但是如果你需要，你也可以在依赖项中做到这一点。🤓

你还可以创建一个 [自定义异常处理器](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank} 用于捕获异常（同时也可以抛出另一个 `HTTPException`）。

## 包含 `yield` 和 `except` 的依赖项

如果你在包含 `yield` 的依赖项中使用 `except` 捕获了一个异常，然后你没有重新抛出该异常（或抛出一个新异常），与在普通的Python代码中相同，FastAPI不会注意到发生了异常。

These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.

That way you can use your normal editor and coding tools without having to add custom configurations to disregard those errors.

### Einige benutzerdefinierte `tags`, `responses`, und `dependencies` hinzufügen { #add-some-custom-tags-responses-and-dependencies }

Wir fügen weder das Präfix `/items` noch `tags=["items"]` zu jeder *Pfadoperation* hinzu, da wir sie zum `APIRouter` hinzugefügt haben.

### Добавление пользовательских тегов (`tags`), ответов (`responses`) и зависимостей (`dependencies`) { #add-some-custom-tags-responses-and-dependencies }

Мы не будем добавлять префикс `/items` и список тегов `tags=["items"]` для каждого *эндпоинта*, т.к. мы уже их добавили с помощью `APIRouter`.
