Profiles have been moved, Course needs to be updated

If you want to do this course on May 2016, you may come across some problems such as trying to get the profiles. This profiles have been moved by treehouse to https protocol, SO I added my solution to it, so you can keep working on node

I just launched the workspace associated with this video:

var EventEmitter = require("events").EventEmitter;
var https = require("https");
var http = require("http");
var util = require("util");

/**
 * An EventEmitter to get a Treehouse students profile.
 * @param username
 * @constructor
 */
function Profile(username) {

    EventEmitter.call(this);

    var profileEmitter = this;

    //Connect to the API URL (https://teamtreehouse.com/username.json)
    var request = https.get("https://teamtreehouse.com/" + username + ".json", function(response) {
        var body = "";

        if (response.statusCode !== 200) {
            request.abort();
            //Status Code Error
            profileEmitter.emit("error", new Error("There was an error getting the profile for " + username + ". (" + http.STATUS_CODES[response.statusCode] + ")"));
        }

        //Read the data
        response.on('data', function (chunk) {
            body += chunk;
            profileEmitter.emit("data", chunk);
        });

        response.on('end', function () {
            if(response.statusCode === 200) {
                try {
                    //Parse the data
                    var profile = JSON.parse(body);
                    profileEmitter.emit("end", profile);
                } catch (error) {
                    profileEmitter.emit("error", error);
                }
            }
        }).on("error", function(error){
            profileEmitter.emit("error", error);
        });
    });
}

util.inherits( Profile, EventEmitter );

module.exports = Profile;

And that's the code in the profile.js file. Did you start this course a while ago and come back to it?

Yes! In fact I did all Node.JS course and thought about refreshing some concepts so I tackled the course again

That explains it! Yeah, when you fork a workspace you copy the code at that point in time. All new students will get the updated code.

Andrew Chalkley THANKS! Yeah im checking the profile JS again to understand a little bit more the code, thanks Andrew.

So the way to fix this is by updating the profile.js file to this: (I imported https, updated the urls AND modified the profileEmitter when it catches and error take a look at the response.statusCode)

var EventEmitter = require("events").EventEmitter;
var http = require("https");
var util = require("util");

/**
 * An EventEmitter to get a Treehouse students profile.
 * @param username
 * @constructor
 */
function Profile(username) {

    EventEmitter.call(this);

    profileEmitter = this;

    // Connect to the API URL (http://teamtreehouse.com/username.json)
    var request = http.get("https://teamtreehouse.com/" + username + ".json", function(response) {
        var body = "";

        if (response.statusCode !== 200) {
            request.abort();
            //Status Code Error
            profileEmitter.emit("error", new Error("There was an error getting the profile for " + username + ". (" + response.statusCode + ")"));
        }

        // Read the data
        response.on('data', function (chunk) {
            body += chunk;
            profileEmitter.emit("data", chunk);
        });

        response.on('end', function () {
            if(response.statusCode === 200) {
                try {
                    // Parse the data
                    var profile = JSON.parse(body);
                    profileEmitter.emit("end", profile);
                } catch (error) {
                    profileEmitter.emit("error", error);
                }
            }
        }).on("error", function(error){
            profileEmitter.emit("error", error);
        });
    });
}

util.inherits( Profile, EventEmitter );

module.exports = Profile;
