使用本教程构建了一个负载均衡器 - Building Your Own Load Balancer with ExpressJS

＆＃13;

const express = require('express');
const fs = require('fs');
const https = require('https');
const request = require('request');

const servers = ['server2', 'server1','server2'];
let cur = 0;


const profilerMiddleware = (req, res, next) => {
  const start = Date.now();
 // The 'finish' event comes from core Node.js, it means Node is done handing
  // off the response headers and body to the underlying OS.
  res.on('finish', () => {
    console.log('Completed', req.method, req.url, Date.now() - start);
  });
  next();
};


const handler = (req, res) => {
  // Add an error handler for the proxied request
  const _req = request({ url: servers[cur] + req.url }).on('error', error => {
    res.status(500).send(error.message);
  });
  req.pipe(_req).pipe(res);
  cur = (cur + 1) % servers.length;
};
const server = express().get('*', handler).post('*', handler);
server.listen(8080);

const app = express().
  // Use `express-sslify` to make sure _all_ requests use HTTPS
  use(require('express-sslify').HTTPS()).
 use(profilerMiddleware).
  get('*', handler).
  post('*', handler);

app.listen(80);

执行后，我可以从本地服务器访问https。也与服务器建立了连接，但内容未加载。每个服务器在默认端口上都有一个角度前端，在各自的IP上有一个3000端口上的节点后端。问题是所有这些都是http服务器，我想通过我的localhost加载它们作为https并且页面不加载。我为bundle.js vendor.js等文件收到404错误。任何人都可以帮我解决这个问题吗？
