When creating *path operations*, you can find situations where you have a fixed path.

Like `/users/me`, let's say that it's to get data about the current user.

And then you can also have a path `/users/{user_id}` to get data about a specific user by some user ID.

Because *path operations* are evaluated in order, you need to make sure that the path for `/users/me` is declared before the one for `/users/{user_id}`:

```Python hl_lines="6  11"

Например, `/users/me`. Предположим, что это путь для получения данных о текущем пользователе.

У вас также может быть путь `/users/{user_id}`, чтобы получить данные о конкретном пользователе по его ID.

Поскольку *операции пути* выполняются в порядке их объявления, необходимо, чтобы путь для `/users/me` был объявлен раньше, чем путь для `/users/{user_id}`:

下一章介绍详细内容。

## 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` ：

```Python hl_lines="6  11"
{!../../../docs_src/path_params/tutorial003.py!}
```

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

Tel que `/users/me`, disons pour récupérer les données sur l'utilisateur actuel.

Et vous avez un second chemin : `/users/{user_id}` pour récupérer de la donnée sur un utilisateur spécifique grâce à son identifiant d'utilisateur

Les *fonctions de chemin* étant évaluées dans l'ordre, il faut s'assurer que la fonction correspondant à `/users/me` est déclarée avant celle de `/users/{user_id}` :
