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());
