NAME
Search::Elasticsearch::Cxn::Mojo - An async Cxn implementation which uses Mojo::UserAgent
VERSION
version 7.714
DESCRIPTION
Provides an async HTTP Cxn class based on Mojo::UserAgent. The Mojo 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, Search::Elasticsearch::Role::Async::Cxn, and Search::Elasticsearch::Role::Is_Async.
CONFIGURATION
connect_timeout
Unlike most HTTP backends, Mojo::UserAgent 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
SSL/TLS
Search::Elasticsearch::Cxn::Mojo does no validation of the remote host by default.
This behaviour can be changed by passing the ssl_options parameter with the ca, cert, and key options. 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::Async;
my $es = Search::Elasticsearch::Async->new(
cxn => 'Mojo',
nodes => [
"https://node1.mydomain.com:9200",
"https://node2.mydomain.com:9200",
],
ssl_options => {
ca => '/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::Async;
my $es = Search::Elasticsearch::Async->new(
cxn => 'Mojo',
nodes => [
"https://node1.mydomain.com:9200",
"https://node2.mydomain.com:9200",
],
ssl_options => {
ca => '/path/to/cacert.pem'
cert => '/path/to/client.pem',
key => '/path/to/client.pem'
}
);METHODS
perform_request()
$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 => $timeout
})
->then(sub { my ($status,body) = @_; ...})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.
