如何在expectj中处理密码提示

Question

我想通过expectj (实际上是jsch).It请求密码发送"su root“命令。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
    }
