Si vous ouvrez la documentation automatique de l'API, votre extension apparaîtra au bas du *chemin* spécifique.

<img src="/img/tutorial/path-operation-advanced-configuration/image01.png">

Et dans le fichier openapi généré (`/openapi.json`), vous verrez également votre extension dans le cadre du *chemin* spécifique :

```JSON hl_lines="22"
{

{!../../docs_src/path_operation_advanced_configuration/tutorial005.py!}
```

Wenn Sie die automatische API-Dokumentation öffnen, wird Ihre Erweiterung am Ende der spezifischen *Pfadoperation* angezeigt.

Und wenn Sie die resultierende OpenAPI sehen (unter `/openapi.json` in Ihrer API), sehen Sie Ihre Erweiterung auch als Teil der spezifischen *Pfadoperation*:

```Python hl_lines="17"

## Check the username

Here's a more complete example.

Use a dependency to check if the username and password are correct.

The interactive API docs will update accordingly, to allow multiple values:

### Query parameter list / multiple values with defaults

And you can also define a default `list` of values if none are provided:

* 同样适用于 `app/routers/users.py`，它是另一个子模块：`app.routers.users`。
* 还有一个子目录 `app/internal/` 包含另一个 `__init__.py` 文件，因此它是又一个「Python 子包」：`app.internal`。
* `app/internal/admin.py` 是另一个子模块：`app.internal.admin`。
