PHP 如何使用 Elasticsearch API接口

一、实战场景

如何在 PHP 中使用 Elasticsearch API 接口

二、知识点

• PHP
• Elasticsearch
• Restful 接口

三、菜鸟实战

1、安装 Elasticsearch 官方 PHP SDK

​​https://github.com/elastic/elasticsearch-php​​​

composer require elasticsearch/elasticsearch
composer require elasticsearch/elasticsearch

2、创建​

use Elastic\Elasticsearch\ClientBuilder;

public function info(Request $request){

    // 初始化
    $client = ClientBuilder::create()

        ->setHosts(['localhost:9200'])

        ->build();

    $response = $client->info();

    // 响应格式化
    $info = $response->asArray();

    $data = [
        'es_info' => $info,
    ];

    $this->success($data);
}

3、执行返回结果

{
    "code": 0,
    "message": "ok",
    "data": {
        "es_info": {
            "name": "xqdsvtvnyje9zxeo",
            "cluster_name": "elasticsearch",
            "cluster_uuid": "tNPisFAxTVaRdXHKATIUWQ",
            "version": {
                "number": "8.5.1",
                "build_flavor": "default",
                "build_type": "tar",
                "build_hash": "c1310c45fc534583afe2c1c03046491efba2bba2",
                "build_date": "2022-11-09T21:02:20.169855900Z",
                "build_snapshot": false,
                "lucene_version": "9.4.1",
                "minimum_wire_compatibility_version": "7.17.0",
                "minimum_index_compatibility_version": "7.0.0"
            },
            "tagline": "You Know, for Search"
        }
    }
}

通过上述步骤，就将 php 与 Elasticsearch 连通了，接下来使用 sdk 中的 api 即可。
