机械化如何获取当前网址

I have this code

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

As you can see this code should go to the next page.

正如您所看到的，此代码应该转到下一页。

The next_page should have url http://something.com/?page=2

next_page应该有网址http://something.com/?page=2

How to get current url for next_page?
