注意，这里在*路径操作函数*中只声明了一个依赖项，即 `query_or_cookie_extractor` 。

但 **FastAPI** 必须先处理 `query_extractor`，以便在调用 `query_or_cookie_extractor` 时使用 `query_extractor` 返回的结果。

///

```mermaid
graph TB

query_extractor(["query_extractor"])
query_or_cookie_extractor(["query_or_cookie_extractor"])

read_query["/items/"]

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

## 多次使用同一个依赖项

			"\t3",

	{
		"multiline macro with arguments",
		lines(
			"#define A(a, b, c) a\\",

새로운 요청이 도착할 때마다, **FastAPI**는 다음을 처리합니다:

* 올바른 매개변수를 가진 의존성("디펜더블") 함수를 호출합니다.
* 함수에서 결과를 받아옵니다.
* *경로 작동 함수*에 있는 매개변수에 그 결과를 할당합니다

```mermaid
graph TB

common_parameters(["common_parameters"])
read_items["/items/"]
read_users["/users/"]

common_parameters --> read_items
common_parameters --> read_users
```

*path operation関数*の中で宣言している依存関係は`query_or_cookie_extractor`の１つだけであることに注意してください。

しかし、**FastAPI** は`query_extractor`を最初に解決し、その結果を`query_or_cookie_extractor`を呼び出す時に渡す必要があることを知っています。

///

```mermaid
graph TB

query_extractor(["query_extractor"])
query_or_cookie_extractor(["query_or_cookie_extractor"])

read_query["/items/"]

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