在Vue中需要使用例外的线程去执行轮询的任务，这里以获取网卡信息为例。

注：这里是在Electron中使用的，可以使用Node.js实例 “child_process”，如果是纯Vue工程无法使用Node实例。 

1.创建一个renderer.js文件,放在public静态文件夹下。

这里以获取网卡信息为例：

// This file is required by the index.html file and will
// be executed in the renderer process for that window.
// No Node.js APIs are available in this process because
// `nodeIntegration` is turned off. Use `preload.js` to
// selectively enable features needed in the rendering
// process.var cluster = require('child_process')setInterval(() => {cluster.exec("cmd /c chcp 65001>nul && netsh wlan show interface",  (err, res) => {var node_nics = require("os").networkInterfaces();var lines = res.split('\r\n');var fields = ['name','model','vendor','mac_address','status','ssid','bssid','mode','radio','authentication','encryption','connection','channel','reception','transmission','signal','profil'];var connections = [];var tmp = {}var len = 0;for (var i = 3; i < lines.length; i++) {if (lines[i] != "" && lines[i] != null && lines[i].indexOf(":") != -1) {tmp[fields[len]] = lines[i].split(':')[1].trim()len += 1;} else {if (tmp['name'] != null && tmp['model'] != null && tmp['vendor'] != null && tmp['mac_address'] != null && tmp['status'] != null) {var node_nic = node_nics[tmp.name] || [];node_nic.forEach(function (type) {if (type.family == 'IPv4') {tmp.ip_address = type.address;tmp.ip_gateway = "http://"+type.address.split('.')[0] + "." + type.address.split('.')[1] + "." + type.address.split('.')[2] + ".1"}});connections.push(tmp);tmp = {}len = 0;}}}console.log(connections)self.postMessage(connections);})
}, 2000)

2.home.vue

var worker = new Worker("/renderer.js");
export default { name: "home",data() {return {lists: ""}},created(){var that = this;worker.onmessage = function(event) {this.lists = event.data;}},
}
