# 回應 Cookie { #response-cookies }

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

你可以在路徑操作函式（path operation function）中宣告一個型別為 `Response` 的參數。

接著你可以在那個「暫時」的 `Response` 物件上設定 Cookie。

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

之後如常回傳你需要的任何物件（例如 `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 會使用那個暫時的 `Response` 取出 Cookie（以及標頭與狀態碼），並將它們放入最終回應；最終回應包含你回傳的值，且會套用任何 `response_model` 的過濾。

        }

        @Override
        public String getHeader(String name) {
            return headers.get(name);
        }

        @Override
        public void addCookie(jakarta.servlet.http.Cookie cookie) {
        }

        @Override
        public boolean containsHeader(String name) {
            return headers.containsKey(name);
        }

        @Override

# レスポンスの Cookie { #response-cookies }

## `Response` パラメータを使う { #use-a-response-parameter }

*path operation 関数*で `Response` 型のパラメータを宣言できます。

そして、その*一時的*なレスポンスオブジェクトに Cookie を設定できます。

{* ../../docs_src/response_cookies/tutorial002_py310.py hl[1, 8:9] *}

その後は通常どおり、必要な任意のオブジェクト（`dict`、データベースモデルなど）を返せます。

`response_model` を宣言している場合でも、返したオブジェクトは引き続きフィルタおよび変換されます。

    elif field_info_in == params.ParamTypes.header:
        dependant.header_params.append(field)
    else:
        assert field_info_in == params.ParamTypes.cookie, (
            f"non-body parameters must be in path, query, header or cookie: {field.name}"
        )
        dependant.cookie_params.append(field)

`Response` parametresini dependency'lerde de tanımlayıp, onların içinde cookie (ve header) set edebilirsiniz.

## Doğrudan bir `Response` döndürün { #return-a-response-directly }

Kodunuzda doğrudan bir `Response` döndürürken de cookie oluşturabilirsiniz.

Bunu yapmak için, [Doğrudan Response Döndürme](response-directly.md) bölümünde anlatıldığı gibi bir response oluşturabilirsiniz.

/// tip

Here we are using `Query()` because this is a **query parameter**. Later we will see others like `Path()`, `Body()`, `Header()`, and `Cookie()`, that also accept the same arguments as `Query()`.

///

FastAPI will now:

* **Validate** the data making sure that the max length is 50 characters
