* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* usw.

```Python hl_lines="6"
{!../../../docs_src/response_status_code/tutorial001.py!}
```

!!! note "Hinweis"

与指定响应模型的方式相同，在以下任意*路径操作*中，可以使用 `status_code` 参数声明用于响应的 HTTP 状态码：

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* 等……

```Python hl_lines="6"
{!../../../docs_src/response_status_code/tutorial001.py!}
```

!!! note "笔记"

    注意，`status_code` 是（`get`、`post` 等）**装饰器**方法中的参数。与之前的参数和请求体不同，不是*路径操作函数*的参数。

`status_code` 参数接收表示 HTTP 状态码的数字。

!!! info "说明"

* `@app.get()`
* `@app.post()`
* `@app.put()`
* `@app.delete()`
* など。

```Python hl_lines="6"
{!../../../docs_src/response_status_code/tutorial001.py!}
```

!!! note "備考"
    `status_code`は「デコレータ」メソッド（`get`、`post`など）のパラメータであることに注意してください。すべてのパラメータやボディのように、*path operation関数*のものではありません。

`status_code`パラメータはHTTPステータスコードを含む数値を受け取ります。

!!! info "情報"

You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank}.

But in some cases you need to return a different status code than the default.

## Use case

For example, imagine that you want to return an HTTP status code of "OK" `200` by default.

But if the data didn't exist, you want to create it, and return an HTTP status code of "CREATED" `201`.

# Response - Cambiar el Status Code

Probablemente ya has leído con anterioridad que puedes establecer un [Response Status Code](../tutorial/response-status-code.md){.internal-link target=_blank} por defecto.

Pero en algunos casos necesitas retornar un status code diferente al predeterminado.

## Casos de uso

Por ejemplo, imagina que quieres retornar un HTTP status code de "OK" `200` por defecto.

Anschließend können Sie den `status_code` in diesem *vorübergehenden* Response-Objekt festlegen.

```Python hl_lines="1  9  12"
{!../../../docs_src/response_change_status_code/tutorial001.py!}
```

Und dann können Sie wie gewohnt jedes benötigte Objekt zurückgeben (ein `dict`, ein Datenbankmodell usw.).
