如何在Node.js中获取本地IP地址？

http://nodejs.org/api/os.html#os_os_networkinterfaces

var os = require('os');var interfaces = os.networkInterfaces();var addresses = [];for (var k in interfaces) {    for (var k2 in interfaces[k]) {        var address = interfaces[k][k2];        if (address.family === 'IPv4' && !address.internal) { addresses.push(address.address);        }    }}console.log(addresses);
