我认为 mechanize 默认遵循重定向......我的脚本在重定向页面结束。我该如何处理？
require 'rubygems'
require 'mechanize'
agent = WWW::Mechanize.new
page = agent.get("http://www.vbulletin.org/forum/index.php")
login_form = page.form_with(:action => 'login.php?do=login')
login_form['vb_login_username'] = 'user name'
login_form['vb_login_password'] = ''
login_form['vb_login_md5password_utf'] = 'md5 hash from the password'
login_form['vb_login_md5password'] = 'md5 hash from the password'
page = agent.submit login_form
#Display welcome message if logged in
puts page.parser.xpath("/html/body/div/table/tr/td[2]/div/div").xpath('text()').to_s.strip
output = File.open("login.html", "w") {|f| f.write(page.parser.to_html) }
重定向页面html

最佳答案
Mechanize 中有一个选项可以做到这一点。默认情况下，Mechanize 不遵循元刷新，但我们可以设置该选项。
agent.follow_meta_refresh = true
