=head1 NAME
CGI::Application::Plugin::Authorization::Driver - Base module for building driver classes
for CGI::Application::Plugin::Authorization
=head1 SYNOPSIS
package CGI::Application::Plugin::Authorization::Driver::MyDriver;
use base qw(CGI::Application::Plugin::Authorization::Driver);
sub authorize_user {
my $self = shift;
my @params = @_;
if ( >>> Valid Access Permissions <<< ) {
return 1;
}
return;
}
=head1 DESCRIPTION
This module is a base class for all driver classes for the L<CGI::Application::Plugin::Authorization>
plugin. Each driver class is required to provide only one method to authorize the given parameters.
Often this will be a list of groups that the user needs to be a part of, although it could be anything.
=head1 METHODS
=head2 new
This is a constructor that can create a new Driver object. It requires an Authorization object as its
first parameter, and any number of other parameters that will be used as options depending on which
Driver object is being created. You shouldn't need to call this as the Authorization plugin takes care
of creating Driver objects.
=cut
sub new {
my $class = shift;
my $self = {};
my $authz = shift;
my @options = @_;
bless $self, $class;
$self->{authz} = $authz;
Scalar::Util::weaken($self->{authz}); # weaken circular reference
$self->{options} = \@options;
$self->initialize;
return $self;
}
=head2 initialize
This method will be called right after a new Driver object is created. So any startup customizations
can be dealt with here.
=cut
sub initialize {
my $self = shift;
# override this in the subclass if you need it
return;
}
=head2 options
This will return a list of options that were provided when this driver was configured by the user.
=cut
sub options { return (@{$_[0]->{options}}) }
=head2 find_option
This method will search the Driver options for a specific key and return
the value it finds. This method assumes that the Driver configuration contains
a hash of information. If it does not, then you will have to parse the option
manually in the subclass.
=cut
sub find_option {
my $self = shift;
my $key = shift;
my @options = $self->options;
my $marker = 0;
foreach my $option (@options) {
if ($marker) {
return $option;
} elsif ($option eq $key) {
# We need the next element
$marker = 1;
}
}
return;
}
=head2 authz
This will return the underlying L<CGI::Application::Plugin::Authorization> object. In most cases it will
not be necessary to access this.
=cut
sub authz { return $_[0]->{authz} }
=head2 username
This will return the name of the current logged in user by calling the
C<username> method documented in L<CGI::Application::Plugin::Authorization>.
=cut
sub username {
my $self = shift;
return $self->authz->username;
}
=head2 authorize
# User must be in the admin group to have access to this runmode
return $self->authz->forbidden unless $self->authz->authorize('admin');
This method will verify that the currently logged in user (as found through L<username>)
passes the authorization checks based on the given parameters, usually a list of groups.
=cut
sub authorize {
my $self = shift;
my @groups = @_;
return $self->authorize_user($self->username, @groups);
}
=head2 authorize_user
This method needs to be provided by the driver class. It needs to be an object method
that accepts a username, followed by a list of parameters, and will verify that the
user passes the authorization checks based on the given parameters. It should return
a true value if the checks succeed.
=cut
sub authorize_user {
die "authorize_user must be implemented in the subclass";
}
