Question

我正在尝试处理苗条框架自定义中间件中的错误，但不知道如何在我的代码中执行此操作我正在这样做，如果请求不是四种特定类型然后通过错误，我想在错误的哈德尔inHandler有适当的消息和状态，但目前这个代码只是在postman中返回状态，在响应正文中有一个空白屏幕。我对SLIM不太熟悉。提前致谢

<?php 

require 'vendor/autoload.php';

use \Slim\App;

$c = new \Slim\Container();

$c['notAllowedHandler'] = function ($c) { 
    return function ($request, $response, $methods) use ($c) {
        return $c['response']
            ->withStatus(405)
            ->withHeader('Allow', implode(', ', $methods))
            ->withHeader('Content-type', 'application/json')
        ->write(json_encode(array("c_status"=>"405","message"=>"Bad Request")));
    };
};

$c['notFoundHandler'] = function ($c) {
    return function ($request, $response) use ($c) {
        return $c['response']
            ->withStatus(404)
            ->withHeader('Content-type', 'application/json')
        ->write(json_encode(array("c_status"=>"404","message"=>"Not Found")));
    };
};


$c['errorHandler'] = function ($c) {
    return function ($request, $response, $exception) use ($c) {
        $data = [
            'c_status' => $response->getStatus(),
            'message' => $exception->getMessage()
        ];
        return $container->get('response')->withStatus($response->getStatus())
            ->withHeader('Content-Type', 'application/json')
            ->write(json_encode($data));
    };
};

$app = new App($c);

$app->add(function ($request, $response, $next) {
    if($request->isGet() || $request->isPost() || $request->isPut() || $request->isDelete()){
        $response = $next($request, $response);
    }else{
        $response = $response->withStatus(403);
    }
    return $response;
});

require 'API/routes.php';
$app->run();

Answer 1

抛出异常：

$app->add(function ($request, $response, $next) {
    if($request->isGet() || $request->isPost() || $request->isPut() || $request->isDelete()){
        $response = $next($request, $response);
    }else{
        throw new \Exception("Forbidden", 403);
    }
    return $response;
})
