Redirect API calls from a live URL to localhost when path signatures are different

Introduction

When developing a new version of an API that's meant to replace an existing one, you may need to test the new API using the live URL to ensure proper functionality. However, if the path signatures of the new API are different from the existing one, using /etc/hosts to redirect the calls won't be sufficient. In this article, we will demonstrate how to use mitmproxy to redirect API calls from the live URL to your localhost, allowing you to test the new API with different path signatures.

Prerequisites

Before we begin, make sure you have the following software installed:

	const ffmpeg = require('fluent-ffmpeg');
	const path = require('path');

	const m3u8Url = 'https://stream.mux.com/playback_id.m3u8';

	const outputPath = path.join(__dirname, 'output.mp4');

	ffmpeg(m3u8Url)
	.outputOptions([
	'-c copy',

	source ./send_email.sh

	# Class method
	receiver.method(method_name)
	elsif receiver.method_defined?(method_name) \|\| receiver.private_method_defined?(method_name)
	# Instance method
	receiver.instance_method(method_name)

	const crypto = require("crypto");

	const secretAccessKey = ""; // AWS_ACCESS_KEY_SECRET
	const regionName = "us-east-1";

	# wait for a program to start listening on a PORT ($1)
	wait_for_port() {
	local PORT=$1

	nc -z localhost $PORT && echo "port $PORT is ready" && return
