FastAPI versteht das und wird in der OpenAPI-Dokumentation anzeigen, dass es keinen Responsebody gibt.

Некоторые коды статуса ответа (см. следующий раздел) указывают на то, что ответ не имеет тела.

FastAPI знает об этом и создаст документацию OpenAPI, в которой будет указано, что тело ответа отсутствует.

O parâmetro de consulta `q` é do tipo `Union[str, None]`, o que significa que é do tipo `str` mas que também pode ser `None`, e de fato, o valor padrão é `None`, então o FastAPI saberá que não é obrigatório.

/// note | "Observação"

O FastAPI saberá que o valor de `q` não é obrigatório por causa do valor padrão `= None`.
