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

Algo como `/users/me` por exemplo, digamos que essa rota seja utilizada para pegar dados sobre o usuário atual.

E então você pode ter também uma rota `/users/{user_id}` para pegar dados sobre um usuário específico associado a um ID de usuário.

Porque as operações de rota são avaliadas em ordem, você precisa ter certeza que a rota para `/users/me` está sendo declarado antes da rota `/users/{user_id}`:

import gradlebuild.binarycompatibility.upgrades.UpgradedProperty.ReplacedAccessor;
import japicmp.model.JApiCompatibility;
import japicmp.model.JApiMethod;
import me.champeau.gradle.japicmp.report.Violation;
import me.champeau.gradle.japicmp.report.ViolationCheckContext;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.UncheckedIOException;

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}` :

    from fastapi import Depends, FastAPI
    from fastapi.security import HTTPBasic, HTTPBasicCredentials

    app = FastAPI()

    security = HTTPBasic()


    @app.get("/users/me")
    def read_current_user(credentials: Annotated[HTTPBasicCredentials, Depends(security)]):
        return {"username": credentials.username, "password": credentials.password}
    ```
