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
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();
