# Alte 403-Authentifizierungsfehler-Statuscodes verwenden { #use-old-403-authentication-error-status-codes }

Vor FastAPI-Version `0.122.0` verwendeten die integrierten Sicherheits-Utilities den HTTP-Statuscode `403 Forbidden`, wenn sie dem Client nach einer fehlgeschlagenen Authentifizierung einen Fehler zurückgaben.

# Réponse - Modifier le code d'état { #response-change-status-code }

Vous avez probablement déjà lu que vous pouvez définir un [Code d'état de la réponse](../tutorial/response-status-code.md) par défaut.

Mais dans certains cas, vous devez renvoyer un code d'état différent de celui par défaut.

## Cas d'utilisation { #use-case }

Par exemple, imaginez que vous vouliez renvoyer par défaut un code d'état HTTP « OK » `200`.

# Utiliser les anciens codes d'erreur d'authentification 403 { #use-old-403-authentication-error-status-codes }

Avant FastAPI version `0.122.0`, lorsque les utilitaires de sécurité intégrés renvoyaient une erreur au client après un échec d'authentification, ils utilisaient le code d'état HTTP `403 Forbidden`.

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.

# Retorno - Altere o Código de Status { #response-change-status-code }

Você provavelmente leu anteriormente que você pode definir um [Código de Status do Retorno](../tutorial/response-status-code.md) padrão.

Porém em alguns casos você precisa retornar um código de status diferente do padrão.

## Caso de uso { #use-case }

Por exemplo, imagine que você deseja retornar um código de status HTTP de "OK" `200` por padrão.

# 回應 - 變更狀態碼 { #response-change-status-code }

你可能已經讀過，可以設定預設的[回應狀態碼](../tutorial/response-status-code.md)。

但有些情況你需要回傳與預設不同的狀態碼。

## 使用情境 { #use-case }

例如，假設你預設想回傳 HTTP 狀態碼 "OK" `200`。

但如果資料不存在，你想要建立它，並回傳 HTTP 狀態碼 "CREATED" `201`。

同時你仍希望能用 `response_model` 過濾並轉換所回傳的資料。

在這些情況下，你可以使用 `Response` 參數。

## 使用 `Response` 參數 { #use-a-response-parameter }

So, in our example, we can make `tags` be specifically a "list of strings":

{* ../../docs_src/body_nested_models/tutorial002_py310.py hl[12] *}

## Set types { #set-types }

But then we think about it, and realize that tags shouldn't repeat, they would probably be unique strings.

And Python has a special data type for sets of unique items, the `set`.

Then we can declare `tags` as a set of strings:

    assertUnescaped(e, '(');
    assertUnescaped(e, ')');
    assertUnescaped(e, '~');
    assertUnescaped(e, ':');
    assertUnescaped(e, '@');

    // Don't use plus for spaces
    assertEscaping(e, "%20", ' ');

    assertThat(e.escape("safe with spaces")).isEqualTo("safe%20with%20spaces");
    assertThat(e.escape("******@****.***")).isEqualTo("******@****.***");
  }
