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

TypeScript 复制代码

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

TypeScript 复制代码

{
        "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：

TypeScript 复制代码

/**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;
};
