      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,用户注册功能的实现代码,具有一定的参考价值,感兴趣的小伙伴们可以参考一下

    终于开始做用户部分了,先做注册
    一用户 
    1.1用户注册 
    首先在Models里添加用户注册模型类UserRegister 继承自User,在类中new一下密码字段,并添加重复密码和验证码字段。完成后的代码 

    /// <summary>
     /// 用户注册模型
     /// </summary>
     public class UserRegister : User
     {
     /// <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 new string Password { get; set; }
     /// <summary>
     /// 确认密码
     /// </summary>
     [Display(Name = "确认密码", Description = "再次输入密码。")]
     [Compare("Password", ErrorMessage = "×")]
     [DataType(DataType.Password)]
     public string RePassword { 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; }
     }
    

    打开Controllers,在public ActionResult Register()上点右键添加视图,选强类型视图,模型类选择UserRegister 

    添加完成后转到Register.cshtml编辑视图,删除掉自动生成的内容,手动输入想要的代码,完成后代码如下: 

    @model CMS.Models.UserRegister
    
    @{
     ViewBag.Title = "用户注册";
     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>用户注册</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.Gender):</div>
      <div class="ctrl">@Html.RadioButton("Gender", 0) 男 @Html.RadioButton("Gender", 1) 女 @Html.RadioButton("Gender", 2, true) 保密
       @Html.ValidationMessageFor(model => model)
       @Html.DisplayDescriptionFor(model => model)
      </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">@Html.LabelFor(model => model.RePassword):</div>
      <div class="ctrl">@Html.PasswordFor(model => model.RePassword)
       @Html.ValidationMessageFor(model => model.RePassword)
       @Html.DisplayDescriptionFor(model => model.RePassword)
      </div>
      </dd>
      <dd>
      <div class="label">@Html.LabelFor(model => model.SecurityQuestion):</div>
      <div class="ctrl">@Html.EditorFor(model => model.SecurityQuestion)
       @Html.ValidationMessageFor(model => model.SecurityQuestion)
       @Html.DisplayDescriptionFor(model => model.SecurityQuestion)
      </div>
      </dd>
      <dd>
      <div class="label">@Html.LabelFor(model => model.SecurityAnswer):</div>
      <div class="ctrl">@Html.EditorFor(model => model.SecurityAnswer)
       @Html.ValidationMessageFor(model => model.SecurityAnswer)
       @Html.DisplayDescriptionFor(model => model.SecurityAnswer)
      </div>
      </dd>
      <dd>
      <div class="label">@Html.LabelFor(model => model.Email):</div>
      <div class="ctrl">@Html.EditorFor(model => model.Email)
       @Html.ValidationMessageFor(model => model.Email)
       @Html.DisplayDescriptionFor(model => model.Email)
      </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">注册条款:</div>
      <div class="ctrl">
       @Html.CheckBox("Agreement",new {@class="required"})
       我已阅读并同意注册条款
      </div>
      </dd>
      <dd>
      <div class="label"></div>
      <div class="ctrl">
       <input type="submit" value="注册" />
      </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")
    }
    
    

    下面开始写注册处理的代码。 
    在Controllers,在public ActionResult Register(){return View();}下面添加一个[HttpPost]方式的Register() Action,代码如下: 

    [HttpPost]
     public ActionResult Register(UserRegister userReg)
     {
      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() != userReg.VerificationCode.ToUpper())
      {
      ModelState.AddModelError("VerificationCode", "×");
      return View();
      }
      userRsy = new UserRepository();
      if (userRsy.Exists(userReg.UserName))
      {
      ModelState.AddModelError("UserName", "用户名已存在");
      return View();
      }
      User _user = userReg;
      _user.Password = Common.Text.Sha256(userReg.Password);
      _user.RegTime = System.DateTime.Now;
      if (userRsy.Add(_user))
      {
      Notice _n = new Notice { Title = "注册成功", Details = "您已经成功注册,用户为:" + _user.UserName + " ,请牢记您的密码!", DwellTime = 5, Navigation = Url.Action("Login", "User") };
      return RedirectToAction("Notice", "Prompt", _n);
      }
      else
      {
      Error _e = new Error { Title = "注册失败", Details = "在用户注册时,发生了未知错误", Cause = "系统错误", Solution = "<li>返回<a href='" + Url.Action("Register", "User") + "'>注册</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);
      }
     }
    

    OK,运行一下看看效果 

    输入完数据点注册。OK 看到注册成功的页面了

    看一下数据库中也有相应记录了

    注册功能就完成了。
