## Recap { #recap }

You can add multiple body parameters to your *path operation function*, even though a request can only have a single body.

But **FastAPI** will handle it, give you the correct data in your function, and validate and document the correct schema in the *path operation*.

You can also declare singular values to be received as part of the body.

    return count(object) > 0;

## 使用 FastAPI 串流 SSE { #stream-sse-with-fastapi }

要在 FastAPI 中串流 SSE，請在你的路徑操作函式（path operation function）中使用 `yield`，並設定 `response_class=EventSourceResponse`。

從 `fastapi.sse` 匯入 `EventSourceResponse`：

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

このセクションではその方法を説明します。

## 通常のプロセス { #the-normal-process }

通常（デフォルト）のプロセスは次のとおりです。

`FastAPI` アプリケーション（インスタンス）には、OpenAPI スキーマを返すことが期待される `.openapi()` メソッドがあります。

アプリケーションオブジェクトの作成時に、`/openapi.json`（または `openapi_url` に設定したパス）への path operation が登録されます。

これは単に、アプリケーションの `.openapi()` メソッドの結果を含む JSON レスポンスを返します。

デフォルトでは、`.openapi()` メソッドはプロパティ `.openapi_schema` に内容があるかを確認し、あればそれを返します。

なければ、`fastapi.openapi.utils.get_openapi` にあるユーティリティ関数を使って生成します。
