莱恩，谢谢你给我指明了方向。我用一些代码充实了你的答案(第二段)，它是有效的。在这个场景中，这些代码片段被放在我的express应用程序中:

// set up plain http server
var http = express();

// set up a route to redirect http to https
http.get('*', function(req, res) {  
    res.redirect('https://' + req.headers.host + req.url);

    // Or, if you don't want to automatically detect the domain name from the request header, you can hard code it:
    // res.redirect('https://example.com' + req.url);
})

// have it listen on 8080
http.listen(8080);

https express服务器监听3000上的ATM。我设置了这些iptables规则，这样节点就不必以root用户运行:

iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 3000

总的来说，这和我想要的完全一样。

为了防止通过HTTP窃取cookie，请参阅以下答案(来自评论)或使用以下代码:

const session = require('cookie-session');
app.use(
  session({
    secret: "some secret",
    httpOnly: true,  // Don't let browser javascript access cookies.
    secure: true, // Only use cookies over https.
  })
);

这个脚本在加载页面时保存URL页面，并检查地址是https还是http。如果是http，脚本会自动将您重定向到相同的https页面

(function(){
  var link = window.location.href;
  if(link[4] != "s"){
    var clink = "";
    for (let i = 4; i < link.length; i++) {
      clink += link[i];
    }
    window.location.href = "https" + clink;
  }
})();

你可以使用“net”模块在同一个端口上监听HTTP和HTTPS

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

var net=require('net');
var handle=net.createServer().listen(8000)

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(handle);

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

如果安全，请求通过https，否则重定向到https

app.enable('trust proxy')
app.use((req, res, next) => {
    req.secure ? next() : res.redirect('https://' + req.headers.host + req.url)
})

这招对我很管用:

/* Headers */
require('./security/Headers/HeadersOptions').Headers(app);

/* Server */
const ssl = {
    key: fs.readFileSync('security/ssl/cert.key'),
    cert: fs.readFileSync('security/ssl/cert.pem')
};
//https server
https.createServer(ssl, app).listen(443, '192.168.1.2' && 443, '127.0.0.1');
//http server
app.listen(80, '192.168.1.2' && 80, '127.0.0.1');
app.use(function(req, res, next) {
    if(req.secure){
        next();
    }else{
        res.redirect('https://' + req.headers.host + req.url);
    }
});

建议在重定向到https之前添加头

现在，当你这样做时:

curl http://127.0.0.1 --include

你会得到:

HTTP/1.1 302 Found
//
Location: https://127.0.0.1/
Vary: Accept
Content-Type: text/plain; charset=utf-8
Content-Length: 40
Date: Thu, 04 Jul 2019 09:57:34 GMT
Connection: keep-alive

Found. Redirecting to https://127.0.0.1/

我使用快捷4.17.1

我找到了req。协议工作时，我使用express(没有测试，但我怀疑它工作)。使用当前节点0.10.22和express 3.4.3

app.use(function(req,res,next) {
  if (!/https/.test(req.protocol)){
     res.redirect("https://" + req.headers.host + req.url);
  } else {
     return next();
  } 
});
