将嵌套的亚马逊S3文件夹复制到展平的文件夹中

import boto3

def flatten_s3_bucket(bucket_name, prefix=''):
    s3 = boto3.client('s3')
    paginator = s3.get_paginator('list_objects_v2')
    
    for page in paginator.paginate(Bucket=bucket_name, Prefix=prefix):
        if 'Contents' in page:
            for obj in page['Contents']:
                old_key = obj['Key']
                new_key = old_key.replace(prefix, '', 1).lstrip('/')
                
                if '/' in new_key:
                    new_key = new_key.replace('/', '_')
                
                s3.copy_object(
                    CopySource={'Bucket': bucket_name, 'Key': old_key},
                    Bucket=bucket_name,
                    Key=new_key
                )
                s3.delete_object(Bucket=bucket_name, Key=old_key)

# 示例调用
flatten_s3_bucket('your-bucket-name', 'your-prefix/')
