【摘要】：对于高校教师、学生来说,高校信息门户系统已不陌生。全国几乎70%的公立高校都有自己的信息门户系统。信息门户系统包括传统Web门户、移动Web门户、移动APP门户、微信平台门户。技术层面涉及系统数据整合、统一身份、单点登陆、统一认证、数据交换等等。随着信息门户系统集成的数据越来越多,各应用系统的不断更新与变化,以及国家对信息安全要求不断提高,如何通过高效、稳定、安全的数据整合与集成技术来构建稳定、高效、安全的信息门户系统是一个值得研究的问题。本文完全从技术角度针对数据整合与信息集成两大方面进行研究和实验,而不是功能和展现形式。通过对部分重点高校和普通高校现有信息门户系统现状进行调研,提出了一个从高校信息化现状为出发点,基于数据缓存与API的无数据库连接支持的信息门户系统技术框架。本文研究中产生的创新点:(1)在统一身份与用户数据交换方面,采用人员数据实时同步与手动同步相结合的方式。手动同步可以针对各应用系统间人员数据无法完全对应、人员数据人为的变动需延时操作、人员数据误操作等复杂情况的解决。(2)基于数据缓存技术,建立一个数据中间库和cache缓存服务,定时将信息门户需要的数据从各个业务系统中同步或抓取到中间库中,通过cache技术将数据存放到内存中。即使某个业务系统出现故障或宕机,信息门户仍可访问该业务系统中的数据。(3)建立本校的WebAPI数据访问标准,采用URL地址格式GET或POST方式进行交互。信息门户系统的所有操作中提交和查看的数据信息以及日志信息等全部通过WebAPI方式获取。(4)信息门户系统完全脱离数据库连接。信息门户系统仅需WEB中间件发布访问程序,服务器无需连接任何的数据库。保证数据安全,防止sql注入等方式的入侵。本文的研究成果在某高校信息门户、手机APP、微信平台门户中进行了实施,运行平稳,得到了业界认可。
[Abstract]:For college teachers and students, the university information portal system is no stranger. Almost 70% public colleges and universities in China have their own information portal system. The information portal system includes traditional Web portal, mobile Web portal, mobile APP portal. WeChat platform portal. Technology level involves system data integration, unified identity, single access, unified authentication, data exchange and so on. And the country's requirements for information security continue to improve, how to build stability and efficiency through efficient, stable and secure data integration and integration technology, The secure information portal system is a problem worth studying. This paper makes research and experiments on data integration and information integration from the technical point of view. By investigating the present situation of information portal system in some key colleges and universities, this paper puts forward a starting point from the current situation of information technology in colleges and universities. The technical framework of information portal system without database connection support based on data cache and API. The manual synchronization can not completely correspond to the personnel data among the application systems, and the artificial change of the personnel data needs to delay operation. On the basis of data cache technology, we set up a data intermediate library and cache cache service to synchronize or capture the data needed by the information portal from each business system. The data is stored in memory through cache technology. Even if a business system fails or goes down, the information portal can still access the data in the service system. The data submitted and viewed in all operations of the information portal system, as well as the log information, etc., were obtained by WebAPI. 4) the information portal system completely separated from the database. The information portal system only needs WEB middleware to publish the accessor, The server does not need to connect to any database. It ensures the data security and prevents the intrusion of sql injection. The research results of this paper are implemented in a university information portal, mobile phone app, WeChat platform portal, and run smoothly. Has been recognized by the industry.
