无法通过护照获取facebook

Question

当我正在学习护照中间件时，我试图将它与新的Express 4 Router（）功能集成在一起。

但是当试图护照Facebook的中间件，用代码：

router.route('/auth/facebook') 
    .get(passport.authenticate('facebook', {scope : 'email'})); 

router.route('auth/facebook/callback') 
    .get(passport.authenticate('facebook', { 
     successRedirect : '/profile', 
     failureRedirect : '/' 
    })); 

我遇到了以下问题：

Error: read ETIMEDOUT

ETIMEDOUT可能是无效的redirect_uri，但从错误消息中很难分辨出来。
