如何在slim 3中使用缓存系统(memcached、redis或任何其他)

composer require slim/slim "^3.0"

// 配置Memcached
$settings['cache'] = [
    'type' => 'memcached',
    'host' => 'localhost',
    'port' => 11211,
    'prefix' => 'slim_'
];

// 配置Redis
$settings['cache'] = [
    'type' => 'redis',
    'host' => 'localhost',
    'port' => 6379,
    'prefix' => 'slim_'
];

// 初始化Memcached
$container['cache'] = function ($c) {
    $settings = $c->get('settings')['cache'];
    $memcached = new \Memcached();
    $memcached->addServer($settings['host'], $settings['port']);
    $cache = new \Slim\HttpCache\CacheProvider($memcached, $settings['prefix']);
    return $cache;
};

// 初始化Redis
$container['cache'] = function ($c) {
    $settings = $c->get('settings')['cache'];
    $redis = new \Redis();
    $redis->connect($settings['host'], $settings['port']);
    $cache = new \Slim\HttpCache\CacheProvider($redis, $settings['prefix']);
    return $cache;
};

$app->get('/example', function ($request, $response, $args) {
    $cache = $this->get('cache');
    $key = 'example_key';
    
    // 尝试从缓存中获取数据
    $data = $cache->get($key);
    
    if ($data === false) {
        // 如果缓存中不存在数据，则从数据库或其他来源获取数据
        $data = fetchDataFromDatabase();
        
        // 将数据存储到缓存中，设置过期时间（可选）
        $cache->set($key, $data, 3600); // 缓存有效期为1小时
    }
    
    // 使用数据进行响应
    return $response->withJson($data);
});
