示例1: sign

# 需要导入模块: from botocore import exceptions [as 别名]
# 或者: from botocore.exceptions import UnsupportedSignatureVersionError [as 别名]

        :param request: The request object to be sent over the wire.

        :param region_name: The region to sign the request for.

            three possible values:

            * 'standard'     - This should be used for most requests.

            * 'presign-post' - This should be used when pre-signing an S3 post.

        :type expires_in: int
