【问题描述】：

我一直在 Perl 中使用 TMDB 来获取很多关于电影的信息，例如：

my @results = $tmdb->search->movie("Back To The Future");

我得到了很多信息，很多哈希和数组，我得到了我正在寻找的所有信息。但无论我挖多深，我似乎都找不到找到 MPAA 对电影分级的路径。

有人有这方面的经验吗？我觉得我陷入了一个永恒的循环。

最好打印一个Dumper 值并查看。

您可以获得这样的认证：

use feature qw(say);
use strict;
use warnings;

use TMDB;

my $tmdb = TMDB->new(
   apikey => '?????????',  # API Key
   lang   => 'en',             # A valid ISO 639-1 (Aplha-2) language code
);

my @results = $tmdb->search->movie("Back To The Future");

for my $result (@results) {
    my $id = $result->{id};
    my $movie = $tmdb->movie( id => $id );
    my $releases = $movie->releases;
    my @cert = map { $_->{certification} } @$releases;
    say $result->{title}, " : ", join ",", @cert;
}

输出：
