python最简洁易懂的扫描端口代码.运行绝对会很有惊奇感

复制代码 代码如下:
from threading import Thread, activeCount

import socket

import os

def test_port(dst,port):

    os.system('title '+str(port))

    cli_sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

    try:

        indicator = cli_sock.connect_ex((dst, port))

        if indicator == 0:

            print(port)

        cli_sock.close()

    except:

        pass

if __name__=='__main__':

    dst = '192.168.0.22'

    i = 0

    while i < 65536:

        if activeCount() <= 200:

            Thread(target = test_port, args = (dst, i)).start()

            i = i + 1

    while True:

        if activeCount() == 2:

            break

    input('Finished scanning.')
