Cannot find server or Server didnt respond error.

Hey gang,

So I followed all the directions on the course but in the end I got Data not received or server not found error. And I even changed the server to be a https server.

This is the app.js:

    var https = require('https');
    var router = require('./router.js');

    var server = https.createServer({},function(req,res) {
        router.homeRoute(req, res);
        router.userRoute(req, res);
    });

    server.listen(3000);
    console.log('Listening on port 3000');

This is the router.js;

    var renderer = require('./renderer.js');
    var Profile = require('./profile.js');

    function homeRoute(req, res) {
        if(req.url === '/') {
            if(req.method.toLowerCase() === 'get') {
                res.writeHead(200, {'Content':'text/html'});
                renderer.view('header', {}, res);
                renderer.view('search', {}, res);
                renderer.view('footer', {}, res);
                res.end();
            } else {
            }
        }
    }

    function userRoute(req, res) {
        var username = req.url.replace('/','');
        if(username.length > 0){
            var userProfile = new Profile(username);
            res.writeHead(200, {'Content':'text/html'});
            console.log('The data I got from the request is ',jsonData);
            renderer.view('header', {}, res);
            userProfile.on('end', function(jsonData) {
                var values = {
                    avatarUrl: jsonData.gravatar_url,
                    username: jsonData.profile_name,
                    badges: jsonData.badges.length,
                    javascriptPoints: jsonData.points.JavaScript
                };
                renderer.view('profile', values, res);
                renderer.view('search', {}, res);
                renderer.view('footer', {}, res);
                res.end();
            });

            userProfile.on('error', function(error) {
                res.writeHead(200, {'Content':'text/html'});
                console.log('The data I got from the request is ',{errorMessage: error.message});
                renderer.view('header', {}, res);
                renderer.view('error', {errorMessage: error.message}, res);
                renderer.view('search', {}, res);
                renderer.view('footer', {}, res);
                res.end();
            });
        }
    }

    module.exports.homeRoute = homeRoute;
    module.exports.userRoute = userRoute;

I didn't update it to redirect the post request to a get request but even when I make a GET request to '/' route, I still get an error.

Help?

Since Treehouse updated to using https, the code gets a bit wonky to fix. You actually don't need to include https in your app.js file. Instead, I believe you need both http and https in your profile.js file.

app.js

// This is my app.js file. You shouldn't need https here.
var http = require('http');
var router = require('./router.js');

http.createServer(function (request, response) {
  router.home(request, response);
  router.user(request, response);
}).listen(1337, '127.0.0.1');

console.log('Server running at http://127.0.0.1:1337/');

profile.js

// This is not a complete file. I've only included the relevant portions.
var https = require("https");
var http = require("http");

function Profile(username) {
  // . . .
  // You'll need to use https here to get the Treehouse information.
  var request = https.get("https://teamtreehouse.com/" + username + ".json", function(response) {
    // . . .
    if (response.statusCode !== 200) {
      request.abort();
      // You'll need to use http here to get the status code.
      profileEmitter.emit("error", new Error("There was an error getting the profile for " + username + ". (" + http.STATUS_CODES[response.statusCode] + ")"));
    };
    // . . .
  });
};
// . . .

Hopefully that makes sense, but please let me know if you have any questions. It can be a bit tricky following along, now that the videos don't necessarily match the current protocol. Happy coding! :)
