node 获取本机ip地址

方法一:
 node 14之前的
require('os').networkInterfaces()[Object.keys(require('os').networkInterfaces())[0]][1].address + ':8080' 

vue.config.js

module.exports = {
  lintOnSave: false, // 是否开启eslint保存检测,有效值:ture | false | 'error'
  publicPath: '',
  outputDir: process.env.outputDir,
  devServer: {
    public: require('os').networkInterfaces()[Object.keys(require('os').networkInterfaces())[0]][1].address + ':8080',
    disableHostCheck: true,
    open: true,
    proxy: {
      '/api': {
        target: 'http://xxx.com',
        pathRewrite: {'^/api' : ''},
        changeOrigin: true,    
        secure: false,   
      },
    }
  },
};

 

方法二:

node 14 之后的

const os = require('os');
/**
 * 获取当前机器的ip地址
 */
 function getIpAddress() {
  let ifaces = os.networkInterfaces()
  for (let dev in ifaces) {
      let iface = ifaces[dev]
      for (let i = 0; i < iface.length; i++) {
          let { family, address, internal } = iface[i]
          if (family === 'IPv4' && address !== '127.0.0.1' && !internal) {
              return address
          }
      }
  }
}

 vue.config.js

const os = require('os');
/**
 * 获取当前机器的ip地址
 */
 function getIpAddress() {
  let ifaces = os.networkInterfaces()
  for (let dev in ifaces) {
      let iface = ifaces[dev]
      for (let i = 0; i < iface.length; i++) {
          let { family, address, internal } = iface[i]
          if (family === 'IPv4' && address !== '127.0.0.1' && !internal) {
              return address
          }
      }
  }
}

module.exports = {
  lintOnSave: false, // 是否开启eslint保存检测,有效值:ture | false | 'error'
  publicPath: '',
  outputDir: process.env.outputDir,
  devServer: {
    public: getIpAddress() + ':8080',
    disableHostCheck: true,
    open: true,
    proxy: {
      '/api': {
        target: 'http://mh.885505.com',
        pathRewrite: {'^/api' : ''},
        changeOrigin: true,    
        secure: false,   
      },
    }
  },
};

 效果:

 

 注: 我之前用的是node 8、 node 12  用的第一种方法,后来升级node 14  运行时报错了 找不到 address , 方法二可以;
