這篇文章主要介紹了Laravel使用scout集成elasticsearch做全文搜索的實(shí)現(xiàn)方法，小編覺(jué)得挺不錯(cuò)的，現(xiàn)在分享給大家，也給大家做個(gè)參考。一起跟隨小編過(guò)來(lái)看看吧

本文介紹了Laravel使用scout集成elasticsearch做全文搜索的實(shí)現(xiàn)方法，分享給大家，具體如下：

安裝需要的組件

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

如果composer require laravel/scout 出現(xiàn)報(bào)錯(cuò)

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），添加如下兩個(gè)provider

'providers' => [ 
    //es search 加上以下內(nèi)容 
    Laravel\Scout\ScoutServiceProvider::class, 
    ScoutEngines\Elasticsearch\ElasticsearchProvider::class, 
]

添加完成，執(zhí)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的賬號(hào):密碼@連接

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

創(chuàng)建一個(gè)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() { //創(chuàng)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);

    // 創(chuàng)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中注冊(cè)這個(gè)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
  ];

執(zhí)行這個(gè)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');
  }

}

導(dǎo)入全文索引信息

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

測(cè)試簡(jiǎn)單的全文索引

php artisan tinker

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