Get hostname of URL in ruby on rails

I am making rails app and I need to get just hostname of my URL from my one of Rails controllers.

If my URL is http://www.example.com/path/0,then I just want to extract www.example.com part. How can I do this? I found request.base_url but this returns http://www.example.com which I do not want.

In javascript there is a function, window.location.hostname. I wonder there is a equivalent in Ruby on Rails.

Based on URI module, we can also use #authority method in case you need the port as well.

uri = URI("http://lvh.me:3000/path/0")
uri.authority # => "lvh.me:3000"

Check more about URI #authority method

I am using Rails 4.2

We can get host and port with one method 

request.host_with_port
=> "localhost:3002"

The URI module can do this for you.

uri = URI("http://www.example.com/path/0")
uri.host # => "www.example.com"

You can use request.host to get exact your URL which you want.

And you can use request.port to get your port from url
