从零开始编写自己的C#框架(15)——Web层后端登陆功能
对于一个后端管理系统,最重要内容之一的就是登陆页了,无论是安全验证、用户在线记录、相关日志记录、单用户或多用户使用帐号控制等,都是在这个页面进行处理的。
1、在解决方案中创建一个Web项目,并将它设置为启动项
2、添加引用
3、添加WebManage文件夹与Login.aspx文件
4、添加登陆页面HTML代码
1 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="Solution.Web.Managers.WebManage.Login" %> 2 3 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 4 <html xmlns="http://www.w3.org/1999/xhtml"> 5 <head id="Head1" runat="server"> 6 <title>从零开始编写自己的C#框架——后端管理系统</title> 7 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 8 <link rel="stylesheet" href=http://www.mamicode.com/"Css/login.css" /> 9 <script type="text/javascript"> 10 function Random(n) { return (Math.floor(Math.random() * n)); }; 11 12 function AjaxRnd() { return new Date().getTime() + ‘‘ + Random(10000); }; 13 14 function ShowKey() { 15 document.getElementById("img_verifycode").src = http://www.mamicode.com/"Base/Vcode.ashx?a=" + AjaxRnd(); 16 }; 17 </script> 18 </head> 19 <body> 20 <!--CENTER开始--> 21 <div class="login-container"> 22 <form id="form1" runat="server"> 23 <div class="login-header"> 24 <h3> 25 Login</h3> 26 </div> 27 <div id="login-content" class="clearfix"> 28 <div> 29 <label> 30 用户名</label> 31 <div> 32 <asp:TextBox runat="server" ID="txtusername" CssClass="input w92" /> 33 </div> 34 <label> 35 密码</label> 36 <div> 37 <asp:TextBox runat="server" ID="txtpass" CssClass="input w92" TextMode="Password" /> 38 </div> 39 <label> 40 验证码</label> 41 <div> 42 <asp:TextBox runat="server" ID="txtcode" CssClass="input w100 fl" /> 43 <asp:Image ID="img_verifycode" runat="server" onclick="ShowKey();" ToolTip="更换验证码" 44 ImageUrl="Base/Vcode.ashx" /> 45 <div class="fc"></div> 46 </div> 47 </div> 48 <div> 49 <asp:Button ID="BtnLogin" CssClass="btn" runat="server" OnClick="BtnLogin_Click" 50 Text="登陆" /> 51 </div> 52 </div> 53 </form> 54 </div> 55 <!--CENTER结束--> 56 </body> 57 </html>
css样式在本文后面的解决方案中有
浏览一下效果
5、后端管理系统登陆验证流程图
我们根据下面的流程图来编写登陆页代码
6、添加在线列表数据表并修改管事员表相关字段
执行下面SQL语句
1 /****** Object: Table [dbo].[Manager] Script Date: 2014/6/4 22:27:52 ******/ 2 if exists (select * from dbo.sysobjects where id = object_id(N‘[dbo].[Manager]‘) and OBJECTPROPERTY(id, N‘IsUserTable‘)

7、添加后端相关表默认记录
1 --添加部门记录 2 INSERT INTO Branch (Code, Name, Notes, ParentId, Sort, Depth, Manager_Id, Manager_CName) 3 VALUES (‘01‘, ‘XX公司‘, ‘‘, 0, 1, 0, 1, ‘admin‘) 4 GO 5 6 --添加职位记录 7 INSERT INTO Position (Name, Branch_Id, Branch_Code, Branch_Name, PagePower, ControlPower, IsSetBranchPower, SetBranchCode, Manager_Id, Manager_CName) 8 VALUES (‘软件开发工程师‘, 1, ‘01‘, ‘XX公司‘, ‘‘, ‘‘, 1, ‘01‘, 1, ‘admin‘) 9 GO 10 11 --添加管理员 12 INSERT INTO Manager (LoginName, LoginPass, LoginIp, LoginCount, Branch_Id, Branch_Code, Branch_Name, Position_Id, Position_Name, IsWork, IsEnable, CName, EName, Sex, Manager_Id, Manager_CName) 13 VALUES (‘admin‘, ‘c3284d0f94606de1fd2af172aba15bf3‘, ‘127.0.0.1‘, 0, 1, ‘01‘, ‘XX公司‘, ‘1‘, ‘软件开发工程师‘, 1, 1, ‘admin‘, ‘admin‘, ‘男‘, 1, ‘admin‘) 14 GO
