PREREQUISITES

This package is part of a larger distribution and was NOT intended to be used directly. In order for this plugin to work properly, the following packages must be installed:

  Apache2::WebApp
  Apache2::WebApp::Plugin::Cookie
  Apache::Session
  Params::Validate
  Switch

INSTALLATION

From source:

  $ tar xfz Apache2-WebApp-Plugin-Session-0.X.X.tar.gz
  $ perl MakeFile.PL PREFIX=~/path/to/custom/dir LIB=~/path/to/custom/lib
  $ make
  $ make test     <--- Make sure you do this before contacting me
  $ make install

Perl one liner using CPAN.pm:

  perl -MCPAN -e 'install Apache2::WebApp::Plugin::Session'

Use of CPAN.pm in interactive mode:

  $> perl -MCPAN -e shell
  cpan> install Apache2::WebApp::Plugin::Session
  cpan> quit

Just like the manual installation of Perl modules, the user may need root access during this process to insure write permission is allowed within the installation directory.

CONFIGURATION

Unless it already exists, add the following to your projects webapp.conf

  [session]
  storage_type = file     # options - file | mysql | memcached
  expires = 1h            # default 24h

OBJECT METHODS

create

Create a new session.

By default, when a new session is created, a browser cookie is set that contains a session_id. Upon success, this session identifier is returned, which can to be used to set a customized session cookie.

  my $session_id = $c->plugin('Session')->create( $c, 'login',
      {
          username => 'foo',
          password => 'bar',
      }
    );

get

Return session data as a hash reference.

  my $data_ref = $c->plugin('Session')->get( $c, 'login' );

  print $data_ref->{username};     # foo is the value

update

Update existing session data.

  $c->plugin('Session')->update( $c, 'login',
      {
          last_login => localtime(time),
          remember   => 1,
      }
    );

delete

Delete an existing session.

  $c->plugin('Session')->delete( $c, 'login' );

EXAMPLE

  package Example;

  sub _default {
      my ( $self, $c ) = @_;

      $c->plugin('Session')->create( $c, 'login',
          {
              username => 'foo',
              password => 'bar',
          }
        );

      $c->plugin('CGI')->redirect( $c, "/app/example/verify" );
  }

  sub verify {
      my ( $self, $c ) = @_;

      my %session = $c->plugin('Session')->get( $c, 'login' );

      $c->request->content_type('text/html');

      print $session{username} . ' - ' . $session{password};
  }

  1;
