NAME

6       Search::Elasticsearch::Cxn::LWP - A Cxn implementation which uses LWP
7

VERSION

9       version 7.30
10

DESCRIPTION

12       Provides an HTTP Cxn class and based on LWP.  The LWP backend uses pure
13       Perl and persistent connections.
14
15       This class does Search::Elasticsearch::Role::Cxn, whose documentation
16       provides more information, and Search::Elasticsearch::Role::Is_Sync.

SSL/TLS

47       Search::Elasticsearch::Cxn::LWP uses IO::Socket::SSL to support HTTPS.
48       By default, no validation of the remote host is performed.
49
50       This behaviour can be changed by passing the "ssl_options" parameter
51       with any options accepted by IO::Socket::SSL. For instance, to check
52       that the remote host has a trusted certificate, and to avoid man-in-
53       the-middle attacks, you could do the following:
54
55           use Search::Elasticsearch;
56
57           my $es = Search::Elasticsearch->new(
58               cxn   => 'LWP',
59               nodes => [
60                   "https://node1.mydomain.com:9200",
61                   "https://node2.mydomain.com:9200",
62               ],
63               ssl_options => {
64                   verify_hostname     => 1,
65                   SSL_ca_file         => '/path/to/cacert.pem'
66               }
67           );
68
69       If the remote server cannot be verified, an
70       Search::Elasticsearch::Error will be thrown - LWP does not allow us to
71       detect that the connection error was due to invalid SSL.
72
73       If you want your client to present its own certificate to the remote
74       server, then use:
75
76           use Search::Elasticsearch;
77
78           my $es = Search::Elasticsearch->new(
79               cxn   => 'LWP',
80               nodes => [
81                   "https://node1.mydomain.com:9200",
82                   "https://node2.mydomain.com:9200",
83               ],
84               ssl_options => {
85                   verify_hostname     => 1,
86                   SSL_ca_file         => '/path/to/cacert.pem',
87                   SSL_use_cert        => 1,
88                   SSL_cert_file       => '/path/to/client.pem',
89                   SSL_key_file        => '/path/to/client.pem',
90               }
91           );

METHODS

94   "perform_request()"
95           ($status,$body) = $self->perform_request({
96               # required
97               method      => 'GET|HEAD|POST|PUT|DELETE',
98               path        => '/path/of/request',
99               qs          => \%query_string_params,
100
101               # optional
102               data        => $body_as_string,
103               mime_type   => 'application/json',
104               timeout     => $timeout
105           });
106
107       Sends the request to the associated Elasticsearch node and returns a
108       $status code and the decoded response $body, or throws an error if the
109       request failed.
