В этом случае они будут применяться ко всем *операциям пути* в приложении:

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

У такому разі вони будуть застосовані до всіх *операцій шляху* в застосунку:

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

Nesse caso, elas serão aplicadas a todas as *operações de rota* da aplicação:

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

Und alle Ideen aus dem Abschnitt über das [Hinzufügen von `dependencies` zu den *Pfadoperation-Dekoratoren*](dependencies-in-path-operation-decorators.md) gelten weiterhin, aber in diesem Fall für alle *Pfadoperationen* in der App.

 * <p>As with other collection types, the modification operations are optional, and should throw
 * {@link UnsupportedOperationException} when they are not implemented. Most implementations should
 * support either all add operations or none of them, all removal operations or none of them, and if
 * and only if all of these are supported, the {@code setCount} methods as well.

# 全域依賴 { #global-dependencies }

在某些類型的應用程式中，你可能想為整個應用程式新增依賴。

類似於你可以在[路徑操作（path operation）的裝飾器中新增 `dependencies`](dependencies-in-path-operation-decorators.md) 的方式，你也可以把它們加到 `FastAPI` 應用程式上。

在這種情況下，它們會套用到應用程式中的所有路徑操作：

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

而且，在[將 `dependencies` 新增到路徑操作裝飾器](dependencies-in-path-operation-decorators.md) 那一節中的所有概念依然適用，只是這裡是套用到整個應用中的所有路徑操作。

For example, when using GraphQL you normally perform all the actions using only `POST` operations.

This is our "**path operation function**":

* **path**: is `/`.
* **operation**: is `get`.
* **function**: is the function below the "decorator" (below `@app.get("/")`).
