ruby-on-rails - 猴子修补 use_ssl= 方法适用于 Net :HTTP but not for OpenURI in Ruby 1. 9.3？

Question

背景:

• ruby 1.9.3
• rails 3.2.16
• Windows 7 x64

问题

我正在努力解决臭名昭著的问题

SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed

在我执行的每个 HTTP 请求中包含我的证书时出错。为此，我猴子修补 Net::HTTP#use_ssl=:

# lib/gem_ext/net_http.rb
require 'open-uri'
require 'net/https'

module Net
  class HTTP
    alias_method :original_use_ssl=, :use_ssl=

    def use_ssl=(flag)
      store = OpenSSL::X509::Store.new
      store.set_default_paths # Auto-include the system CAs.

      Dir[Rails.root + 'config/certificates/*'].each do |cert|
        puts "Adding cert: #{cert}"
        store.add_cert(OpenSSL::X509::Certificate.new(File.read(cert)))
      end

      self.cert_store = store
      self.verify_mode = OpenSSL::SSL::VERIFY_PEER
      self.original_use_ssl = flag
    end
  end
end

现在，使用 Net::HTTP 执行请求，例如:

> uri = URI.parse('https://internal-app/secure_url.json?foo=bar')
> Net::HTTP.start(uri.host, uri.port, :read_timeout => 10.minutes, :use_ssl => uri.scheme == 'https') do |http|
>  http.request Net::HTTP::Get.new(uri.request_uri)
> end
Adding cert: config/certificates/cert1.cer
Adding cert: config/certificates/cert2.cer
=> #<Net::HTTPOK 200 OK readbody=true>

完美运行。

但是，当我尝试使用 OpenURI 时，我认为它只是 Net::HTTP(和其他 IO 操作)的包装器，例如:

> require 'open-uri'    
> open('https://our-all/secure_url.json?foo=bar', 'r', :read_timeout => 10.minutes)
Adding cert: config/certificates/cert1.cer
Adding cert: config/certificates/cert2.cer
#<Class:0x870e2e0>: SSL_connect returned=1 errno=0 state=SSLv3 read server certi
  from D:/Ruby/Ruby193/lib/ruby/1.9.1/net/http.rb:800:in `connect'
  from D:/Ruby/Ruby193/lib/ruby/1.9.1/net/http.rb:800:in `block in connect

所以我可以看到我的猴子修补方法被击中(“添加证书..”)，但我仍然收到错误。似乎有别的东西在压倒它。有什么想法吗？

谢谢

我设法想出了一个解决方案(前一段时间，所以我希望它仍然适用)。

根据我的代码中的评论，我需要猴子补丁 cert_store= 以及“as use_ssl= as Net::HTTP和 OpenURI.open_http以不同的顺序调用这些方法，因此我们需要确保一致地添加证书。”

所以，这是我的解决方案:

module Net
  class HTTP

    alias_method :original_use_ssl=, :use_ssl=
    def use_ssl=(flag)
      store = OpenSSL::X509::Store.new
      store.set_default_paths # Auto-include the system CAs.
      self.cert_store = store # Now include internal certificates.
      self.verify_mode = OpenSSL::SSL::VERIFY_PEER # Force verification.
      self.original_use_ssl = flag
    end

    alias_method :original_cert_store=, :cert_store=
    def cert_store=(store)
      Dir[Rails.root + 'config/certificates/*'].each do |cert|
        store.add_cert(OpenSSL::X509::Certificate.new(File.read(cert)))
      end

      self.original_cert_store = store
    end
  end
end
