## Before you start

Before starting to work on a feature or a bug fix, please open an issue to discuss the use case or bug with us, or post a comment in the relevant issue. 
This can save everyone a lot of time and frustration.

For any non-trivial change, we need to be able to answer these questions:

* Why is this change done? What's the use case?

戻り値の型を省略することもできます。FastAPI は [`jsonable_encoder`](./encoder.md) を使ってデータを変換し、送信します。

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[34:37] hl[35] *}

## `ServerSentEvent` { #serversentevent }

`event`、`id`、`retry`、`comment` などの SSE フィールドを設定する必要がある場合は、生データの代わりに `ServerSentEvent` オブジェクトを `yield` できます。

`ServerSentEvent` は `fastapi.sse` からインポートします:

{* ../../docs_src/server_sent_events/tutorial002_py310.py hl[4,26] *}

你也可以省略返回类型。FastAPI 将使用 [`jsonable_encoder`](./encoder.md) 转换数据并发送。

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[34:37] hl[35] *}

## `ServerSentEvent` { #serversentevent }

如果你需要设置 `event`、`id`、`retry` 或 `comment` 等 SSE 字段，你可以 yield `ServerSentEvent` 对象，而不是直接返回数据。

从 `fastapi.sse` 导入 `ServerSentEvent`：

{* ../../docs_src/server_sent_events/tutorial002_py310.py hl[4,26] *}
