如何让Rubysspi 1.3.1与Ruby 1.9.3和Selenium Webdriver配合使用

我最近从ruby 1.8.7迁移到ruby 1.9.3，在退出代理服务器时遇到了麻烦。从命令行安装gems可以正常工作，但在运行“apply_sspi_patch”之后，应该会对http.rb文件进行修补，并运行“test_patched_net_http.rb”测试文件，我看到：

  1) Error:
test_net_http(PatchedRubyTest):
ArgumentError: Error occurred during proxy negotiation. req: nil; res: #<Net::HTTPProxyAuthenticationRequired 407 Proxy Authentication Required readbody=true>; Original message: wrong number of arguments (1 for 0)
    C:/ruby/lib/ruby/gems/1.9.1/gems/rubysspi-1.3.1/lib/win32/sspi/http_proxy_patch.rb:76:in `request'
    test_patched_net_http.rb:33:in `block in test_net_http'
    test_patched_net_http.rb:32:in `test_net_http'

• Rubysspi-1.3.1
• Selenium Webdriver-2.42.0

我通过修改gems\rubysspi-1.3.1\lib\win32\sspi\http\u proxy\u patch.rb文件缓解/消除了我的问题：

我在request方法中添加了一个retry（jretry），现在我再也看不到错误了

def request(req, body = nil, &block) # :yield: +response+
  unless started?
    start {
      req['connection'] ||= 'close'
      return request(req, body, &block)
    }
  end
  if proxy_user()
    unless use_ssl?
      req.proxy_basic_auth proxy_user(), proxy_pass()
    end
  end

  req.set_body_internal body

    req.exec @socket, @curr_http_version, edit_path(req.path)

    if tok = sspi_auth_required?(res)
      jretry = 2
      begin
