Issue #
fixes awslabs/aws-sdk-kotlin#1029
Description of changes
SignedBodyHeader
execution context attribute when the operation has the unsigned payload trait or is an event stream input. When set the signer will add thex-amz-content-sha256
header to the canonical request and set the header.shouldSignHeader
predicate to theAwsHttpSigner.Config
. This was missing and allows auth scheme overrides to augment the set of signed headers. This allowed me to narrow down the issue since we include a few more headers than AWS CLI did. This should have been possible previously and I was surprised it wasn't.By submitting this pull request, I confirm that my contribution is made under the terms of the Apache 2.0 license.
