrorMessage="请输入验证码")]
        [StringLength(6,MinimumLength=6,ErrorMessage="验证码错误")]
        public string ValidateCode { get; set; }
        /// <summary>
        /// 是否记住密码
        /// </summary>
        public bool IsRemind { get; set; }
    }
}

然后更改登录页面的Html代码

            }
        })
    </script>

</body>
</html>

 

然后再建立一个类，这个类是专门用来与数据层进行交互的。

using AuthorDesign.DAL;
using AuthorDesign.IDAL;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Remoting.Messaging;
using System.Web;

namespace AuthorDesign.Web.App_Start.Common {
    public class EnterRepository {
        /// <summary>
        /// 获取DAL入口类
        /// </summary>
        /// <returns></returns>
        public static IRepositoryEnter GetRepositoryEnter() {
            IRepositoryEnter _enter = CallContext.GetData("CurrentRepositoryEnter") as RepositoryEnter;
            if (_enter == null) {
                _enter = new RepositoryEnter();
                CallContext.SetData("CurrentRepositoryEnter", _enter);
            }
            return _enter;
        }
    }
}

在后台添加登录的方法：

在写方法的时候我发现Admin这个类少了个是否可登录这字段，那么就先去加上这个字段

/// <summary>
/// 是否可登录
/// </summary>
public Byte IsLogin { get; set; }

然后在这个类中添加如下代码：

        protected override void Seed(AuthorDesign.DAL.AuthorDesignContext context)
        {
            //  This method will be called after migrating to the latest version.

            //  You can use the DbSet<T>.AddOrUpdate() helper extension method 
            //  to avoid creating duplicate seed data. E.g.
            //
            context.Admins.AddOrUpdate(
                  p => p.AdminName,
                  new Admin() { AdminName = "admin", CreateTime = DateTime.Now, IsLogin = 1, Salt = "1234567890", Password = "42C224B3C8899047460F5A6D1C041411", LastLoginAddress = "大中国", LastLoginIp = "192.168.254.23", LastLoginTime = DateTime.Now, IsSuperAdmin = 1 }
            );
            //
        }

这个的作用就是像数据库中加入一条数据，我这条加入的数据是一个用户名为admin 密码为123456的数据

然后执行控制台指令 add-migration AddAdminIsLogin  执行完成之后再执行 update-database 数据库就更新了，然后admin的这条默认数据也加进去了。

然我在写这个方法的是去DAL中把原先的增删改的方法修改了下，

                temp = temp.OrderBy<T, S>(orderLamda).Skip<T>(pageSize * (pageIndex - 1) + 1).Take<T>(pageSize);
            return temp;
        }
    }
}

我把savechange的方法都注释掉了，因为我把这方法都放到web层来操作了。在ef中增删改方法只有在调用savechange方法之后他才会和数据库进行交互的。把savechange方法提出来有利于控制。

然后再Account控制器下面添加一个登录的方法。

        [HttpPost]
        public JsonResult Login(Models.LoginModel model) {
            if (ModelState.IsValid) {
                //首先判断下验证码是否正确
                if (Session["ValidateImgCode"] != null && string.Equals(Session["ValidateImgCode"].ToString(),
                    model.ValidateCode, StringComparison.OrdinalIgnoreCase)) {
                    Model.Admin adminModel = new Model.Admin();
                    if (new Regex("1[3|5|7|8|][0-9]{9}").IsMatch(model.UserName)) {//匹配手机号码
                        adminModel = EnterRepository.GetRepositoryEnter().GetAdminRepository.LoadEntities(m => m.Mobile == model.UserName && m.IsLogin == 1).FirstOrDefault();
                    }
                    else if (new Regex(@"[A-Za-z0-9.%+-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}").IsMatch(model.UserName)) {//匹配邮箱
                        adminModel = EnterRepository.GetRepositoryEnter().GetAdminRepository.LoadEntities(m => m.Email == model.UserName && m.IsLogin == 1).FirstOrDefault();
                    }
                    else {//匹配用户名
                        adminModel = EnterRepository.GetRepositoryEnter().GetAdminRepository.LoadEntities(m => m.AdminName == model.UserName&&m.IsLogin==1).FirstOrDefault();
                    }
                    if (adminModel == null) {
                        return Json(new {

                        //判断密码是否正确
                        if (adminModel.Password == MD5Helper.CreatePasswordMd5(model.Password, adminModel.Salt)) {
                            adminModel.LastLoginTime = DateTime.Now;
                            adminModel.LastLoginIp = IpHelper.GetRealIP();
                            adminModel.LastLoginAddress = IpHelper.GetAdrByIp(adminModel.LastLoginIp);
                            adminModel.LastLoginInfo = IpHelper.GetBrowerVersion();
                            //添加登录日志并修改上次登录信息

这里在登录的时候使用了cookie来存储信息，和加入了一条用户登录日志。对于cookie的存储，我会放源码到百度云分享去的，昨天看了下github好像出了点问题。

获取用户的登录Ip和浏览器信息的之类的都是在网上查到的，根据ip获取地址的这个也是在网上查找的。

然后就可以去登录了。调试结果如下

好了登录页面就这样了。可能中间讲的很乱。有疑问的或者有觉得不好的请指出来哈。
