This class contains a definition of each query string parameter that can be accepeted by actions in the API.
qs_init()
use Elasticsearch::Util::API::QS qw(qs_init); $handler = qs_init( @qs_params ); $qs_hash = $handler->($params);
The qs_init()
sub accepts a list of query string parameter names, and returns a handler which can extract those parameters from \%params
and return a hash of values to be passed as a query string.
For instance:
$handler = qs_init(qw(fields size from)); $params = { fields =>['foo','bar'], size => 10, query=>\%query }; $qs_hash = $handler->($params);
Would result in:
$qs_hash: { fields => 'foo,bar', size => 10}; $params: { query => \%query }
