Using scapy (scapy latest version 2.4.3, address: https://scapy.net/) capture card flow (purpose is to grab the request and response) of the specified application, at the time of parsing found very difficult to handle, simple situation is good, but in the case of using gzip compression, often at this time also use chunked for block transmission, in this case the parsing is bad to did, have had a similar experience of the great god, comment, thank you ~ ~ ~
Or there are other ways to grab application request and response, can also,
Special note: scapy, not scrapy, both are different,
