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).

const { Task } = Cu.import("resource://gre/modules/Task.jsm", {});

const { setTimeout } = require("sdk/timers");

Task.spawn(function * () {
    let item1 = yield getItem(1);
    let [item2, item3] = all([getItem(2), getItem(3)]);
    console.log(item1, item2, item3); // 1, 2, 3
}).then(function () {
    console.log('all items processed')
