1、登录页面代码:
@{ ViewBag.Title = "会员登录"; Layout = "~/Views/Shared/_LayoutDialog.cshtml"; } <div class="loginBox"> <div class="loginHead" > 会员登录 </div> <form id="hgl-form" class="form-horizontal" action="@Url.Action("Login", "Home", new { area = string.Empty })" method="post"> <div class="control-group"> <label for="inputEmail">账户</label> <input type="text" name="account" id="inputEmail" class="validate[required]" /> </div> <div class="control-group"> <label for="inputPassword">密码</label> <input type="password" name="password" id="inputPassword" class="validate[required]" /> </div> @*<div class="control-group" > <label class="checkbox"> <input type="checkbox" name="rememberMe" checked> 记住我</label> </div>*@ <div class="form-actions"> <button type="submit" class="btn btn-block">登录</button> </div> </form> </div> @section scripts{ <script type="text/javascript"> $(function () { //表单提交 hgl.sumbit(function () { location.href = ‘@Url.Action("Index", "SiteSet", new { area = "Setting" })‘;//登陆成功后跳转到的页面 }); }) </script>}
2、登录controller代码:
//会员登录 [HttpGet] public ActionResult Login() { return View(); } [HttpPost] public ActionResult Login(string account, string password) { var entity = AdminService.QueryDetailForAccount(account); if (entity == null) return JRFaild("all", "此账户不存在"); if (entity.Password != password.ToMD5()) return JRFaild("all", "账户密码输入错误,请重新输入"); if (entity.Freezed == 1) return JRFaild("all", "此账户已被冻结,暂不能登录,请联系超级管理员"); var result = AdminService.Login(account, password, entity); if (result) { Session["account"] = account; Session["guid"] = entity.Guid; Session["username"] = entity.Name; Session["password"] = password; return JRSuccess("登录成功"); } return JRFaild("all", "登录失败,用户名或密码错误或账户不存在"); }
前面是登录模块的代码;下面主要介绍 ActionFilterAttribute过滤器的使用
1、在项目中新建个Filter文件夹,在文件夹里面添加该过滤器类,命名为:BasicAuthAttribute.cs;此类需要继承ActionFilterAttribute(关于ActionFilterAttribute大家可以按F12跳转到该类的详细介绍进行了解和使用);我在新建的BasicAuthAttribute.cs中使用了OnActionExecuting,该类代码如下:如下代码在使用的时候还需要添加引用:
using System.Web.Mvc; using System.Web.Routing; using System.Web.Security;
namespace Linkin.Manager.Filter { public class BasicAuthAttribute : ActionFilterAttribute { public override void OnActionExecuting(ActionExecutingContext filterContext) { var account = filterContext.HttpContext.Session["account"]; var password = filterContext.HttpContext.Session["password"]; if (account == null || password == null) { //用户不登陆的时候跳转到登录页面 filterContext.Result = new RedirectToRouteResult(new RouteValueDictionary(new { controller = "Home", action = "Login", area = string.Empty })); } } } }
到此为止,过滤器已经写好了,具体的项可以直接F12到起定义进行查看,可以看出当用户不登陆的时候会跳转到登录页面
2、此时需要到配置文件里的登录配置是怎么配置的,打开web.config,找到节点<authentication mode="Forms"></authentication>查看配置,如果自己的登录页面跟web.config里面的配置一样就不需要修改了,不一致的最好修改一下
<!--这里配置的是登录页面的权限配置--> <authentication mode="Forms"> <forms loginUrl="~/Home/Login" timeout="2880" /> </authentication>
3、这样以后在controller里面就可以直接用该过滤器了,在要使用此项过滤器的controller里面直接加入下面的红色字体,此时这样还需要引入该文件的引用:using Linkin.Manager.Filter;(此引用要根据自己的项目的实际情况来添加)代码如下:
[BasicAuthAttribute] public class AdminController : BasicController { [HttpGet] public ActionResult Index(string id, string key, int state = -1, int page = 1) { ViewBag.Id = id; ViewBag.Key = key; ViewBag.State = state; return View(AdminService.QueryPageList(id, key, state, page, 10)); } }
上面的代码是将起放到了外面,也可以将起直接放到里面,如下:
public class AdminController : BasicController { [BasicAuthAttribute] [HttpGet] public ActionResult Index(string id, string key, int state = -1, int page = 1) { ViewBag.Id = id; ViewBag.Key = key; ViewBag.State = state; return View(AdminService.QueryPageList(id, key, state, page, 10)); } }
4、经过以上的步骤就弄好了,此时运行网站,在不登陆的时候,直接在浏览器的地址栏输入http://localhost:2341/setting/admin,此时可以看到页面跳转到了登录页面
