Это всё не важно. **FastAPI** знает, что нужно сделать. 😎

Если вам эта тема не знакома, прочтите [Async: *"In a hurry?"*](../../async.md){.internal-link target=_blank} раздел о `async` и `await` в документации.

## Интеграция с OpenAPI

Все заявления о запросах, валидаторы, требования ваших зависимостей (и подзависимостей) будут интегрированы в соответствующую OpenAPI-схему.

@app.get("/items/{item_id}")
def read_item(item_id: int, q: str = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">
<summary>または<code>async def</code>を使います...</summary>

`async` / `await`を使用するときは、 `async def`を使います:

```Python hl_lines="7 12"
from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():
    return {"Hello": "World"}

It doesn't matter. **FastAPI** will know what to do.

<summary>또는 <code>async def</code> 사용하기...</summary>

여러분의 코드가 `async` / `await`을 사용한다면, `async def`를 사용하십시오.

```Python hl_lines="9 14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():

                } finally {
                    latch.countDown();
                }
            }, "ProcessCloser-output-" + sessionId).start();

            try {
                latch.await(10, TimeUnit.SECONDS);
            } catch (final InterruptedException e) {

## Integración con OpenAPI

Todas las declaraciones de request, validaciones y requisitos de tus dependencias (y sub-dependencias) se integrarán en el mismo esquema de OpenAPI.

def read_item(item_id: int, q: Union[str, None] = None):
    return {"item_id": item_id, "q": q}
```

<details markdown="1">
<summary>Ya da <code>async def</code>...</summary>

Eğer kodunuzda `async` / `await` varsa, `async def` kullanalım:

```Python hl_lines="9  14"
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
async def read_root():

아무 문제 없습니다. **FastAPI**는 무엇을 할지 알고 있습니다.

/// note | 참고

잘 모르시겠다면, [Async: *"In a hurry?"*](../../async.md){.internal-link target=_blank} 문서에서 `async`와 `await`에 대해 확인할 수 있습니다.

## OpenAPI와 통합

모든 요청 선언, 검증과 의존성(및 하위 의존성)에 대한 요구 사항은 동일한 OpenAPI 스키마에 통합됩니다.

따라서 대화형 문서에 이러한 의존성에 대한 모든 정보 역시 포함하고 있습니다:
