NAME Search::Elasticsearch::Cxn::NetCurl - A Cxn implementation which uses libcurl via Net::Curl VERSION version 7.715 DESCRIPTION Provides an HTTP Cxn class based on Net::Curl. The "NetCurl" Cxn class is very fast and uses persistent connections but requires XS and "libcurl". This class does Search::Elasticsearch::Role::Cxn, whose documentation provides more information. CONFIGURATION "connect_timeout" Unlike most HTTP backends, Net::Curl accepts a separate "connect_timeout" parameter, which defaults to 2 seconds but can be reduced in an environment with low network latency. Inherited configuration From Search::Elasticsearch::Role::Cxn * node * max_content_length * deflate * deflate * request_timeout * ping_timeout * dead_timeout * max_dead_timeout * sniff_request_timeout * sniff_timeout * handle_args * handle_args SSL/TLS Search::Elasticsearch::Cxn::NetCurl does no validation of remote hosts by default. This behaviour can be changed by passing the "ssl_options" parameter with any options accepted by Net::Curl (see ). 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 Net::Curl::Easy qw( CURLOPT_CAINFO ); my $es = Search::Elasticsearch->new( cxn => 'NetCurl', nodes => [ "https://node1.mydomain.com:9200", "https://node2.mydomain.com:9200", ], ssl_options => { CURLOPT_CAINFO() => '/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 Net::Curl::Easy qw( CURLOPT_CAINFO CURLOPT_SSLCERT CURLOPT_SSLKEY ); my $es = Search::Elasticsearch->new( cxn => 'NetCurl', nodes => [ "https://node1.mydomain.com:9200", "https://node2.mydomain.com:9200", ], ssl_options => { CURLOPT_CAINFO() => '/path/to/cacert.pem' CURLOPT_SSLCERT() => '/path/to/client.pem', CURLOPT_SSLKEY() => '/path/to/client.pem', } ); METHODS "perform_request()" ($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 }); Sends the request to the associated Elasticsearch node and returns a $status code and the decoded response $body, or throws an error if the request failed.
