我们从Python开源项目中，提取了以下6个代码示例，用于说明如何使用botocore.exceptions.UnknownClientMethodError()。
def generate_presigned_url(self, ClientMethod, Params=None, ExpiresIn=3600, HttpMethod=None): """Generate a presigned url given a client, its method, and arguments :type ClientMethod: string :param ClientMethod: The client method to presign for :type Params: dict :param Params: The parameters normally passed to ``ClientMethod``. :type ExpiresIn: int :param ExpiresIn: The number of seconds the presigned url is valid for.
