从0.4.12开始，我们还没有使用Node的HTTP/HTTPS服务器在同一个端口上监听HTTP和HTTPS的真正干净的方法。

有些人通过让Node的HTTPS服务器(这也适用于Express.js)侦听443(或其他端口)，并让一个小型http服务器绑定到80并将用户重定向到安全端口来解决这个问题。

如果你必须能够在一个端口上处理这两个协议，那么你需要把nginx, lighttpd, apache，或其他一些web服务器放在那个端口上，并充当Node的反向代理。

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.
  })
);

你可以实例化2个Node.js服务器——一个用于HTTP，一个用于HTTPS

还可以定义两台服务器都将执行的设置函数，这样就不必编写大量重复的代码。

下面是我的方法:(使用retify .js，但应该适用于express.js，或node本身)

http://qugstart.com/blog/node-js/node-js-restify-server-with-both-http-and-https/

使用Nginx，你可以利用“x-forward -proto”头文件:

function ensureSec(req, res, next){
    if (req.headers["x-forwarded-proto"] === "https"){
       return next();
    }
    res.redirect("https://" + req.headers.host + req.url);  
}

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)

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();
  } 
});

这个答案需要更新以与Express 4.0一起工作。下面是我如何让单独的http服务器工作:

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

// Primary https app
var app = express()
var port = process.env.PORT || 3000;
app.set('env', 'development');
app.set('port', port);
var router = express.Router();
app.use('/', router);
// ... other routes here
var certOpts = {
    key: '/path/to/key.pem',
    cert: '/path/to/cert.pem'
};
var server = https.createServer(certOpts, app);
server.listen(port, function(){
    console.log('Express server listening to port '+port);
});


// Secondary http app
var httpApp = express();
var httpRouter = express.Router();
httpApp.use('*', httpRouter);
httpRouter.get('*', function(req, res){
    var host = req.get('Host');
    // replace the port in the host
    host = host.replace(/:\d+$/, ":"+app.get('port'));
    // determine the redirect destination
    var destination = ['https://', host, req.url].join('');
    return res.redirect(destination);
});
var httpServer = http.createServer(httpApp);
httpServer.listen(8080);

如果你遵循传统端口，因为HTTP默认尝试端口80,HTTPS默认尝试端口443，你可以简单地在同一台机器上有两个服务器: 代码如下:

var https = require('https');

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

https.createServer(options, function (req, res) {
    res.end('secure!');
}).listen(443);

// Redirect from http port 80 to https
var http = require('http');
http.createServer(function (req, res) {
    res.writeHead(301, { "Location": "https://" + req.headers['host'] + req.url });
    res.end();
}).listen(80);

使用https测试:

$ curl https://127.0.0.1 -k
secure!

与http:

$ curl http://127.0.0.1 -i
HTTP/1.1 301 Moved Permanently
Location: https://127.0.0.1/
Date: Sun, 01 Jun 2014 06:15:16 GMT
Connection: keep-alive
Transfer-Encoding: chunked

更多细节:Nodejs HTTP和HTTPS通过相同的端口

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

app.get('*',function (req, res) {
    res.redirect('https://<domain>' + req.url);
});

app.listen(80);

这就是我们所使用的，而且效果非常好!

这里的大多数答案都建议使用req.headers.host头文件。

Host报头是HTTP 1.1所要求的，但它实际上是可选的，因为报头可能不是由HTTP客户端实际发送的，node/express将接受这个请求。

你可能会问:哪个HTTP客户端(例如:浏览器)可以发送一个缺少报头的请求?HTTP协议非常简单。您可以用几行代码编写一个HTTP请求，以不发送主机标头，如果每次接收到格式错误的请求时都抛出一个异常，根据处理此类异常的方式，这可能会导致服务器宕机。

所以总是验证所有输入。这不是妄想症，我在我的服务中收到过缺少主机头的请求。

另外，永远不要把url当作字符串。使用node url模块修改字符串的特定部分。将url视为字符串可以通过许多许多方式加以利用。不要这样做。

如果你的应用程序在一个可信的代理(例如AWS ELB或正确配置的nginx)后面，这段代码应该工作:

app.enable('trust proxy');
app.use(function(req, res, next) {
    if (req.secure){
        return next();
    }
    res.redirect("https://" + req.headers.host + req.url);
});

注:

这假设您在80和443上托管站点，如果不是，则需要在重定向时更改端口 这还假定您正在终止代理上的SSL。如果你使用SSL端到端，请使用上面@basarat的答案。端到端SSL是更好的解决方案。 app.enable('trust proxy')允许express检查X-Forwarded-Proto报头

这招对我很管用:

app.use(function(req,res,next) {
    if(req.headers["x-forwarded-proto"] == "http") {
        res.redirect("https://[your url goes here]" + req.url, next);
    } else {
        return next();
    } 
});

