novaclient身份验证期间的urlsplit错误

novaclient openstack python

Sammitch · 技术社区 · 9 年前

所以我有一些OpenStack设备,我厌倦了与仪表板的斗争,所以我想用python编写自己的自动化。然而,我连脚都没湿,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,我已经尝试将租户名称与项目ID交换,但仍然没有任何乐趣。我不知道为什么它会在urlparse中一直抛出这个错误,也不知道为什么即使我指定了v2,它仍然使用1.1客户端。

此外,无论我是否使用keystone身份验证,我都会遇到同样的错误,我认为这是我自 OS_AUTH_STRATEGY=keystone 在控制器的rc文件中。

最后,如果有帮助,在导入过程中,我还会收到以下弃用警告:

代码中有一些错误。请仔细查看 api documentation 。如果您拨打:

nova = Client(2, sess)

然后 sess 无法获得 session 关键字参数。您需要:

nova = Client(2, session=sess)

你不需要打电话 nova.authenticate() .
