Intercept and manipulate HTTPs traffic with Python and mitmproxy

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This Gist is created in 2014, and it's highliy outdated now, according to one of mitmproxy's manjor contributor (check his comment below).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.

Serilog (C#): How to get current MethodName, FileName/Path and LineNumber without reflection

Serilog (C#): How to get the current MethodName, FileName/Path and LineNumber without reflection

This is a simple setup for reflectionless logging with serilog using caller information (and a single static class).

See also https://stackoverflow.com/a/46905798

Log.cs

Create your own Log.cs in your Root-Namespace (you can use the class below).

This class is required to detect where the call is coming from; it uses Caller-Information to speed up the program execution, because the attributes are resolved at compile-time.
