/*  Log all http/https requests and responses of okhttp

    This script will add HttpLoggingInterceptor at OkHttpClient, so
    the HttpLoggingInterceptor will print all requests and responses.

    This strategy does not matter if you are doing TLS Pinning bypass 

    Run with:
    frida -U -f [APP_ID] -l okhttp-logging.js --no-pause
    or
    frida --codeshare helviojunior/okhttp-logging -U -f [APP_ID] --no-pause
