electron中获取mac地址

引入
为了方便做单点登录，我们往往需要使用某个唯一标识来标记客户端的设备，mac地址就是一个还不错的选择

思路

我们可以使用Node.js的内置模块os，调用其中的networkInterfaces方法。该方法会返回一个包含网络接口信息的数组对象，通过遍历该数组对象，可以获取到Mac地址，我们先看下调用得到的响应内容

import { networkInterfaces } from "os";
console.log(JSON.stringify(networkInterfaces()));

 

{"Ethernet0": [{"address": "fe80::803c:6a7b:14b0:f652","netmask": "ffff:ffff:ffff:ffff::","family": "IPv6","mac": "00:0c:29:ea:41:55","internal": false,"cidr": "fe80::803c:6a7b:14b0:f652/64","scopeid": 7}, {"address": "192.168.213.154","netmask": "255.255.255.0","family": "IPv4","mac": "00:0c:29:ea:41:55","internal": false,"cidr": "192.168.213.154/24"}],"Loopback Pseudo-Interface 1": [{"address": "::1","netmask": "ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff","family": "IPv6","mac": "00:00:00:00:00:00","internal": true,"cidr": "::1/128","scopeid": 0}, {"address": "127.0.0.1","netmask": "255.0.0.0","family": "IPv4","mac": "00:00:00:00:00:00","internal": true,"cidr": "127.0.0.1/8"}]
}

封装代码

可以看到是个键值对的形式，所以我们直接获取key，然后遍历取值，再获取对象中的mac地址即可：

/**获取mac地址信息 */
export const getMacAddress = function (): string {const interfaces = networkInterfaces();let macAddress = "";for (const interfaceName of Object.keys(interfaces)) {const interfaceInfos = interfaces[interfaceName];if (interfaceInfos) {for (const interfaceInfo of interfaceInfos) {if (interfaceInfo.mac && interfaceInfo.mac !== "00:00:00:00:00:00") {macAddress = interfaceInfo.mac;break;}}}if (macAddress.length > 0) break;}return macAddress;
};
