ip_address() removed from Drupal, incorrect client ip set for fraud handling when using a front end proxy

[adixon]

When using this extension with Drupal 8 and a front-end proxy (e.g. varnish), it sends incorrect information to the iats server about the originating request (client) ip.

This issue does not affect sites that are not using a front end proxy.

Specifically, this code "(function_exists('ip_address') ? ip_address() : $_SERVER['REMOTE_ADDR']" is used in multiple places to identify the client ip.

This worked for D7 and D6, but as per:

https://www.drupal.org/node/1969794

it won't.

Conclusion: for Drupal 8+, we should be defining

function ip_address() {

return Drupal::request()->getClientIp();

}
