为使用JSch通过SSH执行的命令提供输入/子命令

Question

我正在尝试使用Jcraft Jsch库通过Java应用程序管理路由器。我正在尝试通过TFTP服务器发送路由器配置。问题出在我的Java代码中，因为它可以与PuTTY一起使用。这是我的Java代码：int port=22;String name ="R1";String ip ="192.168.18.100";String password ="root";JSch jsch = new JSch();Session session = jsch.getSession(name, ip, port);session.setPassword(password);session.setConfig("StrictHostKeyChecking", "no");System.out.println("Establishing Connection...");session.connect();System.out.println("Connection established.");ChannelExec channelExec = (ChannelExec)session.openChannel("exec");InputStream in = channelExec.getInputStream();channelExec.setCommand("enable");channelExec.setCommand("copy run tftp : ");//Setting the ip of TFTP server channelExec.setCommand("192.168.50.1 : ");// Setting the name of filechannelExec.setCommand("Config.txt ");channelExec.connect();BufferedReader reader = new BufferedReader(new InputStreamReader(in));String line;int index = 0;StringBuilder sb = new StringBuilder();while ((line = reader.readLine()) != null){    System.out.println(line);}session.disconnect();我懂了该行具有无效的自动命令“ 192.168.50.1”问题是我该如何运行那些连续的命令。

Answer 1

ChannelExec.setCommand多次呼叫无效。

即使有，我也会猜到192.168.50.1 :和Config.txt不是命令，而是命令的输入copy run tftp :，不是吗？

如果是这种情况，则需要将它们写入命令输入中。

像这样：

ChannelExec channel = (ChannelExec) session.openChannel("exec");

channelExec.setCommand("copy run tftp : ");

OutputStream out = channelExec.getOutputStream();

channelExec.connect();

out.write(("192.168.50.1 : \n").getBytes());

out.write(("Config.txt \n").getBytes());

out.flush();
