All right，The problem has fixed done：

const fs = require('fs');   //add
const options = {  //add
    key: fs.readFileSync('path/to/key.pem'), //add
    cert: fs.readFileSync('path/to/cert.pem') //add
  }; /add
const http = require('https').createServer(options,app) //change`http -> https` and add `options`
