如何使用Lambda将文件从“文件夹”A复制到同一Bucket上的文件夹B

import boto3

def lambda_handler(event, context):
    s3 = boto3.client('s3')
    
    # 源文件的Bucket名称和文件夹路径
    source_bucket = event['Records'][0]['s3']['bucket']['name']
    source_key = event['Records'][0]['s3']['object']['key']
    
    # 目标文件的Bucket名称和文件夹路径
    destination_bucket = 'your_destination_bucket'
    destination_key = 'your_destination_folder/' + source_key.split('/')[-1]
    
    # 复制文件
    s3.copy_object(Bucket=destination_bucket, Key=destination_key, 
                   CopySource={'Bucket': source_bucket, 'Key': source_key})
    
    return {
        'statusCode': 200,
        'body': 'File copied successfully!'
    }
