Chrome不遵守ado.stream文件名

Question

下面的ASP代码抓取了一个文件（thisoutfile--其中包含一个GUID作为文件名）的内容并将其流式传输到浏览器，并提供建议的文件名以保存为。这适用于除chrome外的所有浏览器，即使文件名（thisfname）是单个字，文件名所提供的也是脚本本身的名称。如果你真的将文件保存为xls或pdf，那么它可以保存它。

任何想法为什么？

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

Content-Disposition标题中缺少双引号，看起来Chrome并非那么宽容。将该行代码更改为

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