使用SSH命令在python中生成字典

我有一个python脚本，它执行以下故事情节：

• 首先检查所有不需要

  VPN

  连接的

  ip

  ，通过

  SSH

  连接，然后运行

  CAT

  命令

• 然后检查需要

  VPN

  的每个人，连接到

  VPN

  ，并

  SSH

  运行

  CAT

  命令

这部分是功能性的，我的问题是将ssh的输出分配给python字典

#!/usr/bin/python
# -*- coding: utf-8 -*-

from datetime import datetime, date, time, timedelta
import socket
import socks
import paramiko
import sys
import re

# create script head
print ('-----------------------------------------------------------------------------------------')
print ('Initializing UP/DOWN script in: '+str(date.today()))
print ('-----------------------------------------------------------------------------------------')

Ips = {'123.45.44.33': {'customer' : 'webservice'}}
IPsocks = {'176.25.0.61': {'customer' : 'hosting'}}

output = []
outputSocks = []
outfinally = []
outfinallySocks = []
lds_data = {}

for ip in Ips:

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(hostname=ip, username='admin', password="admin")
    output.append((ssh.exec_command('cat /tmp/hosts.txt')[1]).read().decode())
    ssh.close()

    outfinally.append([re.split(r'\s*#\s*',line) for line in output[0].splitlines()])

    for a, b in zip(Ips, outfinally):
        lds_data.update({b[:1] : {'hostname' : b[1:5], 'customer' : Ips[a]['customer']}})

for ip in IPsocks:

    sock=socks.socksocket()
    sock.set_proxy(
        proxy_type=socks.SOCKS5,
        addr='10.0.1.10',
        port=1080,
        username="vpn",
        password="vpn102030"
    )
    sock.connect((ip, 22))

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect('ignored without host key verification', username='admin', password='admin', sock=sock)
    outputSocks.append((ssh.exec_command('cat /tmp/hosts.txt')[1]).read().decode())
    ssh.close()

    outfinallySocks.append([re.split(r'\s*#\s*',line) for line in outputSocks[0].splitlines()])

    for a, b in zip(IPsocks, outfinallySocks):
        lds_data.update({b[:1] : {'hostname' : b[1:5], 'customer' : IPsocks[a]['customer']}})

    print(lds_data)

print ('-----------------------------------------------------------------------------------------')
print ('Script successfully completed')
print ('-----------------------------------------------------------------------------------------')

输出

  File "SCRIPT.py", line 36, in <module>
    lds_data.update({tuple(b[:1]) : {'hostname' : b[1:5], 'customer' : Ips[a]['customer']}})
TypeError: unhashable type: 'list'

---

这很难重现，但假设

b

是一个列表列表，我们可以替换此行的实例：

lds_data.update({b[:1] : {'hostname' : b[1:5], 'customer' : IPsocks[a]['customer']}})

为此：

lds_data.update({tuple(b[0]) : {'hostname' : b[1:5], 'customer' : Ips[a]['customer']}})

这将用扁平元组替换列表列表-这是因为字典中的键不能是列表，因为它们是可变的。代码的潜在问题是您试图将字典键设置为列表

lds_data.update({tuple(b[0]) : {'hostname' : b[1:5], 'customer' : Ips[a]['customer']}})
