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>
/// 用户登陆模型
/// /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>
/// 密码
/// /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>
[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]
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
@model CMS.Models.UserLogin
@{
ViewBag.Title = "用户登陆";
Layout = "~/Views/Shared/_Layout.cshtml";
}
div class="banner">
img src="~/Skins/Default/Images/banner.jpg" />
/div>
@using (Html.BeginForm())
{
@Html.ValidationSummary(true)
div class="form">
dl>
dt>用户登陆/dt>
dd>
div class="label">@Html.LabelFor(model => model.UserName)：/div>
div class="ctrl">@Html.EditorFor(model => model.UserName)
@Html.ValidationMessageFor(model => model.UserName)
@Html.DisplayDescriptionFor(model => model.UserName)
/div>
/dd>
dd>
div class="label">@Html.LabelFor(model => model.Password)：/div>
div class="ctrl">@Html.PasswordFor(model => model.Password)
@Html.ValidationMessageFor(model => model.Password)
@Html.DisplayDescriptionFor(model => model.Password)
/div>
/dd>
dd>
div class="label">验证码：/div>
div class="ctrl">
@Html.TextBoxFor(model => model.VerificationCode)
@Html.ValidationMessageFor(model => model.VerificationCode)
img id="verificationcode" alt="" src="@Url.Action("VerificationCode", "User")" />
a id="trydifferent" style="cursor: pointer">换一张/a>
/div>
/dd>
dd>
div class="label">/div>
div class="ctrl">
input type="submit" value="登陆" />@Html.ValidationMessage("Message");
/div>
/dd>
/dl>
div class="clear">/div>
/div>
}
script type="text/javascript">
$("#trydifferent").click(function () {
$("#verificationcode").attr("src", "/User/VerificationCode?" + new Date());
})
/script>
@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}
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);
}
