* `headers` – Ein `dict` von Strings.
* `media_type` – Ein `str`, der den Medientyp angibt. Z. B. `"text/html"`.

FastAPI (eigentlich Starlette) fügt automatisch einen Content-Length-Header ein. Außerdem wird es einen Content-Type-Header einfügen, der auf dem media_type basiert, und für Texttypen einen Zeichensatz (charset) anfügen.

### `HTMLResponse`

만약 들여쓰기 및 포맷된 JSON을 반환하고 싶다면, `orjson.OPT_INDENT_2` 옵션을 사용할 수 있습니다.

`CustomORJSONResponse`를 생성할 수 있습니다. 여기서 핵심은 `Response.render(content)` 메서드를 생성하여 내용을 `bytes`로 반환하는 것입니다:

{* ../../docs_src/custom_response/tutorial009c.py hl[9:14,17] *}

이제 다음 대신:

```json
{"message": "Hello World"}
```

이 응답은 이렇게 반환됩니다:

FastAPI (actually Starlette) will automatically include a Content-Length header. It will also include a Content-Type header, based on the `media_type` and appending a charset for text types.
