I need to send it to another service, and get the upload URL with correct Content-Type.

CodePudding user response：

You could use the put_object method on the bucket instance that accepts a hash of options, one of which is content-type (Reference):

def upload_file(file)
  object_key = "#{Time.now.to_i}-#{file.original_filename}"
  @s3_bucket.put_object({ 
    key: object_key, 
    body: Pathname.new(file.path),
    content_type: "some/content_type" 
  })
end
