How to configure SSL for koa2 service

I. Introduction

1: SSL Certificate

My domain name is in Tencent Cloud. Every time I create a third-level domain name (assuming it is aaa.jiangw1.com), I will be given a one-year SSL. After the application is successful, I can download the SSL certificate as follows:

You can see that various server files are prepared. The common SSL file in the red circle can be used for the node service.

2: Analysis

aaa.jiangw1.com: Fill in A for record type and server public IP for record value

Two: Code

The following code is limited to the koa2 project, and other node projects are similar.

1: Install dependencies

npm install koa-sslify
npm install koa2-cors

2: app.js added

const app = new Koa();
const cors = require('koa2-cors');
const sslify = require('koa-sslify').default;

// Use SSL
app.use(sslify());

// Cross-domain settings app.use(cors({
  origin: function (ctx) {
    return ctx.header.origin;
  }
}))

3: bin folder modification

Create a new ssl folder and put the .key and .pem files in the SSL certificate.

Modify bin/www as follows:

var https = require("https");
var fs = require("fs");
var path = require("path");
/**
 * Create HTTP server.
 */
// SSL options
var options = {
  key: fs.readFileSync(path.join(__dirname, './ssl/aaa.jiangw1.com.key')),
  cert: fs.readFileSync(path.join(__dirname, './ssl/aaa.jiangw1.com.pem'))
};
// var server = http.createServer(app.callback());
var httpsServer = https.createServer(options, app.callback());
httpsServer.listen(port, (err) => {
  if (err) {
    console.log('server init error', err);
  } else {
    console.log('server running at port :' + port);
  }
});
httpsServer.on('error', onError);
httpsServer.on('listening', onListening);
/**
 * Event listener for HTTP server "listening" events.
 */
function onListening() {
  // var addr = server.address();
  var addr = httpsServer.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
}

4: Start

Local startup:
Open the browser and go to https://localhost:3010. If you can get in, it means the local configuration is successful. You should be prompted that the domain name is invalid.
Server startup:
After uploading the source code, start the service with pm2 and access aaa.jiangw1.com with your browser. If you can access it, it means the local configuration is successful.

Three: Notes

• Linux server needs to open port 443
• The ssl certificate file must be configured accurately
• The port of the node service must be exposed
• Domain name resolution must be filled in accurately
