问题描述
我有一个正在使用的简单的html解析器(出于学习目的).
I have this simple html parser(for learning purposes) that I have been working on.:
require 'open-uri'
puts "Enter URL to parse HTML: "
url = gets.chomp
puts "Enter tag to parse from: "
tag = gets.chomp
response = open(url).read
title1 = response.index(tag)
title2 = response.index(tag.insert(1,'/')) -1
result = response[(title1 + tag.length - 1)..title2]
print result
，当我输入http://twitter.com时，出现以下错误消息:
and when I input http://twitter.com, I get this error message:
ERROR: `open_loop': redirection forbidden: http://twitter.com -> https://twitter.com/ (RuntimeError)
from /usr/local/rvm/rubies/ruby-2.1.4/lib/ruby/2.1.0/open-uri.rb:149:in `open_uri'
from /usr/local/rvm/rubies/ruby-2.1.4/lib/ruby/2.1.0/open-uri.rb:704:in `open'
from /usr/local/rvm/rubies/ruby-2.1.4/lib/ruby/2.1.0/open-uri.rb:34:in `open'
from /home/ubuntu/workspace/htmlparse.rb:6:in `<main>'
有什么建议或帮助吗?我是Ruby的新手，我知道其他html解析模块，但是我这样做是为了学习Ruby基础知识.谢谢.
Any advise or help? Im new to Ruby and I am aware of other html parsing modules, but Im doing this to learn Ruby basics. Thanks.
推荐答案
看看 open_uri_redirections 宝石.
它修补了Ruby的OpenURI，以允许从HTTP重定向到HTTPS或以其他方式进行重定向.
It patches Ruby's OpenURI to allow redirections from HTTP to HTTPS or the other way around.
