Back End Development and APIs Projects - URL Shortener Microservice

My URL Shortener seems to work for me but doesn’t pass the tests.

Do you have any idea what could be the issue? Perhaps I’m not treating queries the right way?

Your urlValidator class does not work properly.

Thanks a lot! That fixed the issue and I was able to pass the tests!


Hi Randell.

I think it was fine. Keep in mind I do url validation and after dns lookup. I believe that is the reason those URL fail.

Thanks again!!

Yes, I modified the regex. You can find the validator here:

It seems to work properly to me (see quick test below):

Hi Randell.

Sorry, I don’t understand what your point is.

The provided urls fail the dns.lookup test, that’s why my app returns {“error”:“invalid url (dns lookup)”}.

Isn’t that the expected behavior?
