用Java强制下载的方法

Question

I need a way to 'force' the download of a file when the AJAX response of a Post is returned.

I can't use window.open() because I don't have an useful URL.

Is there any way using Javascript or Dojo toolkit to force the download of the file inside of the HTTP Response?

Answer 1

Your server needs to add the Content-Type and Content-Disposition headers to force a download.

Content-Type: application/octet-stream
Content-Disposition: attachment; filename=filename.ext
