OpenUri造成401 HTTPS URL未经授权的错误 [英] OpenUri causing 401 Unauthorized error with HTTPS URL

问题描述

我补充说，从需要使用与验证的HTTPS连接的源擦伤的XML页面功能。我试图用Ryan Ba​​tes的Railscast＃190解决方案，但我遇到一个401认证错误。

I am adding functionality that scrapes an XML page from a source that requires the use of an HTTPS connection with authentication. I am trying to use Ryan Bates' Railscast #190 solution but I'm running into a 401 Authentication error.

下面是我测试的Ruby脚本：

Here is my test Ruby script:

require 'rubygems'
require 'nokogiri'
require 'open-uri'

url = "https://biblesearch.americanbible.org/passages.xml?q[]=john+3:1-5&version=KJV"
doc = Nokogiri::XML(open(url, :http_basic_authentication => ['username' ,'password']))
puts doc.xpath("//text_preview")

下面是控制台的输出后，我跑我的脚本：

Here is the output of the console after I run my script:

/usr/local/rvm/rubies/ruby-1.9.3-p194/lib/ruby/1.9.1/net/http.rb:799:in `connect': SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (OpenSSL::SSL::SSLError)

在我的研究，我看到了一个帖子中，有人提出，在1.9.3可以用于下列选项：

In my research, I saw one post in which it was suggested that in 1.9.3 the following option could be used:

doc = Nokogiri::XML(open(url, :http_basic_authentication => ['username' ,'password'], :ssl_verify_mode => OpenSSL::SSL::VERIFY_NONE))

不过，这也不能工作。我想AP preciate一些见解应对这一挑战。

However, this did not work either. I would appreciate some insight into addressing this challenge.

推荐答案

给定的URL将被重定向到 /v1/KJV/passages.xml?q [] =约翰+ 3％3A1-5 ，HTTP状态code 302找到。 OpenURI理解重定向，但自动删除认证头（也许）出于安全原因。 （*）

The given URL will be redirected to /v1/KJV/passages.xml?q[]=john+3%3A1-5 with HTTP status code 302 Found. OpenURI understands the redirection, but automatically deletes authentication header (maybe) for security reason. (*)

如果您访问http://biblesearch.americanbible.org/v1/KJV/passages.xml?q[]=john+3%3A1-5直接，你会得到预期的结果。 ： - ）

If you access "http://biblesearch.americanbible.org/v1/KJV/passages.xml?q[]=john+3%3A1-5" directly, you will get the expected result. :-)

（*）可以在开放式uri.rb找到：

if redirect
  ### snip ###
  if options.include? :http_basic_authentication
    # send authentication only for the URI directly specified.
    options = options.dup
    options.delete :http_basic_authentication
  end
