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}`:


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

                            "schema": {"title": "User Id", "type": "integer"},
                            "name": "user_id",
                            "in": "path",
                        }
                    ],
                }
            },
            "/users/{user_id}/items/": {
                "post": {
                    "responses": {
                        "200": {

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。
