权限管理系统-用户登录

我们之前做了验证码,登录界面,却没有登录实际的代码,我们这次先把用户登录先完成了,要不权限是讲不下去了

把我们之前的表更新到EF中去

登录在Account控制器,所以我们要添加Account的Model,BLL,DAL

AccountModel我们已经创建好了,下面是DAL和BLL的类


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using App.Models;

namespace App.IDAL
{
    public interface IAccountRepository
    {
        SysUser Login(string username, string pwd);
    }
}


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using App.Models;
using App.IDAL;

namespace App.DAL
{
    public class AccountRepository : IAccountRepository,IDisposable
    {
        public SysUser Login(string username, string pwd)
        {
            using (DBContainer db = new DBContainer())
            {
                SysUser user = db.SysUser.SingleOrDefault(a => a.UserName == username && a.Password == pwd);
               return user;
            }
        }
        public void Dispose()
        { 
            
        }
    }
}


using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using App.Models;

namespace App.IBLL
{
    public interface IAccountBLL
    {
        SysUser Login(string username, string pwd);
    }
}


using System.Linq;
using System.Text;
using App.IBLL;
using App.BLL.Core;
using Microsoft.Practices.Unity;
using App.IDAL;
using App.Models;
using App.Common;
namespace App.BLL
{
    public class AccountBLL:BaseBLL,IAccountBLL
    {
        [Dependency]
        public IAccountRepository accountRepository { get; set; }
        public SysUser Login(string username, string pwd)
        {
            return accountRepository.Login(username, pwd);
         
        }
    }
}

注入到容器

 container.RegisterType<IAccountBLL, AccountBLL>();
            container.RegisterType<IAccountRepository, AccountRepository>();

然后回到Account的控制器上

定义

[Dependency]
        public IAccountBLL accountBLL { get; set; }

在 public JsonResult Login(string UserName, string Password, string Code)

方法下添加代码


  if (Session["Code"] == null)
                return Json(JsonHandler.CreateMessage(0, "请重新刷新验证码"), JsonRequestBehavior.AllowGet);

            if (Session["Code"].ToString().ToLower() != Code.ToLower())
                return Json(JsonHandler.CreateMessage(0, "验证码错误"), JsonRequestBehavior.AllowGet);
            SysUser user = accountBLL.Login(UserName, ValueConvert.MD5(Password));
            if (user == null)
            {
                return Json(JsonHandler.CreateMessage(0, "用户名或密码错误"), JsonRequestBehavior.AllowGet);
            }
            else if (!Convert.ToBoolean(user.State))//被禁用
            {
                return Json(JsonHandler.CreateMessage(0, "账户被系统禁用"), JsonRequestBehavior.AllowGet);
            }

            AccountModel account = new AccountModel();
            account.Id = user.Id;
            account.TrueName = user.TrueName;
            Session["Account"] = account;

            return Json(JsonHandler.CreateMessage(1, ""), JsonRequestBehavior.AllowGet);

其中用到一个加密类处理,这里用的是一个MD5大家可以用自己的加密方式

然而这个类里面包含了其他的一些字符串处理,算是在这里共享给大家。不合适就删掉了

回到前端把alert(1);替换以下代码

 $.post('/Account/Login', { UserName: $("#UserName").val(), Password: $("#Password").val(), Code: $("#ValidateCode").val() },
            function (data) {

                if (data.type == "1") {
                    window.location = "/Home/Index"
                } else {
                    $("#mes").html(data.message);
                }
                $("#Loading").hide();
            }, "json");
            return false;
