7,708 PointsAny username I type in after my localhost:(port) is not being displayed on the page
Hello I'm about 6 minutes into the video when we're testing if everything is working with a simple response where you type in localhost:(port)/chalkers
to display the response.write(values.username + "has "+ values.badges + "badges\n");
.
However nothing is being written to the page for me.
A few things before I post my code: I am running my own node.js environment on my local computer and not using the treehouse option and my port is: 1337. I'm pretty sure that something has been overlooked in my code because when I start the server without any searching of usernames it all shows up fine with Header, Search, Footer, but a /chalkers
for example just gives me Header, Footer.
router.js:
var Profile = require("./profile.js")
// Handle the HTTP route GET / and POST / i.e. Home
function home(request, response) {
//if url = "/" && GET
//url is a property of the incoming message
if (request.url === "/") {
//show search field
response.writeHead(200, { 'Content-Type': 'text/plain' });
response.write("Header\n");
response.write("Search\n");
response.end("Footer\n")
}
//if url = "/" && POST
//redirect to /:username
}
// Handle the HTTP route GET / :username i.e. /mauricetafollacunningham
function user(request, response) {
//if url = "/....."
var username = request.url.replace("/", "");
if (username.length > 0) {
response.writeHead(200, { 'Content-Type': 'text/plain' });
response.write("Header\n");
//get json from Treehouse
var studentProfile = new Profile(username);
//on "end"
studentProfile.on("end", function(profileJSON){
//show profile
//Store the values which we need
var values = {
avatarUrl: profileJSON.gravatar_url,
username: profileJSON.profile_name,
badges: profileJSON.badges.length,
javascriptPoints: profileJSON.points.JavaScript
}
//Simple Response
response.write(values.username + "has "+ values.badges + "badges\n");
response.end("Footer\n");
});
//on "error"
studentProfile.on("error", function(error){
// show error
response.end("Footer\n")
});
}
}
module.exports.home = home;
module.exports.user = user;
app.js
//Problem: We need a simple way to look at a user's badge count and JavaScript points from a web browser
//Solution: Use node.js to perform the profile lookups and serve our template via HTTP
var router = require("./router.js");
//Create a web server
const http = require('http');
const hostname = '127.0.0.1';
const port = 1337;
http.createServer((request, response) => {
router.home(request, response);
router.user(request, response)
//response.end('Hello World\n');
}).listen(port, hostname, () => {
console.log("Server running at http://${hostname}:${port}/");
});
//4. Function that handles the reading of files and merge in value
// read from file and get a string
//merge values in to a string

7,708 PointsOkay so I figured out that I needed to require both http and https in profile.js and change the references on a few lines cool, but now after I enter in usernames my server eventually dies. I'm given Error: write after end
in the console.
This one has me really stuck.

948 PointsAre you getting any output at all? I am getting something similar.
I put a console.log in studentProfile.on("error", function(error){ // show error response.end("Footer\n") }); It looks like I am getting an error there [Error: There was an error getting the profile for favicon.ico. (Not Found)]
It looks like profile is not emitting the correct data.
