Request Parameter in express js

I am using express.js and I am trying to fetch the request parameter using the following code.

app.configure(function () {
  app.use(express.static(__dirname + '/public'));
});

app.get('/', function (req, res) {
  console.log(req.params[0]);
  console.log(req.params.id);
  res.render('/public/index.html');
});

My url looks like this.

http://localhost:8080/?id=34.

I am not getting the request parameter. I tried all possibilities.
