PHP:超薄框架异常处理

我刚刚用slim框架创建了一个API应用程序,最初,在我的代码中,我使用一个依赖容器来处理抛出的所有异常,代码如下.

//Add container to handle all exceptions/errors, fail safe and return json
$container['errorHandler'] = function ($container) {
    return function ($request, $response, $exception) use ($container) {
        //Format of exception to return
        $data = [
            'message' => $exception->getMessage()
        ];
        return $container->get('response')->withStatus(500)
            ->withHeader('Content-Type', 'application/json')
            ->write(json_encode($data));
    };
};

但是,我不想一直抛出500服务器错误,而是想添加其他HTTPS响应代码.我想知道我是否可以获得如何解决这个问题的帮助.

public static function decodeToken($token)
{
    $token = trim($token);
    //Check to ensure token is not empty or invalid
    if ($token === '' || $token === null || empty($token)) {
        throw new JWTException('Invalid Token');
    }
    //Remove Bearer if present
    $token = trim(str_replace('Bearer ', '', $token));

    //Decode token
    $token = JWT::decode($token, getenv('SECRET_KEY'), array('HS256'));

    //Ensure JIT is present
    if ($token->jit == null || $token->jit == "") {
        throw new JWTException('Invalid Token');
    }

    //Ensure User Id is present
    if ($token->data->uid == null || $token->data->uid == "") {
        throw new JWTException("Invalid Token");
    }
    return $token;
}

问题更多来自上面的函数,因为slim框架决定隐式处理所有异常,我无权使用try catch来捕获任何错误

最佳答案
不是那么难,很简单.重写代码:

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

那么这段代码有什么用呢?你基本上像以前一样传递$响应,这段代码的作用是它从$response对象获取状态代码并将其传递给withStatus()方法.

Slim Documentation for referring to status.
