本章主要讲述Web权限管理系统的项目架构,及开发中需要的基本类和相关的CSS,JS文件。
本系统搭建开发工具为Visual Studio 2012,采用ASP.NET MVC 4.0技术开发。系统的框架图如下所示:
特别说明:系统需要用到的CSS文件在Content目录下,公有的JS文件在Scripts目录下。其下载链接为:http://files.cnblogs.com/files/wlandwl/CSS_JS.zip
系统页面前台展示主要运用EasyUI1.4.3的展示控件及其扩展控件,引用到Content目录。系统后台管理主要通过区域的方式开发,运用区域管理可以模块化的开发系统的功能,有助于中大型系统在后期的开发和维护。

为了生成节点信息的安全和高效,引用了DotNetOpenAuth.Messaging动态链接库,需要下载才可以加入到项目中。

数据库模板类主要是把常用sql语句的增,删,改,查及事务集中起来。便于开发中通过类的实例化调用。
该类位于目录OdbcDbAcess文件夹中。文件名称:SqlHelper.cs。

数据集转换类,主要是为了把得到的数据如DataSet封装成指定的格式数据,用于与前台网页数据作特定的交互。
该类位于OdbcDbAcess文件夹中。文件名称:DataTransfor.cs。

会话管理类是权限管理系统的核心类,它主要是根据登录者的id和密码获取相应信息,同时把登录者可以点击的目录,访问的网页存在session中。供系统自动配置出用户的可访问信息。
该类位于BaseBag文件夹中。文件名称:SessionManage.cs。

页面权限检测控制器主要是每访问一个页面信息时,校验该用户是否具有访问该页面的权限。定义为BaseControl.cs控制器,其他的控制器均继承该控制器。

由于登录到首页后,其他页面均是在生成的iframe标签中展示,这些页面都需要引用一些相同的CSS文件,JS文件,为了网页的统一管理,开发了一个共享页面,作为其他页面的模板页。
模板页位于Views/Shared目录中,文件名称为:_BaseLayout.cshtml。引用它的页面通过 @RenderBody()的方式即可把html代码渲染在网页中。
