我正在尝试执行自动备份过程，并且一切正常，直到我尝试在此行interact.expect("Enter choice (1-10) or q to quit: ")上使用 Expect 为止。我收到的错误是raise socket.timeout()，是由于我认为expect中的字符串不正确而引起的，尽管如果我手动登录并输入我会从 shell 中复制确切的信息？有人知道解决办法吗？谢谢！
import paramiko
from paramiko_expect import SSHClientInteraction
def backup():
# will match root user prompt
root_prompt = '.*# '
# will match Password: or password:
pass_prompt = '.*assword: '
try:
client = paramiko.SSHClient()
client.load_system_host_keys()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname=server, username=user, password=pass)
except paramiko.AuthenticationException:
print("Authentication failed, please verify your credentials: %s")
except paramiko.SSHException as sshException:
print("Unable to establish SSH connection: %s" % sshException)
except paramiko.BadHostKeyException as badHostKeyException:
print("Unable to verify server's host key: %s" % badHostKeyException)
except Exception as e:
print(e.args)
with SSHClientInteraction(client,timeout=10,display=True) as interact:
interact.send('su')
interact.expect(pass_prompt)
interact.send("pass")
interact.expect(root_prompt)
interact.send("BackupMenu")#displays specific menu for backup but menu is not using shell specific commands
interact.expect("Enter choice (1-10) or q to quit: ")
cmd_output_ls = interact.current_output_clean
print cmd_output_ls
client.close()

我已经将上面的代码更新为可行的解决方案。我将
interact.expect("Enter choice (1-10) or q to quit: ")更改为'.*: '。
