) -> dict[str, Any]:
    users: dict[str, Any] = {}
    for user, count in counter.most_common():
        if count >= min_count:
            author = authors[user]
            users[user] = {
                "login": user,
                "count": count,
                "avatarUrl": author.avatarUrl,

Como `/users/me`, digamos que seja para obter dados sobre o usuário atual.

E então você também pode ter um path `/users/{user_id}` para obter dados sobre um usuário específico por algum ID de usuário.

Como as *operações de rota* são avaliadas em ordem, você precisa garantir que o path para `/users/me` seja declarado antes do de `/users/{user_id}`:

接下来的章节会介绍其中的好几种。

## 顺序很重要 { #order-matters }

有时，*路径操作*中的路径是写死的。

比如要使用 `/users/me` 获取当前用户的数据。

然后还要使用 `/users/{user_id}`，通过用户 ID 获取指定用户的数据。

由于*路径操作*是按顺序依次运行的，因此，一定要在 `/users/{user_id}` 之前声明 `/users/me` ：

{* ../../docs_src/path_params/tutorial003_py310.py hl[6,11] *}

否则，`/users/{user_id}` 将匹配 `/users/me`，FastAPI 会**认为**正在接收值为 `"me"` 的 `user_id` 参数。

同样，你不能重复定义一个路径操作：

這些之中的好幾個會在接下來的教學章節中介紹。

## 順序很重要 { #order-matters }

在建立「路徑操作」時，你可能會遇到有固定路徑的情況。

像是 `/users/me`，假設它用來取得目前使用者的資料。

然後你也可能有一個路徑 `/users/{user_id}` 用來依使用者 ID 取得特定使用者的資料。

因為「路徑操作」會依宣告順序來比對，你必須確保 `/users/me` 的路徑在 `/users/{user_id}` 之前宣告：

{* ../../docs_src/path_params/tutorial003_py310.py hl[6,11] *}

否則，`/users/{user_id}` 的路徑也會匹配 `/users/me`，並「認為」它收到一個值為 `"me"` 的 `user_id` 參數。

同樣地，你不能重新定義同一路徑操作：

from fastapi import FastAPI

app = FastAPI()


@app.get("/items/", tags=["items"])
async def read_items():
    return [{"name": "Foo", "price": 42}]


@app.get("/users/", tags=["users"])
async def read_users():
    return [{"username": "johndoe"}]


@app.get("/elements/", tags=["items"], deprecated=True)
async def read_elements():

    without any of its other classes -- but is also available in a second
    "version" that omits the class to avoid conflicts with the copy in Guava
    itself. The idea is:

    - If users want only ListenableFuture, they depend on listenablefuture-1.0.

    - If users want all of Guava, they depend on guava, which, as of Guava
    27.0, depends on
    listenablefuture-9999.0-empty-to-avoid-conflict-with-guava. The 9999.0-...

app = FastAPI()

router = APIRouter()


@router.get("/users/{id}")
def read_user(segment: str, id: str):
    return {"segment": segment, "id": id}


app.include_router(router, prefix="/{segment}")


client = TestClient(app)


def test_get():
    response = client.get("/seg/users/foo")
    assert response.status_code == 200, response.text
