当我尝试将 Cache 添加到 Slim-3“{} is not resolvable” for \Slim\HttpCache\Cache('public', 86400)

问题描述

我使用 Slim 3 制作了一个服务器端 API。现在我尝试按照 Slim 用户指南添加 HTTP 缓存，但我收到错误 "{} is not resolvable" for \Slim\HttpCache\Cache('public',86400)

这是关于我的代码的一些信息：

$app = new Slim\App(['settings' => $config]); //$config is the configuration of my DB
$container = $app->getContainer();
$container['cache'] = function () {
    return new \Slim\HttpCache\CacheProvider();
};

$app->add(new \Slim\HttpCache\Cache('public',86400));

我当然是执行 bash 命令 composer require slim/http-cache 来安装 http 缓存。我还按照用户指南中的说明将我的 PHP.ini 设置“session.cache_limiter”设置为空字符串。

我不知道我缺少什么以及有什么问题，所以如果您有任何想法，请帮忙！

这是我收到的完整错误消息：
