您必须将所有文件包含在一个zip中并下载zip，否则客户端需要制作多个请求和每个请求将下载一个文件。每个请求只能下载一个文件，因为每个请求只能有一个响应。

You'd have to include all files in one zip and download the zip, or the client will need to make multiple requests and each request will download one file. You can only download one file per request as each request can only have one response.
