Elasticsearch with PHP connection not working-CodePudding

I am using Elasticsearch 8.1. It is running on port 9200. When I execute from POSTMAN,

https://localhost:9200/learn/_search

with Authorization: Type: Basic Auth and username & password, I can see the result.

But now I want to implement this using PHP. I have installed "elasticsearch/elasticsearch": "^8.0" in my composer. This is the code I have tried.

use Elastic\Elasticsearch\ClientBuilder;

$hosts = [
    'host' => 'localhost',
    'port' => '9200',
    'scheme' => 'https',
    'user' => 'elastic',
    'pass' => 'LisRrIul9oMKh2deJkMv'
];

$client = ClientBuilder::create()
    ->setHosts($hosts)
    ->build();


$params = [
    'index' => 'learn',
];

$results = $client->search($params);

echo "<pre>";
print_r($results);

I am getting

CodePudding user response：

There seems to be something wrong with your ClientBuilder call, since the response indicates that at least the port setting did not work (as it contains localhost Port 80).

Try passing the parameters in one URL string:

$hosts = ['https://elastic:LisRrIul9oMKh2deJkMv@localhost:9200'];

To then get the indices, you can use cat instead of search:

$indices = $client->cat()->indices($params);

Try this

$client = ClientBuilder::create()
    ->setBasicAuthentication('elastic', 'LisRrIul9oMKh2deJkMv')
    ->setCABundle('/etc/elasticsearch/certs/http_ca.crt')
    ->setHosts(['https://localhost:9200'])
    ->build();

$params = [
    'index' => 'learn',
];

$results = $client->search($params);
