Download links for .txt (and .yaml) attachments show raw text instead of dowload

[CharlesGWaldman]

on our Discourse instance, if a user uploads a .txt or .yaml file as an attachment, the filename is shown as a download link:

but clicking on these does not download the file, it opens a new browser tab with the raw text, loading from an URL like

https://discourse-attachments.s3.dualstack.us-west-2.amazonaws.com/original/2X/4/xxxxxxxx.txt

How to make the download link actually download the file? Enabling “Secure uploads” was suggested as an option but after reading about that I’m a bit hesitant to enable it.

Thanks,

yea this is likely a configuration problem with your forum, perhaps to do with CDN or S3.

i could be wrong, but i believe it is how uploads are being served on your forum, whether it’s local storage or S3 /object/ CDN. it could be the HTTP response header?

i think if the content-dispostion: attachment header is present, browsers should usually download the file, but if it is missing, browsers often open .txt / .yml.

^ that .yml file should download as expected.

edit: i think this topic may be relevant:

Cannot download non-image media files, original filenames lost when uploaded to S3

Non-image media files residing on local storage or those migrated to S3 using rake uploads:migrate_to_s3 are downloaded with original filenames when clicking the upload link, while non-image media files uploaded directly to S3 are opened in new tab and the original filename is lost. rake uploads:migrate_to_s3 sets content_disposition for all non-image uploads while upload to s3 sets content_disposition for all non-media uploads only The fix is to replace is_supported_media with is_support…
