第二种:
复制代码 代码如下:
<% '定义函数，用ADODB.Stream读取二进制数据 Function ReadBinaryFile(FileName) Const adTypeBinary = 1 Dim BinaryStream Set BinaryStream = CreateObject("ADODB.Stream") BinaryStream.Type = adTypeBinary BinaryStream.Open BinaryStream.LoadFromFile FileName ReadBinaryFile = BinaryStream.Read End Function Response.AddHeader "Content-Disposition", "attachment;filename=2.gif"'文件名 Response.ContentType = "image/GIF" '设置（1） response.Binarywrite ReadBinaryFile(server.mappath("2.gif"))'就是你读取存在本地的文件，防止被 别人知道真实路径盗连的。 %>
