时间：2020-10-05 21:34:14|栏目：.NET代码|点击：次

一、登录数据库，在数据库中创建表User00，并且插入数据。

表的字段分别为：

Id(编号)、Name(姓名)、Grid(级别)、Score(积分)、Password(密码)、Age(年龄)、Code(邀请码)。（其中编号是自动编号）

部分命令如下：

select * from User00; /*查询User00*/
insert into User00 values('one','优',10000,'123',24); /*插入一行数据*/
update User00 set Grid='优' where Id=001; /*更新已存在数据*/
delete from User00; /*删除表里所有数据*/
alter table User00 rename Code to Code; /*更改字段名*/
update User00 set Code =null; /*删除某一列所有数据*/
alter table User00 add Age number; /* user00中插入一列*/
alter table User00 modify Age varchar2(4); /*更改某字段类型*/
delete from User00 where Score is null; /*删除密码为空的所有行*/

二、新建mvc项目kaohe00，添加一个控制器Home。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Model;
using log4net;
using System.Reflection;
//using Bll;
namespace kaohe00.Models
{
public class HomeController : Controller
{
//
//数据库 数据库的
private static Bll.Test00 test00 = new Bll.Test00("Data Source=YWW;User Id=Test00;Password=Test00;"); //连接数据库
// GET: /Home/
public ActionResult Index() //显示主页的动作方法
{
return View();
}
public JsonResult ShowInfo() //把数据库里的表的数据发送到前台的方法
{
var list = test00.GetList(); //
return Json(new { Rows = list, Total = list.Count }, JsonRequestBehavior.AllowGet);
}
public ActionResult Register() //注册的动作方法
{
return View();
}
}
}

三、为Home的Index添加一个视图，显示主页的信息，将数据库的表User00的数据放到主页视图的表格中。

1、主页视图代码：

@{
ViewBag.Title = "Index";
}
<script src="~/Content/jquery/jquery-1.9.0.min.js"></script>
<script src="~/Content/script/common.js"></script>
<script src="~/Content/ligerui/ligerui.all.js"></script>
<link href="~/Content/ligerui/skins/Aqua/css/ligerui-all.css" rel="stylesheet" />
<head>
<title>我的主页</title>
</head>
<div id="maingrid"></div>
<script type="text/javascript">
$(function () {
$("#maingrid").ligerGrid({
columns: [
{ display: '编号', name: 'Id',heigth:100,width:250 },
{ display: '姓名', name: 'Name', heigth: 100, width: 250 },
{ display: '积分', name: 'Score', heigth: 100, width: 250 },
{ display: '密码', name: 'Password', heigth: 100, width: 250 },
{ display: '级别', name: 'Grid', heigth: 100, width: 250 },
{ display: '邀请码', name: 'Code', heigth: 100, width: 250 }
],
url: "/Home/ShowInfo", //调用显示自己信息的动作方法
});
});
</script>

2、主页视图界面：

四、实现登录功能

1、添加一个Login控制器。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
namespace kaohe00.Controllers
{
public class LoginController : Controller
{
//
// GET: /Login/
//数据库
private static Bll.Test00 test00 = new Bll.Test00("Data Source=YWW;User Id=Test00;Password=Test00;"); //连接数据库
public ActionResult Index()
{
return View();
}
public JsonResult LoginTest(string Id ,string Password) //登录验证动作方法
{
var succ = test00.LoginTest(Id, Password);
return Json(new { Succ = succ });
}
}
}

2.1、为Login的Index添加一个视图

视图代码:

@{
ViewBag.Title = "Index";
}
<script src="~/Content/jquery/jquery-1.9.0.min.js"></script>
<script src="~/Content/script/common.js"></script>
<script src="~/Content/ligerui/ligerui.all.js"></script>
<link href="~/Content/ligerui/skins/Aqua/css/ligerui-all.css" rel="stylesheet" />
<head>
<title>登录</title>
</head>
<div id="login">
<div id="Lform"></div>
</div>
<script type="text/javascript">
$(function () {
$("#Lform").ligerForm({
fields: [
{ display: "编号", name: "Id", newline: false, type: "text", },
{ display: "密码", name: "Password", newline: true, type: "password", }
],
});
$.ligerDialog.open({
target: $("#login"),
title: "登录",
allowClose: false,
buttons: [
{
text: '登录', onclick: function (item, dialog) {
var form = liger.get("Lform");
var data = form.getData();
if(data.Id==""||data.Password=="")
{
alert("用户名或密码不能为空");
return false;
}
$.post("/Login/LoginTest", data, function (result) {
//alert(result.Succ);
if(result.Succ == true) {
window.document.location.href = "/Home/Index";
}
else {
alert("登录失败");
return false;
}
});
}
},
{
text: '注册', onclick: function (item, dialog) {
window.document.location.href = "/Register/Index";
}
},
]
});
});
</script>

