## 顺序很重要

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.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。

## 预设值

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}`:
