Add a .host() method to set a host other than 127.0.0.1

[mikec]

This allows you to set the server hostname before making a
request. If no hostname is set then it defaults to 127.0.0.1

yes yes yes

If somebody looks for an opportunity virtual hosts testing. My solution is below.

function createVhostTester(app, vhost) {
  const real = supertest(app);
  const proxy = {};

  Object.keys(real).forEach(methodName => {
    proxy[methodName] = function() {
      return real[methodName]
        .apply(real, arguments)
        .set('host', vhost);
    }
  });

  return proxy;
}

var api = createVhostTester(appInstance, 'api.example.com');
var appTest = createVhostTester(appInstance, 'app.example.com');

@mikelax this PR could fix problems with IP V6 as well since one could pass ::1 as address 👍

Hello! Is it likely this will get merged?

[jobackman]

Nice work! I would also love for this to be a feature in supertest 👍

guys, any update on this? Would be very great to see this added soon...

[lauzierj]

I believe you can do this using the example below:

supertest(app)
  .get('/path/to/thing')
  .set('host', 'api.example.com');

Express 4 then shows req.subdomains as ['api'].

@lauzierj many thanks for providing that example, worked nicely. So many people waiting for it and it got already added. No idea, maybe not documented? At least I had not found anything at the time I was looking for that feature.
