Not able to set content_disposition for object.presigned_url

[bonniesimon]

I can't seem to set content_disposition for object.presigned_url

    s3_object = Aws::S3::Object.new(
        BUCKET_NAME,
        s3_key,
        { client: s3_client }
      )

    s3_object.presigned_url(
      :upload_part,
      part_number:,
      upload_id:,
      key: s3_key,
     content_disposition: "attachment"
    )

The above will throw an exception {"error":"unexpected value at params[:content_disposition]"}

When stepping in through the debugger, this is coming from

aws-sdk-ruby/gems/aws-sdk-s3/lib/aws-sdk-s3/presigner.rb

Line 148 in 6743619

[req.send_request.data, x_amz_headers]

Thanks for opening up a discussion. I think the member you are looking for is called response_content_disposition

https://docs.aws.amazon.com/sdk-for-ruby/v3/api/Aws/S3/Types/GetObjectRequest.html#response_content_disposition-instance_method

I did try setting that. It gave me the same error.

Note that here I'm trying to upload a file in multipart manner. Hence, I create presigned_url for each individual parts. And I'm unable to set the content disposition of the whole content.

Ah! I see. Looking at upload_part, there doesn't appear to be content disposition. It looks like you need to set that on create_multipart_upload when you first get your upload_id.
