我下面的代码不起作用。在我看来，我必须提交一些隐藏的字段。有谁知道

如何提交隐藏字段？

如果我需要提交名称和值或仅提交其中之一？

如何登录 vBulleting v3.6

一些文本作为代码显示在文本下方

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'] = 'username'
login_form['vb_login_password]'] = '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) }

Answer 1

vBulletin 需要密码的 md5，而不是实际密码。因此，如果您捕获网络浏览器发送的内容，则可以使用该值。或者您必须使用 md5 库(未测试)从任何密码中创建 md5 哈希。

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) }
