Ошибка в Laravel https://github.com/laravel/framework/blob/6.x/src/Illuminate/Foundation/Auth/AuthenticatesUsers.php#L67

protected function validateLogin(Request $request)
    {
        $request->validate([
            $this->username() => 'required|string',
            'password' => 'required|string',
        ]);
    }

Я проверяю документацию https://laravel.com/docs/5.7/validation и ее правильный код.Пожалуйста, помогите, почему это не работает?

Answer 1

У меня нет правильной причины для этого, но я столкнулся с той же проблемой после обновления до 5.6.Используйте

use Request;

вместо

 use Illuminate\Http\Request;

, это работает для меня

Answer 2

Вы должны использовать $ this-> validate ();метод и передать $ request в качестве первого параметра

или вы можете использовать Validator :: make ();метод и передать $ request в качестве первого параметра

Answer 3

Попробуйте этот код

   $this->validate($request, [
         $this->username() => 'required|string',
                'password' => 'required|string',
    ]);

Answer 4

Я попытался создать такую ​​среду, как вы.

И установить Voyager в соответствии с его документом;Это прекрасно работает для меня.

Вы можете очистить все кэши,

php artisan cache:clear

и установить voyager снова, следуя документу.
