また、`from starlette import status`を使うこともできます。

**FastAPI** は、開発者の利便性を考慮して、fastapi.statusと同じ`starlette.status`を提供しています。しかし、これはStarletteから直接提供されています。

To know more about each status code and which code is for what, check the [<abbr title="Mozilla Developer Network">MDN</abbr> documentation about HTTP status codes](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status).

# Código de status de resposta { #response-status-code }

Da mesma forma que você pode especificar um modelo de resposta, você também pode declarar o código de status HTTP usado para a resposta com o parâmetro `status_code` em qualquer uma das *operações de rota*:

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

/// note | Nota

# Use Old 403 Authentication Error Status Codes { #use-old-403-authentication-error-status-codes }

Before FastAPI version `0.122.0`, when the integrated security utilities returned an error to the client after a failed authentication, they used the HTTP status code `403 Forbidden`.

它們只是方便用的常數，值與數字相同，但這樣你可以用編輯器的自動完成來找到它們：

/// note | 技術細節

你也可以使用 `from starlette import status`。

**FastAPI** 將同一個 `starlette.status` 以 `fastapi.status` 形式提供，純粹是為了讓你（開發者）方便。但它直接來自 Starlette。

/// note | Remarque

Certains codes de réponse (voir la section suivante) indiquent que la réponse n'a pas de corps.

FastAPI le sait et produira une documentation OpenAPI indiquant qu'il n'y a pas de corps de réponse.

Einige Responsecodes (siehe nächsten Abschnitt) kennzeichnen, dass die Response keinen Body hat.

FastAPI erkennt dies und erstellt eine OpenAPI-Dokumentation, die zeigt, dass es keinen Responsebody gibt.

Некоторые коды статуса ответа (см. следующий раздел) указывают на то, что ответ не имеет тела.

FastAPI знает об этом и создаст документацию OpenAPI, в которой будет указано, что тело ответа отсутствует.

You probably read before that you can set a default [Response Status Code](../tutorial/response-status-code.md).

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

## Use case { #use-case }

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