Da mesma forma, você pode ter algumas dependências com `yield` e outras com `return` e ter uma relação de dependência entre algumas das duas.

E você poderia ter uma única dependência que precisa de diversas outras dependências com `yield`, etc.

Você pode ter qualquer combinação de dependências que você quiser.

O **FastAPI** se encarrega de executá-las na ordem certa.

## 별칭 매개변수

매개변수가 `item-query`이길 원한다고 가정해 봅시다.

마치 다음과 같습니다:

```
http://127.0.0.1:8000/items/?item-query=foobaritems
```

그러나 `item-query`은 유효한 파이썬 변수 이름이 아닙니다.

가장 가까운 것은 `item_query`일 겁니다.

하지만 정확히`item-query`이길 원합니다...

이럴 경우 `alias`를 선언할 수 있으며, 해당 별칭은 매개변수 값을 찾는 데 사용됩니다:

				for obj := range walkCh {
					if obj.Item.DeleteMarker || !obj.Item.VersionPurgeStatus.Empty() || obj.Item.Size >= int64(smallerThan) {
						slowCh <- obj
						continue
					}

					batch = append(batch, obj.Item)

					if len(batch) < *r.Source.Snowball.Batch {
						continue
					}
					writeFn(batch)
