Avant FastAPI 0.106.0, lever des exceptions après `yield` n’était pas possible, le code d’arrêt dans les dépendances avec `yield` s’exécutait après l’envoi de la réponse, donc les [Gestionnaires d'exceptions](../tutorial/handling-errors.md#install-custom-exception-handlers) avaient déjà été exécutés.

但是如果你需要，它就在这里。🤓

如果你想捕获异常并基于它创建一个自定义响应，请创建一个[自定义异常处理器](../handling-errors.md#install-custom-exception-handlers)。

## 同时使用 `yield` 和 `except` 的依赖项 { #dependencies-with-yield-and-except }

如果你在带有 `yield` 的依赖中使用 `except` 捕获了一个异常，并且你没有再次抛出它（或抛出一个新异常），FastAPI 将无法察觉发生过异常，就像普通的 Python 代码那样：

async def create_items(items: ItemList):
    return items

```

FastAPI supports these type annotations and will create a Pydantic `TypeAdapter` for them, so that types can work as normally and there's no need for the custom logic and types in RootModels.

## Use one HTTP operation per function

Don't mix HTTP operations in a single function, having one function per HTTP operation helps separate concerns and organize the code.

Do this:

{* ../../docs_src/dependencies/tutorial008b_an_py310.py hl[18:22,31] *}

Si quieres capturar excepciones y crear un response personalizado en base a eso, crea un [Manejador de Excepciones Personalizado](../handling-errors.md#install-custom-exception-handlers).
