【摘要】 本文首先对远程教育的发展做了一个综合性的阐述。在比较不同时代远程教育技术和方式所存在的各种优缺点的基础上,通过分析系统需求,提出了构建在计算机网络环境下,基于web访问的现代远程教育平台的模型。介绍了贵州省电网电力培训中心远程教育平台的设计方案、开发平台、和软硬件系统的实现技术。系统的开发平台选用Apache+MySQL+PHP技术平台,以Windows 2003 server作为操作系统,以Apache为Web服务器,以MySQL为后台数据库,使用PHP语言进行程序开发,以实现与数据库的连接和前端浏览器的控制。同时基于上述系统架构平台,针对系统中的用户登录注册模块的实现进行了详细的描述,其中主要涉及的是系统安全性方面的技术,这些技术主要包括SQL注入攻击的防范、验证码机制和MD5加密机制。更多还原

【Abstract】 This paper is main about the distance education,which compared its distance education in different time and existing different advantage and disadvantage.It has put forward a proposal for this point,and the web has access to the modern distance education model on this environment of computer network from analyses requirement about system.Introduces the realizes technology of design proposal,develops the platform and software & hardware for Distance Education Terrace in Guizhou Electric Fence Electricity Training Centre.The Apache+MySQL+PHP has been chosen as a representative development terrace of system.It is the operating system with the 2003 servers of Windows,taking Apache as the server of Web,taking MySQL as the backstage database,using the PHP language to carry out procedure development, which,is to implement the conjunction of the database and control of front-end browser.According to the above-mentioned system terrace,user logging in to register the mold piece has been detaily description,which invovle in safe technique, mainly including the precaution of SQL attackstone,verification system and MD5 encryption mechanism.更多还原
