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});

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);

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);

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);

更新

通过Greenlock.js使用Let's Encrypt

最初的发布

我注意到，这些答案都没有显示添加一个中间根CA到链中，这里有一些零配置的例子来看看:

https://github.com/solderjs/nodejs-ssl-example http://coolaj86.com/articles/how-to-create-a-csr-for-https-tls-ssl-rsa-pems/ https://github.com/solderjs/nodejs-self-signed-certificate-example

代码片段:

var options = {
  // this is the private key only
  key: fs.readFileSync(path.join('certs', 'my-server.key.pem'))

// this must be the fullchain (cert + intermediates)
, cert: fs.readFileSync(path.join('certs', 'my-server.crt.pem'))

// this stuff is generally only for peer certificates
//, ca: [ fs.readFileSync(path.join('certs', 'my-root-ca.crt.pem'))]
//, requestCert: false
};

var server = https.createServer(options);
var app = require('./my-express-or-connect-app').create(server);
server.on('request', app);
server.listen(443, function () {
  console.log("Listening on " + server.address().address + ":" + server.address().port);
});

var insecureServer = http.createServer();
server.listen(80, function () {
  console.log("Listening on " + server.address().address + ":" + server.address().port);
});

如果你不尝试直接通过connect或express来做，这是那些通常更容易的事情之一，而是让本地https模块处理它，然后使用它来为你的connect / express应用服务。

另外，如果你使用服务器。On ('request'， app)而不是在创建服务器时传递应用程序，它让你有机会将服务器实例传递给一些创建connect / express应用程序的初始化函数(例如，如果你想在同一台服务器上通过SSL进行websockets)。
