一用户
1.1用户注册
1.2用户登陆
首先在Models里添加用户登陆模型类UserLogin,该类只要用用户名,密码和验证码三个字段。

/// <summary>

public class UserLogin
{
/// <summary>
/// 用户名
/// </summary>
[Display(Name = "用户名" , Description = "4-20个字符。" )]
[Required(ErrorMessage = "×" )]
[StringLength(20, MinimumLength = 4, ErrorMessage = "×" )]
public string UserName { get ; set ; }
/// <summary>

/// </summary>
[Display(Name = "密码" , Description = "6-20个字符。" )]
[Required(ErrorMessage = "×" )]
[StringLength(20, MinimumLength = 6, ErrorMessage = "×" )]
[DataType(DataType.Password)]
public string Password { get ; set ; }
/// <summary>
/// 验证码
/// </summary>
[Required(ErrorMessage = "×" )]
[StringLength(6, MinimumLength = 6, ErrorMessage = "×" )]
public string VerificationCode { get ; set ; }
}

在UserController里添加Login action; 代码看如下:

public ActionResult Login()
{
return View();
}
[HttpPost]
public ActionResult Login(UserLogin login)
{
return View();
}

使用Cookie保存登陆账号,密码等信息,修改public ActionResult Login(UserLogin login)。修改完成代码如下:
- [HttpPost]
- public ActionResult Login(UserLogin login)
- {
- //验证验证码
- if (Session["VerificationCode"] == null || Session["VerificationCode"].ToString() == "")
- {
- Error _e = new Error { Title = "验证码不存在", Details = "在用户注册时,服务器端的验证码为空,或向服务器提交的验证码为空", Cause = "<li>你注册时在注册页面停留的时间过久页已经超时</li><li>您绕开客户端验证向服务器提交数据</li>", Solution = "返回<a href='" + Url.Action("Register", "User") + "'>注册</a>页面,刷新后重新注册" };
- return RedirectToAction("Error", "Prompt", _e);
- }
- else if (Session["VerificationCode"].ToString() != login.VerificationCode.ToUpper())
- {
- ModelState.AddModelError("VerificationCode", "×");
- return View();
- }
- //验证账号密码
- userRsy = new UserRepository();
- if (userRsy.Authentication(login.UserName, Common.Text.Sha256(login.Password)) == 0)
- {
- HttpCookie _cookie = new HttpCookie("User");
- _cookie.Values.Add("UserName", login.UserName);
- _cookie.Values.Add("Password", Common.Text.Sha256(login.Password));
- Response.Cookies.Add(_cookie);
- return RedirectToAction("Default","User");
- }
- else
- {
- ModelState.AddModelError("Message", "登陆失败!");
- return View();
- }
- }
在public ActionResult Login() 上右键添加强类型视图
完成后代的Login.cshtml

浏览器中查看一下登陆页面
点下登陆测试一下。OK登陆成功
验证用户是否已经登陆,这块和权限验证一起从AuthorizeAttribute继承个自定义验证类
在项目里添加Extensions文件夹,添加一个类UserAuthorizeAttribute 继承自AuthorizeAttribute,重写AuthorizeCore方法用来实现用户是否已经登陆的验证,权限验证在写权限功能时在补充

using Ninesky.Repository;
namespace System.Web.Mvc
{
/// <summary>
/// 用户权限验证
/// </summary>
public class UserAuthorizeAttribute :AuthorizeAttribute
{
/// <summary>
/// 核心【验证用户是否登陆】
/// </summary>
/// <param name="httpContext"></param>
/// <returns></returns>
protected override bool AuthorizeCore(HttpContextBase httpContext)
{
//检查Cookies["User"]是否存在
if (httpContext.Request.Cookies[ "User" ] == null ) return false ;
//验证用户名密码是否正确
HttpCookie _cookie = httpContext.Request.Cookies[ "User" ];
string _userName = _cookie[ "UserName" ];
string _password = _cookie[ "Password" ];
httpContext.Response.Write( "用户名:" +_userName);
if (_userName == "" || _password == "" ) return false ;
UserRepository _userRsy = new UserRepository();
if (_userRsy.Authentication(_userName, _password) == 0) return true ;
else return false ;
}
}
}

以后只要在需要登陆后才能操作的Action或Controller上加[UserAuthorize]就可实现验证是否已经登录了。
退出功能,在UserController添加Logout Action
- /// <summary>
- /// 退出系统
- /// </summary>
- /// <returns></returns>
- public ActionResult Logout()
- {
- if (Request.Cookies["User"] != null)
- {
- HttpCookie _cookie = Request.Cookies["User"];
- _cookie.Expires = DateTime.Now.AddHours(-1);
- Response.Cookies.Add(_cookie);
- }
- Notice _n = new Notice { Title = "成功退出", Details = "您已经成功退出!", DwellTime = 5, NavigationName="网站首页", NavigationUrl = Url.Action("Index", "Home") };
- return RedirectToAction("Notice", "Prompt", _n);
- }
