【摘要】：對(duì)于高校教師、學(xué)生來說,高校信息門戶系統(tǒng)已不陌生。全國幾乎70%的公立高校都有自己的信息門戶系統(tǒng)。信息門戶系統(tǒng)包括傳統(tǒng)Web門戶、移動(dòng)Web門戶、移動(dòng)APP門戶、微信平臺(tái)門戶。技術(shù)層面涉及系統(tǒng)數(shù)據(jù)整合、統(tǒng)一身份、單點(diǎn)登陸、統(tǒng)一認(rèn)證、數(shù)據(jù)交換等等。隨著信息門戶系統(tǒng)集成的數(shù)據(jù)越來越多,各應(yīng)用系統(tǒng)的不斷更新與變化,以及國家對(duì)信息安全要求不斷提高,如何通過高效、穩(wěn)定、安全的數(shù)據(jù)整合與集成技術(shù)來構(gòu)建穩(wěn)定、高效、安全的信息門戶系統(tǒng)是一個(gè)值得研究的問題。本文完全從技術(shù)角度針對(duì)數(shù)據(jù)整合與信息集成兩大方面進(jìn)行研究和實(shí)驗(yàn),而不是功能和展現(xiàn)形式。通過對(duì)部分重點(diǎn)高校和普通高�，F(xiàn)有信息門戶系統(tǒng)現(xiàn)狀進(jìn)行調(diào)研,提出了一個(gè)從高校信息化現(xiàn)狀為出發(fā)點(diǎn),基于數(shù)據(jù)緩存與API的無數(shù)據(jù)庫連接支持的信息門戶系統(tǒng)技術(shù)框架。本文研究中產(chǎn)生的創(chuàng)新點(diǎn):(1)在統(tǒng)一身份與用戶數(shù)據(jù)交換方面,采用人員數(shù)據(jù)實(shí)時(shí)同步與手動(dòng)同步相結(jié)合的方式。手動(dòng)同步可以針對(duì)各應(yīng)用系統(tǒng)間人員數(shù)據(jù)無法完全對(duì)應(yīng)、人員數(shù)據(jù)人為的變動(dòng)需延時(shí)操作、人員數(shù)據(jù)誤操作等復(fù)雜情況的解決。(2)基于數(shù)據(jù)緩存技術(shù),建立一個(gè)數(shù)據(jù)中間庫和cache緩存服務(wù),定時(shí)將信息門戶需要的數(shù)據(jù)從各個(gè)業(yè)務(wù)系統(tǒng)中同步或抓取到中間庫中,通過cache技術(shù)將數(shù)據(jù)存放到內(nèi)存中。即使某個(gè)業(yè)務(wù)系統(tǒng)出現(xiàn)故障或宕機(jī),信息門戶仍可訪問該業(yè)務(wù)系統(tǒng)中的數(shù)據(jù)。(3)建立本校的WebAPI數(shù)據(jù)訪問標(biāo)準(zhǔn),采用URL地址格式GET或POST方式進(jìn)行交互。信息門戶系統(tǒng)的所有操作中提交和查看的數(shù)據(jù)信息以及日志信息等全部通過WebAPI方式獲取。(4)信息門戶系統(tǒng)完全脫離數(shù)據(jù)庫連接。信息門戶系統(tǒng)僅需WEB中間件發(fā)布訪問程序,服務(wù)器無需連接任何的數(shù)據(jù)庫。保證數(shù)據(jù)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門戶、手機(jī)APP、微信平臺(tái)門戶中進(jìn)行了實(shí)施,運(yùn)行平穩(wěn),得到了業(yè)界認(rèn)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.
