创建中子客户端时出错

-1

我是OpenStack环境的新手，我正在尝试使用Openstack API。我在执行基本脚本时使用neutron API列出网络时出现以下错误。创建中子客户端时出错

脚本

#!/usr/bin/env python 
from neutronclient.v2_0 import client as neutronClient 
import os 

neutronConnection = neutronClient.Client(
    username=os.environ['OS_USERNAME'], 
    password=os.environ['OS_PASSWORD'], 
    tenant_name=os.environ['OS_TENANT_NAME'], 
    auth_url=os.environ['OS_AUTH_URL'] 
    ) 
print neutronConnection 
neutronConnection.format = 'json' 
neutronConnection.list_networks()

错误

neutronConnection.list_networks()

    ret = self.function(instance, *args, **kwargs)

如果我确实从命令行执行neutron net-list ..它工作得很好。 – 2014-10-30 15:12:00

的错误表示存在与您在OS_TENANT_NAME环境变量传递承租人的名称问题。它的值是'ESS'，或者没有这个名字的租户，或者用户无权访问它。

如果您能够运行neutron CLI，请打印出您在那里使用的环境变量并将其复制到您的代码中。
