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

代码语言:javascript复制
composer require tamayo/laravel-scout-elastic
composer require laravel/scout 

如果composer require laravel/scout 出现报错

代码语言:javascript复制
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

代码语言:javascript复制
composer require laravel/scout ^5.0

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

代码语言:javascript复制
'providers' =  [ 
    //es search 加上以下内容 
    LaravelScoutScoutServiceProvider::class, 
    ScoutEnginesElasticsearchElasticsearchProvider::class, 
]

添加完成,执行命令,生成config文件

代码语言:javascript复制
php artisan vendor:publish --provider="LaravelScoutScoutServiceProvider"

修改config/scout.php

代码语言:javascript复制
  '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

代码语言:javascript复制
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

代码语言:javascript复制
<?php
namespace AppConsoleCommands;
use GuzzleHttpClient;
use IlluminateConsoleCommand;

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

代码语言:javascript复制
<?php

namespace AppConsole;

use AppConsoleCommandsESInit;
use IlluminateConsoleSchedulingSchedule;
use IlluminateFoundationConsoleKernel 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

代码语言:javascript复制
php artisan es:init

修改model支持 全文搜索

代码语言:javascript复制
<?php
namespace AppActivityNewsModel;

use AppModelCategory;
use AppStarModelStar;
use IlluminateDatabaseEloquentModel;
use LaravelScoutSearchable;


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

代码语言:javascript复制
php artisan scout:import "AppActivityNewsModelActivityNews"

测试简单的全文索引

代码语言:javascript复制
php artisan tinker

    AppActivityNewsModelActivityNews::search('略懂皮毛')- get();
