Question

我只是使用netmiko模块在CISCO交换机设备上玩，并在json文件中使用我的凭据，如IP地址，密码，用户名，并将该json文件调用到python脚本中以获取这些详细信息。在执行此操作时我收到了广告错误，我已在下面提供了详细信息，请说明我做错了什么......

$ cat CiscoNet_6.py
#!/usr/bin/python3
from __future__ import absolute_import, division, print_function
import netmiko
import paramiko
import json
######################################

# creating a tuple
netmiko_exceptions = (netmiko.ssh_exception.NetMikoAuthenticationException,
                              netmiko.ssh_exception.NetMikoTimeoutException)

with open('devices.json') as dev_file:
    devices = json.load(dev_file)

for device in devices:
    try:
        print('-'*79)
        print('Net Device Address Is: -->', device['ip'])
        #print('Net Device Address Is: -->', device)
        connection = netmiko.ConnectHandler(**device)
        print(connection.send_command('show clock'))
        print('-'*79)
        connection.disconnect()
    except netmiko_exceptions as e:
        #print('Authentication failed to', 'Device')
        print('Failed to', device['ip'], e)
        #print('Failed to', device, e)

我的JSON文件devices.json：

[
 {
  "ip: "192.168.0.200",
  "device_type": "cisco_ios",
  "username": "nettest",
  "password": "cisco123"
 }
]

错误：

Traceback (most recent call last):
  File "./CiscoNet_6.py", line 18, in <module>
    devices = json.load(dev_file)
  File "/python/v3.6.1/lib/python3.6/json/__init__.py", line 299, in load

Answer 1

也许这就是为什么

"ip*"*: "192.168.0.200",

json.decoder.JSONDecodeError在python3中调用json文件时出错
