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。

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。

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。

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。

请参阅以下代码作为示例:
- 使用curl命令:
醇>
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。
- 使用Python API
醇>
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)
