nodejs中获取本机ip的方法

const os = require('os')

function getNetworkIp() {
  let needHost = '' // 打开的host
  try {
    // 获得网络接口列表
    let network = os.networkInterfaces()
    // console.log("network",network)
    for (let dev in network) {
      let iface = network[dev]
      for (let i = 0; i < iface.length; i++) {
        let alias = iface[i]
        if (
          alias.family === 'IPv4' &&
          alias.address !== '127.0.0.1' &&
          !alias.internal
        ) {
          needHost = alias.address
        }
      }

  } catch (e) {
    needHost = 'localhost'
