readClient static method

({String? ip, String scheme}) readClient(HttpRequest req, List<String> trusted)

The client ip and scheme of req. trusted is the trustedProxies setting. It is parsed once per isolate.

Implementation

static ({String? ip, String scheme}) readClient(
  HttpRequest req,
  List<String> trusted,
) {
  if (!identical(trusted, _cachedList)) {
    _cached = TrustedProxy(trusted);
    _cachedList = trusted;
  }
  String? address = req.connectionInfo?.remoteAddress.address;
  String? remote = address == null ? null : normalize(address);
  if (remote == null || !_cached.enabled) return (ip: remote, scheme: 'http');
  return (
    ip: _cached.clientIp(remote, req.headers.value('x-forwarded-for')),
    scheme: _cached.scheme(remote, req.headers.value('x-forwarded-proto')),
  );
}
