DESCRIPTION ^

REST::Google::Feeds provides OO interface to Google REST (aka AJAX) API for feeds.

METHODS ^

__PACKAGE__->http_referer()

Get/set HTTP Referer header.

Note: Google says that you should supply a valid HTTP referer header each time you perform a request to their AJAX API, so new() raises warning unless referer is specified.

__PACKAGE__->new()

q argument should contain URL to a valid RSS or Atom feed. Please refer to 'Google Feeds AJAX API' documentation for complete list of arguments for Google Feeds service. E.g.:

        my $res = REST::Google::Feeds->new(
                q => 'http://digg.com/rss/index.xml',
        );

The code above will perform a following HTTP GET request:

        http://ajax.googleapis.com/ajax/services/feed/load?q=http%3A%2F%2Fdigg.com%2Frss%2Findex.xml&v=1.0

Note: You can left protocol version number unspecified while making your searches since v=1.0 is passed by default.

See REST::Google new method.

responseData

Method returns REST::Google::Feeds::Data object, which has a single method feed.

        my $res = REST::Google::Feeds->new(
                q => 'http://digg.com/rss/index.xml',
        );

        my $feed = $res->responseData->feed;
feed

Method returns REST::Google::Feeds::Feed object, which has accessors for all incapsulated data.

        my $feed = $res->responseData->feed;
        print $feed->title;
        print $feed->link;

Attributes of $feed are:

        title
        link
        author
        description
        type
        entries

Obtaining feed entries:

        foreach my $entry ($feed->entries) {
                print $entry->title;
        }

Attributes of $entry are:

        title
        link
        author
        publishedDate
