ASP.NET MVC5 网站开发实践(二) - 用户部分（3）修改资料、修改密码

浏览数：21 / 时间：2015年06月09日

在上一篇博客中实现了用户的注销和登录，其实代码里落了点东西，就是用户登录要更新最后一次登录时间和登录IP，这次补上。今天做修改资料和修改密码，TryUpdateModel是新用到的东西。

一、用户导航菜单

这个就是侧栏的导航，以后所有控制器中action名都为Menu。目标效果如下：

先UserController添加Menu action。直接返回分布视图。右键添加视图

<div class="panel panel-primary">
    <div class="panel-heading"><h3>我的资料</h3></div>
    <div class="panel-body">
        <ul class="nav nav-pills nav-stacked">
            <li> <a href="@Url.Action("Details")"><span class="glyphicon glyphicon-user"> 修改资料</span></a></li>
            <li> <a href="@Url.Action("ChangePassword")"><span class="glyphicon glyphicon-log-out"> 修改密码</span></a></li>
            <li> <a href="@Url.Action("Logout")"><span class="glyphicon glyphicon-log-out"> 退出登录</span></a></li>
        </ul>
    </div>
</div>

二、显示用户资料

再在User控制器里添加显示用户资料的action Details。以后约定所有显示详细资料的动作名都为Details。在控制器中返回当前用户的资料

/// <summary>
        /// 显示资料
        /// </summary>
        /// <returns></returns>
        public ActionResult Details()
        {
            return View(userService.Find(User.Identity.Name));
        }

右键添加视图

@model Ninesky.Models.User

@{
    ViewBag.Title = "我的资料";
}

<div class="row">
    <div class="col-md-3 col-sm-4">@Html.Action("Menu")</div>
    <div class="col-md-9 col-sm-8">

        <ol class="breadcrumb">
            <li><span class="glyphicon glyphicon-home"><a> 会员中心</a></span></li>
            <li><a> 个人中心</a></li>
            <li>修改资料</li>
        </ol>

        @using (Html.BeginForm("Modify","User"))
        {
            @Html.AntiForgeryToken()

            <div class="form-horizontal">
                <h4>用户资料</h4>
                <hr />
                @Html.ValidationSummary(true)
                @Html.HiddenFor(model => model.UserID)

                <div class="form-group">
                    @Html.LabelFor(model => model.UserName, new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.DisplayFor(model => model.UserName)
                    </div>
                </div>

                <div class="form-group">
                    @Html.LabelFor(model => model.DisplayName, new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.DisplayName)
                        @Html.ValidationMessageFor(model => model.DisplayName)
                    </div>
                </div>

                <div class="form-group">
                    <label class = "control-label col-md-2">用户组</label>
                    <div class="col-md-10">
                       @foreach (var _relation in Model.UserRoleRelations){ <span>@_relation.Role.Name</span><br />}
                    </div>
                </div>

                <div class="form-group">
                    @Html.LabelFor(model => model.Email, new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.Email)
                        @Html.ValidationMessageFor(model => model.Email)
                    </div>
                </div>
                <div class="form-group">
                    <div class="col-md-offset-2 col-md-10">
                        <input type="submit" value="修改" class="btn btn-default" />
                    </div>
                </div>
            </div>
        }
    </div>
</div>
@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

@foreach (var _relation in Model.UserRoleRelations){ <span>@_relation.Role.Name</span><br />} 这里是显示用户组名称，延迟加载。

三、修改用户资料

显示用户资料后点击修改直接向后台提交数据，这里把接受并更新数据库的动作名也是Details。在这个方法里不能直接用User做方法参数，因为我只想跟新显示名和邮箱，我如果设置User类型的参数，如果用户向服务器提交的参数中含有UserName，可能用户名都会改掉，这里使用TryUpdateModel来部分更新模型。

/// <summary>
        /// 修改资料
        /// </summary>
        /// <returns></returns>
        [ValidateAntiForgeryToken]
        [HttpPost]
        public ActionResult Modify()
        {

            var _user = userService.Find(User.Identity.Name);
            if (_user == null) ModelState.AddModelError("", "用户不存在");
            else
            {
                if (TryUpdateModel(_user, new string[] { "DisplayName", "Email" }))
                {
                    if (ModelState.IsValid)
                    {
                        if (userService.Update(_user)) ModelState.AddModelError("", "修改成功！");
                        else ModelState.AddModelError("", "无需要修改的资料");
                    }
                }
                else ModelState.AddModelError("", "更新模型数据失败");
            }
            return View("Details", _user);
        }

代码中的TryUpdateModel(_user, new string[] { "DisplayName", "Email" }) 表示我只想从客户提交的数据中更新DisplayName和Email

