# レスポンスを直接返す

**FastAPI** の *path operation* では、通常は任意のデータを返すことができます: 例えば、 `dict`、`list`、Pydanticモデル、データベースモデルなどです。

デフォルトでは、**FastAPI** は [JSON互換エンコーダ](../tutorial/encoder.md){.internal-link target=_blank} で説明されている `jsonable_encoder` により、返す値を自動的にJSONに変換します。

このとき背後では、JSON互換なデータ (例えば`dict`) を、クライアントへ送信されるレスポンスとして利用される `JSONResponse` の中に含めます。

しかし、*path operation* から `JSONResponse` を直接返すこともできます。

これは例えば、カスタムヘッダーやcookieを返すときに便利です。

## `Response` を返す

	b, err := json.Marshal(c)
	return string(b[:]), err
}

func (c *Content) Scan(src interface{}) error {
	var value Content
	str, ok := src.(string)
	if !ok {
		byt, ok := src.([]byte)
		if !ok {
			return errors.New("Embedded.Scan byte assertion failed")
		}
		if err := json.Unmarshal(byt, &value); err != nil {
			return err
		}
	} else {

But for the generated client, we could **modify** the OpenAPI operation IDs right before generating the clients, just to make those method names nicer and **cleaner**.

We could download the OpenAPI JSON to a file `openapi.json` and then we could **remove that prefixed tag** with a script like this:
