Question

我尝试通过SSH连接到服务器并为我的命令获取输出。如果我进入System.out，一切正常。否则，如果我想将它放入JTextPane，它会说明，但MC是不可读的。

这是我的代码：

JSch jsch = new JSch();

String command = "";
String commandR = "";
host = null;

if (arg.length > 1) {
    host = arg[0];
    command = arg[2];
    commandR = arg[3];
}

String user = host.substring(0, host.indexOf('@'));
host = host.substring(host.indexOf('@') + 1);
Session session = jsch.getSession(user, host, 22);
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);

session.setPassword(arg[1]);
if (!session.isConnected()) {
    session.connect();
}

Channel channel = session.openChannel("shell");

String ans = " ";
InputStream in = channel.getInputStream();
OutputStream out = channel.getOutputStream();
//channel.setInputStream(System.in);
if (!channel.isConnected()) {
    channel.connect(10 * 1000);
}
boolean logon = false;
boolean started = false;
boolean brtuser = false;
boolean log = false;
byte[] tmp = new byte[1024];

JFrame j = new JFrame();
JTextPane jj = new JTextPane();
jj.setContentType("text/html");
StyledDocument  doc = (StyledDocument )jj.getDocument();
jj.setPreferredSize(new Dimension(500, 600));
j.setDefaultCloseOperation(2);
j.add(new JScrollPane(jj));
j.pack();
j.setVisible(true);
while (!started) {

    while (in.available() > 0) {
        int i = in.read(tmp, 0, 1024);
        if (i < 0) {
            break;
        }

        // jj.append();

        doc.insertString(doc.getLength(), new String(tmp, 0, i), null);
        ans += new String(tmp, 0, i);
        System.out.print(new String(tmp, 0, i));

然后我写pwd和mc - pwd我很好，但mc就是

请帮我看看它！

＆＃34;垃圾＆＃34;您在JTextPane中看到的是ANSI escape codes。这些定义了颜色和其他格式。 Midnight Commander（和其他应用程序）使用它们在文本控制台上呈现类似GUI的界面。

终端/ SSH客户端（如PuTTY）可以理解ANSI转义码。即使是各种操作系统（例如Windows）中的控制台窗口。这可能就是为什么当你将输出打印到System.out时看起来很好。

但JTextPane无法理解它们，它会按原样显示它们。

请参阅ANSI colors in Java Swing text fields了解＆＃34; ANSI着色JTextPane子类＆＃34;。
