创建一个控制器，以下是一个简化后的开头内容：
csharpusing System;using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using Demo.Models;
namespace Demo.Controllers{ public class HomeController : Controller { public HomeController() { }
1、创建一个控制器 如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Demo.Models; //命名空间
namespace Demo.Controllers
{
public class HomeController : Controller
{
//
// GET: /Home/
DL_DemoEntities db = new DL_DemoEntities(); //模型
public ActionResult Index() //首页
{
return View();
}
public ActionResult Demo404() //登陆失败跳转
{
return View();
}
public ActionResult Start_Here() //登陆成功跳转
{
return View();
}
[HttpPost]
public ActionResult Login(string name, string password)
{
name = Request["name"];
password = Request["password"];
if (string .IsNullOrEmpty(name)||string .IsNullOrEmpty(password))
{
return Content("<script>alert(‘账号密码不能为空‘);location.href=‘Demo404‘</script>");
}
else
{
var user = db.User.Where(u => u.admin == name && u.passid == password).SingleOrDefault();
if (user == null)
{
return Content("<script>alert(‘输入有误‘);location.href=‘Demo404‘</script>");
}
else
{
return Content("<script>location.href=‘Start_Here‘</script>");
//登录成功跳转
}
}
}
}
}
2、视图界面
<body style="background:url(Html/images/bg.jpg) no-repeat;"> <form action="/Home/Login" method="post"> <div class="container wrap1" style="height:450px;"> <h2 class="mg-b20 text-center">单木不林后台登录页面</h2> <div class="col-sm-8 col-md-5 center-auto pd-sm-50 pd-xs-20 main_content"> <p class="text-center font16">用户登录</p> <form> <div class="form-group mg-t20"> <i class="icon-user icon_font"></i> <input type="text" class="login_input" id="Email1" name="name" placeholder="请输入用户名" /> </div> <div class="form-group mg-t20"> <i class="icon-lock icon_font"></i> <input type="password" class="login_input" id="Password1" name="password" placeholder="请输入密码" /> </div> <div class="checkbox mg-b25"> <label> <input type="checkbox" />记住我的登录信息 </label> </div> <button type="submit" class="login_btn">登 录</button> </form> </div><!--row end--> </div><!--container end--> </form> </body>
抱歉第一次写博客 感觉有点说不清的感觉....
