Because you are passing values as query parameters and not URL parameter from client.

Server side

app.get('/download', function(req, res) {

  var foo  = req.query.foo;
  var xxx = req.query.xxx;

  console.log(foo)
  console.log(xxx)

  //res.download(__dirname + '/uploads/google' + id  +'.png');
});
