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。

},
