您可以通过在set_proxy()中创建mitmdump进程对象，并在close_proxy()中调用mitmdump进程对象的stop()方法来停止mitmdump。具体代码示例如下：

from subprocess import Popen

class AddHeader:
    def request(self, flow: http.HTTPFlow) -> None:
        self.num += 1
        if "https://cloud.keytop.cn/service/front/userCenter/lpn/list?_=" in flow.request.pretty_url:
            for name, value in flow.request.headers.items():
                if "accesstoken:" == name:
                    accesstoken = value

addons = [
    AddHeader()
]

def set_proxy():
    """设置系统代理"""
    global mitmdump_process
    pxy.enable = True
    pxy.server = '127.0.0.1:8081'
    pxy.registry_write()
    mitmdump_process = Popen(['mitmdump', '-p', '8081', '-s', __file__])

def close_proxy():
    """关闭系统代理"""
    pxy.enable = False
    pxy.registry_write()
    mitmdump_process.stop()

if __name__ == "__main__":
    pxy = ProxySetting()
    set_proxy()
    close_proxy()

在这个示例中，我们使用了subprocess模块中的Popen()函数来创建mitmdump进程对象，并将其赋值给全局变量mitmdump_process。在close_proxy()中，我们只需要调用mitmdump进程对象的stop()方法即可停止mitmdump进程。
