Node.js code not working

Following through with the Node.js tutorial, and got to the step to chain all the response.on('data') chunks together for one response. My code is here: 

/* requires all needed modules */
var http = require("http"); 

/* Makes a request to teamtreehouse's user API, and handles any errors */
function makeRequest(){
    var request = http.get("http://teamtreehouse.com/michaeldu2.json", function(response){
        var body = ""; 
        response.on('data', function(chunk){
            console.log(chunk); 
        });
        response.on('end', function(){ 
            console.log(body); 
        })
    }).on("error", function(err){
        console.log("following error occured: "  + err.message); 
    });
}

makeRequest();

However, console.log(body) comes out as just "" everytime. I tried putting a console.log inside response.on('data'), but that never gets called. Can't figure out why this is happening. I'm running this on my localhost by the way, and each step in the tutorial was working fine and I get a response object, just response.on('data') never triggers. Thanks for your help.

Hi Michael,

In October, Treehouse switched to a HTTPS protocol; this is probably what's causing your error. Look at the Teacher's Notes here to learn more. In the meantime, your code above should work if you change all http references to https — like so:

/* requires all needed modules */
var https = require("https");

/* Makes a request to teamtreehouse's user API, and handles any errors */
function makeRequest() {
    var request = https.get("https://teamtreehouse.com/michaeldu2.json", function (response) {
        var body = "";
        response.on('data', function (chunk) {
            console.log(chunk);
        });
        response.on('end', function () {
            console.log(body);
        })
    }).on("error", function (err) {
        console.log("following error occured: " + err.message);
    });
}

makeRequest();
