### 加入回呼 router { #add-the-callback-router }

此時你已經在先前建立的回呼 router 中，擁有所需的回呼「路徑操作（們）」（也就是「外部開發者」應該在「外部 API」中實作的那些）。

現在在「你的 API 的路徑操作裝飾器」中使用參數 `callbacks`，將該回呼 router 的屬性 `.routes`（實際上就是一個由路由／「路徑操作」所組成的 `list`）傳入：

{* ../../docs_src/openapi_callbacks/tutorial001_py310.py hl[33] *}

/// tip

* path operation: operação de rota
* path operation function: função de operação de rota
* prefix: prefixo
* request (as in HTTP request): request (do not change if it's already translated to requisição)
* router (as in FastAPI's router): router (do not change if it's already translated to "roteador" or "roteadores")
* response (as in HTTP response): response (do not change if it's already translated to resposta)
* shutdown (of the app): encerramento

### 避免名称冲突 { #avoid-name-collisions }

我们将直接导入 `items` 子模块，而不是仅导入其 `router` 变量。

这是因为我们在 `users` 子模块中也有另一个名为 `router` 的变量。

如果我们一个接一个地导入，例如：

```Python
from .routers.items import router
from .routers.users import router
```

来自 `users` 的 `router` 将覆盖来自 `items` 中的 `router`，我们将无法同时使用它们。

因此，为了能够在同一个文件中使用它们，我们直接导入子模块：

from fastapi import APIRouter, Body

router = APIRouter()


@router.post("/compute/")
def compute(a: int = Body(), b: str = Body()):

{* ../../docs_src/custom_request_and_route/tutorial002_an_py310.py hl[17:19] *}

## 라우터에서의 커스텀 `APIRoute` 클래스 { #custom-apiroute-class-in-a-router }

`APIRouter`의 `route_class` 파라미터를 설정할 수도 있습니다:

{* ../../docs_src/custom_request_and_route/tutorial003_py310.py hl[26] *}

이 예시에서는 `router` 아래의 *경로 처리*들이 커스텀 `TimedRoute` 클래스를 사용하며, 응답을 생성하는 데 걸린 시간을 담은 추가 `X-Response-Time` 헤더가 응답에 포함됩니다:
