# 响应 - 更改状态码

你可能之前已经了解到，你可以设置默认的[响应状态码](../tutorial/response-status-code.md){.internal-link target=_blank}。

但在某些情况下，你需要返回一个不同于默认值的状态码。

## 使用场景

例如，假设你想默认返回一个HTTP状态码为“OK”`200`。

但如果数据不存在，你想创建它，并返回一个HTTP状态码为“CREATED”`201`。

但你仍然希望能够使用`response_model`过滤和转换你返回的数据。

对于这些情况，你可以使用一个`Response`参数。

## 使用 `Response` 参数

你可以在你的*路径操作函数*中声明一个`Response`类型的参数（就像你可以为cookies和头部做的那样）。

然后你可以在这个*临时*响应对象中设置`status_code`。

		Code:           "XMinioAdminRemoteIdenticalToSource",
		Description:    "The remote target cannot be identical to source",
		HTTPStatusCode: http.StatusBadRequest,
	},
	ErrBucketRemoteAlreadyExists: {
		Code:           "XMinioAdminBucketRemoteAlreadyExists",
		Description:    "The remote target already exists",
		HTTPStatusCode: http.StatusBadRequest,
	},
	ErrBucketRemoteLabelInUse: {

Si vous avez une version plus ancienne, vous obtiendrez des erreurs en essayant d'utiliser `Annotated`.

Assurez-vous de [Mettre à jour la version de FastAPI](../deployment/versions.md#upgrading-the-fastapi-versions){.internal-link target=_blank} à la version 0.95.1 à minima avant d'utiliser `Annotated`.

[`Workload`](../../pkg/workloadapi/workload.proto) and [`Authorization`](../../pkg/workloadapi/security/authorization.proto). As such, ztunnel does not receive `PeerAuthentication`s directly; when istiod detects a `PeerAuthentication` resource that targets an Ambient captured workload, it computes the effective policy for that workload (taking into account the mesh-wide -> namespace -> workload precedence rules) and sends that policy to ztunnel. The exact details of this conversion is out of scope for...

Если вы используете более старую версию, вы столкнётесь с ошибками при попытке использовать `Annotated`.

Убедитесь, что вы [обновили версию FastAPI](../deployment/versions.md#fastapi_2){.internal-link target=_blank} как минимум до 0.95.1 перед тем, как использовать `Annotated`.
