使用OpenStack API时未经授权的错误无法从keystone获取身份验证令牌

标签: python api rest openstack keystone

我想使用RESTful API,例如

https://nova.rc.nectar.org.au:8774/v1.1/1f283209946f428998e8d3930bb038d1

但无法获取身份验证令牌。

我尝试了以下命令来获取它(我没有管理员权限):

curl -d '{"auth":{"passwordCredentials":{"username": "miranda.zhang", "password": "mypass"}}}' -H "Content-type: application/json"  https://keystone.rc.nectar.org.au:5000/v2.0/tokens

但仍然得到

{"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}

我还看过python-keystoneclient 我试着安装它

python setup.py install

但它返回错误

Traceback (most recent call last):
  File "setup.py", line 18, in <module>
    import setuptools
ImportError: No module named setuptools

这是openrc.sh file generated by my cloud provider,似乎没什么帮助。

#!/bin/bash

# With the addition of Keystone, to use an openstack cloud you should
# authenticate against keystone, which returns a **Token** and **Service
# Catalog**.  The catalog contains the endpoint for all services the
# user/tenant has access to - including nova, glance, keystone, swift.
#
# *NOTE*: Using the 2.0 *auth api* does not mean that compute api is 2.0.  We
# will use the 1.1 *compute api*
export OS_AUTH_URL=https://keystone.rc.nectar.org.au:5000/v2.0/

# With the addition of Keystone we have standardized on the term **tenant**
# as the entity that owns the resources.
export OS_TENANT_ID=1f283209946f428998e8d3930bb038d1
export OS_TENANT_NAME="pt-1114"

# In addition to the owning entity (tenant), openstack stores the entity
# performing the action as the **user**.
export OS_USERNAME="miranda.zhang"

# With Keystone you pass the keystone password.
echo "Please enter your OpenStack Password: "
read -sr OS_PASSWORD_INPUT
export OS_PASSWORD=$OS_PASSWORD_INPUT

  4. 我尝试了Barak的建议,包括租户名称,但仍然得到以下内容:

    HTTP/1.1 401 Unauthorized
    Vary: X-Auth-Token
    Content-Type: application/json
    Content-Length: 114
    Date: Sun, 29 Dec 2013 08:54:28 GMT
    
    {"error": {"message": "The request you have made requires authentication.", "code": 401, "title": "Unauthorized"}}
    

    我已经在Barak的帮助下安装了keystone客户端:

    sudo apt-get install python-setuptools
    sudo easy_install pip
    sudo pip install python-keystoneclient
    

    但是像这样使用它:

    keystone --os-tenant-name pt-1114 --os-username USERNAME --os-password PASSWORD --os-auth-url https://keystone.rc.nectar.org.au:5000/v2.0/tokens -os-identity-api-version 2.0 --debug token-get
    

    我收到了此错误,而token-get显然是一个有效选项。

    usage: keystone [--version] [--timeout <seconds>]
                    [--os-username <auth-user-name>]
                    [--os-password <auth-password>]
                    [--os-tenant-name <auth-tenant-name>]

    我刚刚意识到我登录门户网站的现有密码不能用作

      

    要使用OpenStack API访问Nectar Cloud,您需要这样做   生成密码。通过这样做任何现有的密码将是   忘记了。要生成新密码,请单击“重置密码”按钮。

    问题解决了。

答案 0 :(得分:2)

您缺少json块中的租户名称。这是一个有效的卷曲请求:

curl -i 'http://192.168.9.70:5000/v2.0/tokens' -X POST -H "Content-Type: application/json" -H "Accept: application/json" -H "User-Agent: python-novaclient" -d '{"auth": {"tenantName": "TENANT", "passwordCredentials": {"username": "USERNAME", "password": "PASSWORD"}}}'

我建议您使用pip安装keystone客户端:

sudo apt-get install pip
sudo pip install python-keystoneclient

然后使用'--debug'选项运行任何keystone命令以查看实际的json。

答案 1 :(得分:0)

请参阅以下代码作为示例:

  
      
  1. 使用curl命令:
  2.   
curl http://<controller_ip>:5000/v2.0/tokens \
-X POST \
-d '{"auth":{"tenantName":"demo", "passwordCredentials":{"username":"demo", "password":"*****"}}}' \
-H "Content-type: application/json" | python -m json.tool

这里 python -m json.tool 用于以json可读格式打印输出。

  
      
  1. 使用Python API
  2.   
url="<controller_ip>:5000"
params='{"auth":{"tenantName":"demo", "passwordCredentials":{"username":"demo", "password":"*****"}}}'
headers={"Content-Type": "application/json"}
conn=httplib.HTTPConnection(url)
conn.request("POST", "/v2.0/tokens", params,headers)
response=conn.getresponse()
data=response.read()
verify_services=json.loads(data)
auth_token=verify_services ['access']['token']['id']
print("Token=%s\n" % auth_token)
