从认识MusicBrainz的CPAN模块推出的类型？ [英] Understanding the type of out put from Musicbrainz cpan module?

问题描述

即时通讯使用的MusicBrainz CPAN模块查找一张专辑，但有试图破译我收到输出的几个问题进出口。我使用的数据::自卸车看看它，它似乎是一个哈希或某种阵列，但是当我尝试检查我遇到的问题类型。

Im using the Musicbrainz cpan module to look up an album but Im having a few issues trying to decipher the output I recieve. I used data::Dumper to have a look at it, and it appears to be a hash or array of some sort but when I try to check the type I run into problems.

my $ws = WebService::MusicBrainz::Release->new();

my $response = $ws->search({ TITLE => 'ok computer' });


if (ref($response) eq "REF" || ref($response) eq "SCALAR" || ref($response) eq "ARRAY" || ref($response) eq "HASH" || ref($response) eq "CODE" || ref($response) eq "GLOBE")

 {
 print "\n What sort of thing is it? \n";
 }
