#["LÓGICA DE PROGRAMAÇÃO" É BOBAGEM, e explicarei porquê.]

Se preparem que o texto é longo.

Várias vezes chegam novatos aqui perguntando como começar, e a galera diz "estuda lógica primeiro, depois vai pra linguagem X". Vivo dizendo que é bobagem. Ontem, em particular, falei isso, e vieram várias pessoas por inbox me perguntar porquê (e uma pra me xingar, achando que falei por arrogância).

Pra facilitar, eu vou escrever uma boa explicação de porquê "lógica de programação" é furada, doa a quem doer, e postar na APDA e no fórum da EnergyLabs (para futuras referências, porque esse assunto vai voltar, ctz).

Intercepts HTTPs Traffic with Python & mitmproxy

Introduction

Modern applications usually make use of back-end API servers to provide their services. With a non-transparent HTTPs proxy, which intercepts the communication between clients and servers (aka the man-in-the-middle scheme), you can easily manipulate both API requests and responses.

This manual helps you create your own proxy with Python and mitmproxy/libmproxy. Mitmproxy ships with both a standalone command-line tool (mitmproxy) and a Python library (libmproxy).
