Does minio have a config to change the mime Type in the response based on file type?

Bill Thorp 21 minutes ago
I believe this is just stored as metadata, and we may be defaulting to the application/octet-stream if the user doesn't set this via their S3 client. It would make sense to try to look it up by file extension, I'm not seeing this logic in my search of the Minio code yet

Does uplink set content-type when uploading?

Not sure if aws cli does....

I'm afk, but would test if aws cli upload to us for an image preserves mime

Same with uplink in the metadata

Likely you guys should confirm your test coverage for content type preservation for these workflows

If someone uploads something with [gateway-mt, linksharing, uplink] does the content/type get set correctly in [gateway-mt, linksharing, uplink]? What if the type is not set, can it be guessed from file extension? We think that Gateway-MT does not guess the content type, but linksharing does. What does Amazon do? -MT should if Amazon does for sure.

AWS CLI does guess the type when uploading a file, although it's conceivable it could get that wrong if you don't have the mime types loaded somewhere on your machine (e.g. /etc/mime.types). You can also disable guessing with --no-guess-mime-type, or set --content-type to whatever you want to override any guesses. Storj S3 gateway and AWS S3 will set binary/octet-stream as a default if nothing was sent from the client. S3 SDKs will send application/octet-stream as a default if no ContentType parameter was set when uploading an object, so it's all highly dependent on the client.

It looks like we're doing what S3 does.

I'll look at documenting the above for gateway somewhere.
