This is a mitmproxy addon script, it exports traffic to PCAP file, so you can view the decoded HTTPS or HTTP/2 traffic in other programs.
Use as addon for mitmproxy/mitmweb/mitmdump command:
mitmweb -s mitmpcap.py
By default, it exports to filename output.pcap.
Edit the mitmpcap.py file, change the File class argument at the end of file:
addons = [Addon(lambda: File('output.pcap'))]
You also can pipe the PCAP data to other program, use the Pipe class:
addons = [Addon(lambda: Pipe('weer -'))]
This will start Weer as child process to receive the PCAP data.
