## 模型的清單 { #list-of-models }

同樣地，你可以將回應宣告為物件的 `list`。

為此，使用標準的 Python `list`：

{* ../../docs_src/extra_models/tutorial004_py310.py hl[18] *}

## 以任意 `dict` 作為回應 { #response-with-arbitrary-dict }

你也可以用一般的任意 `dict` 宣告回應，只需指定鍵和值的型別，而不必使用 Pydantic 模型。

當你事先不知道可用的欄位／屬性名稱（定義 Pydantic 模型所需）時，這很實用。

此時可使用 `dict`：

{* ../../docs_src/extra_models/tutorial005_py310.py hl[6] *}

「代理」會攔截原始用戶端請求，並在將其轉交給「應用伺服器」之前加入特殊的「轉發」標頭（`X-Forwarded-*`）。

這些標頭會保留原始請求中原本會遺失的資訊：

* X-Forwarded-For：原始用戶端的 IP 位址
* X-Forwarded-Proto：原始協定（`https`）

	objectName := `\../.minio.sys/config/hello.txt`

	// initialize HTTP NewRecorder, this records any mutations to response writer inside the handler.
	rec := httptest.NewRecorder()
	// construct HTTP request for Get Object end point.
	req, err := newTestSignedRequestV4(http.MethodPut, getPutObjectURL("", bucketName, objectName),

**代理**会拦截原始客户端请求，并在将请求传递给**应用服务器**之前，添加特殊的*转发*请求头（`X-Forwarded-*`）。

这些请求头保留了原始请求中否则会丢失的信息：

- X-Forwarded-For：原始客户端的 IP 地址
- X-Forwarded-Proto：原始协议（`https`）
