FastAPI가 이벤트 루프를 막지 않도록 올바르게 실행되게 보장합니다.

이 경우 함수가 async가 아니므로, 올바른 반환 타입은 `Iterable[Item]`입니다:

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[27:30] hl[28] *}

### 반환 타입 생략 { #no-return-type }

반환 타입을 생략할 수도 있습니다. 그러면 FastAPI가 [`jsonable_encoder`](./encoder.md)를 사용해 데이터를 JSON으로 직렬화 가능한 형태로 변환한 뒤 JSON Lines로 전송합니다.

As in this case the function is not async, the right return type would be `Iterable[Item]`:

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[27:30] hl[28] *}

### No Return Type { #no-return-type }

```Python
q: str | None = None
```

For example:

{* ../../docs_src/body_multiple_params/tutorial004_an_py310.py hl[28] *}


/// info

`Body` also has all the same extra validation and metadata parameters as `Query`, `Path` and others you will see later.

///

If you have this specific use case using SQLModel (or SQLAlchemy), you could explicitly close the session after you don't need it anymore:

{* ../../docs_src/dependencies/tutorial014_an_py310.py ln[24:28] hl[28] *}

That way the session would release the database connection, so other requests could use it.

你也可以使用常规的 `def` 函数（不带 `async`），并以同样的方式使用 `yield`。

FastAPI 会确保其正确运行，不会阻塞事件循环。

因为这个函数不是异步的，合适的返回类型是 `Iterable[Item]`：

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[27:30] hl[28] *}

### 无返回类型 { #no-return-type }

你也可以省略返回类型。此时 FastAPI 会使用 [`jsonable_encoder`](./encoder.md) 将数据转换为可序列化为 JSON 的形式，然后以 JSON Lines 发送。

{* ../../docs_src/stream_json_lines/tutorial001_py310.py ln[33:36] hl[34] *}
