koa2服务配置SSL的实现方法

npm install koa-sslify
npm install koa2-cors

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

// 使用 ssl
app.use(sslify());

// 跨域设置
app.use(cors({
  origin: function (ctx) {
    return ctx.header.origin;
  }
}))

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" event.
 */
function onListening() {
  // var addr = server.address();
  var addr = httpsServer.address();
  var bind = typeof addr === 'string'
    ? 'pipe ' + addr
    : 'port ' + addr.port;
  debug('Listening on ' + bind);
}
