Thanks for this wonderful script, there is a typo.

mitmweb -s mitmpcap.pcap

should be

mitmweb -s mitmpcap.py

@muzuiget

It just creates an empty output.pcap file
Thanks!

Checksum incorrect error in TCP and IPV4 in every request.

When I use the addon, it shows these information:
Addon error: Traceback (most recent call last):
File "c:\Program Files (x86)\mitmproxy\mitmpcap.py", line 114, in response
client_addr = list(flow.client_conn.ip_address[:2])
AttributeError: 'Client' object has no attribute 'ip_address'

How can I fix it?

Thank you very much for this addon :)
On my connection (dual stack ipv4/ipv6) it occasionally throws the following error.

Addon error: Traceback (most recent call last):
  File "mitmpcap.py", line 118, in response
    self.export_request(client_addr, server_addr, flow.request)
  File "mitmpcap.py", line 129, in export_request
    self.exporter.packets(*client_addr, *server_addr, payload)
  File "mitmpcap.py", line 59, in packets
    self.packet(src_host, src_port,
  File "mitmpcap.py", line 39, in packet
    ipv4_args.extend(map(int, dst_host.split('.')))
ValueError: invalid literal for int() with base 10: '2a02:26f0:12d::58dd:d62b'

There is a better way to create PCAP files today, see the mitmproxy document Wireshark and SSL/TLS Master Secrets.

Google SSLKEYLOGFILE for more information.

I close all the issues, and I will archive this project later.
