=head1 NAME
Apache::Session::Browseable::Redis - Add index and search methods to
Apache::Session::Redis
=head1 SYNOPSIS
use Apache::Session::Browseable::Redis;
my $args = {
server => '127.0.0.1:6379',
# Choose your browseable fileds
Index => 'uid mail',
};
# Use it like Apache::Session
my %session;
tie %session, 'Apache::Session::Browseable::Redis', $id, $args;
$session{uid} = 'me';
$session{mail} = 'me@me.com';
$session{unindexedField} = 'zz';
untie %session;
# Apache::Session::Browseable add some global class methods
#
# 1) search on a field (indexed or not)
my $hash = Apache::Session::Browseable::Redis->searchOn( $args, 'uid', 'me' );
foreach my $id (keys %$hash) {
print $id . ":" . $hash->{$id}->{mail} . "\n";
}
# 2) Parse all sessions
# a. get all sessions
my $hash = Apache::Session::Browseable::Redis->get_key_from_all_sessions();
# b. get some fields from all sessions
my $hash = Apache::Session::Browseable::Redis->get_key_from_all_sessions('uid', 'mail')
# c. execute something with datas from each session :
# Example : get uid and mail if mail domain is
my $hash = Apache::Session::Browseable::Redis->get_key_from_all_sessions(
sub {
my ( $session, $id ) = @_;
if ( $session->{mail} =~ /mydomain.com$/ ) {
return { $session->{uid}, $session->{mail} };
}
}
);
foreach my $id (keys %$hash) {
print $id . ":" . $hash->{$id}->{uid} . "=>" . $hash->{$id}->{mail} . "\n";
}
=head1 DESCRIPTION
Apache::Session::browseable provides some class methods to manipulate all
sessions and add the capability to index some fields to make research faster.
