UserInfo通过是点击功能

Question

我使用ssh工具来建立到学校服务器的ssh连接，我使用的是一个来自ssh连接源的例子。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yes才能继续，我该如何编写程序以接受提示本身。

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) { 
    } 
}
