### 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:

from fastapi import APIRouter

router = APIRouter()


@router.post("/")
async def update_admin():

from ..dependencies import get_token_header

router = APIRouter(
    prefix="/items",
    tags=["items"],
    dependencies=[Depends(get_token_header)],
    responses={404: {"description": "Not found"}},
)


fake_items_db = {"plumbus": {"name": "Plumbus"}, "gun": {"name": "Portal Gun"}}


@router.get("/")
async def read_items():
    return fake_items_db


@router.get("/{item_id}")
async def read_item(item_id: str):

    assert response.json() == {"foo": "baz"}


def test_nested_router():
    app = FastAPI()

    router = APIRouter(prefix="/nested")

    @router.get("/test")
    async def test(var: Annotated[str, Query()] = "bar"):
        return {"foo": var}

    app.include_router(router)

    client = TestClient(app)

    response = client.get("/nested/test")
    assert response.status_code == 200

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

## 在路由器中自訂 `APIRoute` 類別 { #custom-apiroute-class-in-a-router }

你也可以在 `APIRouter` 上設定 `route_class` 參數：

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

在此範例中，`router` 底下的路徑操作會使用自訂的 `TimedRoute` 類別，並在回應中多加上一個 `X-Response-Time` 標頭，標示產生該回應所花費的時間：

		lsrv := &lockServer{
			mutex:   sync.Mutex{},
			lockMap: make(map[string]int64),
		}
		lockServer := lockServerHandler{
			lsrv: lsrv,
		}
		lockServers[i] = lsrv

		router := mux.NewRouter().SkipClean(true)
		subrouter := router.PathPrefix("/").Subrouter()
		subrouter.Methods(http.MethodPost).Path("/v1/health").HandlerFunc(lockServer.HealthHandler)

    yield ServerSentEvent(raw_data="cpu,87.3,1709145600", event="csv")


router = APIRouter()


@router.get("/events", response_class=EventSourceResponse)
async def stream_events():
    yield {"msg": "hello"}
    yield {"msg": "world"}


app.include_router(router, prefix="/api")


@pytest.fixture(name="client")
def client_fixture():
    with TestClient(app) as c:

)

// adminErasureTestBed - encapsulates subsystems that need to be setup for
// admin-handler unit tests.
type adminErasureTestBed struct {
	erasureDirs []string
	objLayer    ObjectLayer
	router      *mux.Router
	done        context.CancelFunc
}
