So I've been setting something up on a Raspi that steals a youtube mp3 and plays it down the aux. The only problem I have is going about getting requests from users. I know what to do once I receive a URL, but I don't know how to receive it.. D'ya get me?

Ideally I'd like to just have a way for the Pi to recieve requests. I've never done anything transmission based so don't have a clue.

I'm asking here because ideally I'd like to set up a PHP page (Can be hosted on the pi itself on a LAN) with only a box to input the URL and a "send request" button.

Any help at all would be greatly appreciated.

Spoiler: sample

Client (index.html):

Code:

<!DOCTYPE html> <html> <head> <!-- import jquery and socket.io for client use --> <script src='https://cdn.socket.io/socket.io-1.2.0.js'></script> <script src='http://code.jquery.com/jquery-1.11.1.js'></script> <!-- client-side socket.io script --> <script type='text/javascript'> //'require' io() var socket=io(); //on form submit do... $('form').submit(function(){ //emit a request, which will be picked up by the server socket.emit('request',$('#url').val()); //alert client alert('request sent'); $('#url').val(''); return false; }); </script> </head> <body> <!--create div at center --> <div style='width: 300px;height: 300px;position: absolute;left: 50%;top: 50%;margin-left: -150px;margin-top: -150px;'> <!-- create input form --> <form action=''> <input id='url' autocomplete='off'/><button>Send Request</button> </form> </div> </html>

Server (index.js):

Code:

var app=require('express')(); var http=require('http').Server(app); var io=require('socket.io')(http); //feed client the proper page app.get('/',function(req,res){ res.sendFile(__dirname+'/index.html'); }); //listen for connections io.on('connection',function(socket){ //listen for request emission socket.on('request',function(url){ //execute mp3 grabbing code }); }); //tune listener to port 8080 http.listen(8080)
