Python Openstacksdk - KeyError: 'owner' 尝试使用 id 获取服务器详细信息时

分类：编程问答

如何解决Python Openstacksdk - KeyError: 'owner' 尝试使用 id 获取服务器详细信息时

我目前正在尝试使用 compute.get_server(id) 通过 id 检索服务器。我从日志中可以看到 API 已完成并返回我通常使用 openstack cli 获取的所有字段（或使用 compute.get_servers() 获取所有服务器）

这是我收到的：

Traceback (most recent call last):
  File "C:\Users\myuser\Documents\myproj\venv\Lib\site-packages\openstack\resource.py",line 158,in __get__
    value = attributes[self.name]
  File "C:\Users\myuser\Documents\myproj\venv\Lib\site-packages\openstack\resource.py",line 253,in __getitem__
    return self.attributes[key]
KeyError: 'owner'


During handling of the above exception,another exception occurred:

在我的代码中抛出异常的地方：

servers_manager.py


def get_server(id,project):
   
    conn = connection_controller.connect(project)
    server = conn.compute.get_server(id)
    return server

我使用的连接方式：

connection_controller.py


def connect(project_name):
    return conn_manager.create_connection(conf.OPENSTACK_AUTH_URL,conf.OPENSTACK_REGION,project_name,conf.OPENSTACK_USER,conf.OPENSTACK_PASSWORD,conf.OPENSTACK_SSL_VERIFY)

connection_manager.py

def create_connection(auth_url,region,username,password,verify):
    return openstack.connect(
        auth_url=auth_url,project_name=project_name,username=username,password=password,region_name=region,verify=verify,cacert="ca.crt"
    )
