Get client's IP address in Sinatra?

Question

This is a really simple question, but I cannot find any mention of this, anywhere..

How do I get the client\'s IP address from in Sinatra?

get \'/\'          


        

Answer 1

Sinatra provides a request object, which is the interface to the client request data that you should be using.

Using request.ip is the preferred method to find the client's IP address:

get '/' do
  "Your IP address is #{request.ip}"
end

Answer 2

I was coming to post the answer anyway.. so:

get '/' do
"Your IP address is #{ @env['REMOTE_ADDR'] }"
end

Sinatra uses the Rack::Request API, so you can use a lot of things available in it.
Also a link to the Sinatra doc's.
