Cloud Storage_ is a Python +3.5 package which creates a unified API for the cloud storage services: Amazon Simple Storage Service (S3), Microsoft Azure Storage, Minio Cloud Storage, Rackspace Cloud Files, Google Cloud Storage, and the Local File System.

Cloud Storage is inspired by Apache Libcloud <https://libcloud.apache.org/>_. Advantages to Apache Libcloud Storage are:

• Full Python 3 support.
• Generate temporary signed URLs for downloading and uploading files.
• Support for request and response headers like Content-Disposition.
• Pythonic! Iterate through all blobs in containers and all containers in storage using respective objects.

Usage

.. code-block:: python

>>> from cloudstorage.drivers.amazon import S3Driver
>>> storage = S3Driver(key='<my-aws-access-key-id>', secret='<my-aws-secret-access-key>')

>>> container = storage.create_container('avatars')
>>> container.cdn_url
'https://avatars.s3.amazonaws.com/'

>>> avatar_blob = container.upload_blob('/path/my-avatar.png')
>>> avatar_blob.cdn_url
'https://s3.amazonaws.com/avatars/my-avatar.png'

>>> avatar_blob.generate_download_url(expires=3600)
'https://avatars.s3.amazonaws.com/my-avatar.png?'
'AWSAccessKeyId=<my-aws-access-key-id>'
'&Signature=<generated-signature>'
'&Expires=1491849102'

>>> container.generate_upload_url('user-1-avatar.png', expires=3600)
{
    'url': 'https://avatars.s3.amazonaws.com/',
    'fields': {
        'key': 'user-1-avatar.png',
        'AWSAccessKeyId': '<my-aws-access-key-id>',
        'policy': '<generated-policy>',
        'signature': '<generated-signature>'
    }
}
