# Status Codes

You can import the `status` module from `fastapi`:

```python
from fastapi import status
```

`status` is provided directly by Starlette.

It contains a group of named constants (variables) with integer status codes.

For example:

* 200: `status.HTTP_200_OK`
* 403: `status.HTTP_403_FORBIDDEN`
* etc.

/// note

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

## About HTTP status codes { #about-http-status-codes }

/// note

If you already know what HTTP status codes are, skip to the next section.

Puedes usar las variables de conveniencia de `fastapi.status`.

{* ../../docs_src/response_status_code/tutorial002_py39.py hl[1,6] *}

Son solo una conveniencia, mantienen el mismo número, pero de esa manera puedes usar el autocompletado del editor para encontrarlos:

/// note | Detalles técnicos

También podrías usar `from starlette import status`.

# Códigos de status adicionais { #additional-status-codes }

Por padrão, o **FastAPI** retornará as respostas utilizando o `JSONResponse`, adicionando o conteúdo do retorno da sua *operação de rota* dentro do `JSONResponse`.

Ele usará o código de status padrão ou o que você definir na sua *operação de rota*.

## Códigos de status adicionais { #additional-status-codes_1 }

Ви можете використовувати зручні змінні з `fastapi.status`

{* ../../docs_src/response_status_code/tutorial002.py hl[1,6] *}

Ці змінні просто для зручності. Вони містять ті ж самі числа, але Ви можете скористатися автозаповненням в редакторі:

<img src="/img/tutorial/response-status-code/image02.png">

/// note | Технічні деталі

Ви також можете використати `from starlette import status`.

这只是一种快捷方式，具有相同的数字代码，但它可以使用编辑器的自动补全功能：

<img src="../../../../../../img/tutorial/response-status-code/image02.png">

/// note | 技术细节

也可以使用 `from starlette import status`。

为了让开发者更方便，**FastAPI** 提供了与 `starlette.status` 完全相同的 `fastapi.status`。但它直接来自于 Starlette。

///

## 更改默认状态码

/// note | 기술적 세부사항

`from starlette import status` 역시 사용할 수 있습니다.

**FastAPI**는 개발자인 여러분의 편의를 위해 `fastapi.status` 와 동일한 `starlette.status` 도 제공합니다. 하지만 이것은 Starlette로부터 직접 제공됩니다.

///

## 기본값 변경

# Additional Status Codes { #additional-status-codes }

By default, **FastAPI** will return the responses using a `JSONResponse`, putting the content you return from your *path operation* inside of that `JSONResponse`.

It will use the default status code or the one you set in your *path operation*.

## Additional status codes { #additional-status-codes_1 }
