但如果你宣告了回應模型或回傳型別，將會直接用它來把資料序列化為 JSON，並直接回傳具有正確 JSON media type 的回應，而不會使用 `JSONResponse` 類別。

這是取得最佳效能的理想方式。

///

### `RedirectResponse` { #redirectresponse }

回傳一個 HTTP 重新導向。預設使用 307 狀態碼（Temporary Redirect）。

你可以直接回傳 `RedirectResponse`：

{* ../../docs_src/custom_response/tutorial006_py310.py hl[2,9] *}

或者你可以在 `response_class` 參數中使用它：
