博主在前几篇博客中介绍了小Q聊天机器人的源码及其包含的一些功能，并在应用市场上上线了一个版本，其中有一个功能是歌曲搜索，即输入格式为“歌曲#歌曲名#歌手”即可搜索出相应的歌曲并进行播放，不过最近两天在使用时发现一只提示“歌曲获取失败”，于是在代码中打印了一些log，发现该音乐搜索api（抓自百度音乐盒）失效，其实也不算失效，只是返回的数据为空了！不知道是间歇性的，还是百度发现后封了，或者更换了链接？如果因此砍掉小Q的歌曲搜索功能，那么可玩性就降低了好多，不好不好！那怎么办，接着抓呗~
至于抓包方法，不再写了，百度上多的是，博主也偷了个懒，也是参考了网上的相关方法，最终抓取到了千千静听的音乐搜索链接！不过，它这个稍有点麻烦，我们想要的是传入一个歌曲名即可得到音乐链接，而这个抓取到的没有直接通过歌曲名获得歌曲链接的方法，多了一步，即：先通过歌曲名获得歌曲id->再通过歌曲id获得歌曲链接：
第一步：获取歌曲id
参数query的value即歌曲名！
返回结果（json）：

第二步：获取歌曲地址
参数songid即歌曲id，从第一步获得传入即可！

歌词：lrclink；

其他字段就自己发掘吧~
好了，说了这么多demo何在？别急，先看效果图：
当然，这个也会有失效的可能，到时来一句偶滴老嘎，继续抓包呗！
