Здесь мы используем `Query()`, потому что это **query-параметр**. Позже мы увидим другие — `Path()`, `Body()`, `Header()` и `Cookie()`, — они также принимают те же аргументы, что и `Query()`.

///

Теперь FastAPI будет:

* **валидировать** данные, удостоверяясь, что максимальная длина — 50 символов;

		return
	}

	// Ensure body content type is opaque to ensure that request body has not
	// been interpreted as form data.
	contentType := r.Header.Get("Content-Type")
	if contentType != "application/octet-stream" {
		writeErrorResponseJSON(ctx, w, errorCodes.ToAPIErr(ErrBadRequest), r.URL)
		return
	}

	// Validate operation

**Spoiler-Alarm**: Das Tutorial – Benutzerhandbuch enthält:

* Deklaration von **Parametern** von anderen verschiedenen Stellen wie: **Header**, **Cookies**, **Formularfelder** und **Dateien**.
* Wie man **Validierungs-Constraints** wie `maximum_length` oder `regex` setzt.

/// tip | Tipp

Hier verwenden wir `Query()`, weil dies ein **Query-Parameter** ist. Später werden wir andere wie `Path()`, `Body()`, `Header()`, und `Cookie()` sehen, die auch dieselben Argumente wie `Query()` akzeptieren.

///

FastAPI wird nun:

* Die Daten **validieren**, um sicherzustellen, dass die Länge maximal 50 Zeichen beträgt

/// tip | Dica

Aqui estamos usando `Query()` porque este é um parâmetro de consulta. Mais adiante veremos outros como `Path()`, `Body()`, `Header()` e `Cookie()`, que também aceitam os mesmos argumentos que `Query()`.

///

Agora o FastAPI vai:

* Validar os dados garantindo que o comprimento máximo seja de 50 caracteres

/// tip | İpucu

Örneği basit tutmak için uydurma bir header kullanıyoruz.

Ancak gerçek senaryolarda, entegre [Security yardımcı araçlarını](security/index.md) kullanarak daha iyi sonuç alırsınız.
