Express - handling json response

Question

I have two node servers (A + B) and both use Expressjs.

From one I use Request (https://github.com/mikeal/request) to make a GET request to the other:

//A server
app.get('/:id', function(req, res) {
  request('http://localhost:8080/api/' + req.params.id, function (error, response, body) {
    console.log(body);
  })
});

and the other is:

//B server
app.get('/api/:id', function(req, res) {
  res.json(200, {url: "http://www.google.co.uk"});  
});

As you can see, A is making a request to B and B returns a json result. However, I'm not sure how to deal with the response in A. console.log(body) prints the complete json but how can I access the url sent from B?

I have tried body.url but no luck

The JSON result is a string. You must first parse it via JSON.parse, prior to accessing it like an object:

var url = JSON.parse(body).url;
