实现代码：
复制代码代码如下:
var os = require('os');
function getLocalIP() {
var map = [];
var ifaces = os.networkInterfaces();
console.log(ifaces);
for (var dev in ifaces) {
if (dev.indexOf('eth0') != -1) {
var tokens = dev.split(':');
var dev2 = null;
if (tokens.length == 2) {
dev2 = 'eth1:' + tokens[1];
} else if (tokens.length == 1) {
dev2 = 'eth1';
}
if (null == ifaces[dev2]) {
continue;
}
// 找到eth0和eth1分别的ip
var ip = null, ip2 = null;
ifaces[dev].forEach(function(details) {
if (details.family == 'IPv4') {
ip = details.address;
}
});
ifaces[dev2].forEach(function(details) {
if (details.family == 'IPv4') {
ip2 = details.address;
}
});
if (null == ip || null == ip2) {
continue;
}
// 将记录添加到map中去
if (ip.indexOf('10.') == 0 ||
ip.indexOf('172.') == 0 ||
ip.indexOf('192.') == 0) {
map.push({"intranet_ip" : ip, "internet_ip" : ip2});
} else {
map.push({"intranet_ip" : ip2, "internet_ip" : ip});
}
}
}
return map;
}
console.log(getLocalIP());
