Question

我是watir和Ruby的新手。我写了一个小代码，试图打开一个链接，关闭浏览器，然后再次打开链接。

require 'watir-webdriver'
br = Watir::Browser.new :firefox
br.goto "http://google.co.in/"
br.close
br.goto "http://google.co.in/"

当我尝试执行此操作时，我收到以下错误

/usr/lib/ruby/1.9.1/net/http.rb:763:in `initialize': Connection refused - connect(2) (Errno::ECONNREFUSED)
from /usr/lib/ruby/1.9.1/net/http.rb:763:in `open'

请告诉我该怎么做。感谢。

就像人类一样，Watir无法在封闭的浏览器中访问页面。您必须创建另一个浏览器实例，这将打开另一个浏览器窗口。在新的浏览器窗口中，您可以访问另一个网页。

require 'watir-webdriver'
br = Watir::Browser.new :firefox
br.goto "http://google.co.in/"
br.close
br = Watir::Browser.new :firefox
br.goto "http://google.co.in/"

尝试关闭并打开浏览器时连接被拒绝错误
