## 技術細節 { #technical-details }

FastAPI 內建實作了一些 SSE 的最佳實務。

- 當 15 秒內沒有任何訊息時，傳送一次**「保活」`ping` 註解**，以避免某些代理伺服器關閉連線；此作法源自於[HTML 規範：Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes)中的建議。
- 設定 `Cache-Control: no-cache` 標頭，以**防止快取**串流內容。

Wenn Sie die `/docs` aufrufen, zeigt die Dokumentation, dass das Feld `data` base64-kodierte Bytes erwartet:

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

Sie könnten einen Request wie folgt senden:

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

/// tip | Tipp

`aGVsbG8=` ist die base64-Kodierung von `hello`.

Dokümanlarınızda normal *path operation*'ları ve artık bazı **webhook**'ları da göreceksiniz:

## Как запретить дополнительные заголовки { #forbid-extra-headers }

В некоторых случаях (не особо часто встречающихся) вам может понадобиться **ограничить** заголовки, которые вы хотите получать.
