基于Web系统的文件传输方法研究

Research on File Transmission Based on Web

传统的基于Web的文件传输方法存在弊病。在Web页面中设置隐形变量的方法只能用于小数据量的文件传输,遇到数据量较大的情况,用户打开网页的时间会很长;在Web页面中嵌入被传文件的链接URL的方法不能控制文件的访问权限,而且容易泄露FTP服务器的用户名和密码。本文介绍了一种基于Web的文件传输方法:在客户端利用文件传输控件(ActiveX控件或Java Applet控件)解析响应页面,并向文档服务器发出FTP文件传输请求。这种方法克服了现有Web系统中文件传输技术的不足,提供了一种能够有效提高Web系统中文件传输效率和安全性的方法。

Traditional methods of file transmission based on Web have quite a few drawbacks. Hiding variables in Web pages can be used to transmit little data. Once encountered large data, people will spend a lot of time to open Web pages; Method of embedding URL of file can not control the access power, at same time, this method may disclose the user name and password of FTP server. There is a good method that uses ActiveX or Java Applet to analyse Web pages and send FTP file transmission request to file server. This method can overcome it＇s shortcoming of file transmission based on Web. At the same time, this method gives a solution of raising efficiency and security in file transmission fields based on Web.
