express 本地https服务 接口、静态文件，并支持跨域

var express = require('express');
var app = express();
//设置跨域访问
app.all('*', function (req, res, next) {res.header('Access-Control-Allow-Origin', '*');res.header('Access-Control-Allow-Credentials', true);res.header('Access-Control-Allow-Headers', 'Content-Type,Content-Length, Authorization, Accept,X-Requested-With')res.header('Access-Control-Allow-Methods', 'PUT,POST,GET,DELETE,OPTIONS');//res.header('Content-Type', 'application/json;charset=utf-8');next()
});// 当路由url匹配为'/'时，执行function，返回Hello World
app.get('/', function (req, res) {res.send('Hello World');
});app.use('/publicStaticPath',express.static("./dist"));
// 访问 https://localhost:6789/publicStaticPath/文件名 ，可以获取相应静态文件app.listen(6788,()=>console.log('http://localhost:6788'));// HTTPS
var fs = require('fs');
//同步读取密钥和签名证书
const options = {key:fs.readFileSync('./cert/cert-key.pem'),cert:fs.readFileSync('./cert/cert.pem')
}
// 创建https server的时候 传入服务器私钥和服务器证书
// 引入https模块
var https = require('https');
var httpsServer = https.createServer(options,app);
//https监听8080端口
httpsServer.listen(6789,()=>console.log('https://localhost:6789'));