2.2、登录视图的界面：

五、实现注册功能

1、添加一个注册控制器Register

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using Model;
using log4net;
using System.Reflection;
namespace kaohe00.Controllers
{
public class RegisterController : Controller
{
//数据库
private static Bll.Test00 test00 = new Bll.Test00("Data Source=YWW;User Id=Test00;Password=Test00;");
//
// GET: /Register/
public ActionResult Index()
{
return View();
}
public JsonResult Register(User00 user00)
{ 
var succ=test00.AddNew(user00)>0?1:0;
return Json(new { Succ = succ }, JsonRequestBehavior.AllowGet);
}
}
}

2.1、为注册控制器Register的index添加一个视图

@{
ViewBag.Title = "Index";
}
<script src="~/Content/jquery/jquery-1.9.0.min.js"></script>
<script src="~/Content/script/common.js"></script>
<script src="~/Content/ligerui/ligerui.all.js"></script>
<link href="~/Content/ligerui/skins/Aqua/css/ligerui-all.css" rel="stylesheet" />
<script src="scripts/jquery.validate.js" type="text/javascript"></script>
<head>
<title>注册页面</title>
</head>
<div id="reform"></div>
<div id="rebutton"><input style="margin-left:100px" type="button" value="注册" onclick="register()"></div>
<script type="text/javascript">
function register() {
// alert("test");
var form = liger.get("reform");
// alert(form.name.getData);
var data = form.getData();
if (data.Name == "" || data.Password == ""||data.Grid == "")
{
alert("请完整填写必填信息");
return false;
}
//alert("test");
$.post("/Register/Register", data,
function (data) {
alert("注册成功");
window.document.location.href = "/Home/Index";
});
}
$(function () {
$("#reform").ligerForm({
inputWidth: 170, labelWidth: 90, space: 40,
fields: [
{ display: "姓名 ", name: "Name", newline: true, type: "text",validate:{required:true}},
{ display: "密码", name: "Password", newline: true, type: "password", type: "text", validate: { required: true } },
{ display: "年龄", name: "Age", newline: true, type: "text" },
{ display: "会员级别", name: "Grid", newline: true, type: "text", type: "text", validate: { required: true } },
{ display: "邀请码", name: "Code", newline: true, type: "text" }
],
});
});
</script>

2.2注册视图的界面

六、为数据库的表建立Model模型实体类，建立一个类文件命名为User00.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Model
{
/// <summary>
/// </summary>
public class User00
{
public int Id { get; set; }
public string Name { get; set; }
public string Grid { get; set; }
public int Score { get; set; }
public string Password { get; set; }
public int Age { get; set; }
public int Code { get; set; }
}
}

七、前文出现的Bll命名空间和类Test00等一些代码是引用了另外的库。

1、目录

2、其中文件Test00的代码：

using Blocks.Data;
using Blocks.Data.CustomType;
using Blocks.Data.DbProviders.Oracle;
using kaohe00.Mappings;
using Model;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace Bll
{
public class Test00
{
/// <summary>
/// 数据库
/// </summary>
private Database oracle = null;
public Test00(string connectionString) 
{
this.oracle = new Database(new OracleDbProvider(connectionString));
this.oracle.Mappings(typeof(User00Mapping).Assembly);
}
public List<User00> GetList() //定义GetList函数，其功能：获得一个类型是User00类的列表相当于数组
{
var list = this.oracle.Select<User00>().ToList();
return list;
}
public int AddNew(User00 user00)
{
return this.oracle.Insert(user00);
}
public bool LoginTest(string Id,string Password) //函数功能：判断前台穿的值是否在数据库中的
{
// var search = this.oracle.Select<User00>();
// var list = search.Where(t => t.Id == int.Parse(Id)) && t.Password == Password; 
var search = this.oracle.Select<User00>().Where(t => t.Id == int.Parse(Id) && t.Password == Password);
var list = search.ToList(); //list相当于数组
if (list.Count > 0) //??!!
{
//var user = list.First();
return true;
}
else
{
return false;
}
}
}
}

3、其中的kaohe00.Mappings文件里的User00Mapping.cs的文件的代码：

using Blocks.Data.Mapping;
using Model;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace kaohe00.Mappings
{
public class User00Mapping : ClassMap<User00>
{
public User00Mapping() 
{
Map(t => t.Id).AutoNumber();
Map(t => t.Name);
}
}
}

八、设置路径： defaults: new { controller = "Login", action = "Index", id = UrlParameter.Optional }，使其先执行Login。

九、查看效果：

1、点击登录后密码错误的情况：
