我的Python脚本有一个名为Command的类，我想用CLI命令调用类的方法（类似于python cli-comand.py net get-public-ip）。
我使用了Python click库，但是当我试图执行它时，它抛出了错误TypeError: get_public_ip() missing 1 required positional argument: 'self'。
正如预期的那样，我无法传递self。有没有办法将参数传递到类方法中，或者其他方法？click主要用于函数。
我的Python脚本如下所示：

cli-command文件名.py

import click
import urllib.request
from typing import List, AnyStr
from urllib.error import URLError

from ttn_cli.utils.constants import FETCH_PUBLIC_IP_URL

@click.group()
def cli():
    """
    This is the root function of cli module.
    """
    pass

@cli.group()
def net():
    """
    function act as a group which is linked to root cli function.
    """
    pass

class Command:

    def __init__(self):
        pass

    @net.command()  #  <-- click command
    def get_public_ip(self, *args) -> AnyStr:  # I want to use this method as a cli command
        """
        Function used to get public ip of your host.
        args: List of arguments provided
        """
        try:
            ip = urllib.request.urlopen(FETCH_PUBLIC_IP_URL).read().decode(
                "utf-8")
            return ip
        except URLError:
            return "Please check your internet connectivity"

cmd_network = Command()

def main() -> None:
    """
    This is the main function which returns a shell to user as well
    as can run cli commands directly.
    """
    cli()

if __name__ == "__main__":
    main()
