Using Pyshark to pair key and value from JSON packet

由 随声附和 提交于 2020-08-11 01:43:20
问题 I am trying to parse a PCAP file using Pyshark. Some of the packets have JSON in them and I am trying to print them out with matching key:value. This is what I have at the moment for testing: import pyshark packets = pyshark.FileCapture('cap.pcapng') pack = packets[1] #get the packet that has JSON print(pack.json.get_field_value('app') When doing this, I get None printed. If I print the entire JSON layer I get data like this: Object Member Key: anonymousId String value: f268204c-5719-43ce

Count the number of packets with pyshark

问题 In this code with pyshark import pyshark cap = pyshark.FileCapture(filename) i = 0 for idx, packet in enumerate(cap): i += 1 print i print len(cap._packets) i and len(cap._packets) give two different results. Why is that? 回答1: A look at the source code reveals that _packets is a list containing packets and is only used internally: When iterating through a FileCapture object with keep_packets = True packets are getting added to this list. To get access to all packets in a FileCapture object

问题 I am using Pyshark to parse Wireshark sniffer log, and I used exported Json format file (based on pcapny file) to find field names when use 'get_field_value' function to retrieve field value. For example, in order to get BSSID value: In Json format file, this info is displayed as "wlan.bssid": "11:22:33:44:55:66" Then I could use: value = packet['wlan'].get_field_value('bssid') Result is expected: value == '11:22:33:44:55:66' For this case, it is working fine. But I encounter an issue with
