所以我正在玩创建Facebook聊天机器人。为了与Facebook交谈，我需要验证我拥有我在Webhooks面板中提供Facebook的URL。
我有一条看似
的明确路线app.get('/api/verification', (req, res) => {
// Send back hub.challenge
});
所以在我从Facebook回来的req对象看起来像：
{ 'hub.mode': 'subscribe',
'hub.challenge': '178462834',
'hub.verify_token': 'my_verify_token' }
为了实现此目的，我console.log req.query并将其取回。但我无法转到req.query.hub.challenge，因为undefined因为hub.challenge是值名称而获得<IfModule mod_expires.c>
