Mechanize 收到“Errno::ECONNRESET：连接由对等方重置 - SSL_connect”

我无法让 Mechanize 加载曾经正常工作的页面——它确实失败了，并显示Errno: ECONNRESET: Connection reset by peer - SSL_connect信息。关于我应该尝试什么或我应该查看的细节有什么建议吗？ （请参阅下面的“我尝试过的方法”...）

Update 1

从中得到暗示相关的 S.O.邮政 https://stackoverflow.com/questions/12443258/ssl-connect-error-when-accessing-shopify-api-with-rubygem，我尝试直接访问该网站Net::HTTP。当我设置http.ssl_version = :TLSv1，我得到一个重定向而不是一个错误（应该是这样）。所以我的问题变成：如何配置 Net::HTTP 的底层ssl_version内部参数Mechanize?

谢谢...

症状：

$ rails console
>> a = Mechanize.new
=> #<Mechanize:0x007fd26789b8e0 ...>
>> p = a.get("http://sce.com")
# (...after a long pause...)

我尝试过的：

• 我已经在 Firefox Web 浏览器中尝试了相同的 URL。有用。
• 我已经明确设置了机械化request_headers完全模仿 Firefox 浏览器。不用找了。
• 我已经更新了我的ssl/cert.pem文件（第二次），如中所述这个S.O帖子 https://stackoverflow.com/questions/19150017/ssl-error-when-installing-rubygems-unable-to-pull-data-from-https-rubygems-o。不用找了。
• 我尝试过不同的网站：www.pge.com and www.sdge.com。两者都有效。有一些不一样的地方www.sce.com site.

Net::HTTP 成功

这是 Net::HTTP 工作的示例：

$ irb
>> require 'net/https'
=> true
>> require 'uri'
=> false
>> uri = URI.parse("https://www.sce.com/")
=> #<URI::HTTPS:0x007facab8f6ba0 URL:https://www.sce.com/>
>> http = Net::HTTP.new(uri.host, uri.port)
=> #<Net::HTTP www.sce.com:443 open=false>
>> http.use_ssl = true
=> true
>> http.ssl_version = :TLSv1     # <= this line makes all the difference
=> :TLSv1
>> r = http.start { |agent| p agent.get(uri.path) }
=> #<Net::HTTPFound 302 Found readbody=true>
>> r.to_hash
=> {"content-language"=>["en-US"], "date"=>["Fri, 18 Oct 2013 01:00:07 GMT"], "location"=>["https://www.sce.com/wps/portal/home/!ut/p/b1/04_Sj9CPykssy0xPLMnMz0vMAfGjzOIt3Q1cPbz8DTzdQwKNDTyNAw38gh0djQ0MzIAKIoEKDHAARwNC-sP1o8BK8Jjg55Gfm6pfkBthoOuoqAgAgIrzaA!!/dl4/d5/L2dBISEvZ0FBIS9nQSEh/"], "p3p"=>["CP=\"NON CUR OTPi OUR NOR UNI\""], "server"=>["IBM_HTTP_Server"], "transfer-encoding"=>["chunked"], "x-powered-by"=>["Servlet/3.0"], "set-cookie"=>["PD_STATEFUL_d55ece64-8d9a-11e2-84a1-0050560010d6=%2Fwps; Path=/", "session_www=740796608.47873.0000; path=/"]}

Mechanize 邮件列表中的人们友好地提供了答案：

agent = Mechanize.new do |a|
  a.ssl_version = :TLSv1
end
