新建js文件

getIpAddress.js

//获取本机的IP地址
function getNetworkIp() {
    let ip = 'localhost';
    try {
        const network = Os.networkInterfaces();//获取本机的网路
        for (const iter in network) {
            const faces = network[iter];
            for (const interface of faces) {
                if (interface.family === 'IPv4' && interface.address !== '127.0.0.1' && !interface.internal) {
                    ip = interface.address;
                    return ip;
                }
            }
        }
    } catch (e) {

    }
    return ip;
}
module.exports = getNetworkIp;

在index.js文件中添加以下配置

dev: {

    // Paths
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {},

    // Various Dev Server settings
    host: getNetworkIp(), // can be overwritten by process.env.HOST
    useLocalIp: true,//允许使用本地IP地址进行访问
    port: 18880, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
