ASP.NET MVC4.0+EF+LINQ+bui+网站+角色权限管理系统（6）

快过年了，公司事情忙，好几天没有继续写博客，今天开始写账户模块系统登录，账户管理以及登录日志，

首先新建登录日志数据表：

USE [MVCSystem]
GO

/****** Object:  Table [dbo].[UsersLoginLogs]    Script Date: 01/29/2016 15:28:02 ******/
SET ANSI_NULLS ON
GO

SET QUOTED_IDENTIFIER ON
GO

CREATE TABLE [dbo].[UsersLoginLogs](
    [UsersLoginLogID] [int] IDENTITY(1,1) NOT NULL,
    [UsersID] [int] NULL,
    [LoginAddress] [nvarchar](50) NULL,
    [LoginIP] [nvarchar](50) NULL,
    [LoginTime] [datetime2](7) NULL,
    [LoginInfo] [nvarchar](50) NULL,
 CONSTRAINT [PK_UsersLoginLogs] PRIMARY KEY CLUSTERED
(
    [UsersLoginLogID] ASC
)WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]

GO

然后更改模型：AccountModels.cs

using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity;
using System.Globalization;
using System.Web.Security;

namespace MVCSystem.Web.Models
{

    public class RegisterExternalLoginModel
    {
        [Required]
        [Display(Name = "用户名")]
        public string UserName { get; set; }

        public string ExternalLoginData { get; set; }
    }

    public class LocalPasswordModel
    {
        [Required]
        [DataType(DataType.Password)]
        [Display(Name = "当前密码")]
        public string OldPassword { get; set; }

        [Required]
        [StringLength(, ErrorMessage = "{0} 必须至少包含 {2} 个字符。", MinimumLength = )]
        [DataType(DataType.Password)]
        [Display(Name = "新密码")]
        public string NewPassword { get; set; }

        [DataType(DataType.Password)]
        [Display(Name = "确认新密码")]
        [Compare("NewPassword", ErrorMessage = "新密码和确认密码不匹配。")]
        public string ConfirmPassword { get; set; }
    }

    public class LoginModel
    {
        [Required]
        [Display(Name = "用户名")]
        public string UserName { get; set; }

        [Required]
        [DataType(DataType.Password)]
        [Display(Name = "密码")]
        public string Password { get; set; }
        /// <summary>
        /// 验证码
        /// </summary>
        [Required(ErrorMessage = "请输入验证码")]
        [StringLength(, MinimumLength = , ErrorMessage = "验证码错误")]
        public string ValidateCode { get; set; }

        [Display(Name = "记住我?")]
        public bool RememberMe { get; set; }
    }

    public class RegisterModel
    {
        [Required]
        [Display(Name = "用户名")]
        public string UserName { get; set; }

        [Required]
        [StringLength(, ErrorMessage = "{0} 必须至少包含 {2} 个字符。", MinimumLength = )]
        [DataType(DataType.Password)]
        [Display(Name = "密码")]
        public string Password { get; set; }

        [DataType(DataType.Password)]
        [Display(Name = "确认密码")]
        [Compare("Password", ErrorMessage = "密码和确认密码不匹配。")]
        public string ConfirmPassword { get; set; }
    }

    public class ExternalLogin
    {
        public string Provider { get; set; }
        public string ProviderDisplayName { get; set; }
        public string ProviderUserId { get; set; }
    }
}

创建登录日志模型：M_UsersLoginLogs.cs

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

namespace MVCSystem.Web.Models
{
     [Table("UsersLoginLogs")]
    public class M_UsersLoginLogs
    {
         [Key]
        public int UsersLoginLogID { get; set; }
        public int UsersID { get; set; }
        public string LoginAddress { get; set; }
        public string LoginIP { get; set; }
        public DateTime? LoginTime { get; set; }
        public string LoginInfo { get; set; }

    }
}

同样的，MVCSystemContext.cs加上 public DbSet<M_UsersLoginLogs> DB_UsersLoginLogs { get; set; }这句，然后创建账户管理的控制器

AccountController.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Transactions;
using System.Web;
using System.Web.Mvc;
using System.Web.Security;
using DotNetOpenAuth.AspNet;
using Microsoft.Web.WebPages.OAuth;
using WebMatrix.WebData;
using MVCSystem.Web.Filters;
using MVCSystem.Web.Models;
using MVCSystem.Web.Common;
using System.Drawing;
using System.Drawing.Drawing2D;

namespace MVCSystem.Web.Areas.Admin.Controllers
{
    [Authorize]
    [InitializeSimpleMembership]
    public class AccountController : BaseController
    {
        //
        // GET: /Account/Login

        [AllowAnonymous]
        public ActionResult Login(string returnUrl)
        {
            ViewBag.ReturnUrl = returnUrl;
            return View();
        }

