2018-09-06 10:29
格式：Download.asp?FileName=要下载的文件名
复制代码 代码如下:
Dim Stream
Dim Contents
Dim FileName
Dim FileExt
Const adTypeBinary = 1
FileName = Request.QueryString(FileName)
if FileName = Then
Response.Write 无效文件名.
Response.End
End if
下面是不希望下载的文件
FileExt = Mid(FileName, InStrRev(FileName, .) + 1)
Select Case UCase(FileExt)
Case ASP, ASA, ASPX, ASAX, MDB
Response.Write 受保护文件,不能下载.
Response.End
End Select
下载这个文件
Response.Clear
Response.AddHeader content-disposition, attachment; filename= & FileName
Set Stream = server.CreateObject(ADODB.Stream)
Stream.Type = adTypeBinary
Stream.Open
Stream.LoadFromFile Server.MapPath(FileName)
While Not Stream.EOS
Response.BinaryWrite Stream.Read(1024 * 64)
Wend
Stream.Close
Set Stream = Nothing
Response.Flush
Response.End