四、修改密码

先建立一个视图模型ChangePasswordViewModel

using System.ComponentModel.DataAnnotations;

namespace Ninesky.Web.Areas.Member.Models
{
    /// <summary>
    /// 修改密码视图模型
    /// <remarks>创建：2014.02.19</remarks>
    /// </summary>
    public class ChangePasswordViewModel
    {
        /// <summary>
        /// 原密码
        /// </summary>
        [Required(ErrorMessage = "必填")]
        [Display(Name = "密码")]
        [StringLength(20, MinimumLength = 6, ErrorMessage = "{2}到{1}个字符")]
        [DataType(DataType.Password)]
        public string OriginalPassword { get; set; }

        /// <summary>
        /// 新密码
        /// </summary>
        [Required(ErrorMessage = "必填")]
        [Display(Name = "新密码")]
        [StringLength(20, MinimumLength = 6, ErrorMessage = "{2}到{1}个字符")]
        [DataType(DataType.Password)]
        public string Password { get; set; }

        /// <summary>
        /// 确认密码
        /// </summary>
        [Required(ErrorMessage = "必填")]
        [Compare("Password", ErrorMessage = "两次输入的密码不一致")]
        [Display(Name = "确认密码")]
        [DataType(DataType.Password)]
        public string ConfirmPassword { get; set; }
    }
}

然后在UserController中添加动作public ActionResult ChangePassword() 直接返一个视图。右键添加ChangePasswordViewModel类型的视图

@model Ninesky.Web.Areas.Member.Models.ChangePasswordViewModel

@{
    ViewBag.Title = "修改密码";
}
<div class="row">
    <div class="col-md-3 col-sm-4">@Html.Action("Menu")</div>
    <div class="col-md-9 col-sm-8">
        <ol class="breadcrumb">
            <li><span class="glyphicon glyphicon-home"><a> 会员中心</a></span></li>
            <li><a> 个人中心</a></li>
            <li>修改密码</li>
        </ol>

        @using (Html.BeginForm())
        {
            @Html.AntiForgeryToken()

            <div class="form-horizontal">
                <h4>修改密码</h4>
                <hr />
                @Html.ValidationSummary(true)

                <div class="form-group">
                    @Html.LabelFor(model => model.OriginalPassword, new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.OriginalPassword)
                        @Html.ValidationMessageFor(model => model.OriginalPassword)
                    </div>
                </div>

                <div class="form-group">
                    @Html.LabelFor(model => model.Password, new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.Password)
                        @Html.ValidationMessageFor(model => model.Password)
                    </div>
                </div>

                <div class="form-group">
                    @Html.LabelFor(model => model.ConfirmPassword, new { @class = "control-label col-md-2" })
                    <div class="col-md-10">
                        @Html.EditorFor(model => model.ConfirmPassword)
                        @Html.ValidationMessageFor(model => model.ConfirmPassword)
                    </div>
                </div>

                <div class="form-group">
                    <div class="col-md-offset-2 col-md-10">
                        <input type="submit" value="修改" class="btn btn-default" />
                    </div>
                </div>
            </div>
        }

        @section Scripts {
            @Scripts.Render("~/bundles/jqueryval")
        }

    </div>
</div>

在添加一个接受处理动作，代码也很简单

[ValidateAntiForgeryToken]
        [HttpPost]
        public ActionResult ChangePassword(ChangePasswordViewModel passwordViewModel)
        {
            if(ModelState.IsValid)
            {
                var _user = userService.Find(User.Identity.Name);
                if (_user.Password == Common.Security.Sha256(passwordViewModel.OriginalPassword))
                {
                    _user.Password = Common.Security.Sha256(passwordViewModel.Password);
                    if (userService.Update(_user)) ModelState.AddModelError("", "修改密码成功");
                    else ModelState.AddModelError("", "修改密码失败");
                }
                else ModelState.AddModelError("", "原密码错误");
            }
            return View(passwordViewModel);
        }

五、在首页显示登录、注册链接

在Web的Shared文件件添加LoginPartial.cshtml视图文件，在用户未登录时显示登录和注册链接，登录后显示用户名。

@using Microsoft.AspNet.Identity
@if (Request.IsAuthenticated)
{
    using (Html.BeginForm("Logout", "User", FormMethod.Post, new { id = "logoutForm", @class = "navbar-right" }))
    {
        @Html.AntiForgeryToken()

        <ul class="nav navbar-nav navbar-right">
            <li>
                @Html.ActionLink("你好 " + User.Identity.GetUserName() + "!", "Manage", "Account", routeValues: null, htmlAttributes: new { title = "管理" })
            </li>
            <li><a href="javascript:document.getElementById(‘logoutForm‘).submit()">注销</a></li>
        </ul>
    }
}
else
{
    <ul class="nav navbar-nav navbar-right">
        <li>@Html.ActionLink("注册", "Register", "User", routeValues: new { Area = "Member" }, htmlAttributes: new { id = "registerLink" })</li>
        <li>@Html.ActionLink("登录", "Login", "User", routeValues: new {Area="Member"}, htmlAttributes: new { id = "loginLink" })</li>
    </ul>
}
