How to test HTTPS locally with Express

This time I will show you how Express tests HTTPS locally, and what are the precautions for Express to test HTTPS locally. The following is a practical case, let's take a look.

My environment

1. An ubuntu virtual machine on Amazon (AWS).

2. node

3. openssl

##Generate certificate

Enter the following command to generate localhost.key and localhost.cert in your current folder.

openssl genrsa -out localhost.key 2048
openssl req -new -x509 -key localhost.key -out localhost.cert -days 3650 -subj /CN=localhost

where localhost is the domain name. If you want to change it to another domain name, just replace all localhost above with yours Domain name.

Take me as an example. The domain name of my virtual machine is

xxx.compute.amazonaws.com. Just replace all the localhosts above with this domain name and it will generate, ec2-34-220-96-9.us-west-2.compute.amazonaws.com.key and ec2-34-220-96-9.us-west-2.compute.amazonaws. com.certTwo files.

Update

openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365

If you don’t want to protect the private key with a password, add

-nodes.

Add You can set the certificate content on

-subj '/CN=localhost'. Replace localhost with your domain name.

Code

If you want to run the following code, you need to install the package first

npm init
npm i -S https express

Create the file index.js, the content is as follows.

#!/usr/bin/env node
var https = require('https');
var fs = require('fs');
var express = require('express');
var host = 'xxx.compute.amazonaws.com'; // Input you domain name here.
var options = {
  key: fs.readFileSync( './' + host + '.key' ),
  cert: fs.readFileSync( './' + host + '.cert' ),
  requestCert: false,
  rejectUnauthorized: false
};
var httpApp = express();
var app = express();
app.get('/', function (req, res) {
 res.send('hi HTTPS');
});
httpApp.get('/', function (req, res) {
 res.send('hi HTTP');
});
httpApp.listen(80, function () {
 console.log('http on 80');
});
var server = https.createServer( options, app );
server.listen( 443, function () {
  console.log( 'https on 443' );
} );

Start the server

sudo node index.js

Access

Enter

http in the browser ://xxx.compute.amazonaws.com/ will access the HTTP server at port 80. Display hi HTTP.

Enter

https://xxx.compute .amazonaws.com/ will access the HTTPS server on port 443, displaying hi HTTPS.
