可以直接传递 `int` 代码， 比如 `404`。

如果记不住数字码的涵义，也可以用 `status` 的快捷常量：

```Python hl_lines="3  17"
{!../../docs_src/path_operation_configuration/tutorial001.py!}
```

状态码在响应中使用，并会被添加到 OpenAPI 概图。

/// note | "技术细节"

也可以使用 `from starlette import status` 导入状态码。

**FastAPI** 的`fastapi.status` 和 `starlette.status` 一样，只是快捷方式。实际上，`fastapi.status` 直接继承自 Starlette。

Você pode declarar retornos adicionais, com códigos de status adicionais, media types, descrições, etc.

Essas respostas adicionais serão incluídas no esquema do OpenAPI, e também aparecerão na documentação da API.

Porém para as respostas adicionais, você deve garantir que está retornando um `Response` como por exemplo o `JSONResponse` diretamente, junto com o código de status e o conteúdo.
