今天听了一天的歌曲，打算搞一个在线播放器，可惜要为歌曲烦恼，本来是打算想把歌曲下载下来放入到空间里面，可这样就会消费空间流量，于是就百度了一下百度音乐的MP3接口，有些是json返回获取，但我要介绍不是这款啦，这个感觉挺麻烦的，最简单的就是获取id咯，先给下链接

那么songIds后面的35509935是怎么获取的呢，打开你搜索的歌曲页面，如我搜索《想你 (????)》这首歌曲，他的链接是http://music.baidu.com/song/124002223那么请直接复制124002223这个，这就是songIds后面要输入的，然后访问就会返回一下信息：

xcode每秒自动更新一次，出现以上信息那就好办多了，访问songLink链接就OK了，这样歌曲就下载出来了，也不在将歌曲下载下来了，妈妈在也不用担心为歌曲下载而烦恼了
