Laravel 5.4: Class 'App\Http\Controllers\Response' not found error
提问by Tartar
I am following the Laracast's API tutorial and trying to create an ApiControllerthat all the other controllers extend. ApiControlleris responsible for response handling.
我正在关注 Laracast 的 API 教程并尝试创建一个ApiController所有其他控制器都扩展的。ApiController负责响应处理。
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()
]
]);
}
}
And i also have a ReportControllerthat extends ApiController.
我也有一个ReportController扩展ApiController。
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);
}
}
When i try to call respondNotFoundmethod from ReportControlleri get
当我尝试respondNotFound从ReportController我那里调用方法时
Class 'App\Http\Controllers\Response' not found error
找不到类“App\Http\Controllers\Response”错误
eventhough i add use Illuminate\Support\Facades\Response;to parent or child class i get the error. How can i fix this ?
尽管我添加use Illuminate\Support\Facades\Response;到父类或子类，但我收到错误。我怎样才能解决这个问题 ？
Any help would be appreciated.
任何帮助，将不胜感激。

Since it's a facade, add this:
因为它是一个门面，添加这个：
use Response;
Or use full namespace:
或者使用完整的命名空间：
return \Response::json(...);
Or just use helper:
或者只是使用助手：
return response()->json(...);
