Data Download (GPService) using Python

I am developing a python script to download the data of feature layers from MapServer. While hitting a empty feature layer (published layer with fields but no features), the query returns just the object id.

Hitting the following Query

mapservicequery_jsondata = json.loads(urllib2.urlopen(url).read())

where

url = urltoMapserverwithLayerID+ '/'+ ("query?where=1%3D1&returnGeometry=true&returnCountOnly=false&returnIdsOnly=" + "false&outFields=*&f=pjson&token="+token)

The output in json it gives is:

{

"objectIdFieldName": "OBJECTID",

"globalIdFieldName": "",

"features": []

}

How can I get the fields (i.e. schema) of the empty feature layer downloaded?
