# define API options
options = {"url": "http://hosted.app/api/packets", "token": "supersecretusertoken"}
 
# create parent function with passed in arguments
def customAction(options):
  # uploadPacket function has access to the options object because they are 'closed' in the nested function
  def uploadPacket(packet):
    # upload packet, using passed arguments
    headers = {'content-type': 'application/json'}
    r = requests.post(options["url"], data=json.dumps(packet,options["token"]), headers=headers)
  return uploadPacket
  
sniff(prn=customAction(options))
