Paramiko-expect,超时

Question

我正在尝试执行自动备份过程并且一切正常，直到我尝试在此行上使用期望 interact.expect("Enter choice (1-10) or q to quit: ")。我得到的错误是raise socket.timeout() 并且我认为是由expect 中的那个字符串不正确引起的，尽管如果我手动登录并输入我会从shell 中复制确切的内容？有人知道解决这个问题吗？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'.*: '。
