node的express框架

var express = require('express'),
app = express(),
path = require('path'),
os = require('os'),
port = 3002;
var htmlPath = path.join(__dirname, "public");
app.use(express.static(htmlPath));

//==============启动服务==================
app.listen(port, function () {
//console.log("Example app listening on port " + port);
console.log("native browse: http://localhost:" + port);
console.log("ip browse: http://" + getLocalIP() + ":" + port);
});
// console.log(os.networkInterfaces());
function getLocalIP() { //获取IP地址
const WLAN = ((os.networkInterfaces()).WLAN)[1];
return WLAN.address;
}
