获取本地的IP地址
Windows下2种方法:
1.
使用拨号上网的话,一般都有一个本地ip和一个外网ip,使用python可以很容易的得到这两个ip
使用gethostbyname和gethostbyname_ex两个函数可以实现
- import socket
- localIP = socket.gethostbyname(socket.gethostname())#得到本地ip
- print "local ip:%s "%localIP
- ipList = socket.gethostbyname_ex(socket.gethostname())
- for i in ipList:
- if i != localIP:
- print "external IP:%s"%i
复制代码 2.
- import socket
- myname = socket.getfqdn(socket.gethostname())
- myaddr = socket.gethostbyname(myname)
复制代码 还有一种Linux下的方法可以用的是:
Uses the Linux SIOCGIFADDR ioctl to find the IP address associated with a network interface, given the name of that interface, e.g. "eth0". The address is returned as a string containing a dotted quad.
- import socket
- import fcntl
- import struct
- def get_ip_address(ifname):
- s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
- return socket.inet_ntoa(fcntl.ioctl(
- s.fileno(),
- 0x8915, # SIOCGIFADDR
- struct.pack('256s', ifname[:15])
- )[20:24])
-
复制代码 >>> get_ip_address('lo')
'127.0.0.1'
>>> get_ip_address('eth0')
'38.113.228.130'
Java版本:- private Set getAllLocalHostIP() throws UnknownHostException{
- Set result = new HashSet();
- InetAddress addr = InetAddress.getLocalHost();
- String hostName = addr.getHostName();
- if(hostName.length() > 0){
- InetAddress[] addrs = InetAddress.getAllByName(hostName);
- if(addrs.length > 0){
- for(int i=0; i<addrs.length; i++){
- result.add(addrs[i].getHostAddress());
- }
- }
- }
-
- result.add("127.0.0.1");
- return result;
- }
