Using the scapy 'prn' argument, pass multiple arguments along with packet in a sniff(), s(), or sr() function.

scapy-multiple-arguments.py

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

Thanks a lot, man!

Very clever solution, thanks a lot!
