Question

所以我有一些OpenStack设备，我厌倦了与仪表板的斗争，所以我想在python中编写自己的自动化。然而，我几乎没有弄湿脚，我遇到了问题。

代码：

from keystoneclient.auth.identity import v2
from keystoneclient import session
from novaclient.client import Client

auth = v2.Password(auth_url='http://10.0.0.1:5000/v2.0/', username='foo.bla-admin',
    password='hunter2', tenant_name='foo.bla')
sess = session.Session(auth=auth)
nova = Client(2, sess)

print nova.authenticate()

错误：

Traceback (most recent call last):
  File "test.py", line 13, in <module>
    print nova.authenticate()
  File "/usr/lib/python2.6/site-packages/novaclient/client.py", line 169, in wrapper
    return f(self, *args, **kwargs)
  File "/usr/lib/python2.6/site-packages/novaclient/v1_1/client.py", line 239, in authenticate
    self.client.authenticate()
  File "/usr/lib/python2.6/site-packages/novaclient/client.py", line 561, in authenticate
    magic_tuple = netutils.urlsplit(self.auth_url)
  File "/usr/lib/python2.6/site-packages/oslo_utils/netutils.py", line 228, in urlsplit
    url, scheme, allow_fragments)
  File "/usr/lib64/python2.6/urlparse.py", line 171, in urlsplit
    i = url.find(':')
AttributeError: 'NoneType' object has no attribute 'find'

所有的连接信息都来自控制器上的环境变量，所以我知道这应该是正确的，我已经尝试用项目ID交换租户名称，但仍然没有乐趣。我不知道为什么它会在urlparse中一直抛出这个错误，或者为什么它似乎在使用1.1客户端，即使我已经指定了v2。

另外，无论我是否使用keystone auth，我都会得到同样的错误，我认为这是我在控制器的rc文件中OS_AUTH_STRATEGY=keystone以来最好的选择。

最后，如果它有用，在导入过程中我也会收到以下弃用警告：

您的代码中存在一些错误。仔细看看api documentation。如果你打电话：

nova = Client(2, sess)

然后sess没有获得session关键字参数的传递。你想要：

nova = Client(2, session=sess)

而且您不需要致电nova.authenticate()。
