Hey thanks for this, how can I send, for example a json message, through the do_GET?

Please change Listening on localhost to Listening on all interfaces or maybe Listening on 0.0.0.0, because using an empty host on HTTPServer means all interfaces, not just localhost. This has serious security implications. I know this is just a test echo server, but it would be great not to mislead users.

I noticed this fails when being accessed from fetch due to CORS errors and lacking OPTIONS. I wonder if that is an easy fix?

Good suggestions, I modified it accordingly.

I have not used this script for a long time, it is rather a template which can be adjusted as needed. If you have a solution, it could be great if you share that gist as well!

Thanks for this! Came in clutch testing an API wrapper!
