–web服务端Node.js
const os = require(\'os\');
module.exports =
{
getLocalIP : function()
{
const eth0 = os.networkInterfaces().eth0;
let localhost = null;
for (let i = 0; i < eth0.length; i++)
{
if (eth0[i].family == \'IPv4\')
{
localhost = eth0[i].address;
}
}
return localhost;
},
};
以上这篇获取本机IP地址的实例(JavaScript / Node.js)就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
