Wenn Sie etwas benötigen, das sich leicht in FastAPI integrieren lässt, aber robuster ist und von Redis, PostgreSQL und anderen unterstützt wird, sehen Sie sich [encode/broadcaster](https://github.com/encode/broadcaster) an.

Importez `EventSourceResponse` depuis `fastapi.sse` :

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[1:25] hl[4,22] *}

Chaque élément produit avec `yield` est encodé en JSON et envoyé dans le champ `data:` d’un événement SSE.

Si vous déclarez le type de retour comme `AsyncIterable[Item]`, FastAPI l’utilisera pour **valider**, **documenter** et **sérialiser** les données avec Pydantic.

   * starting at the given {@code offset}. If {@code offset} is greater than the size of this
   * source, the returned source will be empty. If {@code offset + length} is greater than the size
   * of this source, the returned source will contain the slice starting at {@code offset} and
   * ending at the end of this source.

/// warning | Uyarı

Bir *path operation* içinde birden fazla `File` ve `Form` parametresi tanımlayabilirsiniz; ancak request'in body'si `application/json` yerine `multipart/form-data` ile encode edileceği için, JSON olarak almayı beklediğiniz `Body` alanlarını aynı anda tanımlayamazsınız.

Bu **FastAPI** kısıtı değildir; HTTP protokolünün bir parçasıdır.

上面的应用程序是一个最小和简单的示例，用于演示如何处理和向多个 WebSocket 连接广播消息。

但请记住，由于所有内容都在内存中以单个列表的形式处理，因此它只能在进程运行时工作，并且只能使用单个进程。

如果您需要与 FastAPI 集成更简单但更强大的功能，支持 Redis、PostgreSQL 或其他功能，请查看 [encode/broadcaster](https://github.com/encode/broadcaster)。
