Если вы откроете `/docs`, вы увидите, что поле `data` ожидает байты, закодированные в base64:

<div class="screenshot">
<img src="/img/tutorial/json-base64-bytes/image01.png">
</div>

Вы можете отправить такой HTTP-запрос:

```json
{
    "description": "Some data",
    "data": "aGVsbG8="
}
```

/// tip | Совет

`aGVsbG8=` — это base64-кодирование строки `hello`.

SSE ist ein Standard zum Streamen von Daten vom Server zum Client über HTTP.

Jedes Event ist ein kleiner Textblock mit „Feldern“ wie `data`, `event`, `id` und `retry`, getrennt durch Leerzeilen.

Das sieht so aus:

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```

SSE é um padrão para transmitir dados do servidor para o cliente via HTTP.

Cada evento é um pequeno bloco de texto com “campos” como `data`, `event`, `id` e `retry`, separados por linhas em branco.

Fica assim:

```
data: {"name": "Portal Gun", "price": 999.99}

data: {"name": "Plumbus", "price": 32.99}

```
