# 回應標頭 { #response-headers }

## 使用 `Response` 參數 { #use-a-response-parameter }

你可以在你的*路徑操作函式（path operation function）*中宣告一個 `Response` 型別的參數（就像處理 Cookie 一樣）。

然後你可以在那個*暫時性的* `Response` 物件上設定標頭。

{* ../../docs_src/response_headers/tutorial002_py310.py hl[1, 7:8] *}

接著你可以像平常一樣回傳任何你需要的物件（`dict`、資料庫模型等）。

如果你宣告了 `response_model`，它仍會用來過濾並轉換你回傳的物件。

FastAPI 會使用那個暫時性的回應來擷取標頭（還有 Cookie 與狀態碼），並把它們放到最終回應中；最終回應包含你回傳的值，且會依任何 `response_model` 進行過濾。

## Usando `BackgroundTasks` { #using-backgroundtasks }

Primeiro, importe `BackgroundTasks` e defina um parâmetro na sua *função de operação de rota* com uma declaração de tipo `BackgroundTasks`:

{* ../../docs_src/background_tasks/tutorial001_py310.py hl[1,13] *}

O **FastAPI** criará o objeto do tipo `BackgroundTasks` para você e o passará como esse parâmetro.

## Crie uma função de tarefa { #create-a-task-function }
