S3 Metadata

[cgc]

The API doesn't seem to permit for modification of S3 metadata, either through operations or file attributes. If there exists a way, I can't find it in code samples.

What kind of metadata do you mean?

[cgc]

Files can't have their Content-Type modified, and in the case of files copied from in-memory files, can't set their Content-Type. Additionally, I don't know of a way to tweak other HTTP Headers or add arbitrary metadata.

After 10 years, is there a solution to this problem?

I think this issue has fixed, because the ObjectMetadataHolder::sendWith has replace metadata.clone() with deepMetadataClone(), and the first do not clone the Content-Type.

request.setMetadata(deepMetadataClone());
