What's the proper way to retrieve the client's IP address?

[Alexander Karelas]

I know there's $self->tx->remote_address, but that retrieves the address
of the reverse proxy (127.0.0.1).

Because even though I have set up a X-Real-IP header and a
X-Forwarded-For header, neither of these headers get used by
$self->tx->remote_address.

What's the right way to retrieve the client's IP address?

In your case, that's $c->req->headers->header('X-Forwarded-For');

I think that contains a comma-separated list of IP addresses, whereas
the X-Real-IP header always contains just one address.

Try setting { hypntoad => { proxy => 1, listen => [...] } in the config file, if you are using hypnotoad, or set the MOJO_REVERSE_PROXY=1 environment variable in other cases. Support for the environment variable was added in Mojolicious 5.11.

This will allow retrieving the IP address using $self->tx->remote_address

Create helper:

    $self->renderer->add_helper(ip => sub {

      my $self = shift;

      my $for  = $self->req->headers->header('X-Forwarded-For');

      return $for && $for !~ /unknown/i ? $for : undef || $self->req->headers->header('X-Real-IP') || $self->tx->{remote_address};

    });

If you have set up the reverse proxy correct, you can just do $c->remote_address;

No idea why you want to look into the tx hash. You should always use the methods.

Look here: (there's also cookbooks for other servers on that page)

Also remember to set the MOJO_REVERSE_PROXY=1 environmnt variable as I said earlier in this thread.

That worked. Thank you.
