Get null for ip address about java

[LiMengyang990726]

Thank you so much for help me protect my token. And I have kinda solved the question.

1. request.getRemoteAddr() return the right format of ip address. E.g. 8.8.8.8
2. I have changed the UserLocation userLocation = new UserLocation(user, ipResponse.getCountryName()); to UserLocation userLocation = new UserLocation(user, ipResponse.getCountryCode());. And it works perfectly.
3. If still want getCountryName(), add an additional country-code-to-name json file will do.

This service is great! A gentle reminder is that you are not able to test this in your development environment (meaning localhost, as it always return 127.0.0.1), you can only test it after you deployed it.

@LiMengyang990726 Probably need a bit more info. What does request.getRemoteAddr() return for the particular time you get null?
