Express API文档非常清楚地说明了这一点。

此外，这个答案给出了创建自签名证书的步骤。

我从Node.js HTTPS文档中添加了一些注释和一个片段:

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

// This line is from the Node.js HTTPS documentation.
var options = {
  key: fs.readFileSync('test/fixtures/keys/agent2-key.pem'),
  cert: fs.readFileSync('test/fixtures/keys/agent2-cert.cert')
};

// Create a service (the app object is just a callback).
var app = express();

// Create an HTTP service.
http.createServer(app).listen(80);
// Create an HTTPS service identical to the HTTP service.
https.createServer(options, app).listen(443);

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);

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});

Download rar file for openssl set up from here: https://indy.fulgan.com/SSL/openssl-0.9.8r-i386-win32-rev2.zip Just copy your folder in c drive. Create openssl.cnf file and download their content from : http://web.mit.edu/crypto/openssl.cnf openssl.cnf can be put any where but path shoud be correct when we give in command prompt. Open command propmt and set openssl.cnf path C:\set OPENSSL_CONF=d:/openssl.cnf 5.Run this in cmd : C:\openssl-0.9.8r-i386-win32-rev2>openssl.exe Then Run OpenSSL> genrsa -des3 -out server.enc.key 1024 Then it will ask for pass phrases : enter 4 to 11 character as your password for certificate Then run this Openssl>req -new -key server.enc.key -out server.csr Then it will ask for some details like country code state name etc. fill it freely. 10 . Then Run Openssl > rsa -in server.enc.key -out server.key Run this OpenSSL> x509 -req -days 365 -in server.csr -signkey server.key -out server.crt then use previous code that are on stack overflow Thanks

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);
