有没有办法使用boto3获得亚马逊网络服务的S3存储桶总成本？

import boto3

def get_s3_bucket_cost():
    client = boto3.client('ce', region_name='us-east-1')  # 创建Cost Explorer客户端
    
    response = client.get_cost_and_usage(
        TimePeriod={
            'Start': '2022-01-01',
            'End': '2022-01-31'
        },
        Granularity='MONTHLY',
        Metrics=[
            'UnblendedCost',
        ],
        Filter={
            'Dimensions': {
                'Key': 'SERVICE',
                'Values': [
                    'Amazon Simple Storage Service'
                ]
            }
        }
    )
    
    # 解析响应，获取S3存储桶的总成本
    total_cost = response['ResultsByTime'][0]['Total']['UnblendedCost']['Amount']
    
    return total_cost

s3_bucket_cost = get_s3_bucket_cost()
print("S3存储桶的总成本为：", s3_bucket_cost)
