And(/^the user makes the following changes in the response file "(.*)" and creates a uri with "(.*)" and wskey:$/) do |readFile, strURI,table|

  strRequestBody = $objFileIO.ReadFile(STR_FILE_SPEC + '/response/' + readFile)
  table.hashes.each do |rows|
    @request_uri = strRequestBody.gsub!(/#{rows[:parameter_in_response]}/, rows[:replace_with])
  end

  puts "this is url" + @request_uri   
end

Simply define it outside the loop, then the scoop will change.
