# 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。

## Example { #example }

Here's an example *path operation* with parameters using some of the above types.

{* ../../docs_src/extra_data_types/tutorial001_an_py310.py hl[1,3,12:16] *}

Note that the parameters inside the function have their natural data type, and you can, for example, perform normal date manipulations, like:

			Optional:    true,
		},
		HelpKV{
			Key:         Comment,
			Type:        "sentence",
			Description: DefaultComment,
			Optional:    true,
		},
	}
)

// DefaultHelpPostfix - Helper function to add (default: $value) messages in config help
func DefaultHelpPostfix(subsystem KVS, key string) string {
	val, found := subsystem.Lookup(key)
	if !found || val == "" {
		return ""
	}
