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="ctrl">@Html.EditorFor(model => model.UserName)
                    @Html.ValidationMessageFor(model => model.UserName)

                    @Html.ValidationMessageFor(model => model.RePassword)
                    @Html.DisplayDescriptionFor(model => model.RePassword)
                </div>

                    @Html.DisplayDescriptionFor(model => model.SecurityAnswer)
                </div>

            <dd>
                <div class="label">验证码:</div>

                    <img id="verificationcode" alt="" src="@Url.Action("VerificationCode", "User")" />
                    <a id="trydifferent" style="cursor:pointer">换一张</a>

                    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

用户注册 -

输入完数据点注册。OK 看到注册成功的页面了

注册成功 -

看一下数据库中也有相应记录了

注册功能就完成了
