For those cases, you can use a `Response` parameter.

## Use a `Response` parameter { #use-a-response-parameter }

You can declare a parameter of type `Response` in your *path operation function* (as you can do for cookies and headers).

And then you can set the `status_code` in that *temporal* response object.

# `Response` class

You can declare a parameter in a *path operation function* or dependency to be of type `Response` and then you can set data for the response like headers or cookies.

You can also use it directly to create an instance of it and return it from your *path operations*.

Read more about it in the [FastAPI docs about returning a custom Response](https://fastapi.tiangolo.com/advanced/response-directly/#returning-a-custom-response)

# 自訂回應——HTML、串流、檔案與其他 { #custom-response-html-stream-file-others }

預設情況下，**FastAPI** 會回傳 JSON 回應。

你可以像在[直接回傳 Response](response-directly.md)中所示，直接回傳一個 `Response` 來覆寫它。

但如果你直接回傳一個 `Response`（或其子類別，例如 `JSONResponse`），資料將不會被自動轉換（即使你宣告了 `response_model`），而且文件也不會自動產生（例如，在產生的 OpenAPI 中包含 HTTP 標頭 `Content-Type` 的特定「media type」）。

你也可以在「路徑操作裝飾器」中使用 `response_class` 參數，宣告要使用的 `Response`（例如任意 `Response` 子類別）。

你從「路徑操作函式」回傳的內容，會被放進該 `Response` 中。

/// note

	w.WriteHeader(statusCode)
	if response != nil {
		w.Write(response)
	}
}

// mimeType represents various MIME type used API responses.
type mimeType string

const (
	// Means no response type.
	mimeNone mimeType = ""
	// Means response type is JSON.
	mimeJSON mimeType = "application/json"
	// Means response type is XML.

# Custom Response - HTML, Stream, File, others { #custom-response-html-stream-file-others }

By default, **FastAPI** will return JSON responses.

You can override it by returning a `Response` directly as seen in [Return a Response directly](response-directly.md).

# Headers de Response { #response-headers }

## Usa un parámetro `Response` { #use-a-response-parameter }

Puedes declarar un parámetro de tipo `Response` en tu *path operation function* (como puedes hacer para cookies).

Y luego puedes establecer headers en ese objeto de response *temporal*.

{* ../../docs_src/response_headers/tutorial002_py310.py hl[1, 7:8] *}

///

## Повернення `Response` { #return-a-response }

Ви можете повертати `Response` або будь-який його підклас.

/// info | Інформація

`JSONResponse` сам є підкласом `Response`.

///

І коли ви повертаєте `Response`, **FastAPI** передасть його безпосередньо.
