MVC4制作网站好代码教程第二章 用户修改资料2.4

一、用户
1.1用户注册
1.2用户登录
1.3修改密码
1.4修改资料

在用户登陆成功后要跳转到一个页面，暂且叫做用户中心吧。在【UserController】添加[default] action

[UserAuthorize]
 public ActionResult Default()
 {
  userRsy = new UserRepository();
  var _user = userRsy.Find(UserName);
  return View(_user);
 } 

添加相应对应强类型视图

@model Ninesky.Models.User
@{
 ViewBag.Title = "首页";
 Layout = "~/Views/Layout/_User.cshtml";
}

<div class="leftnav">这里左侧导航列表</div>
<div class="workspace">
 <div class ="Nav">您现在的位置： 用户首页</div>
 <div>@Model.UserName
 <br />
 @Model.GroupId
 </div>
</div> 

现在要把左侧导航列表做出来，在视图的User文件夹上点右键新建局部视图PartialPersonalNav

<ul>
 <li>@Html.ActionLink("用户首页","Default","User")</li>
 <li>@Html.ActionLink("修改信息","ChangeInfo","User")</li>
 <li>@Html.ActionLink("修改密码","ChangePassword","User")</li>
 <li>@Html.ActionLink("退出系统","Logout","User")</li>
</ul> 

将default.cshtml中“这里左侧导航列表”替换为@Html.Partial("PartialPersonalNav")。浏览器中打开，导航列表显示出来了。

现在开始做修改用户资料了。在【UserController】添加[ChangeInfo] action

[UserAuthorize]
 public ActionResult ChangeInfo()
 {
  userRsy = new UserRepository();
  var _user = userRsy.Find(UserName);
  return View(_user);
 } 

添加修改资料的处理 action

[HttpPost]
 [UserAuthorize]
 public ActionResult ChangeInfo(User user)
 {
  userRsy = new UserRepository();
  if(userRsy.Authentication(UserName,Ninesky.Common.Text.Sha256(user.Password))==0)
  {
  var _user = userRsy.Find(UserName);
  _user.Gender = user.Gender;
  _user.Email = user.Email;
  _user.QQ = user.QQ;
  _user.Tel = user.Tel;
  _user.Address = user.Address;
  _user.PostCode = user.PostCode;
  if (userRsy.Update(_user))
  {
   Notice _n = new Notice { Title = "修改资料成功", Details = "您已经成功修改资料！", DwellTime = 5, NavigationName = "用户首页", NavigationUrl = Url.Action("Default", "User") };
   return RedirectToAction("UserNotice", "Prompt", _n);
  }
  else
  {
   Error _e = new Error { Title = "修改资料失败", Details = "在修改用户资料时时，更新的资料未能保存到数据库", Cause = "系统错误", Solution = Server.UrlEncode("<li>返回<a rel="nofollow noopener noreferrer" href='" + Url.Action("ChangeInfo", "User") + "'>修改资料</a>页面，输入正确的信息后重新操作</li><li>联系网站管理员</li>") };
   return RedirectToAction("UserError", "Prompt", _e);
  }
  }
  else
  {
  ModelState.AddModelError("Password","密码错误！");
  return View();
  }
  
  
 } 

aciton上右键添加强类型视图，修改视图里自动生成代码，完成后。如下：

@model Ninesky.Models.User

@{
 ViewBag.Title = "修改个人资料";
 Layout = "~/Views/Layout/_User.cshtml";
}

<div class="leftnav">@Html.Partial("PartialPersonalNav")</div>
<div class="workspace">
 <div class="Nav">您现在的位置： 用户首页</div>
 <div>
 @using (Html.BeginForm())
 {
  @Html.ValidationSummary(true)

  <fieldset>
  <legend>修改资料</legend>
  @Html.HiddenFor(model => model.UserId)
  <ul>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.UserName)
   </div>
   <div class="editor-field">
    @Html.DisplayFor(model => model.UserName)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Password)
   </div>
   <div class="editor-field">
    @Html.Password("Password")
    @Html.ValidationMessageFor(model => model.Password)
    输入正确的密码才能修改资料。
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Gender)
   </div>
   <div class="editor-field">
    @Html.RadioButtonFor(model => model.Gender, 0) 男
   @Html.RadioButtonFor(model => model.Gender, 1) 女
   @Html.RadioButtonFor(model => model.Gender, 2) 保密
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Email)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.Email)
    @Html.ValidationMessageFor(model => model.Email)
    @Html.DisplayDescriptionFor(model => model.Email)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.QQ)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.QQ)
    @Html.ValidationMessageFor(model => model.QQ)
    @Html.DisplayDescriptionFor(model => model.QQ)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Tel)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.Tel)
    @Html.ValidationMessageFor(model => model.Tel)
    @Html.DisplayDescriptionFor(model => model.Tel)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.Address)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.Address)
    @Html.ValidationMessageFor(model => model.Address)
    @Html.DisplayDescriptionFor(model => model.Address)
   </div>
   </li>
   <li>
   <div class="editor-label">
    @Html.LabelFor(model => model.PostCode)
   </div>
   <div class="editor-field">
    @Html.EditorFor(model => model.PostCode)
    @Html.ValidationMessageFor(model => model.PostCode)
    @Html.DisplayDescriptionFor(model => model.PostCode)
   </div>
   </li>
   <li><input type="submit" value="修改" /></li>
  </ul>
  </fieldset>
 }
 </div>
</div>

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

运行一下看

输入资料测试一下。能够正常保存到数据库。

======================================
刚开始学MVC，加之表达能力有限，也没有事先写个大致计划，写的很差、很乱。现在是想到哪里就写哪里，有时候做到后面了，发现前边写的不行又去改前面写的代码。

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
