How to capture HTTP request / response headers with mitmproxy?

Question

I have been able to capture the HTTP(s) traffic from a smartphone and also stored this traffic using mitmdump using the command

mitmdump -w outfile

Answer 1

You can extract any header fields you need, e.g., with mitmdump and the flow object (python inline scripts). Inline scripts are documented here: https://mitmproxy.org/doc/scripting/inlinescripts.html

To extract all headers, I used the following command:

$ mitmdump -n -q -s parse_headers.py -r .mitm

The parse_headers.py inline script is as follows:

def response(context, flow):
    request_headers = [{"name": k, "value": v} for k, v in flow.request.headers]
    response_headers = [{"name": k, "value": v} for k, v in flow.response.headers]
    print request_headers
    print response_headers
