如果你想攔截例外並據此回傳自訂回應，請建立一個[自訂例外處理器](../handling-errors.md#install-custom-exception-handlers)。

## 含 `yield` 與 `except` 的相依 { #dependencies-with-yield-and-except }

如果你在含 `yield` 的相依中用 `except` 攔截了例外，且沒有再次拋出它（或拋出新的例外），FastAPI 將無法察覺有例外發生，就像在一般的 Python 中一樣：

{* ../../docs_src/dependencies/tutorial008c_an_py310.py hl[15:16] *}

在這種情況下，客戶端會如預期地看到一個 *HTTP 500 Internal Server Error* 回應（因為我們沒有拋出 `HTTPException` 或類似的東西），但伺服器將不會有任何日誌或其他錯誤線索。😱
