import { networkInterfaces } from 'os';
function getLocalAddress() {
const netInfo = networkInterfaces();
let localAddress = {};
for ( let niName in netInfo ) {
netInfo[niName].forEach(( ni ) => {
if ( ni.family === 'IPv4' && ni.internal === false ) {
localAddress[niName] = ni.address;
}
});
}
return localAddress;
}
console.log(getLocalAddress());

首先通过 os 模块获取网络信息，如下：
1
| import { networkInterfaces } from 'os';
|
其中，netInfo 的内容大致如下：

"netmask": "ffff:ffff:ffff:ffff::",
"family": "IPv6",

},
{
"address": "192.168.1.30",
"netmask": "255.255.0.0",
"family": "IPv4",
"mac": "ac:1e:cb:4b:07:e3",
"internal": false,
"cidr": "192.168.1.30/16"
}

根据如上的内容，可以写一个提取内网本机的 IPv4 地址的函数：

function getLocalAddress() {
const netInfo = networkInterfaces();
let localAddress = {};
for ( let niName in netInfo ) {
netInfo[niName].forEach(( ni ) => {
if ( ni.family === 'IPv4' && ni.internal === false ) {
localAddress[niName] = ni.address;
}
});
}
return localAddress;
}
|
如果需要获取本机的 IPv6 地址，把如上函数的第 12 行的 IPv4 改成 IPv6 即可。
