Python 编写的自动验证端口的脚本

以下是一个使用 Python 编写的自动验证端口的脚本示例：

import socket

def connection_host(host, port):
    cli = socket.socket(family=socket.AF_INET, type=socket.SOCK_STREAM)
    cli.settimeout(1)
    try:
        cli.connect((host, int(port)))
        cli.close()
        #print(host + ":" + str(port) + " success!!")
    except Exception as e:
        print("检测不通过======")
        print(host + ":" + str(port))

    # except socket.timeout as scto:
    #     """
    #     处理主机不通
    #    """
    #     print(host + ":" + str(port) + scto)

def read_file_tocheck():
    with open('host_port.txt','r') as f:
        lines = f.readlines()
        for line in lines:
            data = line.split(":",1)
            host = data[0]
            port = data[1]
            connection_host(host,port)

新建host_port.txt文件，文件内容示例：
127.0.0.1:8080
127.0.0.1:8090
然后执行即可，这样可以快速批量检查端口网络策略是否通。
