【摘要】：目前云存儲服務(wù)產(chǎn)品種類繁多，在嘗試使用云存儲解決方案來運作實際項目時，可能會遇到接口不統(tǒng)一、數(shù)據(jù)難共享、后期維護不便等問題。為了實現(xiàn)同樣的功能，開發(fā)人員需要編寫幾乎全然不同的代碼，閱讀并理解多份接口文檔。從客觀上來講，這些差異會給云存儲的發(fā)展帶來了諸多困難。 為了解決這些問題，本文提出了一種可行的標(biāo)準(zhǔn)化云存儲服務(wù)訪問接口。接口基于REST風(fēng)格設(shè)計，經(jīng)過理論研究與編碼實踐，開發(fā)出了可標(biāo)準(zhǔn)化訪問Google云和百度云的云存儲接口插件。本文的主要研究工作包括： (1)針對云存儲的差異化問題，討論并研究了當(dāng)前的云存儲服務(wù)架構(gòu)、接口的提供方式等基礎(chǔ)知識。論文把重點放在REST技術(shù)的研究之上，并把它與其它幾種主流的云存儲服務(wù)接口進行了比對。論文認為基于HTTP的REST設(shè)計風(fēng)格，是實現(xiàn)云存儲服務(wù)接口的首選技術(shù)。 (2)為了屏蔽用戶與云存儲交互時數(shù)據(jù)的不一致性，論文根據(jù)多個云存儲產(chǎn)品接口的特點，設(shè)計了一種基于REST的云存儲服務(wù)接口規(guī)范，給出了基本的資源操作方法，并對訪問的安全性、權(quán)限操作、錯誤響應(yīng)做了詳細定義。 (3)編碼并實現(xiàn)了一個COM插件，，它是根據(jù)論文中提出的REST風(fēng)格云存儲服務(wù)接口進行開發(fā)的。插件通過中間數(shù)據(jù)轉(zhuǎn)換，使開發(fā)者可以使用同一套規(guī)則訪問不同的云存儲服務(wù)，減少編碼量，提高開發(fā)速度，降低學(xué)習(xí)成本。 (4)對插件進行比對測試與應(yīng)用測試。比對測試是使用原生接口、其它類庫及接口插件的調(diào)用測試，實驗結(jié)果表明插件在代碼量、數(shù)據(jù)統(tǒng)一性方面更為優(yōu)秀。應(yīng)用測試則開發(fā)了Windows Phone應(yīng)用軟件，使用插件完成對Google云、百度云的訪問，插件的運行情況良好，操作響應(yīng)都在可接受范圍之內(nèi)。
[Abstract]:At present, there are many kinds of cloud storage service products. When we try to use cloud storage solution to run the actual project, we may encounter some problems, such as the interface is not uniform, the data is difficult to share, and the later maintenance is not convenient. To do the same, developers need to write almost entirely different code, read and understand multiple interface documents. Objectively speaking, these differences will bring many difficulties to the development of cloud storage. In order to solve these problems, this paper proposes a feasible standardized cloud storage service provider interface. The interface is designed based on REST style. Through theoretical research and coding practice, a cloud storage interface plug-in with standardized access to Google cloud and Baidu cloud is developed. The main work of this paper is as follows: (1) aiming at the problem of cloud storage differentiation, the basic knowledge of cloud storage service architecture and interface is discussed and studied. This paper focuses on the research of REST technology and compares it with other mainstream cloud storage service interfaces. The paper thinks that REST design style based on HTTP is the preferred technology to realize cloud storage service interface. (2) in order to shield the data inconsistency between user and cloud storage, according to the characteristics of multiple cloud storage product interfaces, a cloud storage service interface specification based on REST is designed, and the basic resource operation method is given. And access security, permission operation, error response is defined in detail. (3) A COM plug-in is coded and implemented, which is developed according to the REST style cloud storage service interface proposed in this paper. The plug-in can use the same set of rules to access different cloud storage services, reduce the amount of coding, improve the speed of development, and reduce the cost of learning. (4) compare and test the plug-in with application test. The comparison test is a call test using native interface, other class libraries and interface plug-ins. The experimental results show that the plug-in is better in code volume and data unity. Application test has developed Windows Phone application software, using plug-in to complete the access to Google cloud, Baidu cloud, the plug-in runs well, the operation response is within acceptable range.
