laravel8 实现ES7.15简单使用

1.下载laravel8 支持的es插件

composer require elasticsearch/elasticsearch

2.在要使用的地方引入ES

use ElasticsearchClientBuilder;

3.生成ES对象

$client = ClientBuilder::create()‐>setHosts('连接地址')‐>build();

4.添加信息到es

      $client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
        //测试数据
        $data=[
            'id' => 2,
            'username' => '小方',
            'password' => '111111',
        ];
        //拼接数据
        $params = [
            'index' => 'test',
            'type' => '_doc',
            'id' => $data['id'],
            'body' => $data
        ];
        //存储到es中
        $response = $client->index($params);
        return $response;

 5.生成es索引

        $client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
        // 创建索引
        $params = [
            'index' => 'test',
            'body' => [
                'settings' => [
                    'number_of_shards' => 5,
                    'number_of_replicas' => 1
                ],
                'mappings' => [
                    'properties' => [
                        'fang_name' => [

                            'type' => 'text'
                        ]
                    ]
                ]
            ]
        ];
        $response = $client->indices()->create($params);
//        print_r($response);

6.搜索内容

$client = ClientBuilder::create()->setHosts(['127.0.0.1:9200'])->build();
        $keyWord='小方';
        $params = [
            'index' => 'test',
            'type' => '_doc',
            'body' => [
                'query' => [
                    'match' => [
                        'username'=>[
                            'query' => $keyWord
                        ]
                    ]
                ],
                'highlight'=>[
                    'fields'=>[
                        'fang_name'=>[
                            'pre_tags'=>[
                                ''
                            ],
                            'post_tags'=>[
                                ''
                            ]
                        ]
                    ]
                ]
            ]
        ];
        $results = $client->search($params);
        foreach ($results['hits']['hits'] as $key => $item)
        {
            $results['hits']['hits'][$key]['_source']['username'] = $item['highlight']                ['username'][$key];
        }
        $results = array_column($results['hits']['hits'], '_source');
        return $results;

7.修改es内容

$data=[
            'id' => 2,
            'username' => '小方啊',
            'password' => '222222',
        ];
        $params = [
            'index' => 'test',
            'type' => '_doc',
            'id' => $data['id'],
            'body' => [
                'username' => $data['username'],
                'password' => $data['password'],
            ],
        ];
        $response = $client->index($params);
        return $response;

8.删除es数据

        $data=[
            'id' => 2,
            'username' => '小方啊',
            'password' => '222222',
        ];
        $params = [
            'index' => 'test',
            'type' => '_doc',
            'id' => $data['id'],
        ];
        $response = $client->delete($params);
        return $response;
