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

<?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

然后登录成功啦！皆大欢喜！
