# Path Operationの設定

*path operationデコレータ*を設定するためのパラメータがいくつかあります。

/// warning | 注意

これらのパラメータは*path operation関数*ではなく、*path operationデコレータ*に直接渡されることに注意してください。

///

## レスポンスステータスコード

*path operation*のレスポンスで使用する（HTTP）`status_code`を定義することができます。

`404`のように`int`のコードを直接渡すことができます。

しかし、それぞれの番号コードが何のためのものか覚えていない場合は、`status`のショートカット定数を使用することができます:

{* ../../docs_src/path_operation_configuration/tutorial001.py hl[3,17] *}

# Configuración de Path Operation { #path-operation-configuration }

Hay varios parámetros que puedes pasar a tu *path operation decorator* para configurarlo.

/// warning | Advertencia

Ten en cuenta que estos parámetros se pasan directamente al *path operation decorator*, no a tu *path operation function*.

///

## Código de Estado del Response { #response-status-code }

Então, se você não fornecer uma, o **FastAPI** irá gerar automaticamente uma de "Resposta bem-sucedida".

///

<img src="/img/tutorial/path-operation-configuration/image03.png">

## Descontinuar uma *operação de rota* { #deprecate-a-path-operation }

Se você precisar marcar uma *operação de rota* como <abbr title="obsoleta, recomendada não usá-la">descontinuada</abbr>, mas sem removê-la, passe o parâmetro `deprecated`:

如果没有定义响应描述，**FastAPI** 则自动生成内容为 "Successful response" 的响应描述。

///

<img src="/img/tutorial/path-operation-configuration/image03.png">

## 弃用*路径操作*

`deprecated` 参数可以把*路径操作*标记为<abbr title="过时，建议不要使用">弃用</abbr>，无需直接删除：

{* ../../docs_src/path_operation_configuration/tutorial006.py hl[16] *}

API 文档会把该路径操作标记为弃用：

<img src="/img/tutorial/path-operation-configuration/image04.png">

下图显示了正常*路径操作*与弃用*路径操作* 的区别：

///

<img src="/img/tutorial/path-operation-configuration/image03.png">

## 단일 *경로 작동* 지원중단

단일 *경로 작동*을 없애지 않고 <abbr title="구식, 사용하지 않는것이 권장됨">지원중단</abbr>을 해야한다면, `deprecated` 매개변수를 전달하면 됩니다.

{* ../../docs_src/path_operation_configuration/tutorial006.py hl[16] *}

대화형 문서에 지원중단이라고 표시됩니다.

# Path Operation Configuration { #path-operation-configuration }

There are several parameters that you can pass to your *path operation decorator* to configure it.

/// warning

Notice that these parameters are passed directly to the *path operation decorator*, not to your *path operation function*.

///

## Response Status Code { #response-status-code }

You can define the (HTTP) `status_code` to be used in the response of your *path operation*.
