在谷歌搜索“节点https”时发现了这个问题，但接受的答案中的示例非常旧——取自当前(v0.10)版本的节点文档，它应该是这样的:

var https = require('https');
var fs = require('fs');

var options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.pem')
};

https.createServer(options, function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}).listen(8000);

对于Node 0.3.4及以上版本，一直到当前的LTS(在此编辑时为v16)， https://nodejs.org/api/https.html#httpscreateserveroptions-requestlistener有您需要的所有示例代码:

const https = require(`https`);
const fs = require(`fs`);

const options = {
  key: fs.readFileSync(`test/fixtures/keys/agent2-key.pem`),
  cert: fs.readFileSync(`test/fixtures/keys/agent2-cert.pem`)
};

https.createServer(options, (req, res) => {
  res.writeHead(200);
  res.end(`hello world\n`);
}).listen(8000);

请注意，如果想使用certbot工具使用Let's Encrypt的证书，则私钥称为privkey。Pem，证书名为fullchain.pem:

const certDir = `/etc/letsencrypt/live`;
const domain = `YourDomainName`;
const options = {
  key: fs.readFileSync(`${certDir}/${domain}/privkey.pem`),
  cert: fs.readFileSync(`${certDir}/${domain}/fullchain.pem`)
};

在Node.js中HTTPS服务器的最小设置是这样的:

var https = require('https');
var fs = require('fs');

var httpsOptions = {
    key: fs.readFileSync('path/to/server-key.pem'),
    cert: fs.readFileSync('path/to/server-crt.pem')
};

var app = function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}

https.createServer(httpsOptions, app).listen(4433);

如果你也想支持http请求，你需要做一个小小的修改:

var http = require('http');
var https = require('https');
var fs = require('fs');

var httpsOptions = {
    key: fs.readFileSync('path/to/server-key.pem'),
    cert: fs.readFileSync('path/to/server-crt.pem')
};

var app = function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}

http.createServer(app).listen(8888);
https.createServer(httpsOptions, app).listen(4433);

要让你的应用程序分别在端口80和443上监听http和https，请执行以下操作

创建一个express应用程序:

var express = require('express');
var app = express();

express()返回的应用程序是一个JavaScript函数。它可以作为回调传递给Node的HTTP服务器来处理请求。这使得使用相同的代码库提供HTTP和HTTPS版本的应用程序变得很容易。

你可以这样做:

var express = require('express');
var https = require('https');
var http = require('http');
var fs = require('fs');
var app = express();

var options = {
  key: fs.readFileSync('/path/to/key.pem'),
  cert: fs.readFileSync('/path/to/cert.pem')
};

http.createServer(app).listen(80);
https.createServer(options, app).listen(443);

要获得完整的细节，请参阅文档

上面的答案很好，但是对于Express和node，这将工作得很好。

由于express为您创建了应用程序，我将跳过这里。

var express = require('express')
  , fs = require('fs')
  , routes = require('./routes');

var privateKey = fs.readFileSync('cert/key.pem').toString();
var certificate = fs.readFileSync('cert/certificate.pem').toString();  

// To enable HTTPS
var app = module.exports = express.createServer({key: privateKey, cert: certificate});
