laravel Scout使用elasticsearch搜索引擎

Laravel Scout 是针对Eloquent 模型开发的一个简单的，基于驱动的全文检索系统。Scout 使用模型观察者时会自动保持你的检索索引与你的 Eloquent 记录同步。
目前，Scout 带着一个Algolia驱动；然而，扩展 Scout 并不难，你可以通过自定义驱动来自由的扩展 Scout。Scout的使用请看文档Scout 全文搜索

docker安装elasticsearch

docker run -d --name es -v /Users/chen/data/docker/es:/data/es -v /Users/chen/data/docker/es/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" elasticsearch:6.8.5

主要参数说明：
-d 后台守护进程
--name 为容器命名
-v 挂载文件，这里是把当前宿主机的目录 挂载到容器的项目目录上

elasticsearch.yml 文件内容

cluster.name: "docker-cluster"
network.host: 0.0.0.0

path.data: /data/es/data

http.cors.enabled: true
http.cors.allow-origin: "*"

浏览器访问：http://127.0.0.1:9200 就能看到es版本信息

Scout配置文件

//config/scout.php文件中添加下面代码

//这里是添加的代码
    'elasticsearch' => [
        'index' => env('ELASTICSEARCH_INDEX', 'laravel1'),
        'hosts' => [
            env('ELASTICSEARCH_HOST', 'http://127.0.0.1:9200'),
        ],
    ],

创建es索引

php artisan make:command ESInitUser

<?php

namespace App\Console\Commands;

use GuzzleHttp\Client;
use Illuminate\Console\Command;

class ESInitUser extends Command
{
   /**
    * The name and signature of the console command.
    *
    * @var string
    */
   protected $signature = 'es:init:user';

   /**
    * The console command description.
    *
    * @var string
    */
   protected $description = 'Command description';

   /**
    * Create a new command instance.
    *
    * @return void
    */
   public function __construct()
   {
       parent::__construct();
   }

   /**
    * Execute the console command.
    *
    * @return mixed
    */
   public function handle()
   {
       //创建template
       $client = new Client();

       $url = config('scout.elasticsearch.hosts')[0] . '/_template/users';

                           ]

model代码

需要修改model里的代码

/**
 * App\Models\User
 *
 * @property int $id
 * @property string $username 用户名
 * @property string $createtime 创建时间
 */
class User extends Model
{
    use Searchable;
    public function searchableAs()
    {
        // 对应es里的_type，相当于mysql表的概念
        return 'users_index';
    }

    public function toSearchableArray()
    {
        $array = $this->toArray();
        return $array;
    }
}

导入数据

php artisan scout:import "\App\Models\User"
