How to specify a read timeout for a Net::HTTP::Post.new request in Ruby 2

Question

I have a post happening to a rails application from a ruby script. The script creates a variable request as

request = Net::HTTP::Post.new(url.path)

I catch both OpenTimeout and ReadTimeout and it's work. test in Ruby:2.6.5

def ping(host, port)
    begin
        url = URI.parse("http://#{host}:#{port}/ping")
        req = Net::HTTP::Get.new(url.to_s)

        # setting both OpenTimeout and ReadTimeout
        res = Net::HTTP.start(url.host, url.port, :open_timeout => 3, :read_timeout => 3) {|http|
          http.request(req)
        }

        if JSON.parse(res.body)["ok"]
          # return true
          STDERR.puts "#{host}:#{port} is reachable"
        else
          STDERR.puts "#{host}:#{port} is NOT reachable"
        end
    rescue Net::ReadTimeout => exception
        STDERR.puts "#{host}:#{port} is NOT reachable (ReadTimeout)"
    rescue Net::OpenTimeout => exception
        STDERR.puts "#{host}:#{port} is NOT reachable (OpenTimeout)"
    end

end

ping("#{ENV['FIRST_HOST']}", 2345)
ping("#{ENV['SECOND_HOST']}", 2345)
