Una alternativa que podrías usar para capturar excepciones (y posiblemente también lanzar otra `HTTPException`) es crear un [Manejador de Excepciones Personalizado](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}.

## Dependencias con `yield` y `except`

예외를 처리하고(또는 추가로 다른 `HTTPException`을 발생시키기 위해) 사용할 수 있는 또 다른 방법은 [사용자 정의 예외 처리기](../handling-errors.md#install-custom-exception-handlers){.internal-link target=_blank}를 생성하는 것 입니다.

## `yield`와 `except`를 사용하는 의존성

`yield`를 사용하는 의존성에서 `except`를 사용하여 예외를 포착하고 예외를 다시 발생시키지 않거나 (또는 새 예외를 발생시키지 않으면), FastAPI는 해당 예외가 발생했는지 알 수 없습니다. 이는 일반적인 Python 방식과 동일합니다:

new_app = UnicornMiddleware(app, some_config="rainbow")
```

But FastAPI (actually Starlette) provides a simpler way to do it that makes sure that the internal middlewares handle server errors and custom exception handlers work properly.

For that, you use `app.add_middleware()` (as in the example for CORS).

```Python
from fastapi import FastAPI
from unicorn import UnicornMiddleware

app = FastAPI()
