lumen - handler.php不反映更新

Question

I modified render method of Exceptions/Handler.php to return my own response instead of rendering lumen's error page when any errors occur.

Here is my render method updated.

/**
 * Render an exception into an HTTP response.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Exception  $e
 * @return \Illuminate\Http\Response
 */
public function render($request, Exception $e)
{
    // return parent::render($request, $e);
    return response()
                ->json([
                    'errors' => $e
                ]);
}

I expected it return my response when NotFoundHttpException happens, but lumen still shows its original error page...

I understand I should modify app/Exceptions/Handler.php, but because it doesn't work as I expect, I modified vendor/laravel/lumen/app/Exceptions/Handler.php instead. Here is the updated file.

/**
 * Render an exception into an HTTP response.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  \Exception  $e
 * @return \Illuminate\Http\Response
 */
public function render($request, Exception $e)
{
    return response(['test'=> 'test']);
    // return parent::render($request, $e);
}

It works as I expected (not showing error page but return json response).

In bootstrap/app.php, it seems correctly set to call App\Exceptions\Handler::class, not laravel\lumen\app\Exceptions\Handler::class.

$app->singleton(
    Illuminate\Contracts\Debug\ExceptionHandler::class,
    App\Exceptions\Handler::class
);

I've already tried reinstalling lumen and my docker environment. And I tried to modify Handler.php just after installing lumen (that is no other modification in app), but it doesn't work.

Anyone knows my changes are not reflected??

Answer 1

I set a wrong value for bootstrap/app.php.

I set like the below.

require_once __DIR__.'/../../vendor/autoload.php';

After I modified this part like following, lumen became to able to call Handler.php method.

require_once __DIR__.'/../vendor/autoload.php';
