启动并支持 http/https 方法

简述：开启 3001-http，3002-https，2 个端口的服务，创建 3000-net 服务将传过来的 tcp/ip ，服务分发给 http/https，分发判断逻辑是传过来的是什么协议就分发给那个协议的服务上

1. 获取.key.pem nginx 证书（略阿里云上申请/下载）

2. 将证书放在项目中并引入

   var https = require("https");
   var fs = require("fs");
   // *同步读取密钥和签名证书
   var options = {
     key: fs.readFileSync(__dirname + "/key.key"),
     cert: fs.readFileSync(__dirname + "/pem.pem"),
   };
   

3. 创建 https 服务

   var httpsServer = https.createServer(options, app);
   httpsServer.listen(3002);
   

4. 开启 net 服务

   net 服务介绍

   // 2、创建服务器进行代理
   net
     .createServer(function (socket) {
       socket.once("data", function (buf) {
         // console.log(buf[0]);
         // https 数据流的第一位是十六进制“16”，转换成十进制就是 22
         var address = buf[0] === 22 ? httpsPort : httpPort;
         //创建一个指向 https 或 http 服务器的链接
         var proxy = net.createConnection(address, function () {
           proxy.write(buf);
           //反向代理的过程，tcp 接受的数据交给代理链接，代理链接服务器端返回数据交由 socket 返回给客户端
           socket.pipe(proxy).pipe(socket);
         });
         proxy.on("error", function (err) {
           console.log(err);
         });
       });
       socket.on("error", function (err) {
         console.log(err);
       });
     }, app)
     .listen(3003); // 执行函数 此处是真正能够访问的端口，网站默认是 80 端口。
