How to get current domain address in sails.js

Question

I trying to get current web address using sails.js.

I tried the following:

req.param(\'host\') and req.param(\'X-Forwarded-Protocol\') 

Answer 1

I have tried some examples I have found in google but nothing seemed to work at least in my local machine.

1. Using this in my local machine returned:

   req.ip;  -->  ::1
   

2. Using this in my local machine returned:

   req.headers['x-forwarded-for'];  -->  undefined
   

3. Finally, using this in my local machine returned:

   var paramIp = req.headers['x-forwarded-for'] ||
               req.connection.remoteAddress ||
               req.socket.remoteAddress ||
               req.connection.socket.remoteAddress;  -->  ::1
   

Nothing seemed to work. Then I tried in production environment and the first example returned:

req.ip;  -->  ::ffff:10.155.43.243

It seems to be working but as you can see it is an IPv6 ip address so that's not what I wanted.

And the example number 3 returned:

187.214.247.196

So that's excellent because that's what I needed.

All I have to said is that the example number 3 worked fine but just in production environment (using Heroku) not for development in my local machine.
