GoogleStorage Class

Properties   Methods   Events   Configuration Settings   Errors  

The GoogleStorage class implements the Google Storage for Developers API.

Syntax

class ipworkscloud.GoogleStorage

Remarks

GoogleStorage allows you to easily manage storing and retrieving files using the Google Storage for Developers service.

Before using the class you must have a valid Google Storage account.

Once you have a valid Google Storage account you can start creating buckets in your account using create_bucket. The buckets are place holders for your objects allowing you to access them by http URLs. You can then add objects to any of your buckets using create_object.

There are other methods such as list_buckets, list_objects, get_object, delete_object etc. that further enable you to manage your Google Storage data store.

This class supports authentication via OAuth 2.0. First, perform OAuth authentication using the OAuth class or a separate process. Once complete you should have an authorization string which looks like:

Bearer ya29.AHES6ZSZEJzATdZYjeihDn5W-VrXSsxEZu5p0pclxGdKKQ
Assign this value to the authorization property before attempting any operations. Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

When authenticating via OAuth the project_id property is also required.

Alternatively, this service also supports authenticating by setting the AccessKey and SecretKey configuration settings.
