NAME

WWW::IRail::API::Liveboard - HTTP::Request builder and HTTP::Response parser for the IRail API Liveboard data

SYNOPSIS

make_request ( station => 'oostende' );     # departures by default

make_request ( to => 'oostende' );          # arrivals coming into oostende

DESCRIPTION

This module builds a HTTP::Request and has a parser for the HTTP::Response. It's up to you to transmit it over the wire. If don't want to do that yourself, don't use this module directly and use WWW::IRail::API instead.

METHODS

make_request( key = 'val'> | { key = 'val' }> )

Only the station argument is required, but if you either use to or from it will be seen as the station name with the direction set accordingly. Memento: trains leaving from => 'oostende' and trains arriving into => 'oostende'. If the direction could not be deduced it defaults to 'departures'

make_request ( from => 'oostende' );

make_request ( station => 'oostende', direction => 'departures' );

make_request ( { station => 'oostende', dir => 'arr' } );

the API direction parameter is extracted from your input using m/(arr|dep)/i so you can choose between less typing or better readability.

parse_response( $http_response, dataType )

rses the HTTP::Response you got back from the server, which if all went well contains XML. That XML is then transformed into other data formats

  • xml

  • XML

  • YAML

  • JSON

  • perl (default)
