j2ssh远程到远程文件传输

Question

以下代码适用于 localhost 到远程服务器。但是我的应用程序在单独的服务器上运行，所以我需要从 remote1 服务器中选择文件，然后将其放入 remote2 服务器。如何使用 J2SSH。

不确定我是否理解您的问题......

如果您只有对两台服务器的 SFTP 访问权限，并且您的代码在本地运行（在客户端上），那么您唯一的选择是下载文件并将其上传到另一台服务器。如果您可以通过 SSH 访问服务器 1，那么您可以创建一个脚本，将文件上传/下载到服务器 2。

如果您的代码在server1上运行并且您需要将文件从server1上传到server2，那么当您将代码从client1上传到server2时，它与您当前的情况有什么不同（除了本地路径不同） ?
