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>
