你是否在檢索千百萬級數據時爲性能和速度而擔心呢,即便優化了sql,建立了數據庫索引,仍是不盡如人意呢?
下面就主要介紹laravel如何集成Algoliaphp
Algolia是法國初創公司爲你提供毫秒級的數據庫實時搜索服務,天下武功無堅不摧,惟快不破。記住哦,是毫秒級。html
本文基於laravel5.5,其餘版本大同小異。laravel
composer require laravel/scout composer require algolia/algoliasearch-client-php
前往https://www.algolia.com/ 註冊帳號,初學者可使用免費版,而後在帳戶的API Keys菜單獲取Application ID和Admin API Key,後面會用到sql
在config/app.php文件中的providers數組中加入服務提供者數據庫
// Scout全文搜索 Laravel\Scout\ScoutServiceProvider::class,
使用如下命令生成scout配置文件api
php artisan vendor:publish --provider="Laravel\Scout\ScoutServiceProvider"
該命令會自動生成config/scout.php文件,而後咱們打開.env文件,加入scout的配置數組
# scout配置 SCOUT_DRIVER=algolia SCOUT_PREFIX= # algolia的Application ID ALGOLIA_APP_ID=xxxxxxxxxx # algolia的Admin API Key ALGOLIA_SECRET=xxxxxxxxxxxxxxxxxxxxxxxxxx
建立模型app/Student.php,爲方便後續測試,請先建表和填充數據,能夠手動使用sql語句添加數據,也使用laravel自動的數據遷移和填充,能夠參考 https://www.tech1024.cn/origi...網絡
<?php namespace App; use Illuminate\Database\Eloquent\Model; use Laravel\Scout\Searchable; /** * 學生模型 */ class Student extends Model { use Searchable; /** * 索引名稱 * * @return string */ public function searchableAs() { return 'students_index'; } /** * 可搜索的數據索引 * * @return array */ public function toSearchableArray() { $array = $this->toArray(); // Customize array... return $array; } }
php artisan scout:import "App\Student"
可能會報以下錯誤app
[AlgoliaSearch\AlgoliaConnectionException] Hosts unreachable: Resolving timed out after 1000 milliseconds,Resolving timed out after 1000 milliseconds,Resolving timed out after 3000 milliseconds,Resolving tim ed out after 3000 milliseconds
這是因爲默認algoliasearch-client配置的鏈接超時時間爲1秒,因爲網絡速度的緣由,咱們能夠把鏈接時間修改一下
建立app/Services/Scout/EngineManager.php文件以下composer
<?php namespace App\Services\Scout; use AlgoliaSearch\Client as Algolia; use AlgoliaSearch\Version as AlgoliaUserAgent; use Laravel\Scout\EngineManager as BaseEngineManager; use Laravel\Scout\Engines\AlgoliaEngine; /** * */ class EngineManager extends BaseEngineManager { public function createAlgoliaDriver() { AlgoliaUserAgent::addSuffixUserAgentSegment('Laravel Scout', '3.0.7'); $algolia = new Algolia( config('scout.algolia.id'), config('scout.algolia.secret') ); // 設置鏈接超時時間 $algolia->setConnectTimeout(30, 30, 30); return new AlgoliaEngine($algolia); } }
打開app/Providers/AppServiceProvider.php,在boot()中加入如下代碼
public function boot() { // …… 省略以前代碼 $this->app->singleton(\Laravel\Scout\EngineManager::class, function ($app) { return new \App\Services\Scout\EngineManager($app); }); }
是否是導入成功了呢?
php artisan scout:import "App\Student" Imported [App\Student] models up to ID: 500 Imported [App\Student] models up to ID: 1000 Imported [App\Student] models up to ID: 1500 Imported [App\Student] models up to ID: 2000 Imported [App\Student] models up to ID: 2500 Imported [App\Student] models up to ID: 3000 Imported [App\Student] models up to ID: 3500 Imported [App\Student] models up to ID: 4000 Imported [App\Student] models up to ID: 4500 Imported [App\Student] models up to ID: 5000 Imported [App\Student] models up to ID: 5500 Imported [App\Student] models up to ID: 6000 Imported [App\Student] models up to ID: 6500 Imported [App\Student] models up to ID: 7000 Imported [App\Student] models up to ID: 7500 Imported [App\Student] models up to ID: 8000 Imported [App\Student] models up to ID: 8500 Imported [App\Student] models up to ID: 9000 Imported [App\Student] models up to ID: 9500 Imported [App\Student] models up to ID: 10000 All [App\Student] records have been imported.
在https://www.algolia.com帳戶後... 的菜單中已經有了剛剛導入的students_index索引數據
$studens = App\Student::search('成燕')->get(); dd($studens);
能夠填充個百萬條數據試試,檢索速度,是否是比直接查詢數據庫要快不少呢?
更多用法請查閱官方文檔 https://www.algolia.com/doc/a...
不過筆者並不推薦使用algolia檢索引擎,畢竟國內的網速太慢,後續筆者會退出laravel和elasticsearch、sphinx相關的資料,請繼續關注。
