将http重定向到https express.js [英] Redirect http to https express.js

问题描述

我正在尝试在我的快速应用程序中将 http（80）重新路由到 https（443）。我正在使用一些中间件来做到这一点。如果我去我的 https://my-example-domain.com ，一切都很好。但是如果我去 http://my-example-domain.com ，它不会重定向，没有任何显示。

我还在我的ubuntu服务器上设置了一些iptables

  sudo iptables -A INPUT -i eth0 -p tcp  - dport 80 -j ACCEPT 
 sudo iptables -A INPUT -i eth0 -p tcp --dport 443 -j ACCEPT 
 sudo iptables -A INPUT -i eth0 -p tcp --dport 8443 -j ACCEPT 
 sudo iptables -A PREROUTING -t nat -i eth0 -p tcp --dport 443 -j REDIRECT --to-port 8443 
 
 
 
 
函数requireHTTPS（req，res，next）{
 if（！req.secure）{
 return res.redirect（'https：//'+ req.headers.host + req.url）; 
} 
 next（）; 
} 
 
 //所有环境
 app.set（'port'，process.env.PORT || 8443）; 
 app.set（'views'，path.join（__ dirname，'views'））; 
 app.set（'view engine'，'jade'）; 
 app.use（express.logger（'dev'））; 
 app.use（requireHTTPS）; // redirect to https 
 app.use（express.json（））; 
 app.use（express.urlencoded（））; 
 app.use（app.router）; 
 app.use（express.static（path.join（__ dirname，'public'）））; 
 
 app.get（'/'，function（req，res）{
 res.render（'index'）; 
}）
 
 https.createServer（options，app）.listen（8443）; 
  

所以我的问题是我只需要添加另一个 iptables 规则？或者我需要在我的应用程序中配置一些东西？

所以基于以下一个答案，我不认为它是一个中间件问题，而是一个端口问题。例如：如果我转到 http://my-example-domain.com ，则不起作用。但是如果添加端口8443， http://my-example-domain.com:8443 ，

解决方案

  var redirectApp = express（），
 redirectServer = http.createServer（redirectApp）; 
 
 redirectApp.use（function requireHTTPS（req，res，next）{
 if（！req.secure）{
 return res.redirect（'https：//'+ req.headers.host + req.url）; 
} 
 next（）; 
}）
 
 redirectServer.listen（8080）; 
  

I'm trying to reroute http (80) to https (443) in my express app. I'm using some middle ware to do this. If i go to my https://my-example-domain.com, everything is fine. But if I go to http://my-example-domain.com it does not redirect and nothing shows up.

I also have setup some iptables on my ubuntu server

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




function requireHTTPS(req, res, next) {
  if (!req.secure) {
    return res.redirect('https://' + req.headers.host + req.url);
  }
  next();
}

// all environments
app.set('port', process.env.PORT || 8443);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.logger('dev'));
app.use(requireHTTPS);  // redirect to https
app.use(express.json());
app.use(express.urlencoded());
app.use(app.router);
app.use(express.static(path.join(__dirname, 'public')));

app.get('/', function(req, res){
    res.render('index');
})

https.createServer(options, app).listen(8443);

So my question is do I just need to add another iptables rule? Or do I need to configure something in my app?

So based on one answer below, I don't think its a middleware problem, but a port issue. For example: if i go to http://my-example-domain.com, doesn't work. But if I add port 8443,http://my-example-domain.com:8443, it redirects fine.

解决方案

var redirectApp = express () ,
redirectServer = http.createServer(redirectApp);

redirectApp.use(function requireHTTPS(req, res, next) {
  if (!req.secure) {
    return res.redirect('https://' + req.headers.host + req.url);
  }
  next();
})

redirectServer.listen(8080);
