Laravel使用scout集成elasticsearch做全文搜索的实现方法

本文介绍了Laravel使用scout集成elasticsearch做全文搜索的实现方法，分享给大家，具体如下：

安装需要的组件

composer require tamayo/laravel-scout-elastic
composer require laravel/scout 

如果composer require laravel/scout 出现报错

Using version ^6.1 for laravel/scout
./composer.json has been updated
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

 Problem 1
 - tamayo/laravel-scout-elastic 4.0.0 requires laravel/scout ^5.0 -> satisfiable by laravel/scout[5.0.x-dev].
 - tamayo/laravel-scout-elastic 4.0.0 requires laravel/scout ^5.0 -> satisfiable by laravel/scout[5.0.x-dev].
 - tamayo/laravel-scout-elastic 4.0.0 requires laravel/scout ^5.0 -> satisfiable by laravel/scout[5.0.x-dev].
 - Conclusion: don't install laravel/scout 5.0.x-dev
 - Installation request for tamayo/laravel-scout-elastic ^4.0 -> satisfiable by tamayo/laravel-scout-elastic[4.0.0].


Installation failed, reverting ./composer.json to its original content.

那么使用命令

composer require laravel/scout ^5.0

修改一下配置文件（config/app.php），添加如下两个provider

'providers' => [ 
 //es search 加上以下内容 
 Laravel\Scout\ScoutServiceProvider::class, 
 ScoutEngines\Elasticsearch\ElasticsearchProvider::class, 
]

添加完成，执行命令，生成config文件

php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"

修改config/scout.php

 'driver' => env('SCOUT_DRIVER', 'elasticsearch'),

 'elasticsearch' => [
 'index' => env('ELASTICSEARCH_INDEX', '你的Index名字'),
 'hosts' => [
 env('ELASTICSEARCH_HOST', ''),
 ],
 ],

在.env 配置ES的 账号:密码@连接

ELASTICSEARCH_HOST=elastic:密码@你的域名.com:9200

创建一个生成mapping的命令行文件，到 app/Console/Commands

<?php
namespace App\Console\Commands;
use GuzzleHttp\Client;
use Illuminate\Console\Command;

class ESInit extends Command {

 protected $signature = 'es:init';

 protected $description = 'init laravel es for news';

 public function __construct() { parent::__construct(); }

 public function handle() { //创建template
 $client = new Client(['auth'=>['elastic', 'Wangcai5388']]);
 $url = config('scout.elasticsearch.hosts')[0] . '/_template/news';
 $params = [
 'json' => [
 'template' => config('scout.elasticsearch.index'),
 'settings' => [
 'number_of_shards' => 5
 ],
 'mappings' => [
 '_default_' => [
 'dynamic_templates' => [
 [
 'strings' => [
 'match_mapping_type' => 'string',
 'mapping' => [
 'type' => 'text',
 'analyzer' => 'ik_smart',
 'ignore_above' => 256,
 'fields' => [
 'keyword' => [
 'type' => 'keyword'
 ]
 ]
 ]
 ]
 ]
 ]
 ]
 ]
 ]
 ];
 $client->put($url, $params);

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

 $params = [
 'json' => [
 'settings' => [
 'refresh_interval' => '5s',
 'number_of_shards' => 5,
 'number_of_replicas' => 0
 ],
 'mappings' => [
 '_default_' => [
 '_all' => [
 'enabled' => false
 ]
 ]
 ]
 ]
 ];
 $client->put($url, $params);

 }
}

在kernel中注册这个命令

<?php

namespace App\Console;

use App\Console\Commands\ESInit;
use Illuminate\Console\Scheduling\Schedule;
use Illuminate\Foundation\Console\Kernel as ConsoleKernel;

class Kernel extends ConsoleKernel
{
 /**
 * The Artisan commands provided by your application.
 *
 * @var array
 */
 protected $commands = [
 ESInit::class
 ];

执行这个命令 生成 mapping

php artisan es:init

修改model支持 全文搜索

<?php
namespace App\ActivityNews\Model;

use App\Model\Category;
use App\Star\Model\Star;
use Illuminate\Database\Eloquent\Model;
use Laravel\Scout\Searchable;


class ActivityNews extends Model
{
 use Searchable;

 protected $table = 'activity_news';
 protected $fillable = [
 'type_id',
 'category_id',
 'title',
 'sub_title',
 'thumb',
 'intro',
 'star_id',
 'start_at',
 'end_at',
 'content',
 'video_url',
 'status',
 'is_open',
 'is_top',
 'rank',
 ];

 public function star()
 {
 return $this->hasOne(Star::class, 'id', 'star_id');
 }

 public function category()
 {
 return $this->hasOne(Category::class, 'id', 'category_id');
 }

 public static function getActivityIdByName($name)
 {
 return self::select('id')
 ->where([
 ['status', '=', 1],
 ['type_id', '=', 2],
 ['title', 'like', '%' . $name . '%']
 ])->get()->pluck('id');
 }

}

导入全文索引信息

php artisan scout:import "App\ActivityNews\Model\ActivityNews"

测试简单的全文索引

php artisan tinker

>>> App\ActivityNews\Model\ActivityNews::search('略懂皮毛')->get();
