如何添加到此code，使之从该文件夹下载的所有文件？

How can I add to this code to make it download all the files from that folder?

推荐答案

我会建议你有在服务器端，它首先给你所有的文件列表中文件夹内的脚本，然后将应用程序下载的每个文件中的一个由之一。

I would suggest you to have a script at server's end, which first gives you list of all the files inside a folder, and then your application downloads each file one by one.
