uasyncio web server example

[DavesCodeMusings]

As a way to learn more about using uasyncio, I created a simple "echo back" web server example as a gist

Basically, whatever gets sent in the HTTP request from a browser or from curl gets sent back as a reply. Obviously, you'll need the microcontroller connected to your network for it to work, but otherwise just copy the gist and run it.

Example output (from curl):

$ curl -v 192.168.0.37
*   Trying 192.168.0.37:80...
* Connected to 192.168.0.37 (192.168.0.37) port 80 (#0)
> GET / HTTP/1.1
> Host: 192.168.0.37
> User-Agent: curl/7.83.1
> Accept: */*
>
* Mark bundle as not supporting multiuse
< HTTP/1.1 200 OK text/plain

< Connection: close

GET / HTTP/1.1
Host: 192.168.0.37
User-Agent: curl/7.83.1
Accept: */*

* Closing connection 0

I created this using MicroPython 1.19.1 on an ESP8266. Hopefully this will be useful to others wanting to get started with uasyncio. And if you see any glaring error in the gist, please let me know and I'll update it.
