statusCode 404 when requesting user name in node.js

//Problem: We need a simple way to look at a user's badge count and javascript points.
//Solution: Use Node.js to connect to treehouse's API to get profile information to print out.

var http = require("http"), user = 'Chalkley';

function printMessage(username, badgeCount, points){
  var message = username + ' has ' + badgeCount + ' total badges and ' + points + ' points in JavaScript.';
  console.log(message);
}

//Connect to the API URL (https://teamtreehouse.com/username.json)
var request = http.get('http://teamtreehouse.com/' + user + '.json', function(response) {
  console.log(response.statusCode);
  //Read the data
  //Parse the data
  //Print the data
});
