与其他许多人一样，我遇到了 Ruby 的错误：SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed。

我下载了一个 cacert.pem 并尝试像这样添加它：

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

像这样：

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

我什至试图取消支票：

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

但没有运气（而不是你想要解决这个问题的方式）。奇怪的是它有时会起作用。

现在我正在尝试这个，但找不到证书：

require 'net/http'

url = URI.parse('https://www.xpiron.com/schedule')
req = Net::HTTP::Get.new(url.path)
sock = Net::HTTP.new(url.host, 443)
sock.use_ssl = true
store = OpenSSL::X509::Store.new
store.add_cert OpenSSL::X509::Certificate.new(File.new('addtrust_ca.pem'))
store.add_cert OpenSSL::X509::Certificate.new(File.new('utn.pem'))
store.add_cert OpenSSL::X509::Certificate.new(File.new('user_first_ca.pem'))
store.add_cert OpenSSL::X509::Certificate.new(File.new('xpiron.pem'))
sock.cert_store = store
sock.start do |http|
  response = http.request(req)
end

所以我https://myserver.com/Request.ashx在 chrome 中打开了请求，单击小锁图标以获取证书详细信息。但我找不到任何要导出的 PEM 文件。我可以看到它是 COMODO 证书。我不拥有服务器，所以我必须为此找到解决方案。

您可以禁用给定实例的证书验证Net::HTTP：

stock.verify_mode = OpenSSL::SSL::VERIFY_NONE

或者您可以使用以下方法在您的流程中全局禁用 SSL 验证：

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

注意：Ruby 解释器会警告你常量已经初始化。有时你可能会遇到硬错误。如果是这种情况，您可以取消分配常量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)

这不是您问题的完美解决方案，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 Cert 验证。您仍将拥有与服务器的加密安全连接。
