很喜欢www.sostart.com这个电台，于是想做一个它的APP玩

使用自己写的工具，flash cs设计界面，导出为cocos2d-x的jsb接口

设置了各种http header，依然无果

代码如下
···var xmlReq = new XMLHttpRequest();
var url = "http://www.sostart.com/api.php?_="+(new Date().getTime());
D(url);
xmlReq.open("GET", url);
xmlReq.responseType = "json";
xmlReq.onreadystatechange = function(){
D(xmlReq.getAllResponseHeaders());
if(cb){
cb(xmlReq);
}
}
xmlReq.setRequestHeader("Refer", "http://www.sostart.com/");
xmlReq.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:26.0) Gecko/20100101 Firefox/26.0");
xmlReq.setRequestHeader("Host", "www.sostart.com");
xmlReq.setRequestHeader("Accept", "application/json, text/javascript, */*; q=0.01");
xmlReq.setRequestHeader("Accept-Language", "zh-cn,zh;q=0.8,en-us;q=0.5,en;q=0.3");
xmlReq.setRequestHeader("X-Requested-With", "XMLHttpRequest");
xmlReq.setRequestHeader("Accept-Encoding", "gzip, deflate");
if (cookie) {
xmlReq.setRequestHeader("Cookie", this.cookie);
}
xmlReq.setRequestHeader("Connection", "keep-alive");
xmlReq.send();
···

依然无法获得在浏览器里得到的JSON

求解

xmlReq

setRequestHeader

Refer -> Referer

HTTP referrer header 的名字是 Referer。

要注意cookie，我用Python && requests库给你一个example

import requests
s=requests.Session()
s.headers.update({'Referer': 'http://www.sostart.com/'})
s.headers.update({'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/31.0.1650.63 Safari/537.36'})
# 保存cookie到session中
r1=s.get('http://www.sostart.com')

import time
r2=s.get("http://www.sostart.com/api.php?_={}".format(int(time.time())*1000))
print r2.json()

Out:
[{u'album': u'Origin',
u'artist': u'Evanescence',
u'cover': u'http://img3.douban.com/lpic/s2362221.jpg',
u'id': u'449',
u'source': u'http://sostartradio-songs.stor.sinaapp.com/201307/449.mp3',
u'title': u'My Immortal'},
