<form id="formData">
<div class="loginForm">

<script type="text/javascript">
$(function () {
$('.userId,.passwordStyle').on('keyup', function (e) {
if (e.keyCode == 13) {
$('.loginBtn').trigger('click');
}
});
$('.loginBtn').on('click', function () {
$(".warn").hide();
var pwd = $('.passwordStyle').val();
if (pwd == '') {
$(".warn").show().html('请输入密码');
return false;
}
var data = $("#formData").serialize();
$.post("/login/checkLoginInfo", data, function (ajaxObj) {
//回传内容{status: 1(success)/0(fail),}
if (ajaxObj.status == 0 || status == null) {
$(".warn").show().html('用户名或密码错误！');
} else {
//登陆成功，跳转都制定页面
window.location = '/memberCenter/index';
}
}, "json");
});
});
</script>
</html>

复制代码 代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using System.Text;
namespace bigtree.Controllers
{
using bigtree.Models;
using bigtree.Model;
using bigtree.lib;
using System.Net.Mail;
using System.Text.RegularExpressions;
public class LoginController : Controller
{
public ActionResult Index()
{
return View();
}
/// <summary>
/// 检查登陆
/// </summary>
/// <param name="f"></param>
/// <returns></returns>
[HttpPost]
public ActionResult CheckLoginInfo(FormCollection f)
{
try
{
//post: user , pwd ,remembered
string user = f["user"].Trim();
string pwd = f["pwd"].Trim();
string remembered = f["remembered"].Trim();
JsonResult res = new JsonResult();
if (string.IsNullOrEmpty(user) || string.IsNullOrEmpty(pwd))
{
res.Data = new { status = 0 };
}
//MD5加密后的密码
pwd = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(pwd, "md5").ToLower();
//从数据库读取
Common.WebUser account = MemberInfoService.GetMemberIdForCheck(user, pwd);
if (account == null)
{
res.Data = new { status = 0 };
}
else
{
//{status: 1(success)/0(fail),}
res.Data = new { status = 1 };
//todo：登陆成功，记录登陆用户信息保存登陆状态
FunSession.SetSession(account);
//是否记住登录
if (remembered == "on")
{
HttpCookie cookie = new HttpCookie("LoginInfo", account.Id.ToString());
//3天有效
cookie.Expires.AddDays(3);
Response.Cookies.Add(cookie);
}
else
{
HttpCookie cookie = new HttpCookie(account.Id.ToString(), account.Id.ToString());
//使失效
cookie.Expires.AddYears(-1);
Response.Cookies.Add(cookie);
}
}
return res;
}
catch (Exception ex)
{
throw ex.InnerException;
}
}
}
}
