ディレクトリバケットのオブジェクトの削除

次の例では、AWS SDK for Java 2.x を使用してディレクトリバケット内のオブジェクトを削除します。

static void deleteObject(S3Client s3Client, String bucketName, String objectKey) {


        
        try {
            
            DeleteObjectRequest del = DeleteObjectRequest.builder()
                    .bucket(bucketName)
                    .key(objectKey)
                    .build();

            s3Client.deleteObject(del);
            
            System.out.println("Object " + objectKey + " has been deleted");
            
            
        } catch (S3Exception e) {
            System.err.println(e.awsErrorDetails().errorMessage());
            System.exit(1);
        }
        
    }

次の例では、AWS SDK for Python (Boto3) を使用してディレクトリバケット内のオブジェクトを削除します。

import logging
import boto3
from botocore.exceptions import ClientError

def delete_objects(s3_client, bucket_name, objects):
    '''
    Delete a list of objects in a directory bucket

    :param s3_client: boto3 S3 client
    :param bucket_name: Bucket that contains objects to be deleted; for example, 'doc-example-bucket--usw2-az1--x-s3'
    :param objects: List of dictionaries that specify the key names to delete
    :return: Response output, else False
    '''

    try:
        response = s3_client.delete_objects(
            Bucket = bucket_name,
            Delete = {
                'Objects': objects
            } 
        )
        return response
    except ClientError as e:
        logging.error(e)
        return False
    

if __name__ == '__main__':
    region = 'us-west-2'
    bucket_name = 'BUCKET_NAME'
    objects = [
        {
            'Key': '0.txt'
        },
        {
            'Key': '1.txt'
        },
        {
            'Key': '2.txt'
        },
        {
            'Key': '3.txt'
        },
        {
            'Key': '4.txt'
        }
    ]
    
    s3_client = boto3.client('s3', region_name = region)
    results = delete_objects(s3_client, bucket_name, objects)
    if results is not None:
        if 'Deleted' in results:
            print (f'Deleted {len(results["Deleted"])} objects from {bucket_name}')
        if 'Errors' in results:
            print (f'Failed to delete {len(results["Errors"])} objects from {bucket_name}')
