I wanted to delete multiple objects in s3 with boto3

install boto3

$ pip3 install boto3

Settings for accessing s3 are file

aws.py


import boto3

s3 = boto3.client(
    's3',
    aws_access_key_id = {access key},
    aws_secret_access_key = {secret_access_key},
    region_name = 'ap-northeast-1')
    
s3_bucket = 'sample-app'

Create a method to operate s3

services/s3_service.py


from aws import s3, s3_bucket

class S3Service:

    #Get the contents of an object
    def get_object():
        s3_dir = 'image/sample.json'
        sample_json = s3.get_object(Bucket=s3_bucket, Key=s3_dir)
        body = sample_json['Body'].read()

        print(body.decode('utf-8'))

    #Get multiple objects
    def get_objects(id):
        s3_dir = 'image/{0}/'.format(id)
        image_objs = s3.list_objects_v2(Bucket=s3_bucket, Prefix=s3_dir)

        for image in image_objs['Contents']: 
            print(image['Key'])

    #Delete multiple objects
    def delete_objects(id):
        s3_dir = 'image/{0}/'.format(id)
        image_objs = s3.list_objects_v2(Bucket=s3_bucket, Prefix=s3_dir)

        for obj in image_objs['Contents']: 
            key = obj['Key']
            s3.delete_object(Bucket=s3_bucket, Key=key)

call service class

controller/image_controller.py


from flask import Blueprint, make_response
from services.s3_service import S3Service

# set route
sample_controller = Blueprint('sample_controller_router', __name__)

@sample_controller.route('/delete/<id>', methods=['PUT'])
def delete_images(id):
   S3Service.delete_objects(id)
   return make_response(jsonify({'code': 200}))
