* `PUT` : pour mettre à jour des données.
* `DELETE` : pour supprimer des données.

Donc, dans OpenAPI, chacune des méthodes HTTP est appelée une « opération ».

Nous allons donc aussi les appeler « opérations ».

* `PUT`: um Daten zu aktualisieren (update).
* `DELETE`: um Daten zu löschen (delete).

In OpenAPI wird folglich jede dieser HTTP-Methoden als „Operation“ bezeichnet.

Wir werden sie auch „**Operationen**“ nennen.

Bunu tanımlayan parametre `default_response_class`’tır.

Aşağıdaki örnekte **FastAPI**, tüm *path operations* için varsayılan olarak JSON yerine `HTMLResponse` kullanır.

/// tip | İpucu

Daha önce olduğu gibi, *path operations* içinde `response_class`’ı yine override edebilirsiniz.

有时，我们要为整个应用添加依赖项。

通过与[将 `dependencies` 添加到*路径操作装饰器*](dependencies-in-path-operation-decorators.md) 类似的方式，可以把依赖项添加至整个 `FastAPI` 应用。

这样一来，就可以为所有*路径操作*应用该依赖项：

{* ../../docs_src/dependencies/tutorial012_an_py310.py hl[17] *}

[将 `dependencies` 添加到*路径操作装饰器*](dependencies-in-path-operation-decorators.md) 一章的思路均适用于全局依赖项， 在本例中，这些依赖项可以用于应用中的所有*路径操作*。

## 为一组路径操作定义依赖项 { #dependencies-for-groups-of-path-operations }

def use_route_names_as_operation_ids(app: FastAPI) -> None:
    """
    Simplify operation IDs so that generated API clients have simpler function
    names.

    Should be called only after all routes have been added.
    """
    for route in app.routes:
        if isinstance(route, APIRoute):
            route.operation_id = route.name  # in this case, 'read_items'

## Features { #features }

- **Path Operation Explorer** - A sidebar tree view of all <dfn title="routes, endpoints">*path operations*</dfn> in your application. Click to jump to any route or router definition.

Swagger UI will handle it behind the scenes for you, but it needs this "redirect" helper.
