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

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

public string Password { get; set; }

[Display(Name = "验证码", Description = "请输入图片中的验证码。")]
[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]
- publicActionResultLogin(UserLoginlogin)
- {
- //验证验证码
- if(Session["VerificationCode"]==null||Session["VerificationCode"].ToString()=="")
- {
- Error_e=newError{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<ahref='"+Url.Action("Register","User")+"'>注册</a>页面，刷新后重新注册"};
- returnRedirectToAction("Error","Prompt",_e);
- }
- elseif(Session["VerificationCode"].ToString()!=login.VerificationCode.ToUpper())
- {
- ModelState.AddModelError("VerificationCode","×");
- returnView();
- }
- //验证账号密码
- userRsy=newUserRepository();
- if(userRsy.Authentication(login.UserName,Common.Text.Sha256(login.Password))==0)
- {
- HttpCookie_cookie=newHttpCookie("User");
- _cookie.Values.Add("UserName",login.UserName);
- _cookie.Values.Add("Password",Common.Text.Sha256(login.Password));
- Response.Cookies.Add(_cookie);
- returnRedirectToAction("Default","User");
- }
- else
- {
- ModelState.AddModelError("Message","登陆失败！");
- returnView();
- }
- }
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>
- publicActionResultLogout()
- {
- if(Request.Cookies["User"]!=null)
- {
- HttpCookie_cookie=Request.Cookies["User"];
- _cookie.Expires=DateTime.Now.AddHours(-1);
- Response.Cookies.Add(_cookie);
- }
- Notice_n=newNotice{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")};
- returnRedirectToAction("Notice","Prompt",_n);
- }
