    {
        $headers = [
            'Content-type' => 'application/json;charset=UTF-8',
            'Access-Control-Allow-Origin' => '*',

        if ($request->isMethod('OPTIONS')) {
            return response()->json('{"method":"OPTIONS"}', 200, $headers);
        }
        $response = $next($request);
        foreach ($headers as $key => $value) {
            $response->headers->set($key, $value);
        }
        return $response;
