pexpect 并发送“回车键"问题 [英] pexpect and sending an "Enter Key" issues

问题描述

我在 python 2.7 中使用 pexpect.我目前正在编写一个脚本来登录跳转服务器，然后登录到一些 cisco 设备以自动方式执行一些操作.

I am using pexpect with python 2.7. I am currently writing a script to login to a jump server and then subsequently login to some cisco devices to perform some operations in an automated way.

在登录过程中有一个阶段，我需要通过按键盘上的Enter/Return"来发送一个空行.在阅读了许多帖子和其他论坛后，我尝试了以下方法:

There is a stage during the login process, where I need to send just a blank line by pressing 'Enter/Return' on the keyboard. After reading many of the posts and other forums, I have tried the following:

<handler>.sendline()
<handler>.sendline('')
<handler>.send('\013')

然而，这些似乎都不适合我.当我手动登录到服务器并尝试按 Enter/Return 时，我在屏幕上看到一个C"并且登录过程继续进行.

However, none of these seem to work for me. When I do login manually to the server and attempt to hit Enter/Return, I see a "C" on the screen and the login process proceeds forward.

我不确定C"是什么意思，但是如果有人可以在这里提供帮助或提供一些见解，那将非常有帮助.

I am not sure what the "C" means, however if anyone can help or provide some insight here, it would be really helpful.

推荐答案

sendline() 应该可以工作.可以参考pexpect中pxssh的实现.https://github.com/pexpect/pexpect/blob/master/pexpect/pxssh.py

sendline() should be work. You can refer to the implementation of pxssh in pexpect. https://github.com/pexpect/pexpect/blob/master/pexpect/pxssh.py
