在过去的 2 天里，我想我已经阅读了所有关于这个 SSL-Error 的可用（google'able）帖子Net::HTTP： 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），登录并通过使用 ruby​​gems & mechanize 下载 zip-archive；但是，不幸的是，由于说，我什至没有达到这一点SSL-Error。在尝试从机械化对象中调试问题后（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，尝试连接到https://test .titanpad.com只需使用Net::HTTP：

（在这个例子中，我首先连接到https://encrypted.google.com以确保，SSL 应该可以解决；连接到 EtherPad 服务器的尝试从第 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 也会退出：

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 (irb):11
    from /opt/local/bin/irb:12:in `<main>'

在进一步玩弄了 openssl 本身之后，事实证明，在这种情况下，真正的麻烦在于必须强制使用 SSLv3 才能与Jetty 6.1.20 server后面的 titanpad.com 握手：

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，虽然这在使用时显然有效Net::HTTP，但没有这样的选项可以设置在MechanizeSSL中使用的版本......因此，如果有人能向我指出如何通过所述 gem 强制执行 SSLv3，我会非常高兴oO

再次感谢！

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