但如果你直接回傳一個 `Response`（或其子類別，例如 `JSONResponse`），資料將不會被自動轉換（即使你宣告了 `response_model`），而且文件也不會自動產生（例如，在產生的 OpenAPI 中包含 HTTP 標頭 `Content-Type` 的特定「media type」）。

你也可以在「路徑操作裝飾器」中使用 `response_class` 參數，宣告要使用的 `Response`（例如任意 `Response` 子類別）。

你從「路徑操作函式」回傳的內容，會被放進該 `Response` 中。

/// note

若你使用的回應類別沒有 media type，FastAPI 會假設你的回應沒有內容，因此不會在產生的 OpenAPI 文件中記錄回應格式。

You don't have to worry about performance when including routers.

This will take microseconds and will only happen at startup.

So it won't affect performance. ⚡
