根据如今信息化快速发展的要求，设计开发了一套基于HTTPS的农业综合知识库系统。系统以MVC 3层框架为技术支撑，结合基于HTTPS协议的单点登录系统，充分利用SSL中的握手原理，在JAVA SCRIPT脚本语言的调用规则基础上，获取包含用户信息的表单后提交到后台，然后后台通过私有公钥解析该表单，并判定用户是否在单点登录系统中成功登录。该系统很好地将耦合度低的多个已有的知识库系统，在不修改代码或修改少量代码的基础上，实现了无缝链接，最终开发出一套农业技术综合知识库系统。

According to the present situation of information technology in enterprises, this paper develops a set of comprehensive agricultural knowledge base system based on HTTPS protocol. Supported by HTTPS protocol and MVC structure, this platform makes a full use of handshake principle of SSL and the calling convention of JAVA SCRIPT language. After submitting the form of user information to the backstage, the private public key analyzes the form and judges whether the user successful logs in the single sign-on system. The seamless link is achieved to connect two or more low coupling systems together without mortifying the code or few codes, and ultimately develop a comprehensive knowledge of agricultural technology system.
