simplest-async-s3client 0.0.4

A simple async client for aws s3 storage

Simple async s3 client for immers.cloud

Source code https://github.com/Aberezhnoy1980/MarketGenius/tree/main/ds_app/src/clients/s3_client

Getting started

Get the access key, secret key and url (https://api.immers.cloud:8080) from immers.cloud and create an instance of the client:

from simple_async_s3client import S3Client


your_access_key = 'access_key'
your_secret_key = 'secret_key'
your_endpoint_url = 'endpoint_url'

s3_client = S3Client(
    access_key=your_access_key,
    secret_key=your_secret_key,
    endpoint_url=your_endpoint_url,
)

This client contains several methods for working with objects (files):

• If necessary, you can create a new bucket in the storage:

# For execute the coroutine you can use asyncio.
import asyncio

new_bucket_name = 'new_bucket_name'
asyncio.run(
    await s3_client.create_bucket(new_bucket_name)
)

• Uploading files. You can send one or more objects to the storage:

# For a single file
async def upload_file(file_path, bucket_name):
    await s3_client.upload_file(file_path, bucket_name)

file_path = '/path/to/your/file'
bucket_name = 'your bucket name'

asyncio.run(upload_file(file_path, bucket_name))

# For a group of files or a directory. For example, you have a directory with files
import os


async def upload_files(dir_path, bucket):
    files_list = os.listdir(dir_path)
    file_paths = [os.path.join(dir_path, file) for file in files_list]

    for file_path in file_paths:
        await s3_client.upload_file(file_path, bucket)


dir_path = '/path/to/your/directory'
bucket_name = "bucket_name"

asyncio.run(upload_files(dir_path, bucket_name))

• Getting a list of objects in storage:

async def get_file_list(bucket):
    obj_list = await s3_client.get_object_list(bucket)

    for item in obj_list:
        print(item["Key"], item["Size"])

bucket_name = 'bucket name'

asyncio.run(get_file_list(bucket_name))

• Getting object. The file will be created in the destination directory (use '.' for current):

async def get_file(bucket, file_name, destination):
    response = await s3_client.get_object(bucket, file_name, destination)
    print(response)

    
bucket_name = 'bucket name' 
file_name = 'file name' # can get from get_file_list()
destination = 'path/to/destination/directory'

asyncio.run(get_file(bucket_name, file_name, destination))

• Deleting files:

async def delete_file(bucket, objects_to_delete):
    resp = await s3_client.delete_objects(bucket, objects_to_delete)
    print(resp['ResponseMetadata']['HTTPStatusCode'])


objects_to_delete = [{"Key": "file_name"}]
bucket_name = "bucket name"

asyncio.run(delete_file(bucket_name, objects_to_delete))


# delete more than one file
async def delete_all(bucket):
    objects = await s3_client.get_object_list(bucket)
    objects_to_delete = []

    for obj in objects:
        objects_to_delete.append({'Key': obj['Key']})

    resp = await s3_client.delete_objects(bucket, objects_to_delete)
    print(resp['ResponseMetadata']['HTTPStatusCode'])


bucket_name = 'bucket name'

asyncio.run(delete_all(bucket_name))
