laravel8 elasticsearch 配置搭建使用

laravel 8框架  扩展elasticsearch 

 

首先 elasticsearch 的版本号 需要和 扩展的版本号对应

composer require elasticsearch/elasticsearch

 

然后是配置到common 调用文件

<?php
namespace App\Es;

use Elasticsearch\ClientBuilder;

class MyEs
{
    //ES客户端链接
    private $client;

    /**
     * 构造函数
     * MyElasticsearch constructor.
     */
    public function __construct()
    {

        　　// 带有账号、密码的客服端信息         　　$hosts = [             　　[                 　　'host' => '127.0.0.1',      // 域名                 　　'port' => '9200',           // 端口                 　　'scheme' => 'http',         // 协议                 　　'user' => 'elastic',        // 账号                 　　'pass' => '123456'        　// 密码             　　]         　　];
        　　$this->client = ClientBuilder::create()->setHosts($hosts)->build();

    }

在 其他文件中调用

 

use App\Service\Common\ElasticSearchService;

    public function elastic(){
        $keywords = $this->request->get('keywords');

        $body =  [
            'size'   => 20,

                'match' => [

                ]
            ],
            'sort' => ['_score'=>['order'=>'desc']],
        ];

        $res = resolve(ElasticSearchService::class)->search_doc('fulan','goods', $body);

        return $res;
