NAME

Plack::Session::Store::File - Basic file-based session store

CONTENTS

SYNOPSIS



  use Plack::Builder;
  use Plack::Middleware::Session;
  use Plack::Session::Store::File;

  my $app = sub {
      return [ 200, [ Content-Type => text/plain ], [ Hello Foo ] ];
  };

  builder {
      enable Session,
          store => Plack::Session::Store::File->new(
              dir => /path/to/sessions
          );
      $app;
  };

  # with custom serializer/deserializer

  builder {
      enable Session,
          store => Plack::Session::Store::File->new(
              dir          => /path/to/sessions,
              # YAML takes its args the opposite order
              serializer   => sub { YAML::DumpFile( reverse @_ ) },
              deserializer => sub { YAML::LoadFile( @_ ) },
          );
      $app;
  };



DESCRIPTION

This implements a basic file based storage for session data. By default it will use Storable to serialize and deserialize the data, but this can be configured easily.

This is a subclass of Plack::Session::Store and implements its full interface.

METHODS

<B>new ( B>%params<B> )B> The %params can include dir, serializer and deserializer options. It will check to be sure that the dir is writeable for you.
<B>dirB> This is the directory to store the session data files in, if nothing is provided then /tmp is used.
<B>serializerB> This is a CODE reference that implements the serialization logic. The CODE ref gets two arguments, the $value, which is a HASH reference to be serialized, and the $file_path to save it to. It is not expected to return anything.
<B>deserializerB> This is a CODE reference that implements the deserialization logic. The CODE ref gets one argument, the $file_path to load the data from. It is expected to return a HASH reference.

BUGS

All complex software has bugs lurking in it, and this module is no exception. If you find a bug please either email me, or add the bug to cpan-RT.
