教你通過(guò)ASP下載文件(源碼)

本文介紹的是通過(guò)ASP下載文件(源碼)的實(shí)例，希望對(duì)大家有所幫助。

Sometimes you want a user to download a binary file instead of opening it inside the browser window.
There are several different ways to accomplish this.
Generically:
<%
FileName = "Document.Doc"
Response.ContentType = "application/octet-stream"
Response.AddHeader "content-disposition", "attachment; filename =" & filename
Set Stream = Server.CreateObject("ADODB.Stream")
Stream.Open
Stream.LoadFromFile Server.MapPath(Filename)
Conents = Stream.ReadText
Response.BinaryWrite Contents
Stream.Close
Set Stream = Nothing
%>

If you know the file type that you would like the user to download, try:
<%
Filename = "document.doc"
Response.ContentType = "application/vnd.ms-word"
Response.AddHeader "content-disposition", "attachment; filename=" & filename
%>
