nodejs获取本地IP地址

	//查看本地IP地址
			getLocalIP() {
				
				const os = require('os');
				const osType = os.type(); //系统类型
				const ifaces = os.networkInterfaces(); //网络信息
				let locatIp = '';
				for (let dev in ifaces) {
					//console.log(dev)   //打印看结果
					if (dev === '本地连接' || dev === 'WLAN') {
						for (let j = 0; j < ifaces[dev].length; j++) {
							if (ifaces[dev][j].family === 'IPv4') {
								locatIp = ifaces[dev][j].address;
								break;
							}
						}
					}
				}
			console.log(osType) 
			console.log(locatIp)  //IP地址
			return locatIp;
