Simple HTTP->HTTPS Proxy Example?

[cweichen]

Hi,

I'm a node/node-http-proxy novice, and I'd like to use node-http-proxy to create an HTTP->HTTPS proxy server. I.e. a client would connect to the proxy over HTTP, and on the back-end it would talk to an HTTPS target web server. The two examples given are for HTTPS->HTTP and HTTPS->HTTPS, but not HTTP->HTTPS.

Maybe it's obvious from these examples how to do it, but I'm not able to figure it out.

Here's a sample of my code:

var httpProxy = require('http-proxy');

httpProxy.createServer(function (req, res, proxy) {
  proxy.proxyRequest(req, res, {
    host: 'secure.target.host',
    port: 443,
    https: true
  });
}).listen(8000);

When I try to connect to http://localhost:8000 I get a 500 Internal Server Error with the body

An error has occurred: {"code":"ECONNRESET"}

If anyone can show me what I'm doing wrong, that would be greatly appreciated! Thanks!

Never mind, I figured it out. I just had to ignore all the extraneous code in the HTTPS->HTTPS example. This will do it:

var httpProxy = require('http-proxy');

var options = {
    target: {
        https: true
    }
}

httpProxy.createServer(443, 'secure.target.host', options).listen(8000);

Beautiful! Thanks node-http-proxy!

This doesn't work for me. I get:

An error has occurred: {"code":"ECONNRESET"}

(I have tried different hosts, of course)

Can you repost your gist? :)

Figured this out myself after tearing my hair out a bit. The above solution wouldn't work for me because I needed to inspect the request before proxying it. You need to place the https: true option inside a target object.

require('http-proxy').createServer(function (req, res, proxy) {
  // Inspect request and decide whether to proxy, then...
  proxy.proxyRequest(req, res, {
    host: 'secure.target.host',
    port: 443,
    target: {
       https: true
    }
  });
}).listen(8080);

There's an example in the examples folder now: https://github.com/nodejitsu/node-http-proxy/blob/caronte/examples/http/proxy-http-to-https.js

httpProxy.createProxyServer({
  target: 'https://google.com',
  agent  : https.globalAgent,
  headers: {
    host: 'google.com'
  }
}).listen(8011);

Worked for me.

In case someone's having problem with it, I've created a simple working repo: https://github.com/ericmdantas/simple-node-https-proxy

@ericmdantas I'm trying to use your repo to access secured web pages, but it seems to not be working because I get Secure Connection Failed in the web page...

[ericmdantas]

@Valeriu92, when I access https://localhost:9998/api/server2 I get the payload correctly: {"msg2":"came from server2"}

It works for me only with secure: false in options which is unfortunate, becauase the target server has valid letsencrypt certificate. How do I debug the SSL layer verbosely to see why is the 'first certificate' invalid?

[rickysahu]

I had to use these options

{
  secure: false,
  target: 'https://localhost:443',
}
