python using pyshark to parse .pcap file

I have a wireshark .pcap file and i want to get all the assets (urls, ip's, pc names etc..) from this file. i tried to use some examples i found online, but i'm having some problems getting those items. i managed to find the dst and src ip address, but thats all.

this is my current code:

import pyshark

cap = pyshark.FileCapture('dor.pcap')

count = 0
for pkt in cap:
    ip_source = pkt.ip.__dict__["_all_fields"]["ip.src"]
    ip_address = pkt.ip.__dict__["_all_fields"]["ip.dst"]

This should work with your Wireshark pcap file to obtain the source and destination addresses and ports. The output could be modified (e.g., csv, dictionary) to fit your specific requirements.

Please provide more details on the other items that you would like to parse from a pcap file.

import pyshark

def network_conversation(packet):
  try:
    protocol = packet.transport_layer
    source_address = packet.ip.src
    source_port = packet[packet.transport_layer].srcport
    destination_address = packet.ip.dst
    destination_port = packet[packet.transport_layer].dstport
    return (f'{protocol} {source_address}:{source_port} --> {destination_address}:{destination_port}')
  except AttributeError as e:
    pass

capture = pyshark.FileCapture('test.pcap')
conversations = []
for packet in capture:
  results = network_conversation(packet)
  if results != None:
    conversations.append(results)

# this sorts the conversations by protocol 
# TCP and UDP
for item in sorted(conversations):
  print (item)
