You can create a "Quick Share link" by generating a "pre-signed" URL using boto3 or another Python client library for S3-compatible object storage services.

With boto3, you first need to configure your session:

import os
import boto3
from botocore.client import Config

session = boto3.session.Session()
key = os.getenv('SPACES_KEY')
secret = os.getenv('SPACES_SECRET')

client = session.client('s3',
                        region_name='nyc3',
                        endpoint_url='https://nyc3.digitaloceanspaces.com',
                        aws_access_key_id=key,
                        aws_secret_access_key=secret)

Then you can generate a functioning pre-signed url using:

url = client.generate_presigned_url(ClientMethod='get_object', 
                                    Params={'Bucket': 'my-space',
                                            'Key': 'my-file'},
                                    ExpiresIn=300)

Note the ExpiresIn argument. By default, pre-signed URLs will expire in an hour (3600 seconds). This example sets it to expire in 5 minutes. See the boto3 docs for more info.
