使用Mechanize进行基本和表单身份验证(Ruby)

Question

我正在尝试登录公司内部网上的一个站点,该站点具有基本的身份验证弹出对话框和基于表单的身份验证.这是我正在使用的代码(导致401 => Net :: HTTPUnauthorized错误):

require 'rubygems'
require 'mechanize'
require 'logger'

agent = WWW::Mechanize.new { |a| a.log = Logger.new("mech.log") }
agent.user_agent_alias = 'Windows Mozilla'
agent.basic_auth('username','password')
agent.get('http://example.com') do |page|
  puts page.title
end

这导致401 => Net :: HTTPUnauthorized错误.以下是mech.log信息:

I, [2011-03-13T17:25:22.819723 #22128]  INFO -- : status: 401

在这一点上,我只是试图通过第一次基本身份验证.我注意到有一件事是服务器是IIS,而在Mechanize文档中有一个名为gen_auth_headers()的公共函数,但是在gem的代码中我使用的这个函数不存在,加上他在做什么在代码中超出了我.

TIA,Nabs

Answer 1

auth方法将在机械化版本3中删除,因此必须由add_auth替换,并提供应用这些凭据的URI.

require 'rubygems'
require 'mechanize'

agent = Mechanize.new
agent.user_agent_alias = 'Windows Mozilla'
agent.add_auth('http://example.com', 'username', 'password')
agent.get('http://example.com') do |page|
  puts page.title
end

Answer 2

使用Mechanize#auth

require 'rubygems'
require 'mechanize'
require 'logger'

agent = WWW::Mechanize.new { |a| a.log = Logger.new("mech.log") }
agent.user_agent_alias = 'Windows Mozilla'
agent.auth('username', 'password')
agent.get('http://example.com') do |page|
  puts page.title
end
