有些地方代码有些冗余，还可以再改进  但是费了些功夫终于爬出的效果 确实想要快点编辑出来  按耐不住小激动  这应该就是敲代码的乐趣

当播放一个音乐的时候  在Elements中 可以看到音乐的链接  当然是通过js 和 css 加载过的   但是 可以用逆向思维进行参数的找寻

http://dl.stream.qqmusic.qq.com/C4000032qfIn1Tzdbq.m4a？vkey=80525033DD719DAB87C0CEC7B4F9F40D8755982D3A495E3BA0810E50A89668A2AFD61C4C19876FD0FB68932DED89B340AE9F4F464D82DC15&guid=7133372870&uin=0&fromtag=66

发现  vkey 是一个很重要的参数  所以就先去翻一翻网页查一下vkey在哪

经发现 在同播放页面的JS中   但是如果想获得vkey 就需要访问这个对应的URL  也要找到相应的参数

标红箭头的是一直在变化而且没有不行的参数

所以将继续往里使劲挖！

目前处于列表页  发现参数已经浮现

但发现第一个红箭头是歌手的意思  被不知道用了什么样的格式换了一种形式  因为后续还想通过段小乱码找到每个歌手所对应的歌曲 所以 还是找到每个歌手所对应的小乱码比较好

找到了！！！

但是 写代码的话 要用正向思维来写  Year!
