手順

1. Boto の auth.py ファイルを開いて編集します。

   1. 以下の 4 つの行をコードブロックに追加します。

      class SigV4Auth(BaseSigner):
        """
        Sign a request with Signature V4.
        """
        REQUIRES_REGION = True
      
        def __init__(self, credentials, service_name, region_name):
            self.credentials = credentials
            # We initialize these value here so the unit tests can have
            # valid values.  But these will get overriden in ``add_auth``
            # later for real requests.
            self._region_name = region_name
            if service_name == 'sts':

                self._service_name = 's3' 

      2

      
            else: 

      3

      
                self._service_name = service_name

      def _modify_request_before_signing(self, request):
              if 'Authorization' in request.headers:
                  del request.headers['Authorization']

      2

      
                  request.headers['X-Amz-Content-SHA256'] = self.payload(request)
