(四)学习MVC之修改个人资料和身份验证登陆
1.修改密码不用建立模型，直接在UserControl.cs添加 ChangeInfo():
#region 修改用户资料 [UserAuthorize] public ActionResult ChangeInfo() { userRsy = new UserRepository(); var _user = userRsy.Find(UserName); return View(_user); } [HttpPost] [UserAuthorize] public ActionResult ChangeInfo(User user) { userRsy = new UserRepository(); if (userRsy.Authentication(UserName, ModifyPasswordExample.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 href=http://www.mamicode.com/‘" + 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(); } } #endregion
2.其中[UserAuthorize]特性是[Authorize]的重写，在Extensions/UserAuthorizeAttribute.cs。使用方式是直接在方法上面加这个特性就可以了。
重写后[UserAuthorize]的作用是用户权限认证，比如说直接在浏览器直接输入修改资料的Url，但是由于没有进行身份验证，需要先转到某个指定的页面，身份验证成功后自动回到修改资料的页面，在转到某个指定页面时，会将指定页面之前的Url一起传递过去，这样成功验证后就可以通过传递的Url到达指定页面前的页面。[UserAuthorize]配合的语句一般有这一句：Request.QueryString["ReturnUrl"] != null) return Redirect(Request.QueryString["ReturnUrl"]
using ModifyPasswordExample.Repository;namespace System.Web.Mvc{ /// <summary> /// 用户权限验证 /// </summary> public class UserAuthorizeAttribute :AuthorizeAttribute { /// <summary> /// 核心【验证用户是否登陆】 /// </summary> /// <param name="httpContext"></param> /// <returns></returns> protected override bool AuthorizeCore(HttpContextBase httpContext) { //检查Cookies["User"]是否存在 if (httpContext.Request.Cookies["User"] == null) return false; //验证用户名密码是否正确 HttpCookie _cookie = httpContext.Request.Cookies["User"]; string _userName = _cookie["UserName"]; string _password = _cookie["Password"]; if (_userName == "" || _password == "") return false; UserRepository _userRsy = new UserRepository(); if (_userRsy.Authentication(_userName, _password) == 0) return true; else return false; } }}
WebConfig配置中的<authentication >标签起到指定某个特定页面的作用。这里的指定页面是/User/Login
<authentication mode="Forms"> <forms loginUrl="~/User/Login" timeout="2880" /> </authentication>
3.之前有使用UserControl的Default方法及相对应的视图，现重新修改，代码如下：
方法：
#region 用户中心默认页面 /// <summary> /// 用户中心默认页面 /// </summary> /// <returns></returns> [UserAuthorize] //有加这个特性的方法将会先转到某个特定页面，这里是登录页面。和WebConfig的<authentication>标签一起使用。 public ActionResult Default() { userRsy = new UserRepository(); var _user = userRsy.Find(UserName); return View(_user); } #endregion
视图：
@model ModifyPasswordExample.Models.User@{ ViewBag.Title = "首页"; Layout = "~/Views/Shared/_User.cshtml";}<div class="leftnav"> <div class="Nav"> @*您现在的位置： 用户首页*@ @Html.Partial("PartialPersonalNav") </div> <div> @Model.UserName <br /> @Model.GroupId </div></div>
Shared/_User.cshtml是一个布局视图:<!DOCTYPE html><html><head> <meta name="viewport" content="width=device-width" /> <title>@ViewBag.Title-用户中心</title> @Styles.Render("~/Content/css") @Styles.Render("~/Content/themes/base/css") @Scripts.Render("~/bundles/modernizr") @Scripts.Render("~/bundles/jquery") @Scripts.Render(" ~/bundles/jqueryui") @Scripts.Render("~/bundles/jqueryval")
</head><body> <div class="header"> <div class="info"></div> <div class="menubar"> <a href=http://www.mamicode.com/"@Context @Url.Action("Default", "User")">用户管理</a><a href=http://www.mamicode.com/"@Url.Action("UserDefault", "Article")">文章管理</a> </div> </div> <div class="wrapper"> @RenderBody() </div> <div class="footer"></div></body><script type="text/javascript"> $(".menubar a").button(); $(document).ready(function () { var _vwheight = $(document).height() - $(".header").height() - $(".footer").height();//可视的工作区域高度 var _lheight = $(".left").height(); var _wheight = $(".workspace").height(); if (_vwheight < _lheight) _vwheight = _lheight; if (_vwheight < _wheight) _vwheight = _vwheight; $(".workspace").height(_vwheight); $(".left").height(_vwheight) }); /*按钮*/</script></html>
4.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")。
5.创建ChangeInfo的强类型视图，视图：
@model ModifyPasswordExample.Models.User@{ ViewBag.Title = "修改个人资料"; Layout = "~/Views/Shared/_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=http://www.mamicode.com/"修改" /></li> </ul> </fieldset> } </div></div>
6.运行程序，修改资料正常运行。
