Testing setup
- Download this image file, this html file, and this python script to a local directory
-
From the directory with those files, run
python3 -m http.serverfor the HTTP server and runpython3 ws.pyfor the WebSocket server - For testing WebTransport, download webtransport_server.py and follow the instructions in there to get it running. Self-signed certificate is the easiest thing to do for https (WebTransport does not work with https://localhost, it requires https://localhost).
