NAME

Search::Elasticsearch::Role::Client::Direct - Request parsing for Direct clients

VERSION

version 2.02

DESCRIPTION

This role provides the single parse_request() method for classes which need to parse an API definition from Search::Elasticsearch::Role::API and convert it into a request which can be passed to "perform_request()" in Search::Elasticsearch::Transport.

METHODS

perform_request()

            

              
              
$request = $client->parse_request(\%defn,\%params);
            
          

The %defn is a definition returned by "api()" in Search::Elasticsearch::Role::API with an extra key name which should be the name of the method that was called on the client. For instance if the user calls $client->search, then the name should be "search".

parse_request() will turn the parameters that have been passed in into a path (via "path_init()" in Search::Elasticsearch::Util::API::Path), a query-string hash (via "qs_init" in Search::Elasticsearch::Util::API::QS) and will through a body value directly.

NOTE: If a path key is specified in the %params then it will be used directly, instead of trying to build path from the path template. Similarly, if a params key is specified in the %params, then it will be used as a basis for the query string hash. For instance:

            

              
              
$client->perform_request(
    {
        method => 'GET',
        name   => 'new_method'
    },
    {
        path   => '/new/method',
        params => { foo => 'bar' },
        body   => \%body
    }
);
            
          

This makes it easy to add support for custom plugins or new functionality not yet supported by the released client.
