Disons que vous voulez renvoyer du JSON indenté et formaté, donc vous voulez utiliser l'option orjson `orjson.OPT_INDENT_2`.

Vous pourriez créer une `CustomORJSONResponse`. L'essentiel est de créer une méthode `Response.render(content)` qui renvoie le contenu en `bytes` :

{* ../../docs_src/custom_response/tutorial009c_py310.py hl[9:14,17] *}

Maintenant, au lieu de renvoyer :

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

### SDK'yı Kullanma { #using-the-sdk }

Artık client code'u import edip kullanabilirsiniz. Şuna benzer görünebilir; method'lar için otomatik tamamlama aldığınıza dikkat edin:

<img src="/img/tutorial/generate-clients/image02.png">

Ayrıca gönderilecek payload için de otomatik tamamlama alırsınız:

// The Header.Size determines how many bytes can be written for the next file.
// If the current file is not fully written, then this returns an error.
// This implicitly flushes any padding necessary before writing the header.
func (tw *Writer) WriteHeader(hdr *Header) error {
	if err := tw.Flush(); err != nil {
		return err
	}
	tw.hdr = *hdr // Shallow copy of Header

class APIKeyHeader(APIKeyBase):

    API key authentication using a header.

    This defines the name of the header that should be provided in the request with
    the API key and integrates that into the OpenAPI documentation. It extracts
    the key value sent in the header automatically and provides it as the dependency
    result. But it doesn't define how to send that key to the client.

* `headers` - Un `dict` de strings.
* `media_type` - Un `str` que da el media type. Por ejemplo, `"text/html"`.

FastAPI (de hecho Starlette) incluirá automáticamente un header Content-Length. También incluirá un header Content-Type, basado en el `media_type` y añadiendo un conjunto de caracteres para tipos de texto.
