摘　　要：为了解决在线学习系统文件上传的效率低、稳定差等问题,提出了一种基于分片的文件断点续传方法,使用WebUpload组件在前端对文件进行分片和多线程设置,实现了文件秒传、断点续传,解决了相同文件重复上传的问题和上传失败后要全部重新上传的问题,并通过多线程上传的设计,有效提高了文件上传的效率,该方法运用到华南理工大学特色专业在线学习平台,取得了较好的效果。In order to solve the problem of efficiency and stability of online learning system file upload,a file breakpoint continuous transmission method based on file segmentation is proposed.The WebUpload component is used to set the file segmentation and multithreading on the front end,realizing fast file upload and file breakpoint resume,solving the problem of repeated file upload and the problem of all files to be uploaded again if the file upload fails.And through the design of file multi thread upload,the efficiency of file upload is effectively improved.This method has been applied to the online learning platform of characteristic majors of South China University of Technology,and achieved good results.
