File responses will include appropriate `Content-Length`, `Last-Modified` and `ETag` headers.

以非同步串流方式將檔案作為回應。

它在初始化時所需的參數與其他回應型別不同：

- `path` - 要串流的檔案路徑。
- `headers` - 要包含的自訂標頭，字典形式。
- `media_type` - 描述 media type 的字串。若未設定，將根據檔名或路徑推斷 media type。
- `filename` - 若設定，會包含在回應的 `Content-Disposition` 中。

檔案回應會包含適當的 `Content-Length`、`Last-Modified` 與 `ETag` 標頭。

{* ../../docs_src/custom_response/tutorial009_py310.py hl[2,10] *}

你也可以使用 `response_class` 參數：

        final String name = pi.getName();
        final String encodedName = URLEncoder.encode(name, Constants.UTF_8_CHARSET).replace("+", "%20");
        response.header("Content-Disposition", "attachment; filename=\"" + name + "\"; filename*=utf-8''" + encodedName);
        response.header("Pragma", "no-cache");
        response.header("Cache-Control", "no-cache");
