通过ASP下载文件(源码)

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

%>
