我目前正在尝试使用pexpect控制到我的树莓派的简单ssh连接,我将其用于某些智能家居控件。
我刚刚开始使用它,我正在从一个学期的书“ Violent Python”的帮助下学习它。
我在Windows上,并了解到pexpect.spawn
对象在Windows上不可用。在文档中,有人说我必须改用PopenSpawn
。我有一个简单的脚本:
import traceback
import pexpect
from pexpect.popen_spawn import PopenSpawn
try:
child = pexpect.popen_spawn.PopenSpawn('ssh [email protected]')
a = child.expect(['password:', 'The authenticity of host'], timeout=300, async=True)
if a == 0:
child.sendline('123456789')
print('this ip has exists in know_host files!')
if a == 1:
print('this ip will be added to know_host files!')
child.sendline('yes')
child.expect('password:')
child.sendline('raspberry')
# send test
child.sendline("echo TestMessage")
child.interact()
except pexpect.EOF:
traceback.print_exc()
这总是会给我这个错误:
Traceback (most recent call last):
File "D:/CENSORED/pexpect-master/sshforpi2.py", line 6, in <module>
child = pexpect.popen_spawn.PopenSpawn('ssh [email protected]')

[我发现this teddyjoe个人在问同样的事情-他还没有得到答案。
SSH不是Windows命令的本机。在下面的线路图命令中,指向C:\ Windows \ System32 \ OpenSSH中的ssh。现在,OpenSSH已添加到System32中的Windows 10中。试试这个,我认为它可能对您有用。
child = pexpect.popen_spawn.PopenSpawn('ssh [email protected]')
尝试此操作
command = 'C:\Windows\system32\OpenSSH\ssh.exe [email protected]'
child = pexpect.popen_spawn.PopenSpawn(command)
