Exception’ı, **FastAPI**’nin aynı varsayılan exception handler’larıyla birlikte kullanmak isterseniz, varsayılan exception handler’ları `fastapi.exception_handlers` içinden import edip yeniden kullanabilirsiniz:

{* ../../docs_src/handling_errors/tutorial006_py310.py hl[2:5,15,21] *}

```Python
from starlette.exceptions import HTTPException as StarletteHTTPException
```

### 复用 **FastAPI** 的异常处理器 { #reuse-fastapis-exception-handlers }

如果你想在自定义处理后仍复用 **FastAPI** 的默认异常处理器，可以从 `fastapi.exception_handlers` 导入并复用这些默认处理器：

{* ../../docs_src/handling_errors/tutorial006_py310.py hl[2:5,15,21] *}

```Python
from starlette.exceptions import HTTPException as StarletteHTTPException
```

### **FastAPI**의 예외 핸들러 재사용하기 { #reuse-fastapis-exception-handlers }

예외를 사용하면서 **FastAPI**의 동일한 기본 예외 핸들러도 함께 사용하고 싶다면, `fastapi.exception_handlers`에서 기본 예외 핸들러를 가져와 재사용할 수 있습니다:

{* ../../docs_src/handling_errors/tutorial006_py310.py hl[2:5,15,21] *}

If you want to use the exception along with the same default exception handlers from  **FastAPI**, you can import and reuse the default exception handlers from `fastapi.exception_handlers`:

{* ../../docs_src/handling_errors/tutorial006_py310.py hl[2:5,15,21] *}

```Python
from starlette.exceptions import HTTPException as StarletteHTTPException
```

### 重用 **FastAPI** 的例外處理器 { #reuse-fastapis-exception-handlers }

如果你想在使用例外的同時，沿用 **FastAPI** 的預設例外處理器，你可以從 `fastapi.exception_handlers` 匯入並重用預設的處理器：

{* ../../docs_src/handling_errors/tutorial006_py310.py hl[2:5,15,21] *}

```Python
from starlette.exceptions import HTTPException as StarletteHTTPException
```

### **FastAPI** の例外ハンドラの再利用 { #reuse-fastapis-exception-handlers }

**FastAPI** から同じデフォルトの例外ハンドラと一緒に例外を使用したい場合は、`fastapi.exception_handlers`からデフォルトの例外ハンドラをインポートして再利用できます:

{* ../../docs_src/handling_errors/tutorial006_py310.py hl[2:5,15,21] *}
