ruby – 机械化如何获取当前网址

发布时间：2020-12-16 20:24:15 所属栏目：百科来源：网络整理

导读：我有这个代码 require 'mechanize'@agent = Mechanize.newpage = @agent.get('http://something.com/?page=1')next_page = page.link_with(:href=/^?page=2/).click 正如你可以看到这个代码应该去下一页. next_page应该有url http://something.com/?page=2

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

正如你可以看到这个代码应该去下一页.

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}
 {links
  #<Mechanize::Page::Link "" "http://ycombinator.com">
  #<Mechanize::Page::Link "Hacker News" "news">
  #<Mechanize::Page::Link "new" "newest">
  #<Mechanize::Page::Link "comments" "newcomments">

  #<Mechanize::Page::Link "login" "newslogin?whence=%6e%65%77%73">
  #<Mechanize::Page::Link "" "vote?for=3803568&dir=up&whence=%6e%65%77%73">
  #<Mechanize::Page::Link

  #<Mechanize::Page::Link "" "vote?for=3802515&dir=up&whence=%6e%65%77%73">
  # Omitted for brevity...

next_page.uri
 => #<URI::HTTP:0x00000001fa7818 URL:http://news.ycombinator.com/news2> 

next_page.uri.to_s
 => "http://news.ycombinator.com/news2"
