使用python SDK v2进行Openstack身份验证
提问于 2018-09-11 07:12:27
我是这里的OpenStack新手。
我尝试使用REST API来自动化我的openstack工作。我可以使用以下命令成功我的帐户并从curl获取令牌：
export AUTH_URL="https://my_url:5000/v2.0/tokens"
curl -v -X POST $AUTH_URL -d '{"auth":{"passwordCredentials":{"username": "myusername", "password":"myuser_password"}, "tenantId":"my_tenant_id"}}' -H 'Content-type: application/json' | python -m json.tool但是，当我尝试在下面的代码中使用Pyton时，它给出了这个错误
Traceback (most recent call last):
File "./test.py", line 10, in <module>
keystone = ksclient.Client(auth_url=auth_url, username=user_name, password=user_pwd, tenant_name=tenant_name)

_("Authorization Failed: %s") % e)
keystoneauth1.exceptions.auth.AuthorizationFailure: Authorization Failed: The resource could not be found. (HTTP 404) (Request-ID: 我的python代码如下：
#!/usr/bin/env python
import keystoneclient.v2_0.client as ksclient
auth_url = "https://my_url:5000/v2.0/tokens"
user_name = "myusername"
user_pwd = "myuser_password"
tenant_name = "my_tenant_id"
keystone = ksclient.Client(auth_url=auth_url, username=user_name, password=user_pwd, tenant_name=tenant_name)
print keystone.auth_token你能看看我的代码，看看为什么python代码不能工作吗？
谢谢!

在使用客户端进行身份验证时，应仅提供https://my_url:5000/v2.0作为路径。
有关详细信息，请参阅this文档。
您也可以尝试这样的操作。
from keystoneauth1 import loading
from keystoneauth1 import session
from keystoneclient import client as keystoneclient
auth_url = 'https://my_url:5000'
user = '<user>'
password = '<password>'
tenant = '<tenant>'
loader = loading.get_plugin_loader('password')
keystone_auth = \
loader.load_from_options(
auth_url=auth_url,
username=user,
password=password,
user_domain_name=tenant
)
keystone_session = session.Session(
auth=keystone_auth,
verify=False
)
print(keystone_session.get_token())请记住，Keystone Openstack API已被弃用，并在最新版本的V2中被删除。如果可能，我建议尽快转移到V3应用程序接口。
