It could even be an infinite stream, where you keep sending data.

## JSON Lines { #json-lines }

In these cases, it's common to send "**JSON Lines**", which is a format where you send one JSON object per line.

A response would have a content type of `application/jsonl` (instead of `application/json`) and the body would be something like:

```json
{"name": "Plumbus", "description": "A multi-purpose household device."}

## Base64 とファイル { #base64-vs-files }

バイナリデータのアップロードにはまず、JSON にエンコードする代わりに [Request Files](../tutorial/request-files.md) を、バイナリデータの送信には [カスタムレスポンス - FileResponse](./custom-response.md#fileresponse--fileresponse-) を使えるか検討してください。

JSON は UTF-8 でエンコードされた文字列のみを含められるため、生のバイト列は含められません。

Base64 はバイナリデータを文字列にエンコードできますが、そのために元のバイナリより多くの文字を使用する必要があり、通常は通常のファイルより非効率です。

Nesse exemplo, as *operações de rota* sob o `router` irão usar a classe `TimedRoute` personalizada, e terão um cabeçalho extra `X-Response-Time` na resposta com o tempo que levou para gerar a resposta:

... então, como `description` tem um valor padrão, se você **não retornar nada** para esse campo, ele ainda terá o **valor padrão**.

### Modelo para Dados de Resposta de Saída { #model-for-output-response-data }

Se você interagir com a documentação e verificar a resposta, mesmo que o código não tenha adicionado nada em um dos campos `description`, a resposta JSON contém o valor padrão (`null`):

`with` bloğu kullanarak, jeneratör fonksiyonu (içinde `yield` olan fonksiyon) tamamlandığında dosya benzeri nesnenin kapandığından emin oluruz. Yani response gönderimi bittikten sonra.

Bu özel örnekte o kadar da önemli değil, çünkü sahte ve bellekte (yani `io.BytesIO` ile). Ancak gerçek bir dosyada, onunla işiniz bittiğinde dosyanın kapandığından emin olmak önemlidir.

    * If you didn't use FastAPI and used Starlette directly (or another tool, like Sanic, Flask, Responder, etc) you would have to implement all the data validation and serialization yourself. So, your final application would still have the same overhead as if it was built using FastAPI. And in many cases, this data validation and serialization is the...
