前端js如何獲取本機ip

獲取方式：

function getIPAdress() {
  var interfaces = require('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) {
        return alias.address;
      }
    }
  }
}

使用方式：

module.exports = {
  dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    // 代理列表, 是否開啟代理通過[./dev.env.js]配置
    proxyTable: devEnv.OPEN_PROXY === false ? {} : {
      '/proxyApi': {
        target: 'http://demo.renren.io/renren-fast/',
        changeOrigin: true,
        pathRewrite: {
          '^/proxyApi': '/'
        }
      }
    },

    // Various Dev Server settings
    host: getIPAdress(), // can be overwritten by process.env.HOST
    // host: 'localhost', // can be overwritten by process.env.HOST
    port: 5286, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
    autoOpenBrowser: false,
    errorOverlay: true,
    notifyOnErrors: true,
    poll: false, // https://webpack

這樣避免直接填寫ip導致多人開發報錯問題
