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;
- };
