背景
項目用戶量逐漸增大，接口調用次數(shù)越來越多，所以決定使用Redis存token，緩解數(shù)據(jù)庫壓力
調研
在config/auth.php文件中發(fā)現(xiàn)用戶的驅動使用的是EloquentUserProvider服務提供器，然后查找EloquentUserProvider.php 然后發(fā)現(xiàn)在vendor/laravel/framework/src/Illuminate/Auth文件下存在該文件
?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 $query->first();
}
...
}
實現(xiàn)代碼
因為我們是需要在當前的Auth驗證基礎之上添加一層Redis緩存，所以最簡單的辦法繼承EloquentUserProvider類，重寫
retrieveByCredentials方法所以我們新建RedisUserProvider.php文件
?php
namespace App\Providers;
use Illuminate\Auth\EloquentUserProvider;
use Cache;
class RedisUserProvider extends EloquentUserProvider
{
public function __construct($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文件下修改如下代碼
public function boot(GateContract $gate)
{
$this->registerPolicies($gate);
//將redis注入Auth中
Auth::provider('redis',function($app, $config){
return new RedisUserProvider($app['hash'], $config['model']);
});
}
修改config/auth.php用戶的auth的驅動為redis。
后續(xù)
改完代碼以后發(fā)現(xiàn)無法正常登錄，一直提示用戶或密碼錯誤。。。然后看看了下用戶認證方法是
auth('web')->once($credentials);然后看是在
Illuminate\Auth\SessionGuard文件中用到了RedisUserProvider文件中retrieveByCredentials方法中對用戶進行密碼驗證，
于是修改RedisUserProvider文件
?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);
}
}
然后登錄成功啦！皆大歡喜！
