router.get没有参数但要求参数

Question

I am trying to use express nodejs and JWT. Here is the source code of what I've been through: link .

I protect all routes, except routes that I declare inside the jwt.js file.

1. the '/trial' url, is not protected. The controller is inside the trial.controller.js file. When I hit the url in postman, both with the get and the post method and without any auth ( No Auth ), I get what I expect.
2. But, the same things do not happen when I hit '/users/testdata' . It's not protected, but if I hit it with the get method and without any auth, it returns error 500 with the message "Cannot read property 'sub' of undefined" in postman. But, when I hit it with the post method, I get what I expect.

So, what's wrong with the get method?

Please see the above link for complete code. Any help will mean a lot to me. Thank you!

Answer 1

The problem occurs because the route router.get('/:id', getById); is defined before the route router.get('/testdata', getTest); . So when you perform a request to the /testdata route, it is handled by the /:id route, that requires authentication to work, and uses the currentUser.sub attribute, although the currentUser variable is currently undefined.

Just change the order from

router.get('/:id', getById);
router.get('/testdata', getTest);

to

router.get('/testdata', getTest);
router.get('/:id', getById);
