将4.x重定向到http [英] express 4.x redirect http to https

问题描述

我有以下代码：

var https        = require('https');
var http         = require('http');
var express      = require('express');
var app          = express();
var router       = express.Router();

app.use('/', router);

//listen server on https
var server = https.createServer(config.sslCredential, app);
server.listen(config.serverPort);

//listen server on http, and always redirect to https
var httpServer = http.createServer(function(req,res){
    res.redirect(config.serverDomain+req.url);
});
httpServer.listen(config.httpServerPort);

但不知何故，我无法将https请求重定向到https请求，我该怎么办正确使用express 4.x的node.js？

but somehow i can't get https request to be redirected into https request, how should i do this correctly on node.js with express 4.x ?

推荐答案

从我自己的答案（其中btw是on express 3.0）

Quoting a middleware solution from my own answer (which btw was on express 3.0)

app.all('*', ensureSecure); // at top of routing calls

http.createServer(app).listen(80)
https.createServer(sslOptions, app).listen(443)

function ensureSecure(req, res, next){
  if(req.secure){
    // OK, continue
    return next();
  };
  // handle port numbers if you need non defaults
  // res.redirect('https://' + req.host + req.url); // express 3.x
  res.redirect('https://' + req.hostname + req.url); // express 4.x
}
