Question

在过去的两天里，我认为我已经浏览了与Net::HTTP相关的每篇可用（google'able）帖子中有关此SSL错误的信息： OpenSSL::SSL::SSLError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A

我首先尝试做的是连接到EtherPad服务器（https://test.titanpad.com），登录并使用rubygems＆amp; amp;下载zip存档。机械化;然而，遗憾的是，由于SSL-Error所述，我甚至没有达到这一点。在尝试从机械对象中调试问题后（通过在脚本中手动设置cert，ca_file，cert_store，verify_mode等），我更接近实际问题，尝试只需使用Net::HTTP

即可连接到https://test.titanpad.com

（在此示例中，我首先连接到https://encrypted.google.com以确保SSL 应该工作;尝试连接到EtherPad服务器从第6行开始）

irb(main):001:0> require 'net/https'
=> true
irb(main):002:0> google = Net::HTTP.new('encrypted.google.com', 443)
=> #<Net::HTTP encrypted.google.com:443 open=false>
irb(main):003:0> google.use_ssl = true
=> true
irb(main):004:0> google.ca_file = '/opt/local/share/curl/curl-ca-bundle.crt' if File.exists?('/opt/local/share/curl/curl-ca-bundle.crt')
=> "/opt/local/share/curl/curl-ca-bundle.crt"
irb(main):005:0> google.request_get('/')
=> #<Net::HTTPOK 200 OK readbody=true>

irb(main):006:0> etherpad = Net::HTTP.new('test.titanpad.com', 443)
=> #<Net::HTTP test.titanpad.com:443 open=false>
irb(main):007:0> etherpad.use_ssl = true
=> true
irb(main):008:0> etherpad.ca_file = '/opt/local/share/curl/curl-ca-bundle.crt' if File.exists?('/opt/local/share/curl/curl-ca-bundle.crt')
=> "/opt/local/share/curl/curl-ca-bundle.crt"
irb(main):009:0> etherpad.request_get('/')
OpenSSL::SSL::SSLError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A

    from (irb):9
    from /opt/local/bin/irb:12:in `<main>'

即使使用verify_mode OpenSSL::SSL::VERIFY_NONE，OpenSSL也会出局：

irb(main):010:0> etherpad.verify_mode = OpenSSL::SSL::VERIFY_NONE
=> 0
irb(main):011:0> etherpad.request_get('/')
OpenSSL::SSL::SSLError: SSL_connect SYSCALL returned=5 errno=0 state=SSLv2/v3 read server hello A

    from /opt/local/lib/ruby1.9/1.9.1/timeout.rb:99:in `timeout'

    from /opt/local/lib/ruby1.9/1.9.1/net/http.rb:744:in `start'

    from /opt/local/lib/ruby1.9/1.9.1/net/http.rb:1195:in `request_get'
    from (irb):11
    from /opt/local/bin/irb:12:in `<main>'

在进一步讨论openssl本身之后，事实证明在这种情况下真正的麻烦是必须强制使用SSLv3进行握手，使用titanpad.com后面的Jetty 6.1.20 server工作：

irb(main):001:0> require 'net/https'
=> true
irb(main):002:0> etherpad = Net::HTTP.new('test.titanpad.com', 443)
=> #<Net::HTTP test.titanpad.com:443 open=false>
irb(main):003:0> etherpad.use_ssl = true
=> true
irb(main):004:0> etherpad.ssl_version = "SSLv3"
=> "SSLv3"
irb(main):005:0> etherpad.ca_file = '/opt/local/share/curl/curl-ca-bundle.crt' if File.exists?('/opt/local/share/curl/curl-ca-bundle.crt')
=> "/opt/local/share/curl/curl-ca-bundle.crt"
irb(main):006:0> etherpad.request_get('/')
=> #<Net::HTTPFound 302 Found readbody=true>

现在，虽然这在使用Net::HTTP时显然有效，但是没有设置{strong>机械化中使用的SSL版本的选项...因此我会这样做如果有人能指出我如何通过所述gem oO强制执行SSLv3，那真的很高兴

再次感谢！

系统：Mac OSX 10.6.8 ruby 1.9.3p0（2011-10-30修订版33570）[x86_64-darwin10] 使用mechanize安装的rubygems：domain_name（0.5.2），mechanize（2.1.1），net-http-digest_auth（1.2），net-http-persistent（2.4.1），nokogiri（1.5.0），ntlm-http（ 0.1.1），unf（0.0.4），unf_ext（0.0.4），webrobots（0.0.13）

已通过将ssl_version功能从Net :: HTTP（通过net-http-persistent）移植到Mechanize v.2.1.2（见https://github.com/tenderlove/mechanize/commit/4a228899855e0676ab69c2bf548170c8717465d8）来修复。

使用机械化（甚至Net :: HTTP）与ruby 1.9返回'OpenSSL :: SSL :: SSLError' - 如何强制使用SSLv3？
