Laravel 5.4:找不到类'App \ Http \ Controllers \ Response'错误 [英] Laravel 5.4: Class 'App\Http\Controllers\Response' not found error

问题描述

我正在关注Laracast的API教程，并尝试创建所有其他控制器扩展的ApiController. ApiController负责响应处理.

I am following the Laracast's API tutorial and trying to create an ApiController that all the other controllers extend. ApiController is responsible for response handling.

class ApiController extends Controller
{
    protected $statusCode;

    public function getStatusCode()
    {
        return $this->statusCode;
    }

    public function setStatusCode($statusCode)
    {
        $this->statusCode = $statusCode;
    }

    public function respondNotFound($message = 'Not Found!')
    {
        return Reponse::json([

            'error' => [
                'message' => $message,
                'status_code' => $this->getStatusCode()
            ]

        ]);
    }
}

我还有一个扩展了ApiController的ReportController.

class ReportController extends ApiController
{
    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        $report = Report::find($id);

        if (! $report ) {
            $this->respondNotFound(Report does not exist.');
        }

        return Response::json([
            'data'=> $this->ReportTransformer->transform($report)
        ], 200);
    }
}

当我尝试从ReportController调用respondNotFound方法时，我得到了

When i try to call respondNotFound method from ReportController i get

找不到类'App \ Http \ Controllers \ Response'错误

Class 'App\Http\Controllers\Response' not found error

尽管我将use Illuminate\Support\Facades\Response;添加到父类或子类中，但我得到了错误.我该如何解决?

eventhough i add use Illuminate\Support\Facades\Response;to parent or child class i get the error. How can i fix this ?

任何帮助将不胜感激.

推荐答案

由于它是外墙，请添加以下内容:

Since it's a facade, add this:

use Response;

或使用完整的名称空间:

Or use full namespace:

return \Response::json(...);

或仅使用辅助程序:

return response()->json(...);
