예를 들어, 사용자 정의 헤더나 쿠키를 반환해야 하는 경우에 유용할 수 있습니다.

## `Response` 반환하기

사실, `Response` 또는 그 하위 클래스를 반환할 수 있습니다.

/// tip

`JSONResponse` 자체도 `Response`의 하위 클래스입니다.

///

그리고 `Response`를 반환하면 **FastAPI**가 이를 그대로 전달합니다.

Pydantic 모델로 데이터 변환을 수행하지 않으며, 내용을 다른 형식으로 변환하지 않습니다.

이로 인해 많은 유연성을 얻을 수 있습니다. 어떤 데이터 유형이든 반환할 수 있고, 데이터 선언이나 유효성 검사를 재정의할 수 있습니다.

## `Response`에서 `jsonable_encoder` 사용하기

🔢, **FastAPI** 🔜 📨 📨 ⚙️ `JSONResponse`.

👆 💪 🔐 ⚫️ 🛬 `Response` 🔗 👀 [📨 📨 🔗](response-directly.md){.internal-link target=_blank}.

✋️ 🚥 👆 📨 `Response` 🔗, 📊 🏆 🚫 🔁 🗜, & 🧾 🏆 🚫 🔁 🏗 (🖼, 🔌 🎯 "📻 🆎", 🇺🇸🔍 🎚 `Content-Type` 🍕 🏗 🗄).

✋️ 👆 💪 📣 `Response` 👈 👆 💚 ⚙️, *➡ 🛠️ 👨‍🎨*.

🎚 👈 👆 📨 ⚪️➡️ 👆 *➡ 🛠️ 🔢* 🔜 🚮 🔘 👈 `Response`.

デフォルトでは、**FastAPI** は `JSONResponse` を使ってレスポンスを返します。

[レスポンスを直接返す](response-directly.md){.internal-link target=_blank}で見たように、 `Response` を直接返すことでこの挙動をオーバーライドできます。

しかし、`Response` を直接返すと、データは自動的に変換されず、ドキュメントも自動生成されません (例えば、生成されるOpenAPIの一部としてHTTPヘッダー `Content-Type` に特定の「メディアタイプ」を含めるなど) 。

しかし、*path operationデコレータ* に、使いたい `Response` を宣言することもできます。

*path operation関数* から返されるコンテンツは、その `Response` に含まれます。

///

It will:

* Return that status code in the response.
* Document it as such in the OpenAPI schema (and so, in the user interfaces):

<img src="/img/tutorial/response-status-code/image01.png">

/// note

Some response codes (see the next section) indicate that the response does not have a body.

FastAPI knows this, and will produce OpenAPI docs that state there is no response body.

///

## About HTTP status codes

	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.

Und Tools werden auch glücklich sein, weil sowohl `RedirectResponse` als auch `JSONResponse` Unterklassen von `Response` sind, die Typannotation ist daher korrekt.

### Eine Unterklasse von Response annotieren

Sie können auch eine Unterklasse von `Response` in der Typannotation verwenden.

```Python hl_lines="8-9"

package jcifs.smb1.util.transport;

public abstract class Response {
    public long expiration;
    public boolean isReceived;

And tools will also be happy because both `RedirectResponse` and `JSONResponse` are subclasses of `Response`, so the type annotation is correct.

### Annotate a Response Subclass

You can also use a subclass of `Response` in the type annotation:

```Python hl_lines="8-9"
{!> ../../docs_src/response_model/tutorial003_03.py!}
```

 * Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
 */
package jcifs.util.transport;


/**
 *
 */
public interface Response extends Message {

    /**
     * 
     * @return whether the response is received
     */
    boolean isReceived ();


    /**
     * Set received status
     */
    void received ();


    /**
     * Unset received status

### More info

/// note | "Technical Details"

You could also use `from starlette.responses import Response` or `from starlette.responses import JSONResponse`.

**FastAPI** provides the same `starlette.responses` as `fastapi.responses` just as a convenience for you, the developer. But most of the available responses come directly from Starlette.
