我目前在我看来有这段代码:
= link_to "Download", upload.upload.expiring_url, class: "btn btn-sm btn-success pull-right margin-right"
现在,这只是链接到文件并在浏览器中打开它。如何在单击链接时强制下载文件?

我最后听到了另一个答案(Allowing User to Download File from S3 Storage)
的建议我在上传控制器中添加了download_url方法:
def download_url(style_name=:original)
s3 = AWS::S3.new
@bucket ||= s3.buckets[upload.bucket_name]
@bucket.objects[upload.s3_object(style_name).key].url_for(:read,
:secure => true,
:expires => 24*3600,
:response_content_disposition => "attachment; filename='#{upload_file_name}'").to_s
end
然后在我看来我得到了:
= link_to "Download", upload.download_url

S3中的文件需要设置以下标题。
Content-Disposition: attachment; filename=FILENAME.EXT
Content-Type: application/octet-stream
检查回形针选项以查看它是否可以在文件上传时执行此操作。或者你可以在s3控制台中手动完成,一次一个文件。
