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}

```

`/docs`를 확인하면 `data` 필드가 base64로 인코딩된 bytes를 기대한다고 표시됩니다:

아래와 같은 요청을 보낼 수 있습니다:

```json

/// tip | 팁

`aGVsbG8=`는 `hello`의 base64 인코딩입니다.
