使用JSch使用密码进行身份validation时获取“Auth取消”
我正在尝试从Java执行Unix命令。 我正在使用JSch库。
这是我的代码：
try{ Session session = new JSch().getSession("*****", "****", 22); session.setPassword("****"); java.util.Properties config = new java.util.Properties(); config.put("StrictHostKeyChecking", "no"); session.setConfig(config); session.connect(); Channel channel=session.openChannel("exec"); ((ChannelExec)channel).setCommand("pwd"); InputStream in=channel.getInputStream(); byte[] tmp=new byte[1024]; while(in.available()>0){ int i=in.read(tmp, 0, 1024); System.out.print(new String(tmp, 0, i)); } channel.disconnect(); session.disconnect(); }catch(Exception e){ System.out.println(org.apache.commons.lang3.exception.ExceptionUtils.getStackTrace(e)); } 我一直收到“validation取消”错误。 在我可以执行任何操作之前，我无法登录。
这是所要求的日志：

我究竟做错了什么？
您将键盘交互式身份validation设置为首选身份validation方法（这是默认设置）。
但是，您没有实现凭据提示。 setPassword不是（也不能）用于键盘交互式身份validation。
如果您确实想要使用密码validation，请首选：
config.put("PreferredAuthentications", "password");
不用说：如果你关心安全性，不要使用StrictHostKeyChecking=no ！
