response()->json() 可以省略不写？

vendor/laravel/framework/src/Illuminate/Routing/Router.php

        if ($response instanceof Responsable) {
            $response = $response->toResponse($request);
        }

        if ($response instanceof PsrResponseInterface) {
            $response = (new HttpFoundationFactory)->createResponse($response);
        } elseif ($response instanceof Model && $response->wasRecentlyCreated) {
            $response = new JsonResponse($response, 201);
        } elseif (! $response instanceof SymfonyResponse &&
                   ($response instanceof Arrayable ||
                    $response instanceof Jsonable ||
                    $response instanceof ArrayObject ||
                    $response instanceof JsonSerializable ||
                    is_array($response))) {
            $response = new JsonResponse($response);
        } elseif (! $response instanceof SymfonyResponse) {
            $response = new Response($response, 200, ['Content-Type' => 'text/html']);
        }

        if ($response->getStatusCode() === Response::HTTP_NOT_MODIFIED) {
            $response->setNotModified();
        }

        return $response->prepare($request);

如果是数组，$response = new JsonResponse($response)

So，只是单纯返回数据，不定义status、headers这些，直接return数组是可以的

楼上正解，我也一直这么写
