      MVC4制作网站教程第二章 用户密码修改2.3
      发布时间:2016-12-21 08:01:44 关键词: MVC4,网站,用户密码修改
      内容简介:这篇文章主要为大家详细介绍了MVC4制作网站教程,用户密码修改功能的实现代码,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

    一用户
    1.1用户注册 
    1.2用户登录 
    1.3修改密码 

    修改密码会用到一个UserChangePassword 模型类,先添加UserChangePassword类 

    /// <summary>
      /// 用户修改密码模型
      /// </summary>
      [NotMapped]
      public class UserChangePassword
      {
        /// <summary>
        /// 原密码
        /// </summary>
        [Display(Name = "原密码")]
        [Required(ErrorMessage = "×")]
        [StringLength(20, MinimumLength = 6, ErrorMessage = "×")]
        [DataType(DataType.Password)]
        public string Password { get; set; }
        /// <summary>
        /// 新密码
        /// </summary>
        [Display(Name = "新密码", Description = "6-20个字符。")]
        [Required(ErrorMessage = "×")]
        [StringLength(20, MinimumLength = 6, ErrorMessage = "×")]
        [DataType(DataType.Password)]
        public string NewPassword { get; set; }
        /// <summary>
        /// 确认密码
        /// </summary>
        [Display(Name = "确认密码", Description = "再次输入密码。")]
        [Compare("NewPassword", ErrorMessage = "×")]
        [DataType(DataType.Password)]
        public string ConfirmPassword { get; set; }
      }

    用到了数据库的更新,先打开UserRepository.cs 修改Update函数

    /// <summary>
        /// 更新用户信息
        /// </summary>
        /// <param name="user"></param>
        /// <returns></returns>
        public override bool Update(User user)
        {
          dbContext.Users.Attach(user);
          dbContext.Entry<User>(user).State = System.Data.EntityState.Modified;
          if (dbContext.SaveChanges() > 0) return true;
          else return false;
        }
    
    

    在修改密码时需要查出用户信息并更新,需要添加Find(string UserName) 函数 

    /// <summary>
        /// 查找用户
        /// </summary>
        /// <param name="UserName">用户名</param>
        /// <returns></returns>
        public User Find(string UserName)
        {
          return dbContext.Users.SingleOrDefault(u => u.UserName == UserName);
        }
    
    

    好了打开UserController,添加ChangePassword Action 

    /// <summary>
        /// 修改密码
        /// </summary>
        /// <returns></returns>
        [UserAuthorize]
        public ActionResult ChangePassword()
        {
          return View();
        }
        [HttpPost]
        [UserAuthorize]
        public ActionResult ChangePassword()
        {
          return View();
        }
    
    

    添加强类型(UserChangePassword)视图,在视图中添加三个文本框,修改后的视图代码 

    @model Ninesky.Models.UserChangePassword
    @{ 
      ViewBag.Title = "修改密码";
      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>修改密码</dt>
          <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">@Html.LabelFor(model => model.NewPassword):</div>
            <div class="ctrl">@Html.PasswordFor(model => model.NewPassword)
              @Html.ValidationMessageFor(model => model.NewPassword)
              @Html.DisplayDescriptionFor(model => model.NewPassword)
            </div>
          </dd>
          <dd>
            <div class="label">@Html.LabelFor(model => model.ConfirmPassword):</div>
            <div class="ctrl">@Html.PasswordFor(model => model.ConfirmPassword)
              @Html.ValidationMessageFor(model => model.ConfirmPassword)
              @Html.DisplayDescriptionFor(model => model.ConfirmPassword)
            </div>
          </dd>
          <dd>
            <div class="label"></div>
            <div class="ctrl">
              <input type="submit" value="修改密码" />@Html.ValidationMessage("Message")
            </div>
          </dd>
        </dl>
        <div class="clear"></div>
      </div>
    }
    @section Scripts {
      @Scripts.Render("~/bundles/jqueryval")
    }
    
    

    修改UserController中[HttpPost]方式的ChangePassword()以实现修改密码,修改完成的代码如下: 

    [HttpPost]
        [UserAuthorize]
        public ActionResult ChangePassword(UserChangePassword userChangePassword)
        {
          userRsy = new UserRepository();
          if (userRsy.Authentication(UserName, Common.Text.Sha256(userChangePassword.Password)) == 0)
          {
            var _user = userRsy.Find(UserName);
            if (_user == null)
            {
              Error _e = new Error { Title = "修改密码失败", Details = "修改密码时,系统查询不到用户信息", Cause = Server.UrlEncode("<li>用户在修改密码界面停留的时间过长,登录信息已失效。</li><li>系统错误。</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("ChangePassword", "User") + "'>修改密码</a>页面,输入正确的信息后重新注册</li><li>联系网站管理员</li>") };
    
              return RedirectToAction("Error", "Prompt", _e);
            }
            _user.Password = Common.Text.Sha256(userChangePassword.NewPassword);
            if (userRsy.Update(_user))
            {
              Notice _n = new Notice { Title = "成功修改密码", Details = "您已经成功修改密码,请牢记您的新密码!", DwellTime = 5, NavigationName = "登陆页面", NavigationUrl = Url.Action("Login", "User") };
              return RedirectToAction("Notice", "Prompt", _n);
            }
            else
            {
              Error _e = new Error { Title = "修改密码失败", Details = "修改密码时,更新数据库失败!", Cause = Server.UrlEncode("<li>系统错误。</li>"), Solution = Server.UrlEncode("<li>返回<a href='" + Url.Action("ChangePassword", "User") + "'>修改密码</a>页面,输入正确的信息后重新注册</li><li>联系网站管理员</li>") };
              return RedirectToAction("Error", "Prompt", _e);
            }
          }
          else
          {
            ModelState.AddModelError("Password", "原密码不正确,请重新输入");
            return View();
          }
          
        }
    
    

    在上面的代码中用到了一个UserName属性,这个是在UserController添加的属性用于返回Cookie中保存的用户名 

    /// <summary>
        /// 获取用户名
        /// </summary>
        public string UserName { 
          get {
            HttpCookie _cookie = Request.Cookies["User"];
            if (_cookie == null) return "";
            else return _cookie["UserName"];
            }
        }
    
    

    好了,浏览器中预览一下

     

    测试一下,OK,大功告成!
