基于Web的大文件高效上传方法

High Efficient Upload Method of Large Files Based on Web

随着互联网、HTML5等技术的发展,文件上传在Web端的应用越来越普遍,同时对文件上传,特别是大文件上传的效率、稳定性、安全性、普适性等要求也越来越高,然而目前多数文件上传方式均不能很好的满足这些要求.因此,本文提出文件分片和多并发传输方法,提高大文件传输效率,从而解决Web前端多并发传输控制以及同一文件重复多次上传等问题.

With the development of Internet and HTML5 technology,the application of file upload on the Web is more and more popular.At the same time,the requirement of efficiency,stability,security and universality of file upload,especially large file upload,is higher and higher.However,most of the current file upload methods can not meet these requirements very well.Therefore,this study proposes to use file fragmentation and multi-concurrent transmission method to improve the efficiency of large file transmission,so as to solve the related problems of multi-concurrent transmission control in the front end of the Web and repeated upload of the same file.
