I wanted to see how easy it was to download Rdio songs as you listen to them, turns out its just as easy as I though.

Rdio Proxy

var http = require('http'),
    url = require('url'),
    fs = require('fs');

var port = 9000;

var httpServer = http.createServer(function(request, response) {
  var parsedUrl = url.parse(request.url);
  var requestData;
  var requestOpts = {
    headers: request.headers,
    hostname: request.headers.host,
    method: request.method,
    path: parsedUrl.path
  };

  var mp3FileName = 'temp-mp3-file.mp3';
  var mp3File = null;

  var proxy = http.request(requestOpts, function(res) {
    console.log(res);
    // Check to see if this is an mp3 file
    // TODO: verify its from rdio and not something random
    if (parsedUrl.path.indexOf('.mp3') !== -1) {
      console.log('FOUND MP3 FILE!!!');

      mp3File = new Buffer('');
    }

    res.on('data', function(chunk) {
      if (mp3File) {
        mp3File = Buffer.concat([mp3File, chunk]);
      }

      response.write(chunk, 'binary');
    });

    res.on('end', function() {
      if (mp3File) {
        fs.writeFile('./mp3/' + mp3FileName, mp3File, function(err) {
          if (err) {
            return console.log('Error writing file', err);
          }
          
          console.log('FINISHED GETTING MP3 FILE');
        });

        mp3File = null;
      }

      response.end();
    });

    res.on('error', function(err) {
      console.log('ERROR SOMEWHERE');
    });

    response.writeHead(res.statusCode, res.headers);
  });

  request.on('data', function(chunk) {
    requestData = requestData + chunk;

    proxy.write(chunk, 'binary');
  });

  request.on('end', function() {
    proxy.end();
  });

  request.on('error', function(err) {
    console.log('Error');
  });

});

httpServer.listen(port, function() {
  console.log('HTTP Proxy Server is listening on port: ' + port);
});
