jsch - 如何处理expectj中的密码提示

Question

我想通过expectj（实际上是jsch）发送“su root”命令。它要求密码。有没有办法在 expectj 中处理它？

Answer 1

    ExpectJ ex = new ExpectJ(30);
    Spawn spawn = ex.spawn(new SshSpawn("192.168.56.101", 22, "alice", "alicepassword"));
    spawn.send("su root\n");
    spawn.expect("assword");
    spawn.send("yourpassword\n");
    try{
        spawn.interact();   
    }catch(NullPointerException npe){   
        //ignore, seems like some strange expectj bug
    }
