MVC4制作网站教程第二章用户注册2.1

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)

</dd>

<dd>

<div class="label">@Html.LabelFor(model => model.Password)：</div>

<div class="ctrl">@Html.PasswordFor(model => model.Password)

@Html.ValidationMessageFor(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>

</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]

publicActionResultRegister(UserRegisteruserReg)

{

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()!=userReg.VerificationCode.ToUpper())

{

ModelState.AddModelError("VerificationCode","×");

returnView();

}

userRsy=newUserRepository();

if(userRsy.Exists(userReg.UserName))

{

ModelState.AddModelError("UserName","用户名已存在");

returnView();

}

User_user=userReg;

_user.Password=Common.Text.Sha256(userReg.Password);

_user.RegTime=System.DateTime.Now;

if(userRsy.Add(_user))

{

Notice_n=newNotice{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")};

returnRedirectToAction("Notice","Prompt",_n);

}

else

{

Error_e=newError{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<ahref='"+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>"};

returnRedirectToAction("Error","Prompt",_e);

}

}
