【摘要】：目前移動(dòng)互聯(lián)網(wǎng)的發(fā)展正處在歷史性的轉(zhuǎn)折點(diǎn),移動(dòng)智能終端和應(yīng)用處于高速發(fā)展階段,移動(dòng)應(yīng)用作為移動(dòng)互聯(lián)網(wǎng)的主角,是推動(dòng)未來移動(dòng)互聯(lián)網(wǎng)發(fā)展的主要力量。然而,以HTML5為代表的移動(dòng)Web技術(shù)尚處于發(fā)展的初級(jí)階段,標(biāo)準(zhǔn)本身在向不斷完善和改進(jìn)空間演進(jìn),且相比本地應(yīng)用移動(dòng)智能終端仍存在執(zhí)行HTML5效率低、設(shè)備調(diào)用能力受限、能耗較大等問題,都影響著移動(dòng)Web應(yīng)用的體驗(yàn)。 本文從移動(dòng)Web開發(fā)存在移動(dòng)瀏覽器內(nèi)核種類繁多、屏幕尺寸多樣化、設(shè)備性能參差不齊等現(xiàn)狀出發(fā),研究移動(dòng)Web前端性能優(yōu)化方案,并設(shè)計(jì)與實(shí)現(xiàn)了一種移動(dòng)圖片社交Web應(yīng)用,對(duì)優(yōu)化方案的可行性進(jìn)行了驗(yàn)證。 首先,本文從移動(dòng)Web前端渲染優(yōu)化、圖片優(yōu)化、緩存優(yōu)化和網(wǎng)絡(luò)連接優(yōu)化四個(gè)角度著手,提出移動(dòng)Web前端性能優(yōu)化模型,以縮短頁面加載、渲染時(shí)間,提升用戶體驗(yàn)。 然后,針對(duì)人們生活中的實(shí)際社交需求,設(shè)計(jì)了一個(gè)群組照片共享的移動(dòng)圖片社交Web應(yīng)用,進(jìn)行了功能需求分析,給出了系統(tǒng)功能模塊的設(shè)計(jì)方案,并實(shí)現(xiàn)系統(tǒng)的總體架構(gòu)及各個(gè)組成部分。 最后,針對(duì)上述移動(dòng)圖片社交Web應(yīng)用實(shí)例,設(shè)計(jì)并執(zhí)行優(yōu)化方案,使用前端性能工具輔助對(duì)比優(yōu)化前后實(shí)際效果,驗(yàn)證了優(yōu)化方案的可行性。
[Abstract]:At present, the development of mobile Internet is at a historic turning point. Mobile intelligent terminals and applications are in the stage of rapid development. Mobile applications, as the protagonists of mobile Internet, are the main force to promote the development of mobile Internet in the future. However, the mobile Web technology represented by HTML5 is still in the initial stage of development, and the standard itself is evolving to perfect and improve the space continuously. Compared with the local application mobile intelligent terminal, the execution efficiency of HTML5 is still low, and the device transfer ability is limited. Large energy consumption and other problems affect the experience of mobile Web applications. In this paper, a mobile Web front-end performance optimization scheme is studied, and a mobile picture social Web application is designed and implemented based on the present situation of mobile Web development, such as the variety of mobile browser kernel, the diversity of screen size and the uneven performance of mobile Web. The feasibility of the optimization scheme is verified. Firstly, from four aspects of mobile Web front-end rendering optimization, picture optimization, cache optimization and network connection optimization, this paper proposes a mobile Web front-end performance optimization model to shorten page loading, render time and improve user experience. Then, according to the actual social needs of people in life, a mobile picture social Web application of group photo sharing is designed, and the function requirement analysis is carried out, and the design scheme of the system function module is given. And realize the overall structure of the system and each component. Finally, for the above mobile picture social Web application example, the optimization scheme is designed and executed. The feasibility of the optimization scheme is verified by using front-end performance tools to help compare the actual results before and after optimization.
