if use proxy, can't show the real ip

[wohugb]

change getip function in morgan module index.js, and req.headers['x-real-ip'] will show the real ip!

@wohugb You can custom the remote-addr token, like the below:

morgan.token('remote-addr', getip)

function getip(req) {
 // do something
}

@wohugb You can custom the remote-addr token, like the below:

morgan.token('remote-addr', getip)

function getip(req) {
 // do something
}

works well with proxy-addr

import proxyaddr from 'proxy-addr';
morgan.token('remote-addr', function(req, res) {
  return proxyaddr.all(req);
});
