使用Apache libcloud连接到softlayer对象存储

Question

Problem:

Trying to connect to Softlayer Swift Object Storage using apache libcloud and I can't get it to work. I have tried passing in different options to the provider but no matter what I pass in I get the same error. I would appreciate any and all pointers to help me resolve this issue.

Code:

from pprint import pprint
from libcloud.storage.types import Provider
from libcloud.storage.providers import get_driver

_swift = get_driver(Provider.OPENSTACK_SWIFT)
_authurl = "https://lon02.objectstorage.softlayer.net/auth/v1.0"
_user = "IBMOS<redacted>"
_key = "redacted"

driver = _swift(_user, _key,
                region='lon02',
                ex_force_auth_url=_authurl,
                ex_force_auth_version='1.0',
                ex_force_service_type='object-store',
                ex_force_service_name='cloudFiles')


#pprint(driver.__dict__)
pprint(driver.list_containers())

To answer my own question, the specific issue seen above was due to the system I was using. Once I switched to another system it proceeded even further however there is a bug I identified and filed in apache libcloud with a documented workaround inside the jira ticket here https://issues.apache.org/jira/browse/LIBCLOUD-972 .
