【摘要】 本文以上海师范大学校园网上支付平台的设计、开发实现过程为背景撰写而成。上海师范大学的网上支付平台是依托因特网上成熟的第三方支付平台支付宝而构建的校园网络支付平台,该平台的开发目的是让师生通过支付宝平台支付校内各类收费,由于支付宝与国内众多的银行有接口,故上海师范大学的师生在缴费时不再受指定银行的限制。本文的理论部分重点阐述了构建网络支付平台的两个重要技术：PKI及Web Service技术。这两项技术已经是业内成熟的应用技术,通过对PKI技术的分析并对基于PKI技术实现网上支付的设计思想阐述,论述了通过PKI技术构建安全的网络支付平台的方法；通过对Web Service技术的阐述及基于Web Service技术与其他业务系统的集成,论述了通过Web Service接口实现校内业务系统的数据交换功能。本文对上海师范大学网上支付平台进行了需求分析,通过建模工具加文字说明的方式描述了支付平台的需求及核心流程。本文提出了整个系统的总体架构和软件构成,对每个子系统的具体实现方式、性能要求进行了阐述。本文分析了目前网上支付平台接口中普遍采用的MD5签名算法的不足,提出了使用RSA算法改善支付接口签名算法的机制,阐述了使用PKI技术实现网上支付流程、通过支付宝实现校园卡圈存功能及使用Web Service技术实现多个业务系统收费的统一收费接口。根据网上支付平台开发的需求,项目实施过程中经历了集成测试和系统测试阶段,其中系统测试阶段又包括功能测试和性能测试,通过全面的测试,提高软件平台的质量,确保系统的日常正常运行。在完成系统测试交付的基础上,本文对项目的设计与实施进行了总结,阐述了大学校园内通过第三方支付实现校内各类收费的创新意义,打破以往校银合作导致的金融服务局限性,为师生提供了便捷的校园金融服务,为学校管理部门提供统一的财务收费平台,为实现数字化校园的金融服务部分提供了运营管理基础服务平台。更多还原

【Abstract】 The paper is written by the related documents generated in the process of the design and development of the online payment platform, one of the online applications of the campus network of Shanghai Normal University. We set up the platform based on the mature third-party payment platform on the Internet, which is called alipay. The development of this platform is to let the teachers and students to pay school fees through the PayPal platform. Meanwhile they are no longer restricted by designated banks when they pay, because that the alipay has interfaces with numerous domestic banks.The theoretical part of the paper focuses on two important technologies--PKI and Web Service, which are very important in building online payment platform and are already very mature to applications. The method to build the PKI-based security online payment platform is introduced by analyzing the PKI technology and clarifying the design idea; the data exchange function between the campus business systems that is based on the Web Service is put forward by clarifying Web Service technology and its integration with other business systems. Firstly, this paper makes a requirement analysis for Shanghai Normal University’s online payment platform, and describes the requirements and key processes by means of modeling tools and caption. And then, it presents the architecture and software composition of the total system, including the implementation and performance requirements of each subsystem. This paper analyzes the inadequacy of MD5signature algorithm which being commonly used in the current online payment platform interface, it proposes the mechanism for payment interface signature algorithm improved by using the RSA algorithm, and it expounds the realization of online payment process by using PKI technology, the transfer functionality of Campus Card through Alipay and the implementation of the unified charging interface of multiple business system charges by using Web Service. What’s more, the implementation process of the project, according to the development requirements of online payment platform, consists of but not all the integral testing and system testing phases. And the integral testing phase comprises of function testing and performance testing. The software quality is improved and the daily operation is guaranteed by the comprehensive testing.The paper gives a summary of design and implementation of the project on the base of test and delivery of the system, and elaborates innovative significance of charging through the third-party payment platform in the campus. Besides, it summarizes the execution of the online pay platform project.更多还原
