Phalcon中间件：为应用程序添加异常处理和错误日志记录功能

use PhalconMvcMicro;

$app = new Micro();

// 启用中间件
$app->before(new MyMiddleware());

$app->get('/', function () {
    echo 'Hello, Phalcon!';
});

$app->after(new MyMiddleware());

$app->handle();

use PhalconMvcMicroMiddlewareInterface;
use PhalconHttpResponseInterface;

    public function beforeHandleRoute()
    {
        // 在路由处理之前触发的逻辑
    }

    public function call(Micro $app): bool
    {
        // 在路由处理之后触发的逻辑
        try {
            $app->next();
        } catch (Exception $e) {
            // 异常处理逻辑
            $this->handleException($e);

            // 返回异常响应
            $response = $app->getService('response');
