# 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`。

	if existing == nil {
		existing = &k8sv1.GatewayClassStatus{}
	}
	existing.Conditions = kstatus.UpdateConditionIfChanged(existing.Conditions, metav1.Condition{
		Type:               string(k8sv1.GatewayClassConditionStatusAccepted),
		Status:             kstatus.StatusTrue,
		ObservedGeneration: gen,
		LastTransitionTime: metav1.Now(),
