Node.js Express端口监听两种方式

Node.js使用Express时，对端口对监听有两种方式，笔记如下：

只使用Express端口监听方式

const express = require('express')
const app = express()
var server = app.listen(8080)
app.get('/', function (req, res) {
   console.log("GET Reqest");
   res.send('Hello GET');
})

Express和原生http/https共生方式

const http = require('http')
const https = require('https')
const fs = require('fs')

const express = require('express')
const app = express()

var server = http.createServer(app).listen(8080)

const options = {
  key: fs.readFileSync('./key.pem'),
  cert: fs.readFileSync('./key-cert.pem')
};
var sserver = https.createServer(options, app).listen(443)

app.get('/', function (req, res) {
   console.log("Express GET Reqest");
   res.send('Hello GET');
})

server.on("request",function(req,res){
    console.log("hello http")
});

sserver.on("request",function(req,res){
    console.log("hello https");

});

其中参考key.pem内容如下，放置于工程根目录下：

-----BEGIN RSA PRIVATE KEY-----

而参考key-cert.pem内容如下，放在工程根目录：
