| With the continuous development of Internet facilities and constantly innovation of business model, SaaS (Software as a Service) Service mode has been widely applied in different fields. It provides the solution to the problem of slow informatization process in small and medium-sized enterprises (SEMs) in different industry chains. And also, it brings long-term profits to the application provider. The continuous development of the SaaS mode brings rich software services to the upstream and downstream of industry chain, it also provides more information services for the users who participate in the upstream and downstream business activities.Automobile Industrial Chain Platform includes automobile sales systems, after-sales service systems and all kinds of software applications which related to the entire automobile industry chain. These applications are not isolated applications. Each one can possibly have business relationship with one or more of them, so there is a wide range of data interaction between different applications.To solve the problems of data interaction in this Chain Platform. This thesis used current popular open platform technology to build an open API management system which includes platform operators, application providers and third party developers.Based on the existing services of this industrial Chain Platform, this system solved the problem of API usage and management for the system users. It also brings the possibility to profit from API. In this thesis, the main research content includes the following aspects:(1) Analysis the data interaction technology of Automobile Industrial Chain Platform and discuss its advantages and disadvantages. Discuss the actual requirement of platform operators, application providers and third party developers:to achieve effective API management, to develop and use the API conveniently, to ensure the consistency and security of API data.(2) Based on the requirement analysis, a comprehensive solution to the open API management system was proposed based on Automotive Industrial Chain Platform. And also expounded the application mode and the overall architecture.(3) Through the study of open platform related technology and analysis of the current mainstream open platform architecture. In this thesis, the data simulation was used to realize the API sandbox. And improved Oauth2 standard was used to implement the authentication, authorization and data security of API.(4) Complete the development of open API management system. Implement the data interaction and API management between applications, and verify the feasibility of design scheme. |
