如何使用Express在端口443上侦听？

Question

var app, certificate, credentials, express, fs, http, httpServer, https, httpsServer, privateKey;

fs = require('fs');

http = require('http');

https = require('https');

privateKey = fs.readFileSync('key.pem', 'utf8');

console.log(privateKey);

certificate = fs.readFileSync('cert.pem', 'utf8');

console.log(certificate);

credentials = {
  key: privateKey,
  cert: certificate
};

express = require('express');

app = express();

httpServer = http.createServer(app);

httpsServer = https.createServer(credentials, app);

httpServer.listen(80);

httpsServer.listen(443);

I am on OS X and I have confirmed nothing else is listening on 80 and 443. I run this as sudo and when I go http://127.0.0.1 , it works. However, when I go to https://127.0.0.1 , I get not found.

What am I doing incorrect?

Answer 1

add the following line of code:

app.listen(443);

Also, try getting rid of all of the http module, as express handles most of that for you. Look at the beginning Hello World for Express, http://expressjs.com/starter/hello-world.html and look for the part where it handles the port.

Answer 2

To enable your app to listen for both http and https on ports 80 and 443 respectively, do the following

Create an express app:

var express = require('express');
var app = express();

The app returned by express() is a JavaScript function. It can be be passed to Node's HTTP servers as a callback to handle requests. This makes it easy to provide both HTTP and HTTPS versions of your app using the same code base.

You can do so as follows:

var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');
var app = express();

var options = {
  key: fs.readFileSync('/path/to/key.pem'),
  cert: fs.readFileSync('/path/to/cert.pem')
};

http.createServer(app).listen(80);
https.createServer(options, app).listen(443);
