在尝试向设备派生时观察TypeError
在尝试向设备派生时观察TypeError
提问于 2018-05-10 07:18:50
我有一台Centos 7笔记本电脑通过LAN端口连接到我的设备。正在尝试登录到我的设备并执行一些命令来执行自动化任务。我在CentOS7上安装了Python3.6.4。下面是我在笔记本电脑上的.py脚本。
#!/usr/local/lib python3.6
import pexpect
import sys
import re
def dologin(child):
# Enter User Name
child.expect ('login:')
child.sendline ('admin')
# Enter Password
child.expect ('Password:')
child.sendline ('123')
return
def doprepcommands(child):
# Enter config prompt
child.expect ('NOS/27179080475072>')
child.sendline ('config')
# Issue command
child.expect ('NOS/27179080475072/DEBUG/Config>')
child.sendline ('show vlan')
child.expect ('NOS/27179080475072/DEBUG/Config>')
child.sendline ('exit')
child.expect ('NOS/27179080475072/DEBUG>')
child.sendline ('exit')
child.expect ('NOS/27179080475072')
child.sendline ('exit')
return
# Spawn the telnet session
child = pexpect.spawn ('telnet 192.168.1.254')
# Display progress on screen
child.logfile = sys.stdout
dologin(child)
doprepcommands(child)我在我的空闲屏幕上观察到下面提到的错误当我通过在不同的博客中找到的细节运行script.Going时，我部分地理解了在我的脚本中错误地使用了'sys.stdout‘(需要在Python2.7和Python3.6中使用不同的用法)。我也在尝试找出我调用的函数'dologin(child)'，'doprepcommands(child)‘是否使用了正确的Python3语法。
我是Python的新手。有没有人能帮我纠正这个错误？

我在不同的博客上通过一些可用的讨论解决了这个问题。我已经用'spawnu‘替换了’spawnu‘，现在我可以远程登录到我的设备，并根据需要执行操作。child.logfile = pexpect.spawn ('telnet 192.168.1.254') child.logfile= sys.stdout
child = pexpect.spawnu ('telnet 192.168.1.254', logfile=sys.stdout, timeout = None)页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
