使用Python获取正在侦听的所有PID Id和端口

import psutil

processes = psutil.process_iter()

for process in processes:
    try:
        connections = process.connections()
        for conn in connections:
            if conn.status == psutil.CONN_LISTEN:
                pid = process.pid
                port = conn.laddr.port
                print("PID: {}, Port: {}".format(pid, port))
    except psutil.AccessDenied:
        pass
