Nesse exemplo, as *operações de rota* sob o `router` irão usar a classe `TimedRoute` personalizada, e terão um cabeçalho extra `X-Response-Time` na resposta com o tempo que levou para gerar a resposta:

        String output = testOutput.toString();

## 같은 의존성을 여러 번 사용하기 { #using-the-same-dependency-multiple-times }

같은 *경로 처리*에 대해 의존성 중 하나가 여러 번 선언되는 경우(예: 여러 의존성이 공통 하위 의존성을 갖는 경우), **FastAPI**는 그 하위 의존성을 요청당 한 번만 호출해야 한다는 것을 알고 있습니다.

query_or_cookie_extractor(["query_or_cookie_extractor"])

read_query["/items/"]

query_extractor --> query_or_cookie_extractor --> read_query
```

## 多次使用同一個相依項 { #using-the-same-dependency-multiple-times }

如果你的某個相依項在同一個路徑操作中被宣告了多次，例如多個相依共用同一個子相依，**FastAPI** 會知道只需在每次請求中呼叫該子相依一次。

它會把回傳值儲存在一個 <dfn title="用來儲存已計算/產生之值的工具／系統，以便重複使用而不必再次計算。">「快取」</dfn> 中，並在該次請求中傳遞給所有需要它的「相依者」，而不是為同一個請求多次呼叫相同的相依項。
