Unified cloud storage API for storage services.

Cloud Storage

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. 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

>>> 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>'
    }
}
