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
GOSET QUOTED_IDENTIFIER ON
GOCREATE 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]

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);

#region 验证码

return View();

然后添加账户管理菜单，无需多说，这个大家懂
接下来是登录功能，首先看看视图Account/Login.cshtml

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！
