| 摘 要： | 基于Web的大文件上传是Web应用系统中经常遇到的问题。目前,基于Web的大文件上传组件比较缺乏,且不支持断点续传。在.NET框架下,利用JavaScript和ADODB.Stream技术实现了文件的分块读取,利用XMLHttp技术实现文件块的异步发送,然后在服务器端接收文件块并记录接收日志,在此基础上实现了文件的断点续传,且传输速度较快,对文件的大小没有限制。

| Abstract: | Web based big file uploading is a common problem in web applications. At present, there are few web-based big file uploading components available, and none of them supports resumption from interrupted transfers. This paper implements a new big file uploading method, which supports resumption from interrupted transfers. File blocks are read using JavaScript and ADODB.Stream, and are transferred asynchronously using XMLHttp, and then log is placed on the server when received. The transfer speed is improved greatly, and there is no limitation for file size using this method. |
