10         package Lemonldap::NG::Portal::Captcha::My;
11
12         use strict;
13         use Mouse;
14         # Add constants used by this module
15
16         our $VERSION = '0.1';
17
18         extends 'Lemonldap::NG::Portal::Main::Plugin';
19
20         sub init {
21             my $self = shift;
22             return 1;
23         }

27
28           # Read option from the manager configuration
29           my $option = $self->conf->{captchaOptions}->{option1};
30
31           # This can be used to inject custom JS code at the beginning
32           # of the page
33           my $script = <your html code>;
34           $req->data->{customScript} .= $script;
35
36           # This will add your custom HTML code to the protected form
37           my $html = <your html code>;
38           $req->captchaHtml($html);
39         }
40
41         sub check_captcha {
42           my ( $self, $req ) = @_;
43
44           my $captcha_input = $req->param('some_post_param');
45           my $is_captcha_valid = <your code here>;
46
47           if($is_captcha_valid) {
48               return 1;
49           } else {
50               return 0;

DESCRIPTION

57       Captcha modules only need to implement two methods: one for
58       initializing the challenge, before the form is displayed, and the other
59       to verify that the submitted response is correct.
60

METHODS

62   Accessors and methods provided by Lemonldap::NG::Portal::Main::Plugin
63       p: portal object
64       conf: configuration hash (as reference)
65       logger alias for p->logger accessor
66       userLogger alias for p->userLogger accessor
67       error: alias for p->error method
68
69   "Routes" management
70       Like each module that inherits from Lemonldap::NG::Portal::Plugin, you
71       can define dedicated routes in a Captcha plugin.
72
73       addAuthRoute: wrapper to Lemonldap::NG::Handler::PSGI::Try
74       addAuthRoute() method
75       addUnauthRoute: wrapper to Lemonldap::NG::Handler::PSGI::Try
76       addUnauthRoute() method
77
78   Methods that must be provided by a Captcha module
79       init_captcha($req)
80
81       This method is called when the protected form is built by
82       LemonLDAP::NG.  Your responsibility is to do any preparatory step, and
83       provide LemonLDAP::NG with the HTML code that it has to display in the
84       form to enable the Captcha.
85
86       This is done by setting "$req->captchaHtml"
87
88       check_captcha($req)
89
90       This method is called after the user submitted the protected form. Your
91       responibility is to check the user's response (usually provided as a
92       POST field), and return 0 if the response is incorrect, 1 if the
93       response is correct.
94

LOGGING

96       Logging is provided by "$self->logger" and "$self->userLogger". See
97       Lemonldap::NG::Portal::Main::Plugin for a detailed description of
98       logging levels.
