[SOLVED] Optional POST Parameters in Mojolicious Lite with Perl

Optional POST Parameters in Mojolicious Lite with Perl

Is there a way to denote a POST parameter as optional in Perl using Mojolicious Lite? For instance, is there a way to make the server not return 404 if param2 is not defined in the request body?

post "/my_post" => \&render(post_callback);

sub post_callback {
    my ($mojo) = @_;
    my $param1 = $mojo->param("param1");
    my $param2 = $mojo->param("param2");
}

Solution

My problem was that I misunderstood how mojolicious was routing to the callback. The following code works with both parameters being optional:

#!/usr/bin/env perl
use strict;
use warnings;
use Mojolicious::Lite;

post '/' => sub {
    my ($mojo) = @_;
    my $param1 = $mojo->param("param1");
    my $param2 = $mojo->param("param2");
    $mojo->render(text => "param1: $param1, param2: $param2");
};

app->start;

If you run this using: ./my_server.pl daemon you will be able to send POST requests with any combination of parameters.
