我已经集成了用于社交登录的 codeigniter 混合身份验证库。我已经为 facebook、google 和 twitter 创建了开发者密钥。当我尝试使用这些 api 登录时，出现错误。我在 localhost 中运行我的应用程序。将 url 重定向到 localhost 时是否有问题。

Facebook 的错误发生在我身上。我的应用程序已获得授权，但授权后 Facebook 未正确重定向。转到 Facebook>设置>应用程序并检查您的应用程序是否属于授权应用程序。如果是这样，请将其删除并重试。

You may face problem running Facebook and other third party authentications on local host, and it may be because of different reasons. One possible solution you can try is set a virtual domain to access your CI website. http://www.kristengrote.com/blog/articles/how-to-set-up-virtual-hosts-using-wamp gives very clear instruction to set up virtual host on WAMP. and then do our Facebook app's settings accordingly.

You may have to check if relevant ports on your localhost are open, otherwise you may face problem in receiving back the authentication.
