Laravel的Auth验证Token验证使用自定义Redis的例子

时间:2021-08-25 14:48     来源/作者:llllllwwwww

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

<?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

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

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!
