Can not open localhost by running Ruby on Rails application

I am trying to run a ruby script in rails application using system call, like

def runSystemCall
    system("ruby /path/to/ruby/script/watir.rb localhost:3000/articles/14")
end

and watir.rb:

def watir(url)
    bb = Watir::Browser.new :chrome
    bb.goto "#{url[0]}"
end

watir(ARGV)

when running this in rails application, a browser opened and stay in a status of Waiting for localhost..., until error 

.rvm/rubies/ruby-2.1.2/lib/ruby/2.1.0/net/protocol.rb:158:in `rescue in rbuf_fill': Net::ReadTimeout (Net::ReadTimeout)

loaded the website localhost:3000/articles/14 opened. Dose anyone know why?

and, when run this in a terminal

$ ruby /path/to/ruby/script/watir.rb localhost:3000/articles/14

a browser opened and open website localhost:3000/articles/14 That's what I expected.

Solution

  • Your local server is single threaded. That means it can only handle one request at a time. If one local request wants to load an other page from the same local server, than you need at least two local threads.
