Feature request: make web_microphone_websocket work outside localhost

[comodoro]

The web_microphone_websocket example works for localhost, but on a domain there were CORS errors from the socket.io code, e.g. Chrome:

Access to XMLHttpRequest at 'https://example.com:4000/socket.io/?EIO=3&transport=polling&t=Nu-iT4E' from origin 'https://example.com.cz:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Several recipes from SO and the socket.io docs did not work, perhaps someone with better JS knowledge might help.

Hi Comodoro are you still looking for this

[comodoro]

Yes, my attempts were unsuccessful as I have zero experience with socket.io and rusty with JavaScript.

Try this in the server.js:

const app = http.createServer(function (req, res) {
	const headers = {
		'Access-Control-Allow-Origin': '*',
		'Access-Control-Max-Age': 2592000, // 30 days
		/** add other headers as per requirement */
	};
	res.writeHead(200, headers);
	res.write('STT');
	res.end();
});

const io = socketIO(app, {});
io.set('origins', '*:*');
