How to get data out of a Node.js http get request

Question

I\'m trying to get my function to return the http get request, however, whatever I do it seems to get lost in the ?scope?. I\'m quit new to Node.js so any help would be appr

Of course your logs return undefined : you log before the request is done. The problem isn't scope but asynchronicity.

http.request is asynchronous, that's why it takes a callback as parameter. Do what you have to do in the callback (the one you pass to response.end):

callback = function(response) {

  response.on('data', function (chunk) {
    str += chunk;
  });

  response.on('end', function () {
    console.log(req.data);
    console.log(str);
    // your code here if you want to use the results !
  });
}

var req = http.request(options, callback).end();
