在IE进行文档链接时,如果遇到OLE支持的文档,IE会自动调用相应程序打开它,有时候这种功能并不是我们所需的,虽然我们可以提醒用户用鼠标右键-->"目标另存为...."命令来下载文档,但这样毕竟不太友好,本文描述了利用FSO及Stream方法实现IE直接下载文档.
<%@ language=vbscript codepage=65001%>
<%
‘’Filename must be input
if Request("Filename")="" then
response.write "<h1>Error:</h1>Filename is empty!<p>"
else
call downloadFile(replace(replace(Request("Filename"),"\",""),"/",""))
Function downloadFile(strFile)
‘’ make sure you are on the latest MDAC version for this to work
‘’ get full path of specified file
strFilename = server.MapPath(strFile)
‘’ clear the buffer
Response.Buffer = True
Response.Clear
‘’ create stream
Set s = Server.CreateObject("ADODB.Stream")
s.Open
‘’ Set as binary
s.Type = 1
‘’ load in the file
on error resume next
‘’ check the file exists
Set fso = Server.CreateObject("Scripting.FileSystemObject")
if not fso.FileExists(strFilename) then
Response.Write("<h1>Error:</h1>"&strFilename&" does not exists!<p>")
Response.End
end if
‘’ get length of file
Set f = fso.GetFile(strFilename)
intFilelength = f.size
s.LoadFromFile(strFilename)
if err then
Response.Write("<h1>Error: </h1>Unknown Error!<p>")
Response.End
end if
‘’ send the headers to the users Browse
Response.AddHeader "Content-Disposition","attachment; filename="&f.name
Response.AddHeader "Content-Length",intFilelength
Response.CharSet = "UTF-8"
Response.ContentType = "application/octet-stream"
‘’ output the file to the browser
Response.BinaryWrite s.Read
Response.Flush
‘’ tidy up
s.Close
Set s = Nothing
End Function
end if