        //
        // POST: /Account/Login

        [HttpPost]
        [AllowAnonymous]
        [ValidateAntiForgeryToken]
        public ActionResult Login(LoginModel model, M_UsersLoginLogs userLogs, string returnUrl)
        {
            if (Session["ValidateImgCode"] != null && string.Equals(Session["ValidateImgCode"].ToString(),
                    model.ValidateCode, StringComparison.OrdinalIgnoreCase))
            {
                if (ModelState.IsValid && WebSecurity.Login(model.UserName, model.Password, persistCookie: model.RememberMe))
                {
                    var usersId = db.DB_UserProfiles.Single(u => u.UserName == model.UserName).UserId;//登录日志
                    userLogs.UsersID = usersId;
                    userLogs.LoginAddress = IpHelper.GetAdrByIp(IpHelper.GetRealIP());
                    userLogs.LoginIP = IpHelper.GetRealIP();
                    userLogs.LoginTime = DateTime.Now;
                    userLogs.LoginInfo = IpHelper.GetBrowerVersion();
                    db.DB_UsersLoginLogs.Add(userLogs);
                    db.SaveChanges();

                    return RedirectToLocal(returnUrl);
                }

                // 如果我们进行到这一步时某个地方出错，则重新显示表单
                ModelState.AddModelError("", "提供的用户名或密码不正确。");
                return View(model);
            }
            else {

                ModelState.AddModelError("", "验证码错误");
                return View(model);
            }
        }

        //
        // POST: /Account/LogOff

        [HttpPost]
        [ValidateAntiForgeryToken]
        public ActionResult LogOff()

            return RedirectToAction("Login", "Account");
        }

              }

以及背景图：链接: http://pan.baidu.com/s/1ge0e4GN 密码: urqv。下载后放到Content/Images/

这里的登录页面需要输入验证码，我们需要添加一个空的视图来临时存放每次生成的验证码图片：

Account/ValidateImg.cshtml

@{
    Layout = null;
}

接着需要创建一个登录日志ip地址获取的帮助类，我们把它放到common这个存放公共类的文件夹中：

IpHelper.cs

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Net;
using System.Text;
using System.Text.RegularExpressions;
using System.Web;

namespace MVCSystem.Web.Common
{
    public class IpHelper
    {
        /// <summary>
        /// 通过IP得到IP所在地省市（Porschev）
        /// </summary>
        /// <param name="ip"></param>
        /// <returns></returns>
        public static string GetAdrByIp(string ip)
        {
            string url = "http://www.cz88.net/ip/?ip=" + ip;
            string regStr = "(?<=<span\\s*id=\\\"cz_addr\\\">).*?(?=</span>)";

            //得到网页源码
            string html = GetHtml(url);
            Regex reg = new Regex(regStr, RegexOptions.None);
            Match ma = reg.Match(html);
            html = ma.Value;
            string[] arr = html.Split(' ');
            return arr[];
        }
        /// <summary>
        /// 获取当前Ip所在地址
        /// </summary>
        /// <returns></returns>
        public static string GetAdrByIp()
        {
            string address = GetAdrByIp(GetRealIP());
            return address == "" ? "中国" : address;
        }

        /// <summary>
        /// 获取HTML源码信息(Porschev)
        /// </summary>
        /// <param name="url">获取地址</param>
        /// <returns>HTML源码</returns>
        public static string GetHtml(string url)
        {
            string str = "";
            try
            {
                Uri uri = new Uri(url);
                WebRequest wr = WebRequest.Create(uri);
                Stream s = wr.GetResponse().GetResponseStream();
                StreamReader sr = new StreamReader(s, Encoding.Default);
                str = sr.ReadToEnd();
            }
            catch (Exception e)
            {
            }
            return str;
        }

        /// <summary>
        /// 获得客户端的IP
        /// </summary>
        /// <returns>当前客户端的IP</returns>
        public static string GetRealIP()
        {
            string strIP = HttpContext.Current.Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

            if (strIP == null || strIP.Length < )
            {
                strIP = HttpContext.Current.Request.UserHostAddress;
            }
            if (strIP == null || strIP.Length < )
            {
                return "0.0.0.0";
            }
            return strIP;
        }
        /// <summary>
        /// 获取浏览器的版本以及名称
        /// </summary>
        /// <returns></returns>
        public static string GetBrowerVersion()
        {
            string browerVersion = string.Empty;
            if (System.Web.HttpContext.Current != null)
            {
                System.Web.HttpBrowserCapabilities browser = System.Web.HttpContext.Current.Request.Browser;
                if (browser != null)
                {
                    browerVersion = browser.Browser + browser.Version;
                }
            }
            return browerVersion;
        }
    }
}

最后大道登录后才能访问页面在各个视图中添加授权标识 [Authorize]

namespace MVCSystem.Web.Areas.Admin.Controllers
{
    [Authorize]
    public class HomeController : BaseController
    {

大功告成，接下来看运行效果：

然后根据之前添加的用户账户

可以登录了，然后查看登录日志数据表，可以看到一条登录日志

登录日志管理，这里就不写了，大家可以动手写下！
