Dancer2::Plugin::reCAPTCHA - Integrate reCAPTCHA into Dancer2 applications

VERSION

version 0.1

SYNOPSIS

Dancer2::Plugin::reCAPTCHA allows you to easily use reCAPTCHA in Dancer2 applications.

Add the plugin to your application:

use Dancer2::Plugin::reCAPTCHA;

Configure its settings in the YAML configuration file:

plugins:
    reCAPTCHA:
        public_key: "public key"
        private_key: "private key"
        theme: "clean"
        use_ssl: 0

Put reCAPTCHA in a template:

[% recaptcha %]

Display it:

return template 'feedback', { 
    recaptcha => recaptcha_display()
};

Validate user input in a route handler:

my $challenge = param('recaptcha_challenge_field');
my $response  = param('recaptcha_response_field');
my $result    = recaptcha_check($challenge, $response);

if ($result->{is_valid}) {
    # Good
}
else {
    # Bad
}
