Tell us what’s happening:
I got 2 issues here:
- Issue1: I don’t know how I can display the IPv6 instead of IPv4 in this exercice. The example given at https://request-header-parser-microservice.freecodecamp.rocks/api/whoami succeeds in doing so, but I can’t get the same and the only ipaddress I get is the IPv4
- Issue 2: I had to “Google” my way through this, especially for the ip part. I was (and still am) super confused with all the options for getting the ip:
- req.ip
- req.ips (supposedly an array
-req.header[‘x-forwarded-for’] (which actually doesn’t work) or req.headers[‘x-forwarded-for’] (which work)
Overall I passed the challenge, but I don’t fully understand why and it’s very frustrating. Any comprehensive literature on the topic would help a ton
