Plack::Session::State(3pm) User Contributed Perl Documentation Plack::Session::State(3pm)
NAME
Plack::Session::State - Basic parameter-based session state
SYNOPSIS
use Plack::Builder;
use Plack::Middleware::Session;
use Plack::Session::State;
my $app = sub {
return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
};
builder {
enable 'Session',
state => Plack::Session::State->new;
$app;
};
DESCRIPTION
This will maintain session state by passing the session through the request params. It does not do this automatically though, you are
responsible for passing the session param.
This should be considered the state "base" class (although subclassing is not a requirement) and defines the spec for all
Plack::Session::State::* modules. You will only need to override a couple methods if you do subclass. See Plack::Session::State::Cookie for
an example of this.
WARNING: parameter based session ID management makes session fixation really easy, and that makes your website vulnerable. You should
really avoid using this state in the production environment except when you have to deal with legacy HTTP clients that do not support
cookies.
In the future this parameter based state handling will be removed from this base class and will be moved to its own State class.
METHODS
new ( %params )
The %params can include session_key, sid_generator and sid_checker however in both cases a default will be provided for you.
session_key
This is the name of the session key, it defaults to 'plack_session'.
sid_generator
This is a CODE ref used to generate unique session ids, by default it will generate a SHA1 using fairly sufficient entropy. If you are
concerned or interested, just read the source.
sid_validator
This is a regex used to validate requested session id.
Session ID Managment
get_session_id ( $env )
This is the method used to extract the session id from a $env. Subclasses will often only need to override this method and the
"finalize" method.
validate_session_id ( $session_id )
This will use the "sid_validator" regex and confirm that the $session_id is valid.
extract ( $env )
This will attempt to extract the session from a $env by looking for the "session_key" in the request params. It will then check to see
if the session is valid and that it has not expired. It will return the session id if everything is good or undef otherwise.
generate ( $request )
This will generate a new session id using the "sid_generator" callback. The $request argument is not used by this method but is there
for use by subclasses. The $request is expected to be a Plack::Request instance or an object with an equivalent interface.
finalize ( $session_id, $response )
Given a $session_id and a $response this will perform any finalization necessary to preserve state. This method is called by the
Plack::Session "finalize" method. The $response is expected to be a Plack::Response instance or an object with an equivalent interface.
Session Expiration Handling
expire_session_id ( $id, $response )
This will mark the session for $id as expired. This method is called by the Plack::Session "expire" method.
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
