TheGameCrafter::Client - A simple client to TGC's web services.

=head1 VERSION

version 0.0103

=head1 SYNOPSIS

 use TheGameCrafter::Client;

 my $game = tgc_get('game/528F18A2-F2C4-11E1-991D-40A48889CD00');

 my $session = tgc_post('session', { username => 'me', password => '123qwe', api_key_id => 'abcdefghijklmnopqrztuz' });

 $game = tgc_put('game/528F18A2-F2C4-11E1-991D-40A48889CD00', { session_id => $session->{id}, name => 'Lacuna Expanse' });

 my $status = tgc_delete('game/528F18A2-F2C4-11E1-991D-40A48889CD00', { session_id => $session->{id} });

=head1 DESCRIPTION

A light-weight wrapper for The Game Crafter's (L) RESTful API (L). This wrapper basically hides the request cycle from you so that you can get down to the business of using the API. It doesn't attempt to manage the data structures or objects the web service interfaces with.

=head1 SUBROUTINES

The following subroutines are exported into your namespace wherever you C.

=head2 tgc_get(path, params)

Performs a C request, which is used for reading data from the service.

=over

=item path

The path to the REST interface you wish to call. You can abbreviate and leave off the C part if you wish.

=item params

A hash reference of parameters you wish to pass to the web service.

    my ($path, $params) = @_;
    my $uri = _create_uri($path);
    $uri->query_form($params);
    return _process_request( GET $uri->as_string );
}

=head2 tgc_delete(path, params)

Performs a C request, deleting data from the service.

=over

=item path

The path to the REST interface you wish to call. You can abbreviate and leave off the C part if you wish.

=item params

}

=head2 tgc_put(path, params)

Performs a C request, which is used for updating data in the service.

Performs a C request, which is used for creating data in the service.
