如何将已认证的用户绑定到控制器中的参数？

Question

I cant retrieve authenticated webmaster in controller. As you can see below, i authenticate user in constructor via $this->middleware:

class DomainController 
.....
 public function __construct()
    {
        $this->middleware('auth:webmasters');
    }
    public function requestNewName(Request $request, Webmaster $webmaster, DomainRepositoryInterface $domainRepository): array
    {
        // $webmaster->id === null here
        /** @var Webmaster $webmaster */
        $webmaster = Auth::user(); // $webmaster->id === 1, all OK
        $domainRepository->requestChangeName($webmaster, $request->input('newName', ''));
        return ['result' => true];
    }
....

I think i need to bind it somewhere, but i dont understand where or how?

P. S.

Now i have in AuthServiceProvider:

    foreach ([Webmaster::class, Admin::class] as $class) {
        $this->app->bind($class, static function($app) use ($class) {
            $authenticated = Auth::user();
            /** @noinspection GetClassUsageInspection */
            return $authenticated && get_class($authenticated) === $class ? $authenticated : null;
        });
    }
}

And call this function in boot method. I bet that laravel has something for it.

You want the webmaster to be injected into your method by laravel's dependency injection.

The way you would do this is through the Service Container, which is the guy who handles the injections. When you as for a Webmaster $webmaster, it looks for a binding with that type, since you haven't done an explicit bind, it tries to give you an instance anyways, but that's a generic one.

All you gotta do is add this code in your service provider:

$this->app->bind('App\Webmaster', function ($app) {
   return Auth::user();
});

Now laravel knows how you want Webmaster to be injected into the function.
