ruby - Rails3 omniauth google 身份验证返回用户身份

Question

我的 Omniauth 集成适用于本地开发，但无法用于谷歌暂存。

require 'omniauth/openid'
require 'openid/store/memcache'

Rails.application.config.middleware.use OmniAuth::Builder do
  OmniAuth.config.full_host = "http://xx.xx.xxx/"

  # dedicated openid
   provider :open_id, OpenID::Store::Memcache.new(Dalli::Client.new), :name => 'google', :identifier => 'https://www.google.com/accounts/o8/id'

end

我收到一条错误消息:

开始 GET "/auth/failure?message=invalid_credentials"for 58.71.19.178 at 2011-12-01 02:22:20 +0000 由 ErrorsController 处理#routing 为 HTML 参数:{"message"=>"invalid_credentials", "a"=>"auth/failure"}呈现 public/404.html(0.1 毫秒)在 1 毫秒内完成 404 Not Found( View :0.6 毫秒 | ActiveRecord:0.0 毫秒)

此外，我的 OmniAuth.config.full_host 中的 ip 也不相同，这可能会导致问题吗？

罪魁祸首是 apache 在不同的 ips 上发送和返回

这个猴子补丁解决了这个问题。
