學用MVC4做網站一:用戶注冊1.1

終於開始做用戶部分了，先做注冊

一用戶

1.1用戶注冊

首先在Models里添加用戶注冊模型類UserRegister 繼承自User，在類中new一下密碼字段，並添加重復密碼和驗證碼字段。完成后的代碼

/// <summary>
    /// 用戶注冊模型
    /// </summary>
    public class UserRegister : User
    {
        /// <summary>
        /// 密碼
        /// </summary>
        [Display(Name="密碼",Description="6-20個字符。")]
        [Required(ErrorMessage = "×")]
        [StringLength(20,MinimumLength=6,ErrorMessage = "×")]
        [DataType(DataType.Password)]
        public new string Password { get; set; }
        /// <summary>
        /// 確認密碼
        /// </summary>
        [Display(Name = "確認密碼", Description = "再次輸入密碼。")]
        [Compare("Password", ErrorMessage = "×")]
        [DataType(DataType.Password)]
        public string RePassword { get; set; }
        /// <summary>
        /// 驗證碼
        /// </summary>
        [Display(Name = "驗證碼", Description = "請輸入圖片中的驗證碼。")]
        [Required(ErrorMessage = "×")]
        [StringLength(6,MinimumLength=6,ErrorMessage = "×")]
        public string VerificationCode { get; set; }
    }

打開Controllers，在public ActionResult Register()上點右鍵添加視圖，選強類型視圖，模型類選擇UserRegister

添加完成后轉到Register.cshtml編輯視圖，刪除掉自動生成的內容，手動輸入想要的代碼，完成后代碼如下：

@model CMS.Models.UserRegister

@{
    ViewBag.Title = "用戶注冊";
    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>用戶注冊</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)

            <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">驗證碼：</div>
                <div class="ctrl">

                    <img id="verificationcode" alt="" src="@Url.Action("VerificationCode", "User")" />
                    <a id="trydifferent" style="cursor:pointer">換一張</a>

            </dd>
            <dd>
                <div class="label">注冊條款：</div>
                <div class="ctrl">
                    @Html.CheckBox("Agreement",new {@class="required"})
                    我已閱讀並同意注冊條款
                </div>
            </dd>
            <dd>
                <div class="label"></div>
                <div class="ctrl">
                    <input type="submit" value="注冊" />
                </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")
}

下面開始寫注冊處理的代碼。

在Controllers，在public ActionResult Register(){return View();}下面添加一個[HttpPost]方式的Register() Action，代碼如下：

[HttpPost]
        public ActionResult Register(UserRegister userReg)
        {
            if (Session["VerificationCode"] == null || Session["VerificationCode"].ToString() == "")
            {
                Error _e = new Error { Title = "驗證碼不存在", Details = "在用戶注冊時，服務器端的驗證碼為空，或向服務器提交的驗證碼為空", Cause = "<li>你注冊時在注冊頁面停留的時間過久頁已經超時</li><li>您繞開客戶端驗證向服務器提交數據</li>", Solution = "返回<a href='" + Url.Action("Register", "User") + "'>注冊</a>頁面，刷新后重新注冊" };
                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", "用戶名已存在");
                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 = "注冊成功", Details = "您已經成功注冊，用戶為：" + _user.UserName + " ，請牢記您的密碼！", DwellTime = 5, Navigation = Url.Action("Login", "User") };
                return RedirectToAction("Notice", "Prompt", _n);
            }
            else
            {
                Error _e = new Error { Title = "注冊失敗", Details = "在用戶注冊時，發生了未知錯誤", Cause = "系統錯誤", Solution = "<li>返回<a href='" + Url.Action("Register", "User") + "'>注冊</a>頁面，輸入正確的信息后重新注冊</li><li>聯系網站管理員</li>" };
                return RedirectToAction("Error", "Prompt", _e);
            }
        }

OK，運行一下看看效果

輸入完數據點注冊。OK 看到注冊成功的頁面了

看一下數據庫中也有相應記錄了

注冊功能就完成了
