由于一些数据API未提供，所以想爬页面来获取。这是想要抓的页面 http://english.ctrip.com/hotels/shanghai-hotel-detail-436187/baoan-hotel/ 这个页面数据通过AJAX请求来获取。请求地址：http://english.ctrip.com/hotels/Detail/GetRoomDataJson4Hotels 参数：
var apiParams = { HotelID:436187, checkin:‘2015/05/10’, checkout:‘2015/05/11’, RoomQuantity:1, balanceperiod:‘M’ }; 我用https://github.com/request/request 这个模块来发起POST请求。我尝试了设置Referer，User-Agent,cookie等都无法获取数据没有报错，响应是成功的，body为空。不知道是什么原因？？很奇怪。希望高手指点。

@joney-pinkman 非常感谢，我要好好检讨一下我错在哪了，白白浪费了时间。
