How to find out the remote Address in node.js if it is HTTPS request?

HI. in node.js, if it is http request, I can get the remoteAddress at req.connection.remoteAddress,

As well req.headers['x-forwarded-for'] is easily manipulated so you need a properly configured proxy server.

Is better to check req.connection.remoteAddress against a list of known proxy servers before to go with req.headers['x-forwarded-for'].

var ip = req.headers['x-forwarded-for'] || 
     req.connection.remoteAddress || 
     req.socket.remoteAddress ||
     req.connection.socket.remoteAddress;

Note that sometimes you can get more than one ip address in req.headers['x-forwarded-for'], specially when working with mobile phones accessing your server (wifi and carrier data).

Since googling "express js ip" directly points to here, this is somehow relevant.

Express 3.0.0 alpha now offers a new way of retrieving IP adresses for client requests. Simply use req.ip. If you're doing some proxy jiggery-pokery you might be interested in app.set("trust proxy", true); and req.ips.

I recommend you to read the whole discussion in the Express Google Group.

It appears something is strange/broken indeed. As of node 0.4.7, it seems http has remoteAddress available on:

  • req.connection.remoteAddress
  • req.socket.remoteAddress

on https, both of these are undefined, but

  • req.connection.socket.remoteAddress

does work. That one isn't available on http though, so you need to check carefully. I cannot imagine this behavior is intentional.
