Nodejs获取本机内网ip

通过引入os模块获取系统信息

var os = require('os');var serverIP = getIPAddress();console.log('serverIP', serverIP);// 获取内网ipfunction getIPAddress() {  let IPAddress = '';  var interfaces = os.networkInterfaces();  for (var devName in interfaces) {    var iface = interfaces[devName];    for (var i = 0; i < iface.length; i++) {      var alias = iface[i];      if (alias.family === 'IPv4' && alias.address !== '127.0.0.1' && !alias.internal) {        IPAddress = alias.address;      }    }  }  return IPAddress;};
