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>}
- {Meta_refresh}
- {title "Hacker News"}
- {iframes}
- {frames}
