The Research Of RESTful Web Services Building Based On Grails Framework

REST (Representational State Transfer) is an architecture style that can truly reflect the features of the Web. It is the key to understand the Web. The design principles of HTTP1.1protocol are revealed by the design idea of the REST. Today, Web is not only a content publishing platform, but also a global computing platforms. Web applications are mainly for the human users, and Web services are mainly for the programming users. SOAP, XML-RPC, and REST the three mainstream development of Web services implementations, compared with REST more easy-to-use resource-oriented model to expose its services, reduce development complexity and improve the systemscalability. The RESTful Web service is the best choice at this stage to develop Web services.Grails development framework in the Java language world learns many advantages from Ruby on Rails. In addition to the famous "convention over configuration", Grails has also can be run directly in JVM, rich plugin system, mature technology stack is worth developer attention characteristics. It is easy to develop the REST Web services specifications with Grails. Called as the agile development framework, Grails has many features that is worthy of the attention from developers. According to the research on the REST architecture and the Grails framework, this article hopes to develop Web services of RESTful by combining these two factors together. Fully reflects the efficient Grails agile development characteristics, as well as the REST architecture, lightweight, self-describing, stateless, easy-to-use features.The main work of this paper includes the following:studies on how to achieve the RESTful based on the HTTP protocol according to REST specification; designs unified application interface of RESTful HTTP; researches on the realization of the short URL RESTful Web services based on Grails MVC framework. The contents and results of this article can provide examples for the Web services by using of the Grails framework and can also provide a reference for designing RESTful HTTP.
