今天小編就為大家分享一篇Laravel的Auth驗證Token驗證使用自定義Redis的例子，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

背景

項目用戶量逐漸增大，接口調(diào)用次數(shù)越來越多，所以決定使用Redis存token，緩解數(shù)據(jù)庫壓力

調(diào)研

在config/auth.php文件中發(fā)現(xiàn)用戶的驅(qū)動使用的是EloquentUserProvider服務(wù)提供器，然后查找EloquentUserProvider.php 然后發(fā)現(xiàn)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(xiàn)代碼

因為我們是需要在當(dāng)前的Auth驗證基礎(chǔ)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(qū)動為redis。

后續(xù)

改完代碼以后發(fā)現(xiàn)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);
 }
}

然后登錄成功啦！皆大歡喜！
