无法从passport-facebook获取

Question

在学习passport中间件时，我尝试将其与新的Express4Router()函数集成。

但在尝试passport-facebook中间件时，使用代码：

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，但很难从错误消息中辨别出来。
