laravel的api验证失败重定向

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！
