Here is a little utility I’ve worked up while working with the Openstack Keystone code.

To extract the token out of the JSON, use the following pyton script

#!/usr/bin/python

from sys import stdin
import json
print json.load(stdin)['access']['token']['id']

Which I save in ~/bin/extract_keystone_id.py

Here’s the Curl to fetch a token from Keystone, assuming you ‘ve loaded up the sample data from the unit tests:

curl -v   -H "Content-Type:application/json"  -s  -H "Accept:applicaton/json"  -d '{"auth":{"passwordCredentials":{"userId":"foo", "password":"foo2"} ,"tenantName":"bar"}}'   -X POST  http://0.0.0.0:35357/v2.0/tokens  | ~/bin/extract_keystone_id.py
