JS中实现重命名并下载文件

js干不了这个事。可以由服务端来做这件事。

Response.AddHeader("Content-Disposition", "attachmentfilename=\"" +filename+ "\"")

download.aspx

string fileName = ""//客户端保存的文件名

string filePath = Server.MapPath("")//路径

FileInfo fileInfo = new FileInfo(filePath)

Response.Clear()

Response.ClearContent()

Response.ClearHeaders()

Response.AddHeader("Content-Disposition", "attachmentfilename=" + fileName)

Response.AddHeader("Content-Length", fileInfo.Length.ToString())

Response.AddHeader("Content-Transfer-Encoding", "binary")

Response.ContentType = "application/octet-stream"

Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312")

Response.WriteFile(fileInfo.FullName)

Response.Flush()

Response.End()
