### Власний тип вмісту OpenAPI { #custom-openapi-content-type }

Використовуючи той самий прийом, ви можете застосувати модель Pydantic, щоб визначити Схему JSON, яка потім включається в користувацький розділ OpenAPI-схеми для *операції шляху*.

你也可以使用一般的 `def` 函式（沒有 `async`），並同樣使用 `yield`。

FastAPI 會確保正確執行，不會阻塞事件迴圈。

由於此函式不是 async，正確的回傳型別是 `Iterable[Item]`：

{* ../../docs_src/server_sent_events/tutorial001_py310.py ln[28:31] hl[29] *}

### 無回傳型別 { #no-return-type }

你也可以省略回傳型別。FastAPI 會使用 [`jsonable_encoder`](./encoder.md) 轉換資料並送出。

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

## `ServerSentEvent` { #serversentevent }
