Is there a simple open source http-server for Arduino Mega?

Question

Arduino

We need a simple http server to organize the interaction of Arduino with external services via http. Maybe someone knows these?

Answer 1

First, you need Ethernet sheeld w5100, Ethernet.h library for it or w5500, Ethernet2.h library for it.
In the examples for the library there is a simple server.
If you need to process GET requests, parse by variables, then you need WebServer.h

Answer 2

Look at https://habr.com/ru/post/382177/ and
https://hi-lab.ru/arduino-mega-server
, maybe what you want is already implemented there. Plus, somewhere there was an article that, as part of this project, the library for the Ethernet Shield was finalized, with a more stable implementation of the work, an example is somewhere on their website
