## Verwendung

Jetzt können Sie Ihre Abhängigkeit mithilfe dieser Klasse deklarieren.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI** ruft die Klasse `CommonQueryParams` auf. Dadurch wird eine „Instanz“ dieser Klasse erstellt und die Instanz wird als Parameter `commons` an Ihre Funktion überreicht.

compatibility.

Starting with go1.19.txt, each API feature line must end in "#nnnnn"
giving the GitHub issue number of the proposal issue that accepted
the new API. This helps with our end-of-cycle audit of new APIs.
The same requirement applies to next/* (described below), which will
become a go1.XX.txt for XX >= 19.

The next/ directory contains the only files intended to be mutated.

## Utilizando

Agora você pode declarar sua dependência utilizando essa classe.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

O **FastAPI** chama a classe `CommonQueryParams`. Isso cria uma "instância" dessa classe e é a instância que será passada para o parâmetro `commons` na sua função.

## Anotações de Tipo vs `Depends`

## Use it { #use-it }

Now you can declare your dependency using this class.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI** calls the `CommonQueryParams` class. This creates an "instance" of that class and the instance will be passed as the parameter `commons` to your function.

En ambos casos, los datos serán convertidos, validados, documentados en el esquema de OpenAPI, etc.

## Úsalo

Ahora puedes declarar tu dependencia usando esta clase.

{* ../../docs_src/dependencies/tutorial002_an_py310.py hl[19] *}

**FastAPI** llama a la clase `CommonQueryParams`. Esto crea una "instance" de esa clase y la instance será pasada como el parámetro `commons` a tu función.

## Anotación de tipos vs `Depends`

* 기본값이 `100`이면서 `정수형`인 쿼리 매개변수 `limit`

두 가지 방식 모두, 데이터는 변환, 검증되고 OpenAPI 스키마에 문서화됩니다.

## 사용해봅시다!

이제 아래의 클래스를 이용해서 의존성을 정의할 수 있습니다.

{* ../../docs_src/dependencies/tutorial002.py hl[19] *}

**FastAPI**는 `CommonQueryParams` 클래스를 호출합니다. 이것은 해당 클래스의 "인스턴스"를 생성하고 그 인스턴스는 함수의 매개변수 `commons`로 전달됩니다.

## 타입 힌팅 vs `Depends`

위 코드에서 `CommonQueryParams`를 두 번 작성한 방식에 주목하십시오:

```Python

    assertThat(recorded.headers["Accept-Encoding"]).isNull() // No built-in gzip.
    assertThat(recorded.headers["Connection"]).isEqualTo("Upgrade, HTTP2-Settings")
    if (PlatformVersion.majorVersion < 19) {
      assertThat(recorded.headers["Content-Length"]).isEqualTo("0")
    }
    assertThat(recorded.headers["HTTP2-Settings"]).isNotNull()
    assertThat(recorded.headers["Upgrade"]).isEqualTo("h2c") // HTTP/2 over plaintext!
