PyHacker编写指南引用Nmap模块实现端口扫描器

pip install nmap
pip install Python-nmap

import nmap
def nmapScan(host,port):
        nmScan=nmap.PortScanner()       #实例化
        state = nmScan.scan(host,port)  #scan() 方法扫描端口
        print state
nmapScan('127.0.0.1','80')

state = nmScan.scan(host,port,arguments='-O')  #scan()

    nmScan=nmap.PortScanner()       #实例化
    nmScan.scan(host,port)  #scan() 方法扫描端口
    print nmScan.command_line() #输出命令
    print nmScan.scaninfo() #返回nmap扫描信息，为字典类型
    print nmScan.all_hosts() #返回nmap扫描信息，为列表类型

print state['scan'][host]['tcp'][int(port)]['state']
