mvc C# JavaScript LigerUI oracle实现用户的注册、登陆验证、登陆
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:
或者
2、输入正确的编号密码,进入主页视图界面
3、点击注册后进入注册视图界面
4、在注册界面输入内容,注册失败和成功的情况:
或者
注册成功后点击确定,进入主页视图界面
可以看到主页视图界面新添加的信息
