NAME

WWW::GoKGS::Scraper - Abstract base class for KGS scrapers

SYNOPSIS

use parent 'WWW::GoKGS::Scraper';
use URI;
use Web::Scraper;

sub _build_base_uri {
    URI->new('http://www.gokgs.com/...');
}

sub _build_scraper {
    my $self = shift;

    scraper {
        ...
    };
}

DESCRIPTION

This module is an abstract base class for KGS scrapers. KGS scrapers must inherit from this class, and also implement two methods; _build_base_uri and _build_scraper. _build_base_uri must return a URI object which represents a resource on KGS. _build_scraper must return an Web::Scraper object which can scrape the resource. Both of them are called as a method on the object with no parameters.

ATTRIBUTES

$URI = $scraper->base_uri

Returns a URI object which represents a resource on KGS. This attribute is read-only.

$UserAgent = $scraper->user_agent

$scraper->user_agent( LWP::UserAgent->new(...) )

Can be used to get or set an LWP::UserAgent object which is used to GET the requested resource. Defaults to the LWP::UserAgent object shared by Web::Scraper users ($Web::Scraper::UserAgent).

METHODS

$scraper->scrape( URI->new(...) )

$scraper->scrape( HTTP::Response->new(...) )

$scraper->scrape( $html[, $base_uri] )

$scraper->scrape( \$html[, $base_uri] )

Given arguments are passed to the scrape method of an Web::Scraper object built by the _build_scraper method.

$scraper->query( $k1 => $v1, $k2 => $v2, ... )

Given key-value pairs of query parameters, constructs a URI object which consists of base_uri and the query parameters, then pass the URI to the scrape method.
