Instance Method Details

#change_account(account) ⇒ Object

Change the current account while re-using the auth token.

This is usefull when you have an admin role and you’re able to HEAD other user accounts, set quotas, list files, etc.

For example:

# List current user account details
service = Fog::Storage[:openstack]
service.request :method => 'HEAD'

Would return something like:

Account:                      AUTH_1234
Date:                         Tue, 05 Mar 2013 16:50:52 GMT
X-Account-Bytes-Used:         0 (0.00 Bytes)
X-Account-Container-Count:    0
X-Account-Object-Count:       0

Now let’s change the account

service.('AUTH_3333')
service.request :method => 'HEAD'

Would return something like:

Account:                      AUTH_3333
Date:                         Tue, 05 Mar 2013 16:51:53 GMT
X-Account-Bytes-Used:         23423433
X-Account-Container-Count:    2
X-Account-Object-Count:       10

If we wan’t to go back to our original admin account:

service.

#post_set_meta_temp_url_key(key) ⇒ Object

Set the account wide Temp URL Key. This is a secret key that’s used to generate signed expiring URLs.

*** CAUTION *** changing this secret key will invalidate any expiring URLS generated with old keys.

Parameters

  • key<~String> - The new Temp URL Key

Returns

  • response<~Excon::Response>
