我有这个代码
require 'mechanize'
@agent = Mechanize.new
page = @agent.get('http://something.com/?page=1')
next_page = page.link_with(:href=>/^?page=2/).click
next_page应该有url http://something.com/?page=2
如何获取next_page的当前网址？
解决方法
next_page.uri.to_s
应该是你要找的
你可以在http://mechanize.rubyforge.org/Mechanize/Page/Link.html找到这个
为了测试目的,我在irb中进行了以下操作：
require 'mechanize'
@agent = Mechanize.new
page = @agent.get('http://news.ycombinator.com/news')
=> #<Mechanize::Page
{url #<URI::HTTP:0x00000001ad3198 URL:http://news.ycombinator.com/news>}
