This is a somewhat advanced technique, and in most of the cases you won't really need it, as you can raise exceptions (including `HTTPException`) from inside of the rest of your application code, for example, in the *path operation function*.

But it's there for you if you need it. 🤓

## Partager des dépendances `Annotated` { #share-annotated-dependencies }

Dans les exemples ci-dessus, vous voyez qu’il y a un tout petit peu de **duplication de code**.

Lorsque vous devez utiliser la dépendance `common_parameters()`, vous devez écrire tout le paramètre avec l’annotation de type et `Depends()` :

```Python

    email = user_dict["email"],
    full_name = user_dict["full_name"],
    disabled = user_dict["disabled"],
    hashed_password = user_dict["hashed_password"],
)
```

/// info

Pour une explication plus complète de `**user_dict`, consultez [la documentation pour **Modèles supplémentaires**](../extra-models.md#about-user-in-dict).

## Renvoyer le jeton { #return-the-token }

### `shutdown` 事件 { #shutdown-event }

使用事件 `"shutdown"` 声明一个在应用关闭时运行的函数：

{* ../../docs_src/events/tutorial002_py310.py hl[6] *}

此处，`shutdown` 事件处理器函数会向文件 `log.txt` 写入一行文本 `"Application shutdown"`。

/// info | 信息

在 `open()` 函数中，`mode="a"` 指的是“追加”。因此这行文本会添加在文件已有内容之后，不会覆盖之前的内容。

///

/// tip | 提示

注意，本例使用 Python 标准的 `open()` 函数与文件交互。

这个函数执行 I/O（输入/输出）操作，需要“等待”内容写进磁盘。
