Ruby on rails 检索PEM证书：SSL\u connect返回=1 errno=0 state=SSLv3读取服务器证书B:证书验证失败

和其他许多人一样，我也遇到了Ruby的错误：SSL\u connect返回=1 errno=0 state=SSLv3读取服务器证书B:证书验证失败

我下载了一个cacert.pem，并尝试这样添加它：

require 'net/http'

# create a path to the file "C:\RailsInstaller\cacert.pem"
cacert_file = File.join(%w{c: RailsInstaller cacert.pem})

Net::HTTP.start("curl.haxx.se") do |http|
  resp = http.get("/ca/cacert.pem")
  if resp.code == "200"
    open(cacert_file, "wb") { |file| file.write(resp.body) }
    puts "\n\nA bundle of certificate authorities has been installed to"
    puts "C:\\RailsInstaller\\cacert.pem\n"
    puts "* Please set SSL_CERT_FILE in your current command prompt session with:"
    puts "     set SSL_CERT_FILE=C:\\RailsInstaller\\cacert.pem"
    puts "* To make this a permanent setting, add it to Environment Variables"
    puts "  under Control Panel -> Advanced -> Environment Variables"
  else
    abort "\n\n>>>> A cacert.pem bundle could not be downloaded."
  end
end

require 'open-uri'
require 'net/https'

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

    def use_ssl=(flag)
      self.ca_file = Rails.root.join('lib/ca-bundle.crt')
      self.verify_mode = OpenSSL::SSL::VERIFY_PEER
      self.original_use_ssl = flag
    end
  end
end

就像这样：

require 'net/http'

# create a path to the file "C:\RailsInstaller\cacert.pem"
cacert_file = File.join(%w{c: RailsInstaller cacert.pem})

Net::HTTP.start("curl.haxx.se") do |http|
  resp = http.get("/ca/cacert.pem")
  if resp.code == "200"
    open(cacert_file, "wb") { |file| file.write(resp.body) }
    puts "\n\nA bundle of certificate authorities has been installed to"
    puts "C:\\RailsInstaller\\cacert.pem\n"
    puts "* Please set SSL_CERT_FILE in your current command prompt session with:"
    puts "     set SSL_CERT_FILE=C:\\RailsInstaller\\cacert.pem"
    puts "* To make this a permanent setting, add it to Environment Variables"
    puts "  under Control Panel -> Advanced -> Environment Variables"
  else
    abort "\n\n>>>> A cacert.pem bundle could not be downloaded."
  end
end

require 'open-uri'
require 'net/https'

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

    def use_ssl=(flag)
      self.ca_file = Rails.root.join('lib/ca-bundle.crt')
      self.verify_mode = OpenSSL::SSL::VERIFY_PEER
      self.original_use_ssl = flag
    end
  end
end

我甚至试图取消支票：

require 'faraday'
module Faraday
class Adapter
 class NetHttp < Faraday::Adapter
  def call(env)
    super

    is_ssl = env[:url].scheme == 'https'

    http = net_http_class(env).new(env[:url].host, env[:url].port || (is_ssl ? 443 : 80))
    if http.use_ssl = is_ssl
      ssl = env[:ssl]
      if ssl[:verify] == false
        http.verify_mode = OpenSSL::SSL::VERIFY_NONE
      else
        http.verify_mode = OpenSSL::SSL::VERIFY_NONE # <= PATCH or HACK ssl[:verify]
      end
      http.cert    = ssl[:client_cert] if ssl[:client_cert]
      http.key     = ssl[:client_key]  if ssl[:client_key]
      http.ca_file = ssl[:ca_file]     if ssl[:ca_file]
    end
    req = env[:request]
    http.read_timeout = net.open_timeout = req[:timeout] if req[:timeout]
    http.open_timeout = req[:open_timeout]               if req[:open_timeout]

    full_path = full_path_for(env[:url].path, env[:url].query, env[:url].fragment)
    http_req  = Net::HTTPGenericRequest.new(
      env[:method].to_s.upcase,    # request method
      (env[:body] ? true : false), # is there data
      true,                        # does net/http love you, true or false?
      full_path,                   # request uri path
    env[:request_headers])       # request headers

    if env[:body].respond_to?(:read)
      http_req.body_stream = env[:body]
      env[:body] = nil
    end

    http_resp = http.request http_req, env[:body]

    resp_headers = {}
    http_resp.each_header do |key, value|
      resp_headers[key] = value
    end

    env.update \
      :status           => http_resp.code.to_i,
      :response_headers => resp_headers,
      :body             => http_resp.body

    @app.call env
  rescue Errno::ECONNREFUSED
    raise Error::ConnectionFailed.new(Errno::ECONNREFUSED)
  end

  def net_http_class(env)
    if proxy = env[:request][:proxy]
      Net::HTTP::Proxy(proxy[:uri].host, proxy[:uri].port, proxy[:user], proxy[:password])
    else
      Net::HTTP
    end
  end
 end
end
end

所以我打开了

https://myserver.com/Request.ashx

在chrome中请求，单击小锁图标以获取证书详细信息。但是我找不到任何要导出的PEM文件。我可以看出这是一个科摩多证书。我没有自己的服务器，因此我必须找到解决方案。

您可以对

Net:：HTTP的给定实例禁用证书验证：

stock.verify_mode = OpenSSL::SSL::VERIFY_NONE

或者，您可以使用以下方法在流程中全局禁用SSL验证：

OpenSSL::SSL::VERIFY_PEER = OpenSSL::SSL::VERIFY_NONE

注意：Ruby解释器将警告您常量已经初始化。有时你可能会犯严重的错误。如果是这种情况，您可以取消分配常数并使用以下代码再次初始化它：

OpenSSL::SSL.send(:remove_const, :VERIFY_PEER)
OpenSSL::SSL.const_set(:VERIFY_PEER, OpenSSL::SSL::VERIFY_NONE) 

对于您的问题，这不是一个完美的解决方案，但如果安全性不是一个大问题，您可以使用上述方法绕过SSL证书验证。您仍将拥有到服务器的加密安全连接
 我应该把第二个放在哪里？如果您使用的是rails，那么您可以将它添加到初始值设定项中。否则，只要在开始使用
Net:：HTTP
之前执行一次，就可以将其放在任何需要的地方。在脚本中
需要'net/http'
后，脚本将工作
OpenSSL:：SSL:：VERIFY\u PEER=OpenSSL:：SSL:：VERIFY\u NONE
结果出现语法错误：
动态常量赋值
@bbozo您始终可以使用第一种方法禁用给定实例，但不能全局禁用（第二种方法更适用于开发模式，您仍在使用代码而不是生产服务器进行试验）。无论哪种方法，您都可以取消设置给定常量以避免动态常量分配。您可以尝试以下操作：
OpenSSL:：SSL.send（：remove_const，：VERIFY_PEER）；OpenSSL:：SSL.const_set（：VERIFY_PEER，OpenSSL:：VERIFY_NONE）
。确保需要
net/http
