AWS / Amazon Signature v4 Signing Process authentication plugin for HTTPie.
$ pip install --upgrade httpie-aws-authv4
You should now see aws4 under --auth-type / -A in $ http --help output.
This authentication plugin looks for credentials in the same precedence that the AWS CLI tool does. At the moment, the plugin only looks at the default profile for credentials stored in credentials file.
$ http --auth-type aws4 https://asdf123a9sas.execute-api.ap-southeast-2.amazonaws.com/dev/test
$ http --auth-type aws4 --auth ACCESSKEYXXX:AWSSECRETKEYXXX https://asdf123a9sas.execute-api.ap-southeast-2.amazonaws.com/dev/test
If for some reason you are not hitting the AWS endpoint directly (common with API Gateway), you will need to specify the AWS provided endpoint on the CLI. This is used to determine the service and region values required for the signature process.
$ http --auth-type aws4 --auth asdf123a9sas.execute-api.ap-southeast-2.amazonaws.com https://api.awesomeservice.net/dev/test
$ http --auth-type aws4 --auth ACCESSKEYXXX:AWSSECRETKEYXXX:asdf123a9sas.execute-api.ap-southeast-2.amazonaws.com https://api.awesomeservice.net/dev/test
All of the heavy lifting (the signing process) is handled by aws-requests-auth
