/// note | "技術詳細"

`from starlette.middleware.cors import CORSMiddleware` も使用できます。

**FastAPI** は、開発者の利便性を高めるために、`fastapi.middleware` でいくつかのミドルウェアを提供します。利用可能なミドルウェアのほとんどは、Starletteから直接提供されています。

* 만약 매개변수가 **경로**에도 선언되어 있다면, 이는 경로 매개변수로 사용될 것입니다.
* 만약 매개변수가 (`int`, `float`, `str`, `bool` 등과 같은) **유일한 타입**으로 되어있으면, **쿼리** 매개변수로 해석될 것입니다.
* 만약 매개변수가 **Pydantic 모델** 타입으로 선언되어 있으면, 요청 **본문**으로 해석될 것입니다.

/// note | "참고"

FastAPI는 `q`의 값이 필요없음을 알게 될 것입니다. 기본 값이 `= None`이기 때문입니다.

`Union[str, None]`에 있는 `Union`은 FastAPI에 의해 사용된 것이 아니지만, 편집기로 하여금 더 나은 지원과 에러 탐지를 지원할 것입니다.

## Example

### Create it

* Create a file `main.py` with:

```Python
from typing import Union

    return CollectCollectors.flatteningToImmutableSetMultimap(keyFunction, valuesFunction);
  }

  /**
   * Returns the empty multimap.
   *
   * <p><b>Performance note:</b> the instance returned is a singleton.
   */
  // Casting is safe because the multimap will never hold any elements.
  @SuppressWarnings("unchecked")
  public static <K, V> ImmutableSetMultimap<K, V> of() {

   *       threads, RPC network threads, or other latency-sensitive threads. In those cases, slow
   *       listeners can harm responsiveness, slow the system as a whole, or worse. (See also the
   *       note about locking below.)
   *   <li>If many tasks will be triggered by the same event, one heavyweight task may delay other
   *       tasks -- even tasks that are not themselves {@code directExecutor} tasks.
