Search::Elasticsearch::Cxn::HTTPTiny3pm

Version

version 8.12

Overview

Provides the default HTTP Cxn class and is based on HTTP::Tiny. The HTTP::Tiny backend is fast, uses pure Perl, support proxies and https and provides persistent connections.

This class does Search::Elasticsearch::Role::Cxn, whose documentation provides more information, and Search::Elasticsearch::Role::Is_Sync.

Configuration

SSL/TLS

Search::Elasticsearch::Cxn::HTTPTiny uses IO::Socket::SSL to support HTTPS. By default, no validation of the remote host is performed.

This behaviour can be changed by passing the "ssl_options" parameter with any options accepted by IO::Socket::SSL. For instance, to check that the remote host has a trusted certificate, and to avoid man-in-the-middle attacks, you could do the following:

    use Search::Elasticsearch;
    use IO::Socket::SSL;
    my $es = Search::Elasticsearch->new(
        nodes => [
            "https://node1.mydomain.com:9200",
            "https://node2.mydomain.com:9200",
        ],
        ssl_options => {
            SSL_verify_mode     => SSL_VERIFY_PEER,
            SSL_ca_file         => '/path/to/cacert.pem'
        }
    );

If the remote server cannot be verified, an Search::Elasticsearch::Error will be thrown.

If you want your client to present its own certificate to the remote server, then use:

    use Search::Elasticsearch;
    use IO::Socket::SSL;
    my $es = Search::Elasticsearch->new(
        nodes => [
            "https://node1.mydomain.com:9200",
            "https://node2.mydomain.com:9200",
        ],
        ssl_options => {
            SSL_verify_mode     => SSL_VERIFY_PEER,
            SSL_use_cert        => 1,
            SSL_ca_file         => '/path/to/cacert.pem',
            SSL_cert_file       => '/path/to/client.pem',
            SSL_key_file        => '/path/to/client.pem',
        }
    );

Methods

    ($status,$body) = $self->perform_request({
        # required
        method      => 'GET|HEAD|POST|PUT|DELETE',
        path        => '/path/of/request',
        qs          => \%query_string_params,
        # optional
        data        => $body_as_string,
        mime_type   => 'application/json',
        timeout     => $timeout
    });
