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

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'], $config['model']); });} |
修改config/auth.php用户的auth的驱动为redis。
后续
改完代码以后发现无法正常登录，一直提示用户或密码错误。。。然后看看了下用户认证方法是
|
1
|
auth('web')->once($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

然后登录成功啦！皆大欢喜！
以上这篇Laravel的Auth验证Token验证使用自定义Redis的例子就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持服务器之家。
