与netmiko的多个设备连接

Question

我有一个我无法解决的问题。

我有这样的剧本：

from netmiko import ConnectHandler

cisco_ios = []

sandbox_cisco = {
    "device_type":"cisco_ios",
    "host":"sandbox-iosxe-latest-1.cisco.com",
    "port":"22",
    "username":"developer",
    "password":"C1sco12345"
    }
cisco_ios.append(sandbox_cisco)

sandbox_cisco_2 = {
    "device_type":"cisco_ios",
    "host":"sandbox-iosxr-1.cisco.com",
    "port":"22",
    "username":"admin",
    "password":"C1sco12345"
    }
cisco_ios.append(sandbox_cisco_2)


command = "show interfaces description"

def get_interface(command,**kwargs):

    for ne in kwargs:
        net_connect = ConnectHandler(**ne)
        comando = net_connect.send_command(command)
        net_connect.disconnect()
        print(comando)

get_interface(command,cisco_ios) #line 35

它给了我以下错误：

 line 35, in <module>
    get_interface(command,cisco_ios)
TypeError: get_interface() takes 1 positional argument but 2 were given

如果我在第35行中添加"**“，它将返回以下错误：

line 35, in <module>
    get_interface(command, **cisco_ios)
TypeError: __main__.get_interface() argument after ** must be a mapping, not list

你能帮帮我吗?我不知道我做错了什么

cisco_ios是一个列表，所以您应该这样做：

def get_interface(command, devices):

    for ne in devices:
        net_connect = ConnectHandler(**ne)
        comando = net_connect.send_command(command)
        net_connect.disconnect()
        print(comando)

供你参考。kwargs用于将多个关键字参数传递给函数
