一种能实现文件权限控制的文件上传下载系统

A File Upload and Download System with File Access Authority

对上传下载的目标文件夹创建目录索引,再为索引设置不同的文件操作权限等属性,实现了B/S模式下教师能控制学生上传下载权限的文件上传下载系统。上传下载时,由索引的链接转向来定位目标文件夹位置,借Asp网页Session保存的索引ID来传递操作权限等属性,根据权限属性在文件操作网页上显示不同的文件操作功能,实现了不同索引不同权限的控制。

The system is designed for teachers to control students＇ upload and download authority under B/S structure. A catalogue index is created for the object folder of upload and download, for which different file access authority properties could be set. When uploading or downloading file, object folder could be located via the link of the index, and authority properties could be transferred via the index ID stored in the Asp web session, through which different file operations are provided in the web. Accordingly, the different index controlling different file access authority is achieved.
