創建中子客戶端時出錯

-1

我是OpenStack環境的新手，我正在嘗試使用Openstack API。我在執行基本腳本時使用neutron API列出網絡時出現以下錯誤。創建中子客戶端時出錯

腳本

#!/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()

錯誤

neutronConnection.list_networks() 
    File "/usr/lib/python2.6/site-packages/neutronclient/v2_0/client.py", line 98, in with_params 
    ret = self.function(instance, *args, **kwargs)

如果我確實從命令行執行neutron net-list ..它工作得很好。 – 2014-10-30 15:12:00

的錯誤表示存在與您在OS_TENANT_NAME環境變量傳遞承租人的名稱問題。它的值是'ESS'，或者沒有這個名字的租戶，或者用戶無權訪問它。

如果您能夠運行neutron CLI，請打印出您在那裏使用的環境變量並將其複製到您的代碼中。
