Libcloud-serviceCatalog为空，但OpenStack列出了服务

我正在尝试使用libcloud for OpenStack运行一些测试，但是遇到了无法找到指定端点的问题。当我运行此代码时：

from libcloud.compute.types import Provider
from libcloud.compute.providers import get_driver

import libcloud.security

libcloud.security.VERIFY_SSL_CERT = False

OpenStack = get_driver(Provider.OPENSTACK)

driver = OpenStack(
'admin', 'password',
ex_force_auth_url='http://controller:5000',
ex_force_auth_version='2.0_password'
)

driver.list_images()

我得到这个错误：

Traceback (most recent call last):
  File "my_script.py", line 25, in <module>
    driver.list_images()
  File "/usr/local/lib/python2.7/dist-packages/libcloud/compute/drivers/openstack.py", line 279, in list_images
    self.connection.request('/images/detail').object, ex_only_active)
  File "/usr/local/lib/python2.7/dist-packages/libcloud/common/openstack.py", line 202, in request
    raw=raw)
  File "/usr/local/lib/python2.7/dist-packages/libcloud/common/base.py", line 709, in request
    action = self.morph_action_hook(action)
  File "/usr/local/lib/python2.7/dist-packages/libcloud/common/openstack.py", line 269, in morph_action_hook
    self._populate_hosts_and_request_paths()
  File "/usr/local/lib/python2.7/dist-packages/libcloud/common/openstack.py", line 313, in _populate_hosts_and_request_paths
    url = self._ex_force_base_url or self.get_endpoint()
  File "/usr/local/lib/python2.7/dist-packages/libcloud/common/openstack.py", line 254, in get_endpoint
    region=service_region)
  File "/usr/local/lib/python2.7/dist-packages/libcloud/common/openstack_identity.py", line 278, in get_endpoint
    raise LibcloudError('Could not find specified endpoint')
libcloud.common.types.LibcloudError: <LibcloudError in None 'Could not find specified endpoint'>

但当我运行

openstack catalog list

命令时，我得到以下结果：

我如何让libcloud从openstack中识别我的服务目录，因为它看起来还可以，但没有被提取？已尝试使用ex_force_service_类型、ex_force_service_名称、ex_force_service_区域，但结果相同。使用ex_force_auth_令牌和ex_force_base_url会导致404错误

谢谢

原来这是keystone（身份验证）版本的问题。有必要使用

ex_force_auth_version='3.x_password'

而不是

ex_force_auth_version='2.0_password'

OpenStack的libcloud文档中没有记录：

还必须包括

ex_tenant_name='admin'

---

在我的情况下，让它工作。奇怪的是，使用v2进行auth实际上运行auth fine（我得到了一条错误的凭据消息），但不返回目录列表。只有v3能做到这一点。任何人都可以解释为什么会发生这种情况？

如果您使用的是OpenStack云，您可能希望查看Shade而不是libcloud。很容易在没有解释的情况下否决

ex_tenant_name='admin'
