Ve router’daki tüm *path operation*’lara eklenecek, her request için çalıştırılıp çözülecek bir `dependencies` listesi de ekleyebiliriz.

[ *path operation decorator*’larındaki dependency’lerde](dependencies/dependencies-in-path-operation-decorators.md) olduğu gibi, *path operation function*’ınıza herhangi bir değer aktarılmayacağını unutmayın.

Notez que `response_model` est un paramètre de la méthode « decorator » (`get`, `post`, etc.). Pas de votre *fonction de chemin d'accès*, comme tous les paramètres et le corps.

Similar a como puedes [agregar `dependencies` a los *path operation decorators*](dependencies-in-path-operation-decorators.md), puedes agregarlos a la aplicación de `FastAPI`.

En ese caso, se aplicarán a todas las *path operations* en la aplicación:

그리고 router의 모든 *path operations*에 추가될 `dependencies` 목록도 추가할 수 있으며, 해당 경로들로 들어오는 각 요청마다 실행/해결됩니다.

[*path operation decorator의 dependencies*](dependencies/dependencies-in-path-operation-decorators.md)와 마찬가지로, *path operation function*에 어떤 값도 전달되지 않습니다.

최종적으로 item 경로는 다음과 같습니다:

* `/items/{item_id}`

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。
