項目用戶量逐漸增大,接口調用次數愈來愈多,因此決定使用Redis存token,緩解數據庫壓力php
我用的的laravel是5.2版本。在config/auth.php文件中發現用戶的驅動使用的是eloquent,而後查找EloquentUserProvider.php 而後發如今vendor/laravel/framework/src/Illuminate/Auth文件下存在該文件html
<?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 $query->first(); } ... }
由於咱們是須要在當前的Auth驗證基礎之上添加一層Redis緩存,因此最簡單的辦法繼承EloquentUserProvider類,重寫
laravel
retrieveByCredentials方法因此咱們新建RedisUserProvider.php文件
<?php namespace App\Providers; use Illuminate\Auth\EloquentUserProvider; use Cache; class RedisUserProvider extends EloquentUserProvider { public function __construct($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); } }
而後在AuthServiceProvider.php文件下修改以下代碼web
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'], $config['model']); }); }
修改config/auth.php用戶的auth的驅動爲redis。redis
改完代碼之後發現沒法正常登陸,一直提示用戶或密碼錯誤。。。而後看看了下用戶認證方法是數據庫
auth('web')->once($credentials);而後看是在
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,因而修改RedisUserProvider文件緩存
<?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); } }
