from datetime import *
from requests_toolbelt.utils import dump
from awsauth import S3Auth

1. host = 'yuliyangdebugwebjewel.tunnel.qydev.com'
   #host = 'yuliyangdebugweb68.tunnel.qydev.com'
   #host = '10.254.9.20:7480'
   host = '10.254.3.68:7480' #ceph03
   #host = '127.0.0.1:7480' #ceph01
   logging.basicConfig(level=logging.DEBUG)
   access_key = 'date2'
   secret_key = 'date2'
   cmd = '/%s' % '{:%m_%d.%H_%M_%S}'.format(datetime.now())
   #cmd = '/%s' % '{:%m_%d.%H_%M_%S}'.format(datetime.now() -
   timedelta(hours=16))
   url = 'http://%s%s' % (host,cmd)
   response = requests.put(url,auth=S3Auth(access_key,
   secret_key,service_url=host))

data = dump.dump_all(response)
print(data.decode('utf-8'))

and it's output
