为了实现在手机上访问PWA应用开发预览，需要搭建一个https服务

这里主要是实施了两个步骤
第一个：搭建https服务
第二个：转发https到本地http服务

利用openssl创建私钥和证书

1. 生成私钥：

   openssl genpkey -algorithm RSA -out key.pem
   

2. 使用生成的私钥生成自签名证书：

   openssl req -new -key key.pem -x509 -out cert.pem
   

这两个命令将生成私钥和相应的自签名证书，以便你可以将它们用于 HTTPS 服务器或其他安全通信需求。

利用nodejs创建一个https服务

  const https = require("https");
  const fs = require("fs");
  const os = require("os");
  const privateKeyPath = "key.pem";
  const certificatePath = "cert.pem";

  const privateKey = fs.readFileSync(privateKeyPath, "utf8");
  const certificate = fs.readFileSync(certificatePath, "utf8");
  const credentials = { key: privateKey, cert: certificate };

  // 获取网络接口信息
  const networkInterfaces = os.networkInterfaces();
  let ip = "";
  // 遍历网络接口并找到局域网IP地址
  for (const interfaceName in networkInterfaces) {
    const interfaces = networkInterfaces[interfaceName];
    for (const iface of interfaces) {
      if (iface.family === "IPv4" && !iface.internal) {
        ip = iface.address;
      }
    }
  }

  const httpsserver = https.createServer(credentials, (req, res) => {
    res.writeHead(200);
    res.end('Hello, HTTPS World!');
  });

  const PORT = 443; // HTTPS默认端口
  httpsserver.listen(PORT, ip, () => {
    console.log(`HTTPS服务器运行 https://${ip}`);
  });

利用第三方模块转发服务到本地dev http服务

 // 假设本地服务为8000
  const proxyTarget = `http://localhost:8000`; // 本地HTTP服务器地址
  const httpProxy = require('http-proxy');
  const proxy = httpProxy.createProxyServer({ target: proxyTarget });
  //将上文中的httpsserver内替换为下文
  const httpsserver = https.createServer(credentials, (req, res) => {
    proxy.web(req, res);
  });
