Express vhosts + https

Question

有什么方法可以用https在Express上运行虚拟主机吗？我当前的代码（非SSL）如下所示：

var express = require('express');
var vhost = require('vhost');
var path = require('path');

var appOne = express();
var appTwo = express();
var appVhosts = module.exports = express();

appOne.use(express.static(path.join(__dirname, 'pages')));

appTwo.get('/', function(req, res){
    res.send('That service isn\'t up right now!')
});

app.use(vhost('siteone.com', appOne));
app.use(vhost('sitetwo.com', appTwo));

appVhosts.listen(80);

但是，据我所知，https模块只接受一个ssl证书。

Answer 1

显然，https.Server继承自tls.Server，它提供了一种叫做addContext()的方法。您可以在那里配置多个证书。我还写了一个非常小的包，使用这种方法来实现结果，https://www.npmjs.com/package/vhttps。你可以在那里查看我的实现。

Answer 2

您需要为每个应用定义SSL选项并分配给每个应用，如下所示：

// (A) read SSL files
var fs = require('fs');
var appOneSSLOps = {
  key:  fs.readFileSync('./path_to_file/private.key'),
  cert: fs.readFileSync('./path_to_file/certificate.crt')
}
var appTwoSSLOps = {
  key:  fs.readFileSync('./path_to_file/private2.key'),
  cert: fs.readFileSync('./path_to_file/certificate2.crt')
}

// (B) assign SSL files to app
var https = require('https');
var appOneServer = https.createServer(appOneSSLOps , appOne).listen(443);
var appTwoServer = https.createServer(appTwoSSLOps , appTwo).listen(80);

// (C) route 80 to 443 - > on your machine route port 80 to 443 either manually or by child_process: I assume you are using linux Ubuntu System
childProcess = require('child_process');
var optionExec = {timeout: 3000}; //option(s) for childProcess.exec
childProcess.exec(
  'sudo iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 80 -j REDIRECT --to-port 443',
  optionExec,
  function(err, stdout, stderr) {

  }
);

// (D) then enforce SSL - I assume appOne is the main app.
appOne.use(function(request, response, next) {
  if(!request.secure) {
    response.redirect('https://' + request.headers.host + request.url);
  }
  next();
});

注意：我认为appOne是主要的应用程序。
