Elasticsearch with PHP connection not working

Question

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

`[Thu Mar 31 22:07:09 2022] 127.0.0.1:44396 [500]: GET / - Uncaught Elastic\Elasticsearch\Exception\ClientResponseException: 404 Not Found: <!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

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);

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);

I have tried this approach too.

Is the response exactly the same? Is your elasticsearch positively running on the same machine as the webserver?

Yes I am running locally. Elastic search is running in 9200 port. And php in 8000. I am getting result using curl and also in postman
