Python获取本机所有网卡ip,掩码和广播地址实例代码
本文主要研究的是使用Python获取本机所有网卡ip,掩码和广播地址,分享了相关的实例代码,具体介绍如下。
搜了一天,竟然没找到一段合适的代码来获取机器中所有网卡的ip,掩码和广播地址,大部分都是用socket,但是socket通常返回的要不就是内网地址,要不就是公网地址,不能够找到所有地址,真的太忧桑了,决定自己通过ifconfig或ipconfig的返回信息,一步步地过滤了。这次的代码主要用到了正则表达式和subprocess模块,而且为了兼容所有平台(win,linux和mac),也用到了platform来判断系统类型,不说太多,代码如下:
importsubprocess importre importplatform deffind_all_ip(platform): ipstr='([0-9]{1,3}\.){3}[0-9]{1,3}' ifplatform=="Darwin"orplatform=="Linux": ipconfig_process=subprocess.Popen("ifconfig",stdout=subprocess.PIPE) output=ipconfig_process.stdout.read() ip_pattern=re.compile('(inet%s)'%ipstr) ifplatform=="Linux": ip_pattern=re.compile('(inetaddr:%s)'%ipstr) pattern=re.compile(ipstr) iplist=[] foripaddrinre.finditer(ip_pattern,str(output)): ip=pattern.search(ipaddr.group()) ifip.group()!="127.0.0.1": iplist.append(ip.group()) returniplist elifplatform=="Windows": ipconfig_process=subprocess.Popen("ipconfig",stdout=subprocess.PIPE) output=ipconfig_process.stdout.read() ip_pattern=re.compile("IPv4Address(\.)*:%s"%ipstr) pattern=re.compile(ipstr) iplist=[] foripaddrinre.finditer(ip_pattern,str(output)): ip=pattern.search(ipaddr.group()) ifip.group()!="127.0.0.1": iplist.append(ip.group()) returniplist deffind_all_mask(platform): ipstr='([0-9]{1,3}\.){3}[0-9]{1,3}' maskstr='0x([0-9a-f]{8})' ifplatform=="Darwin"orplatform=="Linux": ipconfig_process=subprocess.Popen("ifconfig",stdout=subprocess.PIPE) output=ipconfig_process.stdout.read() mask_pattern=re.compile('(netmask%s)'%maskstr) pattern=re.compile(maskstr) ifplatform=="Linux": mask_pattern=re.compile(r'Mask:%s'%ipstr) pattern=re.compile(ipstr) masklist=[] formaskaddrinmask_pattern.finditer(str(output)): mask=pattern.search(maskaddr.group()) ifmask.group()!='0xff000000'andmask.group()!='255.0.0.0': masklist.append(mask.group()) returnmasklist elifplatform=="Windows": ipconfig_process=subprocess.Popen("ipconfig",stdout=subprocess.PIPE) output=ipconfig_process.stdout.read() mask_pattern=re.compile(r"SubnetMask(\.)*:%s"%ipstr) pattern=re.compile(ipstr) masklist=[] formaskaddrinmask_pattern.finditer(str(output)): mask=pattern.search(maskaddr.group()) ifmask.group()!='255.0.0.0': masklist.append(mask.group()) returnmasklist defget_broad_addr(ipstr,maskstr): iptokens=map(int,ipstr.split(".")) masktokens=map(int,maskstr.split(".")) broadlist=[] foriinrange(len(iptokens)): ip=iptokens[i] mask=masktokens[i] broad=ip&mask|(~mask&255) broadlist.append(broad) return'.'.join(map(str,broadlist)) deffind_all_broad(platform): ipstr='([0-9]{1,3}\.){3}[0-9]{1,3}' ifplatform=="Darwin"orplatform=="Linux": ipconfig_process=subprocess.Popen("ifconfig",stdout=subprocess.PIPE) output=(ipconfig_process.stdout.read()) broad_pattern=re.compile('(broadcast%s)'%ipstr) ifplatform=="Linux": broad_pattern=re.compile(r'Bcast:%s'%ipstr) pattern=re.compile(ipstr) broadlist=[] forbroadaddrinbroad_pattern.finditer(str(output)): broad=pattern.search(broadaddr.group()) broadlist.append(broad.group()) returnbroadlist elifplatform=="Windows": iplist=find_all_ip(platform) masklist=find_all_mask(platform) broadlist=[] foriinrange(len(iplist)): broadlist.append(get_broad_addr(iplist[i],masklist[i])) returnbroadlist system=platform.system() print(find_all_ip(system)) print(find_all_mask(system)) print(find_all_broad(system))
