Hello,

You can, for both and they would need to add those parameters to the code, for example here is the Go SDK for uploading; let me see if I can find an example where params has been added too.

Refer to below link:

https://www.digitalocean.com/docs/spaces/resources/s3-sdk-examples/#generate-a-pre-signed-url-to-upload-a-file

eg like this curl(but same thing in the Go code in needed), it has a header for content-type:

curl -X PUT \
-H “Content-Type: text” \
-d “The contents of the file.” \
“https://example-space-name.nyc3.digitaloceanspaces.com/new-file.ext?AWSAccessKeyId=EXAMPLE7UQOTHDTF3GK4&Content-Type=text&Expires=1580419378&Signature=YIXPlynk4BALXE6fH7vqbnwjSEw%3D”

Few more links, which will likely be helpful too:

https://docs.ceph.com/en/latest/radosgw/s3/
https://github.com/awsdocs/aws-doc-sdk-examples/blob/master/go/example_code/s3/s3_put_bucket_object_acl.go

Hope this helps!

Cheers,
