Hi Alexis,

Here is a simple python example on how to use the admin api.  You will
need to get a few packages from the cheese shop (virtualenv + pip makes
this easy).

  pip install requests-aws

You will also need to set the appropriate key, secret and server for
your local instance.  If you have changed where the admin api lives in
the URI for your radosgw (/admin/ by default) you will need to update
that.  You will also need to ensure you set the appropriate 'caps' on
the radosgw for what information you are looking for.  Initially this is
done with the 'radosgw-admin caps add' command.  The current supported
caps are buckets, metadata, usage and users.  You can have either read,
write or * (both).

  radosgw-admin caps add --uid=test --caps="users=*"

The last thing you need to understand is that you have to sign each
request in the same way you would a S3 request (S3Auth in the following
example).

import requests
import logging
from awsauth import S3Auth

logging.basicConfig(level=logging.DEBUG)

aws_key = 'DFJKJDKLSsdafd321s'
secret = 'j23141kjalJLKDFDM:FDFD+dfDKJHNK'
server = 'radosgw.example.com'

url = 'https://%s/admin/user?format=json&uid=test' % server
r = requests.get(url, auth=S3Auth(aws_key, secret, server))
print r.content


This produces something that should look like this,

INFO:requests.packages.urllib3.connectionpool:Starting new HTTPS
connection (1): radosgw.example.com
DEBUG:requests.packages.urllib3.connectionpool:"GET
/admin/user?format=json&uid=test HTTP/1.1" 200 None
{"user_id":"test","display_name":"Testing","email":"","suspended":0,"max_buckets":1000,"subusers":[],"keys":[{"user":"test","access_key":"3FV6LBDJ80D3kI3I9TH8","secret_key":"z+/Rx0Osb3culGMCHL2E3Vg68gpFUSgSxcgf8BG9m"}],"swift_keys":[],"caps":[{"type":"buckets","perm":"*"},{"type":"metadata","perm":"*"},{"type":"usage","perm":"*"},{"type":"users","perm":"*"}]}

Thanks,
derek
