1.生成证书文件

//生成私钥key文件:

openssl genrsa 1024 > /文件路径/private.pem

//通过私钥文件生成CSR证书签名：

openssl req -new -key /文件路径/private.pem -out /文件路径/csr.pem

//通过私钥文件和CSR证书签名生成证书文件：

openssl x509 -req -days 365 -in /文件路径/csr.pem -signkey /文件路径/private.pem -out /文件路径/file.crt

2.导入fs文件操作模块

npm install fs --save

3.修改启动文件./bin/www

#!/usr/bin/env node

/**
 * Module dependencies.
 */

var app = require('../app');
var debug = require('debug')('chat-s:server');
var http = require('http');
var https = require('https');
var fs = require('fs');

/**
 * 设置https证书和私钥key
 */
var options = {
  key: fs.readFileSync('/文件路径/private.pem'),
  cert: fs.readFileSync('/文件路径/file.crt')
};

/**
 * Get port from environment and store in Express.
 */

var port = normalizePort(process.env.PORT || '8080');
app.set('port', port);

/**
 * Create HTTP server.
 */
//注释http服务的创建，修改为https服务
// var server = http.createServer(app);
var server = https.createServer(options,app);

/**
 * Listen on provided port, on all network interfaces.
 */

server.listen(port);
server.on('error', onError);
server.on('listening', onListening);

/**
 * Normalize a port into a number, string, or false.
 */

function normalizePort(val) {
  var port = parseInt(val, 10);

  if (isNaN(port)) {
    // named pipe
    return val;
  }

  if (port >= 0) {
    // port number
    return port;
  }

  return false;
}

/**
 * Event listener for HTTP server "error" event.
 */

function onError(error) {
  if (error.syscall !== 'listen') {
    throw error;
  }

  var bind = typeof port === 'string'
    ? 'Pipe ' + port
    : 'Port ' + port;

  // handle specific listen errors with friendly messages
  switch (error.code) {
    case 'EACCES':
      console.error(bind + ' requires elevated privileges');
      process.exit(1);
      break;
    case 'EADDRINUSE':
      console.error(bind + ' is already in use');
      process.exit(1);
      break;
    default:
      throw error;
  }
}

/**
 * Event listener for HTTP server "listening" event.
 */

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

4.node.js服务启动

npm start 

结果

因为是自己生成的证书，未经过安全验证，正式环境需要去申请
