我的情况是出现了另一个像密码一样的pop,意味着我需要在密码后输入另一个文本,我还需要以编程方式处理它。
以下代码适用于密码
((ChannelExec)channel).setCommand("cd ~demouser/bin;ls; echo demouser | pbrun democommand");
echo确实可以输入密码。 但就在它之后,我需要像密码一样输入文字而我无法这样做。所以我用管道换了另一个回声,但它没有用。
我正在使用的代码
((ChannelExec)channel).setCommand("cd ~demouser/bin;ls; echo Automation | echo demouser | pbrun democommand");
我也试过下面的推荐并写下如下命令,仍然没有运气
pipe password to sudo
and other data to sudo
ed command
((ChannelExec)channel).setCommand("cd ~demouser/bin;ls; echo Automation | { echo demopass; } | pbrun democommand");
参考截图:
我正在使用的代码:
try {
JSch jsch = new JSch();
Session session = jsch.getSession(user, host, 22);
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);;
session.setPassword(password);
System.out.println("user=="+user+"\n host=="+host);
session.connect();
System.out.println("connected to host ===="+host);
String sudo_pass="demopassword";
Channel channel=session.openChannel("exec");
System.out.println("cd command");
((ChannelExec)channel).setCommand("cd ~demouser/bin;ls; ( echo demopassword && echo Automation ) | pbrun democommand");
((ChannelExec) channel).setPty(true);
InputStream in=channel.getInputStream();
OutputStream out=channel.getOutputStream();
((ChannelExec)channel).setErrStream(System.err);
channel.connect();
out.write((sudo_pass+"\n").getBytes());
out.flush();
byte[] tmp=new byte[1024];
while(true){
while(in.available()>0){
int i=in.read(tmp, 0, 1024);
if(i<0)break;
System.out.print(new String(tmp, 0, i));
}
if(channel.isClosed()){
System.out.println("exit-status: "+channel.getExitStatus());
break;
}
try{Thread.sleep(1000);}catch(Exception ee){}
}
channel.disconnect();
session.disconnect();
}
catch(Exception e){
System.out.println(e);
}
}
任何解决方法都会有所帮助

为命令提供两行输入的Bash语法是:
( echo input1 && echo input2 ) | command
另见Pipe multiple commands into a single command。
您还可以在Java代码中提供输入,而不是使用shell结构:
Providing input/subcommands to command executed over SSH with JSch

感谢马丁以下的方法为我工作
( echo 'command1' && echo 'command2' ) | command
下面的代码适用于我
try {
JSch jsch = new JSch();
Session session = jsch.getSession(user, host, 22);
Properties config = new Properties();
config.put("StrictHostKeyChecking", "no");
session.setConfig(config);;
session.setPassword(password);
System.out.println("user=="+user+"\n host=="+host);
session.connect();
System.out.println("connected to host ===="+host);
String sudo_pass="demo123";
Channel channel=session.openChannel("exec");
System.out.println("cd command");
((ChannelExec)channel).setCommand("cd ~demouser/bin;ls; ( echo 'echo Automation' && echo 'command' ) | pbrun democommand");
((ChannelExec) channel).setPty(true);
InputStream in=channel.getInputStream();
OutputStream out=channel.getOutputStream();
((ChannelExec)channel).setErrStream(System.err);
channel.connect();
out.write((sudo_pass+"\n").getBytes());
out.write(("\n").getBytes());
out.flush();
byte[] tmp=new byte[102400];
while(true){
while(in.available()>0){
int i=in.read(tmp, 0, 102400);
if(i<0)break;
System.out.print(new String(tmp, 0, i));
}
if(channel.isClosed()){
System.out.println("exit-status: "+channel.getExitStatus());
break;
}
try{Thread.sleep(1000);}catch(Exception ee){
ee.printStackTrace();
System.out.println(ee.getMessage());
}
}
channel.disconnect();
session.disconnect();
}
catch(Exception e){
System.out.println(e);
}
}
