Laravel的Auth验证Token验证使用自定义Redis的例子

易采站长站,站长之家为您整理了Laravel的Auth验证Token验证使用自定义Redis的例子的相关内容。

背景

项目用户量逐渐增大,接口调用次数越来越多,所以决定使用Redis存token,缓解数据库压力

调研

config/auth.php文件中发现用户的驱动使用的是EloquentUserProvider服务提供器,然后查找EloquentUserProvider.php 然后发现在vendor/laravel/framework/src/Illuminate/Auth文件下存在该文件

<?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(); }...}

实现代码

因为我们是需要在当前的Auth验证基础之上添加一层Redis缓存,所以最简单的办法继承EloquentUserProvider类,重写

retrieveByCredentials方法所以我们新建RedisUserProvider.php文件

<?phpnamespace 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文件下修改如下代码

 public function boot(GateContract $gate) {  $this->registerPolicies($gate);   //将redis注入Auth中  Auth::provider('redis',function($app, $config){   return new RedisUserProvider($app['hash'], $config['model']);  }); }

修改config/auth.php用户的auth的驱动为redis。

后续

改完代码以后发现无法正常登录,一直提示用户或密码错误。。。然后看看了下用户认证方法是

auth('web')->once($credentials);然后看是在
Illuminate\Auth\SessionGuard文件中用到了RedisUserProvider文件中retrieveByCredentials方法中对用户进行密码验证,

于是修改RedisUserProvider文件

<?phpnamespace 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); }}

然后登录成功啦!皆大欢喜!
