| With the rapid development of Web services, users and applications continue to grow, the number of open API also appeared a lot of growth and the number of open API with the same or similar function is also increasing. And with the proliferation of mobile devices and the rise of Internet of things, through the API to allow applications to access back-end systems and data become more and more common. Between different applications, API calls become more and more complex. Developers have to spend more time to develop and manage APIs. When the application developers or users do service discovery, they cannot make further judgments and cannot make effective call after obtains the candidate API.APIS' Safe and effective management is not easy for enterprises, API has become the cornerstone of Internet services like infrastructure, which related to an application development prospects, rapid and easy to build API and manage API has become the focus of the development of the Internet.Aiming at the above problems, this paper proposes an open service of the monitoring-oriented back-end API. It relies on the API management system to design and implement, and verify the usability of the system through testing. First of all, this thesis realizes the basic management of open API, namely data acquisition, data storage and version control.Secondly, it analyzes and realizes the function of selecting and adapting open API. The collection of the relevant QoS data of the open API adopts the way of intelligent agent. Finally, in order to guarantee the quality of open API, the paper puts forward the monitoring strategy of open API to guarantee not too much interference APIs' quality, and test and verify.In this paper, various functional modules of the system were tested and verified. The system's usability is proved by several tests of data acquisition module,data storage module,version control module,selection adaptation module and API quality parameter monitoring module. |
