So I'm not certain what trouble you're having, but in my example, the handleError function is not attached to the scope (and certainly not $rootScope). The reason it works is because the second argument to a promise's .then function is a function that is called on an error. Good luck!

Hi Small detail. With the illustrated code, I had a node error in the server console: Error: Can't set headers after they are sent.

This happened when you deal with a usern/pwd error case, you trigger a res.end but at the end of the function res.send is anyway executed.

To solve that I've just added 'else if' and 'else' in the code of the 'authenticate' function: ''' if (!body.username || !body.password) { res.status(400).end('Must provide username and password!'); } else if (body.username !== user.username || body.password !== user.password) { res.status(401).end('Username or password is incorrect.'); } else { next(); } '''

Dear Kent Thank you for your course. You are very good developer and your content is very good but I am very frustrated that I cannot type fast like you and please review Lukas Ruebbelke course format. I was able to finish his 2 courses very fast. Please change something because for this reason I am avoiding Joe Eames classes on pluralsite. You really good in what you do but please change something. I really want to learn from you and there is no speed control. Also at the begging of each lesson explain what are you trying to do.

Which would be a better practice to send username and password? I'm sending it via headers in this way: authorizationHeader = "Basic " + btoa(email + ":" + passphrase); JWT could serve for this purpose ? how?

That's not how I do it in this series. And I wouldn't recommend doing it that way. You don't want your JWT to contain sensitive information because it can be decoded without the private key.

function authenticate(req, res, next) { var body = req.body;

console.log(body.username);

not getting the value says "undefined."

In server.js, if the authentication "UTIL function" responds to the request by sending a 400 or 401 it continues to next() and tries to set the response header again at line 23 res.send(user) and results in an error in the console stating that you "Can't set headers after they are sent." How can this be avoided. I could conditionally call next() only if there were no error headers sent but I get the feeling I'm doing more than I should need to and I'm missing something.
