首先要建立一个MyWebApp类：
MyWebApp内容：
using System; using System.Collections.Generic; using System.Linq; using System.Text; using Droplets.Models; using System.Web; namespace Droplets.WebCode { public static class MyWebApp { private const string SessionUser = "CurrentUser";//当前用户 public const string LoginUrl = "/Management/Login";//登录界面 public const string LogoutUrl = "/Management/Logout";//退出登录 public static Admin currentUser { get { if (HttpContext.Current == null) return null; return HttpContext.Current.Session[SessionUser] as Admin; } set { HttpContext.Current.Session[SessionUser] = value; } } public static Admin checkLogin() { var user = currentUser; if (user == null) { HttpContext.Current.Response.Redirect(LoginUrl); } return user; } public static void logout() { HttpContext.Current.Session.Remove(SessionUser); } } }
Login View部分：
@model Droplets.Models.Admin @{ Layout = null; ViewBag.Title = "Login"; } <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta charset="utf-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title> 用户登录 </title> <link href="~/Content/icon.css" rel="stylesheet" /> <link href="~/Content/easyui.css" rel="stylesheet" /> <script src="~/Scripts/jquery-1.8.2.min.js"></script> <script src="~/Scripts/jquery.easyui.min.js"></script> <script src="~/Scripts/easyui-lang-zh_CN.js"></script> <script type="text/javascript"> //if (top.location != window.location) //{ // top.location = window.location; //} function login() { $('#form1').submit(); } function cancel() { $('#form1').reset(); } </script> </head> <body style="font-size:11px;"> <div> <div id="win" class="easyui-dialog" buttons="#dialogButtons" title="用户登录" style="360px;height:240px; text-align:center;"> <form style="padding:10px;" id="form1" method="post" action="LoginPost"> <div style="padding:10px;"> <label>用户名:</label> <input type="text" class="easyui-textbox" name="name" required="true"> </div> <div style="padding:10px;"> <label>密 码:</label> <input type="password" name="password" class="easyui-textbox" required="required"></p> </div> </form> </div> <div style="padding:5px;" id="dialogButtons"> <a href="#" class="easyui-linkbutton" icon="icon-ok" onclick="login()">确定</a> <a href="#" class="easyui-linkbutton" icon="icon-cancel" onclick="cancel()">取消</a> </div> </div> </body> </html>
ManagementController部分：
public class ManagementController : AppController { // // GET: /Management/ Droplets.Models.DropletsEntities db; public ManagementController() { db = new DropletsEntities(); } protected override void Dispose(bool disposing) { if (disposing) { db.Dispose(); } base.Dispose(disposing); } public ActionResult Login() { return View(); } [HttpPost] public ActionResult LoginPost(Admin admin) { var m = db.Admin.FirstOrDefault(t => t.Name == admin.Name && t.PassWord == admin.PassWord); if (m == null) { return View("Login");//如果为NULL怎返回登录页面 } else//否则进入Index页面 { WebCode.MyWebApp.currentUser = m; return Redirect("/Management/Index"); } }
