Question

下面的ASP代码抓取文件的内容（thisoutfile - 其GUID作为其文件名）并将其流式传输到浏览器，提供要保存的建议文件名。这适用于除chrome之外的所有浏览器，其中提供的文件名是脚本本身的名称，即使文件名（thisfname）是单个单词也是如此。如果您实际将文件保存为xls或pdf，则将其保存为OK。

知道为什么吗？

Set fs=Server.CreateObject("Scripting.FileSystemObject")
Set f=fs.GetFile(thisoutfile)

Set adoStream = CreateObject("ADODB.Stream")
adoStream.Open()
adoStream.Type = 1
adoStream.LoadFromFile(f.Path)
dataSize = f.size
Response.Buffer = true
Response.CharSet = "UTF-8"
Response.clear
select case ext
    case "xls"
        response.contentType="application/vnd.ms-excel"
    case else
        Response.ContentType = "application/x-unknown" ' arbitrary
end select
Response.AddHeader "Content-Length", dataSize
Response.AddHeader "Content-Disposition","attachment;filename=""" & thisfname & ""

Response.flush
do while not adoStream.eos
    Response.BinaryWrite adoStream.Read(1024 * 8)
    Response.flush
loop
Response.End()
adoStream.close
set adoStream=nothing
set f=nothing
set fs=nothing

Answer 1

Content-Disposition标题中缺少双引号，而Chrome似乎并不宽容。将该行代码更改为

Response.AddHeader "Content-Disposition","attachment;filename=""" & thisfname & """"

Chrome不尊重ado.stream文件名
