SignatureDoesNotMatch Error on Policy API Request

[cmather]

I've added a new method to my fork to get and set a bucket's policy since I couldn't find those methods in the s3interface class. I'm new to the code base so please let me know if I'm doing it wrong! However, I'm getting the SignatureDoesNotMatch error from AWS. If I change the url to something like "#{bucket}?location" it works fine. Am I not setting the header url properly? Or, is there something more devious happening? Thanks! Code Below:

module RightAws
  class S3Interface

    def get_bucket_policy(bucket, headers={})
      req_hash = generate_rest_request('GET', headers.merge(url: "#{bucket}?policy"))
      request_info(req_hash, S3HttpResponseBodyParser.new)
    end

  end
end

Hi Plz try get_acl method. I guess it does what you need
