API Mirror

A very simple testing utility that takes API calls to any endpoint, printing and returning the headers and body (if any). Originally used to test the proxy function of an API Gateway under development.

If you don't need a local service, you can use the following URI to access a hosted version of API Mirror: https://api-mirror.herokuapp.com/

Getting Started

Prerequisites

Ensure you have Python 3 installed, then run pip3 install -r requirements.txt. It is recommended to use a virtual environment.

Running

To get up and running, simply clone the repo, ensure you have the prerequisites listed below installed, and then run python3 run.py.

The port(s) can be set by either changing the PORTS value in config.py, or by setting the API_MIRROR_PORTS environment variable. For example:

API_MIRROR_PORTS=8010 python3 run.py

Note: Multiple ports can be specified with a comma-separated list. This spawns a thread for each port.

Example Usage

Once running, any calls you make to the given host and port will be mirrored back.
