Research On The Self-adaptive Framework Of Ajax API

With the continuous emergence of Opening Platform,the number of OpenAPI is growing rapidly.Moreover,Ajax API is the important content in Open API.Recently,web developers often use Ajax API to build the rich Internet application(RIA).It is more important for how to guarantee the stability of Ajax API in the RIA.Due to the uncertainty of the environment,automatically switching among different Ajax APIs with similar functionality is important to guarantee the end-to-end performance.We make a research on the Ajax API deeply,and we propose a self-adaptive method on the Ajax API with the idea of self-adaptive software.In this paper,we propose a framework to address the self-adaption and difficulty in invoking Ajax API.The Ajax API wrapping model,consisting of the specific and abstract components,is proposed to automatically construct the grammatical and functional semantic relations between Ajax APIs.Then switching module is introduced to support the automatic switching among different Ajax APIs,according to the user preference and QoS of Ajax APIs.Taking the map APIs,i.e.Baidu Map,Gaode Map,Tencent Map and so on as an example,the demo shows that the framework can facilitate the construction of RIA and improve adaptability of the application.The process of selection and switching in the different Ajax APIs is automatic and transparent to the users.In summary,we proposed for the API Ajax of the package model and adaptive mechanism,and the adaptive mechanism used in Mashup construction.These mechanisms can guarantee the stability of Web application to some extent.
