【摘要】：在移動互聯(lián)網(wǎng)飛速發(fā)展的今天,智能手機的覆蓋率越來越高,已經(jīng)成為人們接入互聯(lián)網(wǎng)的主要入口之一,智能手機就像一個移動著的個人中心一樣,人們通過它隨時進行社交、娛樂甚至工作,移動互聯(lián)網(wǎng)正在深刻的影響并改變著我們的生活。 在信息時代里,萬事都追求效率,用戶對實時通信的要求越來越高,比較成熟的實時通信方案主要是基于輪詢技術和HTTP流方式,它們雖然實現(xiàn)了實時的效果,但是效率低,不適合當今越來越復雜的網(wǎng)絡應用。同時很多實時應用都是本地APP,它的缺點是要針對不同的手機操作系統(tǒng)做適配,并且實現(xiàn)技術有一定難度,總體上開發(fā)維護成本比較高。IITML5給移動互聯(lián)網(wǎng)帶來了新的動力,是一次技術改革。智能手機的瀏覽器對HTML5的支持度比較好,一直以來它都是瀏覽網(wǎng)頁的入口,有了HTML5以后它也有可能成為用戶接觸接入Web應用的第一入口,因此在智能手機上Web APP將有可能成為行業(yè)的未來。 本文分析了以往的實現(xiàn)實時通信方法的技術原理,了解了它們在當今互聯(lián)網(wǎng)應用中存在的不足之后,對HTML5WebSocket這種全雙工雙向通信的技術進行了深入的研究,仔細研究了協(xié)議本身以及它相對于以往實現(xiàn)實時通信方案的優(yōu)點,最后設計并實現(xiàn)了基于HTML5WebSocket的智能手機聊天室,通過測試用例驗證各部分功能均可以正常使用,完成了基于WebSocket對實時Web APP開發(fā)的探索。
[Abstract]:With the rapid development of mobile Internet, the coverage of smart phones is becoming higher and higher, which has become one of the main entry points for people to connect to the Internet. Smart phones are like a mobile personal center, through which people can socialize at any time. Entertainment and even work, mobile Internet is profoundly affecting and changing our lives. In the information age, everything pursues efficiency, and users have higher and higher requirements for real-time communication. The more mature real-time communication schemes are mainly based on polling technology and HTTP stream mode. Although they achieve real-time effects, they are inefficient. Not suitable for today's increasingly complex network applications. At the same time, many real-time applications are local APPs. Its disadvantage is to adapt to different mobile phone operating systems, and it is difficult to implement the technology. In general, the development and maintenance cost is relatively high. IITML5 has brought new power to the mobile Internet. It was a technological reform. The smartphone browser has a good degree of support for HTML5. It has always been the portal to browse the Web. With HTML5, it may also become the first entry point for users to access Web applications. So Web APP on smartphones is likely to be the future of the industry. This paper analyzes the technical principle of realizing real-time communication methods in the past, understands their shortcomings in Internet application nowadays, and makes a deep research on HTML5WebSocket, which is a full duplex two-way communication technology. The protocol itself and its advantages compared with the previous real-time communication schemes are carefully studied. Finally, a smart phone chat room based on HTML5WebSocket is designed and implemented, and the test cases are used to verify that each part of the functions can be used normally. The exploration of real-time Web APP development based on WebSocket is completed.
