小編給大家分享一下Laravel中Auth驗證Token驗證如何使用自定義Redis,希望大家閱讀完這篇文章之后都有所收獲,下面讓我們一起去探討吧!
背景
項目用戶量逐漸增大,接口調用次數越來越多,所以決定使用Redis存token,緩解數據庫壓力
調研
在config/auth.php文件中發現用戶的驅動使用的是EloquentUserProvider服務提供器,然后查找EloquentUserProvider.php 然后發現在vendor/laravel/framework/src/Illuminate/Auth文件下存在該文件
<?php namespace Illuminate\Auth; use Illuminate\Support\Str; use Illuminate\Contracts\Auth\UserProvider; use Illuminate\Contracts\Hashing\Hasher as HasherContract; use Illuminate\Contracts\Auth\Authenticatable as UserContract; class EloquentUserProvider implements UserProvider { /** * The hasher implementation. * * @var \Illuminate\Contracts\Hashing\Hasher */ protected $hasher; /** * The Eloquent user model. * * @var string */ protected $model; /** * Create a new database user provider. * * @param \Illuminate\Contracts\Hashing\Hasher $hasher * @param string $model * @return void */ public function __construct(HasherContract $hasher, $model) { $this->model = $model; $this->hasher = $hasher; } /** * Retrieve a user by their unique identifier. * * @param mixed $identifier * @return \Illuminate\Contracts\Auth\Authenticatable|null */ public function retrieveById($identifier) { return $this->createModel()->newQuery()->find($identifier); } ... /** * Retrieve a user by the given credentials. * * @param array $credentials * @return \Illuminate\Contracts\Auth\Authenticatable|null */ public function retrieveByCredentials(array $credentials) { if (empty($credentials)) { return; } // First we will add each credential element to the query as a where clause. // Then we can execute the query and, if we found a user, return it in a // Eloquent User "model" that will be utilized by the Guard instances. $query = $this->createModel()->newQuery(); foreach ($credentials as $key => $value) { if (! Str::contains($key, 'password')) { $query->where($key, $value); } } return $query->first(); } ... }
實現代碼
因為我們是需要在當前的Auth驗證基礎之上添加一層Redis緩存,所以最簡單的辦法繼承EloquentUserProvider類,重寫
retrieveByCredentials方法所以我們新建RedisUserProvider.php文件
<?php namespace App\Providers; use Illuminate\Auth\EloquentUserProvider; use Cache; class RedisUserProvider extends EloquentUserProvider { public function __construct($hasher, $model) { parent::__construct($hasher, $model); } /** * Retrieve a user by the given credentials. * * @param array $credentials * @return \Illuminate\Contracts\Auth\Authenticatable|null */ public function retrieveByCredentials(array $credentials) { if (!isset($credentials['token'])) { return; } $token = $credentials['token']; $redis = Cache::getRedis(); $userId = $redis->get($token); return $this->retrieveById($userId); } }
然后在AuthServiceProvider.php文件下修改如下代碼
public function boot(GateContract $gate) { $this->registerPolicies($gate); //將redis注入Auth中 Auth::provider('redis',function($app, $config){ return new RedisUserProvider($app['hash'], $config['model']); }); }
修改config/auth.php用戶的auth的驅動為redis。
后續
改完代碼以后發現無法正常登錄,一直提示用戶或密碼錯誤。。。然后看看了下用戶認證方法是
auth('web')->once($credentials);然后看是在
Illuminate\Auth\SessionGuard文件中用到了RedisUserProvider文件中retrieveByCredentials方法中對用戶進行密碼驗證,
于是修改RedisUserProvider文件
<?php namespace App\Providers; use Illuminate\Auth\EloquentUserProvider; use Illuminate\Support\Str; use Illuminate\Contracts\Auth\Authenticatable as UserContract; use Cache; class RedisUserProvider extends EloquentUserProvider { public function __construct($hasher, $model) { parent::__construct($hasher, $model); } /** * Retrieve a user by the given credentials. * * @param array $credentials * @return \Illuminate\Contracts\Auth\Authenticatable|null */ public function retrieveByCredentials(array $credentials) { if (empty($credentials)) { return; } if(isset($credentials['phone']) && isset($credentials['password'])){ // First we will add each credential element to the query as a where clause. // Then we can execute the query and, if we found a user, return it in a // Eloquent User "model" that will be utilized by the Guard instances. $query = $this->createModel()->newQuery(); foreach ($credentials as $key => $value) { if (! Str::contains($key, 'password')) { $query->where($key, $value); } } return $query->first(); } $token = $credentials['token']; $redis = Cache::getRedis(); $userId = $redis->get($token); return $this->retrieveById($userId); } }
