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();
