使用python进行端口扫描

import socket

def scan_port(host, port):
    try:
        # 创建socket对象
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        # 设置超时时间
        s.settimeout(1)
        # 尝试连接目标主机的指定端口
        result = s.connect_ex((host, port))
        if result == 0:
            print(f"Port {port} is open")
        else:
            print(f"Port {port} is closed")
        # 关闭socket连接
        s.close()
    except socket.error:
        print("Error occurred while scanning port")

# 调用端口扫描函数
scan_port("127.0.0.1", 80)
