Perl 弹性搜索批量需要添加标题

我们是否可以选择在Search:：Elasticsearch模块中添加标题

    use Search::Elasticsearch; 

     my $esloc='abc.com';

     my $es = Search::Elasticsearch->new(nodes => [
            "$esloc"],
            timeout => 60,
            no_refresh   => 0,
            userinfo => 'username:password'
        );

您应该能够这样做：

 my $es = Search::Elasticsearch->new(nodes => [
        "$esloc"],
        timeout => 60,
        no_refresh   => 0,
        userinfo => 'username:password',
        default_headers => { 'Content-Type' => 'application/ndjson' }
    );

谢谢@Val。我已尝试添加自定义标题。它不接受它。我们需要为此添加什么吗？谢谢你的迅速回复
