使用 JSCH 将文件从一台远程服务器发送到另一台使用 JSCH 的服务器 [英] Send files from one remote server using JSCH to another server using JSCH too

问题描述

我想将文件从我的第一个远程服务器发送到另一个:

I would like to send files from my first remote server to another one:

public boolean uploadFile() throws JSchException, SftpException {
        ChannelSftp channelSftpA = createChannelSftp();
        ChannelSftp channelSftpB = createChannelSftp();
        channelSftpA.connect();
        channelSftpB.connect();

        localFilePath = "/data/upload/readme.txt";
        remoteFilePath = "/bingo/pdf/";

        channelSftpA.cd(localFilePath);
        channelSftpA.put(localFilePath + "readme.txt", remoteFilePath + "readme.txt");

但它不起作用.我应该将 channelB.put 放入我的第一个 channelA.put 中吗?

But it doesn't work. Should I put channelB.put into my first channelA.put?

推荐答案

如果我理解你的问题是正确的，你的代码将从第三台服务器运行，为了传输文件，你应该从 服务器 A 获取文件，然后放在 server B 上.顺便说一下，您要下载和上传文件的用户应该有权访问指定的文件夹！

If I understood your question correct, you code will be run from third server, for transferring file you should get file from server A, and that put on server B. By the way users under which you are going to download and upload files should have access to specified folders!

private boolean transferFile() throws JSchException, SftpException {
        ChannelSftp channelSftpA = createChannelSftp();
        ChannelSftp channelSftpB = createChannelSftp();
        channelSftpA.connect();
        channelSftpB.connect();

        String fileName = "readme.txt";
        String remoteFilePathFrom = "/folderFrom/";
        String remoteFilePathTo = "/folderTo/";

        InputStream srcInputStream = channelSftpA.get(remoteFilePathFrom + fileName);
        channelSftpB.put(srcInputStream, remoteFilePathTo + fileName);
        System.out.println("Transfer has been completed");

        channelSftpA.exit();
        channelSftpB.exit();
        return true;
    }
