NAME¶
Plack::Session::Store::DBI - DBI-based session store
SYNOPSIS¶
use Plack::Builder;
use Plack::Middleware::Session;
use Plack::Session::Store::DBI;
my $app = sub {
return [ 200, [ 'Content-Type' => 'text/plain' ], [ 'Hello Foo' ] ];
};
builder {
enable 'Session',
store => Plack::Session::Store::DBI->new(
dbh => DBI->connect( @connect_args )
);
$app;
};
# set get_dbh callback for ondemand
builder {
enable 'Session',
store => Plack::Session::Store::DBI->new(
get_dbh => sub { DBI->connect( @connect_args ) }
);
$app;
};
# with custom serializer/deserializer
builder {
enable 'Session',
store => Plack::Session::Store::DBI->new(
dbh => DBI->connect( @connect_args )
# YAML takes it's args the opposite order
serializer => sub { YAML::DumpFile( reverse @_ ) },
deserializer => sub { YAML::LoadFile( @_ ) },
);
$app;
};
DESCRIPTION¶
This implements a DBI based storage for session data. By default it will use
Storable and MIME::Base64 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.
SESSION TABLE SCHEMA¶
Your session table must have at least the following schema structure:
CREATE TABLE sessions (
id CHAR(72) PRIMARY KEY,
session_data TEXT
);
Note that MySQL TEXT fields only store 64KB, so if your session data will exceed
that size you'll want to move to MEDIUMTEXT, MEDIUMBLOB, or larger.
