用户信息通过是点击功能

Question

我正在使用 ssh 工具与学校服务器建立 ssh 连接，该示例我正在使用来自源的示例来建立 ssh 连接。我的问题是我不想要任何用户输入提示但是弹出一个提示说主机的真实性无法建立，用户需要按是继续，我如何编码它让程序接受提示自己。

Session session = jsch.getSession(user, host, 22);
//username and host I can input directly into program so thats not a problem
// username and password will be given via UserInfo interface.
UserInfo ui = new MyUserInfo();

//this is the part that uses the UserInfo, which pulls up a prompt
//how can I code the prompt to automatically choose yes?    
session.setUserInfo(ui);
session.setPassword("password");
session.connect();
String command = JOptionPane.showInputDialog("Enter command", "set|grep SSH");

Answer 1

我们使用下面的代码：

try {
    session = jsch.getSession(user, host, port);
}
catch (JSchException e) {
    throw new TransferException("Failed to open session - " + params, e);
}

session.setPassword(password);

//  Create UserInfo instance in order to support SFTP connection to any machine 
//  without a key username and password will be given via UserInfo interface.
UserInfo userInfo = new SftpUserInfo();
session.setUserInfo(userInfo);

try {
    session.connect(connectTimeout);
}
catch (JSchException e) {
    throw new TransferException("Failed to connect to session - " + params, e);
}

boolean isSessionConnected = session.isConnected();

最重要的是：

/**
 * Implements UserInfo instance in order to support SFTP connection to any machine without a key.
 */
class SftpUserInfo implements UserInfo {

    String password = null;

    @Override
    public String getPassphrase() {
        return null;
    }

    @Override
    public String getPassword() {
        return password;
    }

    public void setPassword(String passwd) {
        password = passwd;
    }

    @Override
    public boolean promptPassphrase(String message) {
        return false;
    }

    @Override
    public boolean promptPassword(String message) {
        return false;
    }

    @Override
    public boolean promptYesNo(String message) {
        return true;
    }

    @Override
    public void showMessage(String message) {
    }
}
