Laravel的缓存驱动

数据库配置

config/database.php

'app' => [

        'client' => env('REDIS_CLIENT', 'predis'),

        'options' => [
            'cluster' =>'redis',
            'prefix' => 'app:',
        ],

        'default' => [
            'url' => env('APP_REDIS_URL'),
            'host' => env('APP_REDIS_HOST', '127.0.0.1'),
            'password' => env('APP_REDIS_PASSWORD', null),
            'port' => env('APP_REDIS_PORT', 6379),
            'database' => env('APP_REDIS_DB', 2),
        ],

    ],

缓存配置

config/cache.php

'app' => [
            'driver' => 'app',
            'connection' => 'default',
            'prefix' => '',
        ],

服务容器注册

Providers/AppServiceProvider

    /**
     * 运行于所有应用.
     *
     * @return void
     */
    public function boot()
    {
        Cache::extend('app', function ($config) {
            $redis = $this->app['app-redis'];

            $connection = $config['connection'] ?? 'default';

            return $this->repository(new RedisStore($redis, $config['prefix'] ?? '', $connection));
        });
    }

    /**
     * 注册服务提供.
     *
     * @return void
     */
    public function register()
    { 
        // 前后端共享的缓存驱动
        $this->app->singleton('app-redis', function ($app) {
            $config = $app->make('config')->get('database.app', []);

            return new RedisManager($app, Arr::pull($config, 'client', 'phpredis'), $config);
        });
    }

用法

// 缓存
cache()->store('app')->get($key);
// redis
$redis = cache()->store('app')->getRedis();
$redis->sadd($key, 1);
