NAME Plack::Session::Store::MongoDB - MongoDB based session store for Plack apps. VERSION version 0.4 SYNOPSIS use Plack::Builder; use Plack::Middleware::Session; use Plack::Session::Store::MongoDB; my $app = sub { return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ]; }; builder { enable 'Session', store => Plack::Session::Store::MongoDB->new( session_db_name => 'myapp', coll_name => 'myapp_sessions', # defaults to 'session' host => 'mongodb.myhost.com', # defaults to 'localhost' port => 27017 # this is the default ); $app; }; # alternatively, you can just pass a MongoDB::Connection object: builder { enable 'Session', store => Plack::Session::Store::MongoDB->new( session_db_name => 'myapp', conn => MongoDB::Connection->new ); $app; }; DESCRIPTION This module implements a MongoDB storage for session data. This has the advantage of being a simple (no need to generate a database scheme or even create the necessary database/collections), yet powerful backend. It requires, of course, a running MongoDB daemon to work with. METHODS new( %params ) Creates a new instance of this module. Requires a hash of parameters containing 'session_db_name' with the name of the MongoDB database to use and any options available by MongoDB::Connection, most probably 'host' (the hostname of the server where the MongoDB daemon is running, defaults to 'localhost') and 'port' (the port where the MongoDB daemon is listening, defaults to 27017, the default MongoDB port). You can also optionally pass the 'coll_name' parameter, denoting the name of the collection in which sessions will be stored (will default to 'sessions'). Alternatively, you can pass a 'conn' parameter and give it an already created MongoDB::Connection object. You will still need to pass 'session_db_name' when doing this. NOTE: in versions before 0.3, the 'session_db_name' option was called 'db_name'. This has been changed since 'db_name' is a MongoDB::Connection option that might differ from you session database, and you should be able to pass both if you need to. fetch( $session_id ) Fetches a session object from the database. store( $session_id, \%session_obj ) Stores a session object in the database. If a database error occurs when attempting to store the session, this method will die. remove( $session_id ) Removes the session object from the database. If a database error occurs when attempting to remove the session, this method will generate a warning.