我使用Basarat提出的解决方案，但我还需要覆盖端口，因为我曾经有2个不同的端口用于HTTP和HTTPS协议。

res.writeHead(301, { "Location": "https://" + req.headers['host'].replace(http_port,https_port) + req.url });

我也喜欢使用非标准端口，这样就可以在没有root权限的情况下启动nodejs。 我喜欢8080和8443，因为我在tomcat上编程了很多年。

我的完整文件变成

var fs = require('fs');
var http = require('http');
var http_port    =   process.env.PORT || 8080; 
var app = require('express')();

// HTTPS definitions
var https = require('https');
var https_port    =   process.env.PORT_HTTPS || 8443; 
var options = {
   key  : fs.readFileSync('server.key'),
   cert : fs.readFileSync('server.crt')
};

app.get('/', function (req, res) {
   res.send('Hello World!');
});

https.createServer(options, app).listen(https_port, function () {
   console.log('Magic happens on port ' + https_port); 
});

// Redirect from http port to https
http.createServer(function (req, res) {
    res.writeHead(301, { "Location": "https://" + req.headers['host'].replace(http_port,https_port) + req.url });
    console.log("http request, will go to >> ");
    console.log("https://" + req.headers['host'].replace(http_port,https_port) + req.url );
    res.end();
}).listen(http_port);

然后我使用iptable在我的HTTP和HTTPS端口上forword80和443流量。

sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 8080
sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8443

你可以使用express-force-https模块:

NPM install——save express-force-https

var express = require('express');
var secure = require('express-force-https');

var app = express();
app.use(secure);

感谢这个家伙: https://www.tonyerwin.com/2014/09/redirecting-http-to-https-with-nodejs.html

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

如果你的节点应用程序安装在IIS上，你可以在web.config中这样做

<configuration>
    <system.webServer>

        <!-- indicates that the hello.js file is a node.js application 
    to be handled by the iisnode module -->

        <handlers>
            <add name="iisnode" path="src/index.js" verb="*" modules="iisnode" />
        </handlers>

        <!-- use URL rewriting to redirect the entire branch of the URL namespace
    to hello.js node.js application; for example, the following URLs will 
    all be handled by hello.js:

杰克的答案更新了代码。在https服务器旁边运行这个程序。

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

var server = http.createServer(app);

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

// have it listen on 80
server.listen(80);

这对我来说是有效的:

app.get("*",(req,res,next) => {
    if (req.headers["x-forwarded-proto"]) {
        res.redirect("https://" + req.headers.host + req.url)
    }
    if (!res.headersSent) {
        next()
    }
})

把它放在所有HTTP处理程序之前。

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;
  }
})();

这个想法是检查传入的请求是否使用https，如果是，就不要再次重定向到https，而是像往常一样继续。否则，如果它是http，则通过附加https重定向它。

app.use (function (req, res, next) {
  if (req.secure) {
          next();
  } else {
          res.redirect('https://' + req.headers.host + req.url);
  }
});

经过多年研究从http到https的完美重定向，我在这里找到了完美的解决方案。

const http = require("http");
const https = require("https");

const { parse } = require("url");
const next = require("next");
const fs = require("fs");

const ports = {
http: 3000,
https: 3001
}

const dev = process.env.NODE_ENV !== "production";
const app = next({ dev });
const handle = app.getRequestHandler();

const httpsOptions = {
key: fs.readFileSync("resources/certificates/localhost-key.pem"),
cert: fs.readFileSync("resources/certificates/localhost.pem")
};

// Automatic HTTPS connection/redirect with node.js/express
// source: https://stackoverflow.com/questions/7450940/automatic-https- 
connection-redirect-with-node-js-express
app.prepare().then(() => {

// Redirect from http port to https
http.createServer(function (req, res) {
    res.writeHead(301, { "Location": "https://" + req.headers['host'].replace(ports.http, ports.https) + req.url });
    console.log("http request, will go to >> ");
    console.log("https://" + req.headers['host'].replace(ports.http, ports.https) + req.url);
    res.end();
}).listen(ports.http, (err) => {
    if (err) throw err;
    console.log("ready - started server on url: http://localhost:" + ports.http);
});

https.createServer(httpsOptions, (req, res) => {
    const parsedUrl = parse(req.url, true);
    handle(req, res, parsedUrl);
}).listen(ports.https, (err) => {
    if (err) throw err;
    console.log("ready - started server on url: https://localhost:" + ports.https);
});
});

我的情况下，我必须改变端口也听两个端口:

appr.get("/", (req, res) => {
  res.redirect('https://' + req.headers['host'].replace(PORT, PORTS) + req.url);
});
