【摘要】：近些年來(lái),移動(dòng)互聯(lián)網(wǎng)應(yīng)運(yùn)而生,隨之而來(lái)的是各類(lèi)Web服務(wù)的迅猛發(fā)展,一種新穎的Web服務(wù)架構(gòu)風(fēng)格越來(lái)越受到開(kāi)發(fā)者的重視與青睞,它就是REST架構(gòu)風(fēng)格,即Representational State Transfer(表述性狀態(tài)轉(zhuǎn)移),Roy Thomas Fielding在他的博士論文中首次闡述了其內(nèi)涵。作為一種設(shè)計(jì)分布式超媒體系統(tǒng)的架構(gòu)風(fēng)格,它為構(gòu)建下一代具有簡(jiǎn)單、高效,可伸縮,移植性強(qiáng)等優(yōu)點(diǎn)的Web服務(wù)提供了設(shè)計(jì)原則和約束,因而被稱(chēng)為Web服務(wù)設(shè)計(jì)的“新哲學(xué)”。 Web服務(wù)的支撐技術(shù)應(yīng)當(dāng)具備簡(jiǎn)單易懂、可伸縮、松耦合以及互聯(lián)網(wǎng)規(guī)模的特征,REST以5個(gè)必需的約束條件和1個(gè)可選約束條件實(shí)現(xiàn)了滿(mǎn)足上述需求的最簡(jiǎn)化設(shè)計(jì)。Ruby on Rails作為一款成熟的服務(wù)器端REST開(kāi)發(fā)框架已經(jīng)成為此架構(gòu)風(fēng)格的代表,非常適合基于REST的Web服務(wù)的開(kāi)發(fā),而且應(yīng)用越來(lái)越廣泛。 本文首先闡述REST框架風(fēng)格的約束條件以及面向?qū)ο蟮奶攸c(diǎn),其次在核心技術(shù)與服務(wù)特性?xún)煞矫媾c基于RPC架構(gòu)風(fēng)格實(shí)現(xiàn)的傳統(tǒng)Web服務(wù)進(jìn)行對(duì)比,詳細(xì)分析并闡述了RESTful Web服務(wù)的優(yōu)點(diǎn)。此外,針對(duì)泛在網(wǎng)絡(luò)、泛在學(xué)習(xí)以及泛在學(xué)習(xí)平臺(tái)提出一系列觀點(diǎn),并據(jù)此,開(kāi)發(fā)RESTful泛在學(xué)習(xí)平臺(tái)。 本文在實(shí)現(xiàn)泛在學(xué)習(xí)平臺(tái)的主要組件的基礎(chǔ)上,充分發(fā)揮REST架構(gòu)風(fēng)格的可伸縮性,針對(duì)用戶(hù)在使用平臺(tái)進(jìn)行學(xué)習(xí)和交流的實(shí)際過(guò)程中可能提出的新需求,通過(guò)整合第三方圖形化服務(wù)快速擴(kuò)展平臺(tái)原組件。實(shí)踐表明,基于REST架構(gòu)風(fēng)格的泛在學(xué)習(xí)平臺(tái)不僅能很好地滿(mǎn)足各種基本需求,而且可以通過(guò)強(qiáng)大的可伸縮性整合其它Web服務(wù)來(lái)增強(qiáng)平臺(tái)性能。
[Abstract]:In recent years, the mobile Internet emerged as the times require, followed by the rapid development of various Web services, a novel Web services architecture style is more and more attention and favor of developers, it is the REST architecture style,That is, Representational State transfer (Representational Thomas Fielding) explains its connotation for the first time in his doctoral thesis.As an architectural style of designing distributed hypermedia system, it provides design principles and constraints for building the next generation of Web services with the advantages of simplicity, efficiency, scalability, portability, etc.Therefore, it is called the "new philosophy" of Web service design.The supporting technologies for Web services should be easy to understand, scalable,Loosely coupled and Internet-scale features rest has become a mature server-side REST development framework with five necessary constraints and one optional constraint to achieve the most simplified design to meet these requirements.For this purpose, the representative of the architectural style,Very suitable for the development of Web services based on REST, and more and more widely used.This paper first describes the constraints of REST framework style and object-oriented characteristics, and then compares the core technology and service characteristics with the traditional Web services based on RPC architecture style.The advantages of RESTful Web service are analyzed in detail.In addition, a series of viewpoints on ubiquitous learning platform, ubiquitous learning platform and ubiquitous learning platform are put forward. Based on this, RESTful ubiquitous learning platform is developed.Based on the realization of the main components of the ubiquitous learning platform, this paper gives full play to the scalability of the REST architecture style, aiming at the new requirements that the users may put forward in the process of learning and communicating with the platform.Through the integration of third party graphical services to quickly extend the original platform components.Practice shows that the ubiquitous learning platform based on REST architecture style can not only meet all kinds of basic needs but also enhance platform performance by integrating other Web services with strong scalability.
