ASP實現強制圖片下載函數

圖片不進行處理，圖片默認是用浏覽器打開顯示，如果希望圖片變為下載可以使用以下代碼

function downloadFile(strFile)
    strFilename = server.MapPath(strFile)
 
    Response.Buffer = True
    Response.Clear
 
    Set s = Server.CreateObject("ADODB.Stream")
    s.Open
 
    s.Type = 1
 
    on error resume next
 
    Set fso = Server.CreateObject("Scripting.FileSystemObject")
    if not fso.FileExists(strFilename) then
        Response.Write("<h1>Error:</h1>" & strFilename & " does not exist<p>")
        Response.End
    end if
 
    Set f = fso.GetFile(strFilename)
    intFilelength = f.size
 
    s.LoadFromFile(strFilename)
    if err then
        Response.Write("<h1>Error: </h1>" & err.Description & "<p>")
        Response.End
    end if
 
    Response.AddHeader "Content-Disposition", "attachment; filename=" & f.name
    Response.AddHeader "Content-Length", intFilelength
    Response.CharSet = "UTF-8"
    Response.ContentType = "application/octet-stream"
 
    Response.BinaryWrite s.Read
    Response.Flush
 
    s.Close
    Set s = Nothing
End Function

以上所述就是本文給大家分享的函數了，希望對大家學習asp能夠有所幫助。
