Laravel的Auth验证Token验证使用自定义Redis的例子

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

在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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76

<?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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

<?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文件下修改如下代码

?

1 2 3 4 5 6 7 8 9

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

?

1	auth( 'web' )->once( $credentials );然后看是在

?

1	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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49

<?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 );   } }

然后登录成功啦！皆大欢喜！
