如何从扩展控制器获取变量？

Question

我有这个基本控制器：

abstract class ApiController extends BaseController {

use DispatchesCommands, ValidatesRequests;
public function __construct()
{
    try {
        $user = JWTAuth::parseToken()->toUser();
    } catch (Exception $e) {
        return Response::json(['error' => $e->getMessage()], HttpResponse::HTTP_UNAUTHORIZED);
    }
}
}

如何在子控制器中获取 $user 变量？如果可能，请提供示例子控制器。

Answer 1

首先：

abstract class ApiController extends BaseController {

  use DispatchesCommands, ValidatesRequests;

  protected $user; // or public
  public function __construct()
  {
    try {
        $this->user = JWTAuth::parseToken()->toUser();
    } catch (Exception $e) {
        return Response::json(['error' => $e->getMessage()], HttpResponse::HTTP_UNAUTHORIZED);
    }
  }
}

然后：

class Ctrl extends ApiController
{
  public function whatever()
  {
    echo $this->user;
  }
}
