vue项目自动获取本机局域网ip地址

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();
        for (let dev in network) {
            let iface = network[dev];
            for (let i = 0; i < iface.length; i++) {
                let alias = iface[i];
