The simple module for putting and getting object from Amazon S3 compatible endpoints

Installation

Usage

from http import HTTPStatus

from aiohttp import ClientSession
from aiohttp_s3_client import S3Client


async with ClientSession(raise_for_status=True) as session:
    client = S3Client(
        url="http://s3-url",
        session=session,
        access_key_id="key-id",
        secret_access_key="hackme",
        region="us-east-1"
    )

    # Upload str object to bucket "bucket" and key "str"
    async with client.put("bucket/str", "hello, world") as resp:
        assert resp.status == HTTPStatus.OK

    # Upload bytes object to bucket "bucket" and key "bytes"
    resp = await client.put("bucket/bytes", b"hello, world")
    assert resp.status == HTTPStatus.OK

    # Upload AsyncIterable to bucket "bucket" and key "iterable"
    async def gen():
        yield b'some bytes'

    resp = await client.put("bucket/file", gen())
    assert resp.status == HTTPStatus.OK

    # Upload file to bucket "bucket" and key "file"
    resp = await client.put_file("bucket/file", "/path_to_file")
    assert resp.status == HTTPStatus.OK

    # Get object by bucket+key
    resp = await client.get("bucket/key")
    data = await resp.read()

Bucket may be specified as subdomain or in object name:

client = S3Client(url="http://bucket.your-s3-host", ...)
resp = await client.put("key", gen())

client = S3Client(url="http://your-s3-host", ...)
resp = await client.put("bucket/key", gen())

client = S3Client(url="http://your-s3-host/bucket", ...)
resp = await client.put("key", gen())

Auth may be specified with keywords or in URL:

client = S3Client(url="http://your-s3-host", access_key_id="key_id",
                  secret_access_key="access_key", ...)

client = S3Client(url="http://key_id:access_key@your-s3-host", ...)
