express.js，我如何区分http服务器和https服务器？

Question

我想在服务器启动时在控制台中记录信息。

这样的信息：

http server is started, address: http://127.0.0.1:2223

https server is started, address: https://127.0.0.1:2222

这是我的代码：

httpsServer.on('listening', () => onListening(httpsServer));
httpServer.on('listening', () => onListening(httpServer));

function onListening(server: http.Server | https.Server) {
  const addr = server.address();
  let protocoal: string;

  //Here, I want to distinguish https and http server.
  //Is there nodeJs/express.js way rather than pass a parameter way?
  //like `server.secure` api?

  protocol = server.secure ? 'https' : 'http';

  console.log(protocoal + ' server is started，address：' + addr.address + ':' + addr.port);
}

Answer 1

Express有req.secure这是一个布尔属性，如果建立了TLS连接，则为true。
