First of all, I’m a coding and linux newbie, so forgive me for what I’m about to ask you.
I’m using Volumio on a RPi to play webradio in my living room. Most of the time I listen to the same stream, but I occasionally need to change stream, stop play back and change volume.
Since I don’t need most of the controls and features of the Volumio web interface, I’ve been looking into controlling playback and volume with REST API, but I was wondering if you guys have a tip for best (or better) practice.
At the moment all REST API calls are done via a HTML page, uploaded on an remote webserver, like this:
<iframe style="display: none;" height="64px" width="64px" src="" name="iframe_a"></iframe> <a href="http://volumio.local/api/v1/commands/?cmd=play&N=3" target="iframe_a"> <img src="DRP4.png" width=64></a>
This is code-wise really ugly, but that’s where my skills are at. And it works well - the delay is close to unnoticeable. But my phone isn’t happy about the IFRAME, and I reckon that Websocket IO overall would be a more elegant solution.
I’ve read the docs at volumio.github.io/docs/API/WebSocket_APIs.html but I need a more thorough and basic explanation - I’m at basic html-level.
How would I go about making a HTML page using Websocket to control playback? Or am I better off taking another approach?
Thanks in advance for any input.
