我想使用SSH来自动执行命令，但是当它运行时会出现一条消息，键入是或否。可以在一行命令中或在paramiko中以某种方式回答此消息。
我尝试了很多类似的事情。
sudo /usr/sbin/service-maintenance-window ; yes
sudo /usr/sbin/service-maintenance-window | yes
yes | sudo /usr/sbin/service-maintenance-window
yes | sudo /usr/sbin/service-maintenance-window
代码如下：
from paramiko import SSHClient
import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect("xxxx", username="xxxx", password="xxxx",timeout=5)
stdin,stdout,stderr = ssh.exec_command("yes | sudo /usr/sbin/service-maintenance-window")
print(stdout.read())
我要接受的消息是：
------------------------------ WARNING ---------------------------------------
